Why are we needed in nature and how are spiders useful for humans?

What do you think people are most afraid of - firearms or spiders? According to statistics, people feel more fearful when they see creatures with many legs and eyes. This is very readily believed, because seeing some of these creatures there is a desire to burn everything they touched. Scary-looking spiders live not only in warm countries, but also here in Russia. For example, recently scientists have discovered a completely new species of the so-called wolf spider, the mere sight of which can horrify you. Are you already wondering what they look like and how they can be dangerous?

Let's calm down first. In fact, if a wolf spider runs next to you in nature, you may not even notice it - the largest species grow up to a maximum of three centimeters. Most often, they live in grassy areas and wet forests, hiding in piles of fallen leaves and in burrows, shrouded inside by a thick layer of cobwebs. While walking through the woods, you will definitely not touch the web weaved by them with your face, because they never catch prey with their nets.

The most poisonous snake in Russia is the viper

In total, about 90 species of snakes live on the territory of Russia. There are about 16 types of poisonous among them. The most dangerous and widespread poisonous snake in central Russia is, of course, the viper. She lives both in forests and steppes. The viper is not too long a snake (up to 75 cm in length). Its color ranges from gray to reddish brown. The vipers are characterized by a dark line along their ridge, as well as an X-shaped pattern on the head. All vipers are already born poisonous.
When meeting with a viper, you should not make sudden movements, so as not to provoke the snake to defense. It is worth noting that viper bites cause quite strong pain. Swelling appears at the site of the bite. The most dangerous are bites to the face and neck.

And if you kill a spider?

If an arthropod is crushed by accident, and not deliberately, then the punishment is mitigated, and the signs in this case may not work. Also, murder can occur from severe fright. In this state, a person is not aware of what he is doing, so the reaction to this situation softens. The little corpse is advised to carefully take it out into the street and pronounce the conspiracy "Go away, at the same time take the bad with you into the night." It is important to clean it on the street, and not in a garbage can, otherwise the family will suffer losses.

In religion, there are rules for action:

1. Experience remorse, but strictly sincere. For the strength to make sure that the feelings are real.
2. Ask for forgiveness from the killed and from a higher power.
3. Then it is necessary to carry out an appropriate cleansing procedure in the church.

For an unbeliever, such rituals are irrelevant. But the mentality of a Christian assumes a tenderness of feelings for the murder of any creature. They sincerely believe that the consequences will be sad not only for the person himself, but also for his loved ones. Even if the omen does not seem to be something serious, then you should not play with the feelings of a person.

Proven Ways to Get Rid of Spiders

1. Remove spider webs, visible eggs and insects with a vacuum cleaner. This method is very effective if there are still few pests in the house. You can also use a broom or broom for this purpose, but the spider itself can easily escape, which is especially true for small individuals.
2. Place glue traps in dark corners, behind furniture, in closets, and near windows and doors.
3. Apply a long-lasting insecticidal spray to cracks and corners of the room. Follow the instructions on the packaging of the product to ensure your own safety and also not harm others, including pets.
4. If there are an excessive number of spiders in the home, call a professional exterminator. Keep in mind that professional pesticide products are highly toxic, so you will have to leave the premises for several days.

Important! Airborne fumigators are usually ineffective against spiders.

What happens to your body if you are bitten by a tarantula?

Tarantulas, in truth, have a terrible reputation - literally. They are big, furry and look menacing - for this they are adored by directors of horror films. Through a clever combination of arachnophobia and CGI, they have been passing off spiders as monsters for decades. As a result, a myth about the special poisonousness and danger of tarantula spiders has spread around the planet.

In fact, a tarantula sting is no more dangerous than a bee sting. Yes, it is unpleasant: pain, redness, burning sensation, a possible allergic reaction - everything is so, but not at all worse. And tarantulas kept as pets don't bite at all. In general, the reputation of these large furry creatures has suffered from their spectacular appearance, but they are not at all to blame for this.

Features

Spiders have eight legs, unlike insects. The forelimbs are equipped with chelicerae, which are poisonous claws. Arachnoid warts are usually located on the lower part of the body, usually 3 pairs. Some insects also spin cobwebs, such as caterpillars, but the spider web does not break under the force of prey, since it is elastic. On the head there are paired eyes, their number is more often 8 or 6, occasionally 2.

Digestion is of the extraintestinal type. For example, a praying mantis chews on caught prey, but spiders inject thinning enzymes into the carcass. After softening, they suck out the insides. Arthropods do not attack people or animals first, they bite only when they sense danger. If a spider falls on a person, then it must be blown away, but not beaten.

Males on the limbs in front have bulbs, they contain sperm for fertilization. Some males, after mating, flee and save their lives, others agree with the fate of the victim and allow themselves to be eaten. Compared to females, males live a little. Spiders are caring mothers, they weave small cocoons in the shape of a ball for nursing babies.

The spider can be found almost everywhere

Due to their diversity, spiders inhabit all regions of the planet, with the exception of the polar regions. Moreover, unlike most wild animals, they are not at all embarrassed by the neighborhood of people. Rather, the opposite is true: since flies, mosquitoes, midges love to crowd around human housing, be it a secluded hut in the forest or a skyscraper in the center of a metropolis. So, wherever you live, you cannot avoid meeting spiders.

Optimal conditions and terms for distribution

Spider - Haymaker is not poisonous, and is not dangerous for humans
Contrary to popular belief, spiders are not insects. Biology classifies them as arthropods. The lifespan of each of them depends on the species. Some exist for up to two months, others for several years, but due to the large number of natural enemies, few survive to a "natural" death. Scientists claim that some representatives live at home for up to thirty years.

In the warm season, in suburban conditions, spiders live in the garden and vegetable garden. Here housing and food are enough for them. With the onset of cold weather, they look for shelter and safely move into the house.Indoors they are more interested in solitude than in "communication" with people, so they often live in damp basements and dark attics than in living rooms.

But if spiders are still found in rooms, this means that they are attracted to prey in the form of insects. This is a signal that unwanted "animals", for example, cockroaches, have started up in the room. And if they are not visible, it means that the spiders are coping with them. Unfortunately, they cannot kill all pests, because they multiply faster.

Spider Feeding Portion Sizes

How much food can your spider eat at a time? Remember the main rule,

the volume of food should be 1/3 of the volume of your spider, and 1.5-2 times less than the body length of your pet.

The fact is that a large "lunch" can scare a young spider, and he will not receive anything but the strongest stress. Yes, and too large a "dish" is unlikely to be able to him. Although, some spider owners neglect these recommendations, and give the spider more insects than they themselves are in size. But, such a number will only work with an aggressive and hungry spider. Well-fed and contented only will be afraid of such an abundance of "game".

Harvesting food for the spider

Worms - food for the spider

In order for you not to have problems with what to feed your spider, we suggest that you start preparing food for it. This is much easier and more economical. And, since many spiders love to feast on marble cockroaches (not to be confused with domestic ones), however, they are not always available in the assortment of pet stores, we suggest that you start breeding such a colony of cockroaches at home. Even if something suddenly happens and they run away, they will not be able to live in your apartment, and will inevitably die. Therefore, you do not have to worry that you yourself have settled these insects in your house.

So, take a small container (glass jar) and put on the bottom of the lattice from under the eggs, cardboard, pieces of bark, paper - the more, the better, and regularly coat the edges of such a container with a thin layer of Vaseline (carefully so as not to get dirty) - this is so that your marble cockroaches don't escape. Launch several dozen of these cockroaches into such a container and feed them with leftover food from your table. Bread, cleaning vegetables, meat waste - cockroaches are not picky. These insects are very prolific and grow rapidly. Thus, you will solve the problem for a long time with what to feed your domestic spider.

By the way, when selecting food - give preference to wingless, not adults. This diet is suitable for growing spiders, but it can also work for adult pets.

How spiders eat

After the "lunch" has ended up in the spider's terrarium (it must be served there with tweezers), the hungry spider quickly rushes at it, grabs it with its chelicera fangs and injects poison into its body. Depending on the strength of the poison, after a few seconds, the victim's body becomes motionless. After that, the spider dances around the victim, weaves a rug from the web, or even braids the victim with a web. Then the gastric juice is injected, and the spider proceeds to the meal. He eats leisurely, so such a meal can drag on for several days. When a dry lump, entwined with cobwebs, remains from the prey, the spider takes it to the corner of the terrarium or throws it into a drinking bowl with water.

Instructions on how to find and deal with spiders, and whether it is worth doing

The sight of spiders scurrying along the floor in the apartment or along the walls in the bathroom, numerous stretched cobwebs in the corners of the house, insects that have fallen for this predator's bait - if all this does not horrify, then there is still little pleasant. The presence of these animals speaks of the disorder that covers the apartment.

But how to get rid of it is a completely different question.Basically, everyone always advises that you should not kill a spider, but rather take a newspaper or a stick and carefully take the spider away from the house to the street, but this advice is not always applicable in practice in view of the wild fear of these eight legs of this terrible creature.

The primary thought of the person who has turned his gaze on the spider is to kill, but this is only if the spider is large, with small problems usually does not arise.

Life of pests in the human environment

Ticks are also of great importance in nature and human life, but rather negative. Spider-like small pests are most often the cause of this or that disease. With the help of a tick, a person receives the pathogen, and that, in turn, is provided with good nutrition in the form of human blood. The most famous mites are the taiga and canine species. The first carries encephalitis, and the second tularemia and hemorrhagic fever.

The argas mite, which prefers a dry and warm climate, carries relapsing fever. The barn mite, living as a parasite on swallows, chickens, pigeons, transmits to us not one, but several viral diseases. Scabies itching multiplies in the human epidermis and causes scabies. Everyone has heard about the tick that lives in our beds, sofas and mattresses, it is called the bed tick. It feeds on exfoliated human skin (epidermis), causes allergic reactions and diseases, including bronchial asthma.

There are food mites, for example, flour or cheese mites, it parasitizes in some foods and can cause intestinal problems. By killing and damaging plants, fruits and trees, spider mites certainly provide the negative value of arachnids in nature and human life.

Safe views

Safe species of spiders in Russia hunt insects, waiting for a long time for prey to enter the net. For humans, their bites are not dangerous. These species live not only in nature, many live in yards, settle next to people in their homes.

The safe species of spiders in Russia include the following varieties:

• brownies;
• orb-webs;
• argiopa;
• knitters.

House spiders

This species prefers farm buildings and human habitation for habitation. It hunts for moths, bedbugs, cockroaches and other small insects. In nature, dense grass or a crack in the bark serves as housing. The variety is evenly distributed throughout the territory of Russia.

External signs of a house spider:

• the body is painted yellow with a brown tint, a brown pattern is located on the surface of the back;
• spider size from 0.7 to 1.2 cm, females are always larger;
• the legs are colored darker than the body, their length is about 2 times the size of the body.

Orb weaving in nature

The species lives in tree crowns, nets are placed between the branches, and the leaves are used to make a shelter

Wheel traps are immediately noticeable in a forest or garden. Sometimes round nets are placed under the eaves, in the window frames of abandoned houses

The poison is toxic to invertebrates and small vertebrates, it acts on rats, rabbits, mice, but horses, dogs, guinea pigs and sheep do not react to the bite. Muscles are blocked in the locust after 35 minutes, and the frog stops moving within 15 minutes. When bitten, the person experiences mild pain, but the amount of poison injected remains safe.

Orb-webs are distinguished by an increased appetite and eat up to 8 insects at a time. If the trap turns out to be unacceptable prey for him, then the owner breaks off the cobweb around, and the insect falls. In the same way, he does network cleaning.

Arthropod argiopa

Arachnids of this species are not dangerous for large mammals, animals and humans. Males are modest in size and rarely exceed 0.5 cm, while females grow up to 2.5-3 cm.The back coloration resembles a wasp due to the bright black and yellow stripes. Short hair grows on the chest and partly on the head. Long legs consist of several articular areas, are painted black with pale yellow spots.

Argiopes are spiders of central Russia, since they prefer areas with a temperate climate. They are also found in the southern part of the Stavropol Territory. The bite of an arthropod is compared to that of a bee, spiders do not attack first, do not show aggression. A slight pain is felt at the site of the lesion, swelling appears, but everything returns to normal after 2-3 days.

Trudovik knitters

The species spreads over the entire Russian territory and is found more often than in other countries. They almost always prefer nature and do not settle in buildings. For hunting, nets are made in a round shape with large rectangular meshes. The observer sees that such a product is not suitable for fishing because of the rare threads, but the whole point is in the specific victim that must get into the net. Knitters prey on long-legged mosquitoes, which are a favorite treat.

Knitter Description:

• the body is oblong;
• long legs are composed of jointed segments;
• many outgrowths are observed on chelicerae;
• females are large, reaching 3 cm, but males lose in growth.

The long torso saves the knitter in danger. At the moment of anxiety, he stretches his legs along the body and in this position resembles a dry twig. If disturbed in this state, the spider falls rapidly and quickly runs away.

How to feed little spiders

We already wrote that small spiders need to be fed more often, and their portions should be small. But where to get such small insects? If there is a shortage of this in the nearest pet store, we can help you out with practical advice.

Get ordinary large insects and ... cut them into small pieces. This is especially convenient with mealworms and zophobos. So, for example, one mealworm can be enough for a lunch for 6-7 spiders.

Some sources on spider science and the maintenance of such domestic spiders write that spiders can be fed with bloodworms - this is both convenient and practical. However, we would not recommend that you get carried away with such a diet. Yes, the spiders on the bloodworm eat off, begin to shed, but since the bloodworm itself, practically except for water, does not contain anything else in its composition, your spider on such "grubs" is unlikely to grow healthy, large and beautiful. So, think about what you want - comfort for yourself or health for your spider?

Internal structure

There is no complete circulatory system. Blood too. It is replaced by lymph. There are 3-4 holes in the heart, called ostia. Through ostia, the lymph from the body of the animal enters the heart, and from there, through the arteries, the heart drives the lymph into the gaps between the internal organs. From the intervals, the lymph enters the pericardial part of the body and returns again to the heart. The lymph has a mechanism that additionally supplies the spider with oxygen.

Spider structure

The respiratory system has a peculiar appearance. The lung sacs have plates and look like books. The breathing holes that open the lungs are equipped with protective caps. There are also long trachea tubes that transport oxygen from the holes to the organs of the spider's body.

As a predator, the spider has a well-developed central nervous system and a significant brain volume. In the cephalothorax of an arthropod there are 2 nerve nodes, from which many nerves diverge, leading to the organs of the spider. These nodes are the brain of the animal.

Where do spiders live

Spiders live everywhere and they are common in all corners of the earth. They cannot be found only in those areas that are under the shell of ice for a whole year. The number of subspecies in countries with hot and humid climates is much greater than in cold or temperate ones.These arthropods are terrestrial inhabitants (with the exception of only a few subspecies). They live in built burrows or nests, showing their activity only at night.

Tarantula spiders and other migalomorphic species live in the crowns of equatorial shrubs and trees. Drought tolerant species prefer ground crevices, burrows and other shelters at ground level. Digger spiders live in colonies, settling in individual burrows 0.5 meters deep. Some species of migalomorphs cover their settlements with special flaps, which are made of silk, vegetation or soil.

Haymaking spiders are very fond of settling in dark and damp caves, in abandoned old sheds and cellars, in dens, which were abandoned by animals. Longlegs can be found in residential buildings on the southern warm windows, hanging with their heads down.

But the jumping spider can be found anywhere:

1. In the highlands.
2. In desert.
3. In the woods.
4. On brick and stone walls of houses.

Karakurt can be found on wormwood heaths and fields, where pigs and sheep are often trampled by flocks, on rocky slopes of ravines, on the banks of artificial irrigation canals.

Side walk spiders spend most of their lives waiting for prey, sitting on flowers. But some representatives of this family can be found on the forest floor or bark of trees.

The funnel family places its web on the branches of shrubs or tall grass.

But wolf spiders prefer grassy damp meadows and wooded wetlands more. There they can be found in large numbers in fallen leaves.

The water spider builds its nests under water, attaching it with the help of a web to various bottom objects. He fills his entire nest with oxygen and uses it like a diving bell.

Spider breeding

As spiders grow, from time to time they shed their tight chitinous shell and overgrow with a new one. In their entire life, they can shed up to 10 times. Spiders are dioecious individuals, and the female is much larger than the male. During the mating season, which lasts from mid-autumn to early spring, the male fills the bulbs at the ends of his pedipalps with sperm and goes in search of the female. After performing the "mating dance" and fertilization, the male spider hastily retreats and dies after a while.

After two and a half months, the female spider lays eggs, and after 35 days, small spiders appear, living until the first molt in the web. Females reach sexual maturity at 3-5 years of age.

Among spiders, only poisonous ones are dangerous to humans. On the territory of the CIS countries, there is one such species - karakurt, or black widow.

With a timely injection of a special serum, the bite passes without consequences.

It has recently become fashionable to keep spiders at home. For beginners, a white-haired tarantula spider is recommended, which is a harmless representative of the arachnid class.

For its maintenance, terrariums are required, and as food, cockroaches, bran and finely ground oatmeal.

How do domestic spiders, wild

Arachnids do not have full digestive organs. The food is digested outside, after which the arthropod sucks up the liquid mass through the mouth opening. There are no teeth in the mouth either. Chelicerae, pedipalps, similar to tentacles, help to grind, grind food. Some spiders are only able to suck in liquid food, others - crush the shell, bite the skin. The kosinopez eats the victim entirely.

It takes longer for amphibians and rodents to digest. The predator eats a mouse, a snake, a frog gradually, turning it over in different directions, constantly injecting a new portion of saliva. How spiders eat flies can be seen in the video below.

The predator's diet depends on the habitat. Without food, an arthropod can stay for about a month. With a large number of insects, it feeds 1 time in 7-10 days.Some members of the family are so "greedy" that they do not crawl aside until they leave one shell or an empty space from the victim. In other cases, the loot is left in reserve.

Funnel spider can bite off a person's nail

Funnel water spiders are inhabitants of Australia, which is famous for many dangerous species of animals. They are sometimes called "leg-crippling spiders" - and for good reason. The size of a tarantula, these spiders are highly aggressive, especially during the mating season. At this time, they run around their territory in search of females and viciously attack anything that does not resemble a spider - including human legs. Funnel spiders have powerful jaws, with which they bite into flesh with such force that they can easily bite or even bite off a person's toenail. They do not want to let go of their victim, so the victim has to literally tear off the aggressor from himself with meat. So if you are thinking of a trip to Australia, don't plan it during the spider mating season!

Warm autumn - big spiders

When autumn is long and the temperature stays above ten to fifteen degrees Celsius for a long time, this pleases not only people. At times like this, you have the greatest chances of spotting large spiders in your home (especially if you don't live too high). Autumn is the breeding season for many species of spiders, so at this time of the year they crawl most actively everywhere, leaving their homes. And when the autumn is mild, there are a lot of insects, and spiders on such a diet grow to very large sizes.

So do not be alarmed: your furniture, windows, floors and walls in a warm autumn can easily become a meeting place for a fat spider and ... you.

Spiders

This order belongs to predators. Some people use sticky nets to get their prey, while others build cone-shaped traps out of the web.

The cross spider is a typical representative of the class. It catches its prey with the help of a stretched web. It is built like this:

• first, the animal pulls the non-sticky threads in the form of an irregular polygon;
• from the same threads stretches the radii;
• then, using an adhesive thread, a spiral is wound in a circle.

Further actions depend on which insects get into the net. For example, he will kill a fly immediately, and he wraps larger prey with cobwebs, turning it into a cocoon.

Side walk spiders are similar to crab - they move sideways with the help of widely spaced legs. Representatives of this family do not catch their prey on a cobweb, but calmly waiting for the victim. Their external coloration helps them to camouflage well, so that the victim does not see him.

Another species that hunts without a web is the vagrant spider. His delicacy is bedbugs that live next to humans.

Tarantula is one of the largest representatives of spiders in our country. Inhabits the forest-steppe zone near rivers, where there are sandy soils. He lives in a small burrow, which he makes in the soil. It hunts mainly at night, without leaving far from its shelter.

Karakurt lives in the steppe zone and semi-deserts. It is considered dangerous to humans. Its external signs: it has a black color, red spots on the bottom of the abdomen. The bite of this bite can even lead to death.

The tarantula is a spider that, contrary to its name, eats not only small birds. They hunt without a web, attacking from an ambush. This species can often be found among exotic pets. Prefers a warm, humid climate of equatorial forests. In Europe, they can be found in the south of Spain, Italy, Portugal.

How to feed a home spider

In nature, these predators feed on everything that moves, taking into account their size and measuring their capabilities. Living in your terrarium, which you have equipped for your domestic spider, such a pet can only rely on your choice in matters of its nutrition.Therefore, we would recommend that you consider the options for composing a feeding ration for your cutie spider from foraging insects. Such as Argentine, marble, Turkmen and other types of cockroaches (except for domestic ones - why? Read about this below).

Suitable for treats and mealworms and zophobas larvae. Where can you get all this? Good question. True, given the fact that now the demand for exotic pets has grown inexpressibly, then any self-respecting pet store in its assortment, in addition to food for dogs, cats and parrots, also offers food for spiders.

Spider Prevention

The following tips will help you take preventive measures against the appearance of spiders, both in an apartment and in a private house.

1. Don't let spiders get inside. Fill up all the cracks in the house or apartment, fill large gaps with putty. Replace or repair torn mosquito nets on windows and doors.
2. Turn off outdoor lighting: Spiders are not attracted to light, but it does attract other insects that spiders feed on. Also use curtains to dim indoor lighting.
3. Remove vegetation around the house, or move it to the other end of the site. In search of new food sources, spiders use bushes, flowers and other plants as hiding places and move through them into the building.
4. Keep the area clean. In a clean house, spiders will have no chance of hiding, which will not make them linger. Do not leave food debris around that will attract other insects. Sweep and vacuum floors regularly, and dust off furniture. Try to wash the dishes immediately after eating.
5. For food storage, opt for plastic containers over cardboard boxes, which are easier for spiders to get through.

How to walk without muscles in your legs? Ask the spiders

Spiders have very thin long legs that lack muscles. The spider controls them with a complex hydraulic system powered by blood pressure. When a spider dies, its legs curl up into a ball as the hydraulics stop working.

Spiders - what are: types

Researchers know about 42 thousand species of spiders. Spiders can be divided into three large suborders, which mainly differ in the structure of the jaws, more precisely, in the position of the chelicerae relative to the longitudinal axis of the body.

Suborder Orthognatha

More often, representatives of this suborder are called migalomorphs. They are characterized by the presence of thick hairs, large size and primitive structure of the jaws - the claw is directed downward and grows only on the upper jaw. The respiratory system is represented by pulmonary sacs.

Most migalomorphs live in warm climates. Burrows make themselves underground.

Orthognatha includes:

• tarantula spiders
• funnel spiders
• ctenisides
• spiders - diggers

Representative of the suborder Araneomorpha

Suborder Araneomorpha

Almost all other species of spiders known to naturalists belong to the large group Labidognatha or Araneomorpha. They differ in that they have claws equipped with both jaws. The respiratory system is represented by the trachea.

Types of spiders that catch prey without a net:

• spider crabs
• jumping spiders
• wolf spiders

Types of web spiders:

• linifed spiders
• tenet spiders
• funnel spiders, or brownies
• long-legged spiders
• orb-web spiders

Among the araneomorphic spiders, there are also those that are not able to produce cribellum, the substance from which spiders produce durable spider silk, and those who produce it.

Suborder Mesothelae

Lifistiomorphic spiders are distinguished by the fact that the chelicerae are spaced to the side, and not directed downward. This position is considered to be more evolutionarily advanced. But, this suborder is considered the most primitive, its traces were found in the Carboniferous deposits.Spiders have archaic pulmonary sacs, four pairs of arachnoid warts that have not yet shifted to the end of the abdomen. They live in earthen holes, which are closed with a lid. Signal threads radiate from the minks. Although one species prefers caves, where they make spiderweb pipes on the walls.

These include:

• spiders arthritis
• primitive arthrolicoside spiders
• primitive spiders arthromygalide

What to feed the spiders

A spider must eat to live
One of the most important topics in the science of keeping domestic spiders is feeding. Moreover, the importance of this topic extends to absolutely all types of home spiders - be it tarantula spiders, or any other type of these creatures. Therefore, today we will try to find out about the tips and rules for feeding spiders, and about what you can feed your furry pets, and what is not recommended to give them.

If you are planning to start a spider or have already started it, then you must familiarize yourself with this information without fail ...

Folk omens

Spiders for the most part are harmless animals, there are many signs about them among the people:

if a spider came to the house, luck came with it; spiders living in the corners attract all negative energy, preventing it from spreading to the owners of the house; if weaving a thick web - to drought; sits in the corner of a large web - to the rain; the spider seen in the bathroom warns against danger: something from what you have planned will not be beneficial, but harm; the presence of a spider in the house means prosperity; a spider crawling towards it promises a sudden profit. Creeping away from you - to expenses; if the arthropod scared you - bad news

But if you are not afraid - good news; if you notice a spider hanging from the ceiling on a string, pay attention to where it is moving. Up - to the fulfillment of desire, down - the dream is not destined to come true; a spider fell on your head? Expect enrichment soon; the earlier in time of day the little fly hunter met, the more negative the overall effect of the omens

Ideally, meet him in your apartment in the late evening; spiders cannot be killed - lose health and luck.

What do spiders eat in an apartment

Exotic pets eat everything they eat in the wild. The owners give their wards various insects, worms, snails, caterpillars, as well as small vertebrates, reptiles, and amphibians. Large animals are fed with rodents.

Domestic spiders that sneak into the room through open windows, doors, cracks in the wall, eat cockroaches, flies, fruit flies, mosquitoes, moth caterpillars, an accidentally flown butterfly, a wasp, a bee. There are many arachnids in houses with complete unsanitary conditions, many pests. Small spiders eat all the living creatures that are in the apartment.

Who spiders can eat depends on their own size. Small predatory individuals choose fruit flies, mosquitoes, caterpillars. A medium-sized arthropod can feed only on insects - it catches flies, bees, wasps. If too large a victim becomes entangled in the web, the spider frees it. It does the same with bedbugs, since they emit an unpleasant odor during self-defense.

Safe views

It should be noted right away that absolutely all spiders are poisonous, but only a few will be dangerous for human health - arthropods with highly toxic venom. In this chapter, we will look at those whose venom is deadly only to insects.

House spiders

These are perhaps the most famous and most common spiders living in Russia. They got their name due to the fact that they are very fond of living side by side with a person - they can be found in a private house, and in a city apartment, and in outbuildings. This spider usually weaves a web in the shape of a funnel in dark corners under the ceiling or in more secluded places, for example, somewhere behind a closet.The owner himself usually sits in the center of the trapping net and patiently waits for prey to fall into it. And as soon as the victim is in the web, the spider runs up to it with lightning speed and immediately straightens out.

You can recognize the house spider by the following features:

• integument is painted yellowish gray or brownish gray;
• there are usually brown spots on the back, folded into a pattern;
• legs are dark brown in color, their length is about twice the body;
• the size of the females is about 12 mm, the size of the male is no more than 10 mm.

Spider knitters

There are quite a few types of knitters, and these spiders are found in Russia more often than others. They are distributed throughout the country and live exclusively in natural conditions. Their trapping nets are circular in shape and very large meshes. Because of them, at first glance, it may seem that such a web is not suitable for hunting. However, it is not. The network is designed for a specific victim, namely, long-legged mosquitoes, which are a favorite treat for knitters.

The knitting spider has the following description:

• elongated body;
• legs are long;
• chelicerae are covered with numerous outgrowths;
• the size of females is usually about 10 mm, males are somewhat smaller.

How the spider kills its victims

Arachnids differ somewhat in their way of life, behavior, and hunting tactics.

• Animals, weaving trapping nets, wait for their prey in the center of their creation or in the immediate vicinity. The presence of insects is determined by vibration, vibration.
• They are actively looking for a victim, exploring the nearby area. They attack at the right moment.
• Some spiders do not weave trapping nets, but they build a web in the form of a funnel near a burrow, a refuge.

Predators also behave in different ways - they entangle their prey with their threads, leave them for a while, start feeding on insects almost instantly. However, initially, predators behave identically with their prey - they inject a poisonous substance.

All spiders have poisonous glands, kill insects, small vertebrates with chelicerae, which are located in front of the cephalothorax in the form of fangs. A poison with a paralyzing effect is injected into the wound, its own saliva, which turns the insides into a liquid mass.

It takes 5 to 15 minutes for the prey to become usable. All this time, the predator is watching insects, sitting aside. When the body stops beating in convulsions, the meal begins.

How does the house spider hunt?

The house spider goes hunting mainly at night, when it is dark, and it can catch prey not only with a web, but also without it. The web of this spider does not possess sticky properties; it has a thick dense layer.

When an insect hits the web, it starts to shake and vibration is created. The hunter quickly picks up the signal and gets close to the prey, plunges his sharp jaws into it, injects poison and digestive juices, which contribute to the liquefaction of the insides. The victim dies, and the spider carries her deep into the living tube. Digestive juices contribute to the liquefaction of the viscera, when they are partially digested, the spider sucks out the contents, leaving an empty chitinous membrane. On average, a house spider can catch about 10-12 insects per day. Of course, he will not be able to eat them right away, so the hunter makes supplies.

Sometimes the victim manages to defeat the spider and survive. For example, ants, despite their small size, fight a spider, which quickly exhausts it. Tired, the hunter can go into the tube, as a result, the ant remains alive and calmly leaves the cobweb.

The house spider does not live long in one web, since the remains of the insects caught by it accumulate in it. On average, the spider changes its habitat every 2-3 weeks.

As already mentioned, a spider can hunt without a web. In this case, he pulls two signal threads in a certain area. When the victim clings to the thread, the spider catches up with it and attacks.

The diet of a spider in a human dwelling includes fruit flies, large houseflies and other domestic pests.

Despite the fact that spiders are unwanted neighbors in an apartment or house, they do people a favor: they reduce the number of insects in the house.

Spiders: what is the use of them

As you know, a spider's web is very useful, for example, to catch up to four hundred insects, one spider will take only a day. Incredible, right? This means that all cobwebs on garden trees or fences, as well as shrubs, vegetable gardens, vineyards, are of great benefit for removing harmful insects. Since predatory animals appear in small numbers in spring, it is the best time for spiders to breed. Spiders tolerate cold weather quite firmly, so their work can last continuously all year round.

For a person, the harm from a spider occurs when he braids his home walls with his nets, of course, this does not look attractive at all. And the spiders themselves are not very beautiful, and some people are so frightened that they have a phobia. You need to be afraid of spiders, living in an area where they are poisonous.

The catch of a spider is usually flies, so if you are overcome by these annoying flying insects, then in no case drive out all the spiders, leave at least one. On a day, a spider can eat about as much as it weighs itself.

The most dangerous arachnids - interesting facts

Poisonous spider-like creatures are awake at night, at this time of day they hunt, getting their own food. Many species of these predators can easily do without water, feeding for several months in a row.

There are a number of other features of poisonous spiders:

• In nature, there are spiders of huge sizes. Galiaf can grow up to 33 centimeters in length.
• The most aggressive, dangerous for people is considered a wandering or banana spider.
• According to statistics, it is from this arachnid predator that people most of all suffer.
• According to researchers, spiders cause fear in 4.6-6.2 percent of the earth's population.
• Poisonous predators of almost all species are not averse to feasting on insects, even the smallest representatives of the fauna.
• Giant tarantulas love "food" more satisfying than small insects. The name alone makes it clear what they eat, except for birds, they love rodents, snakes, etc.

Bright tarantula spider

It is noteworthy that the natural web of an animal is considered one of the strongest materials. If you weave a thread of cobweb hairs as thick as a simple pencil, then it will withstand any load. According to the researchers, a high-speed Boeing at full speed will not be able to tear it. The multilayer webs that the predatory spider Darwin weaves are dense. If it was possible to fold them into a few centimeters thick tightly-tightly next to each other, then even a bulletproof vest would not compare with them in strength. In research laboratories, scientists are trying to reproduce a sample of the material, but so far, unfortunately, nothing has come of it.

As you can see, despite the fact that many species of arachnids pose a great danger to humans, there is still a lot to learn from these animals. Take care of yourself!

The spider is able to eat prey several times larger than itself

Spiders usually prefer small game such as flies or mosquitoes. But usually the spider web is much larger than is required to catch such game, and because of its strength, very large creatures sometimes get entangled in it - birds, bats, snakes and lizards. In this case, the spider is not lost - it wraps up the unexpected prey in a web more tightly, diligently pumps it with poison, and then begins to eat - slowly and with pleasure.

Safe spiders

This group of spiders should include those representatives who are either unable to bite through human skin, or their venom is too weak to harm. Spiders of this class include:

• Tarantula spiders.
• Cross spiders.
• Haymaker spider.
• Brownie spider.
• Horse spiders.

Spiders are of no interest to spiders, since their purpose is completely different - to live in nature so that no one touches them.

Tarantula spiders

These animals represent a group of the largest spiders on the planet, of which the goliath spider is considered the champion. Its size is simply amazing - about 10 cm, and the paw span is about 28 cm. These spiders are also distinguished by the fact that their body is covered with thick wool of red-brown shades. For a person, this monster is not dangerous, but its falling bristles can lead to various allergic reactions.

Spiders cross

They are considered relatively large representatives of their genus. You can easily distinguish them from other types of spiders by the characteristic pattern in the form of a cross located on the back of the animal. It is a typical representative of gardens, parks, forests and other green spaces. He uses a cobweb as a tool for catching food. The spider itself may be in a shelter of old leaves.

Spider bites are not dangerous even for children, but he can let the child know so that he does not touch him.

Haymaker spider

This living creature with long legs constantly annoys a person by constantly weaving a web, which has to be constantly removed. He prefers to live in houses or apartments, but he can also be found in other outbuildings. Not dangerous to humans.

House spider

Represents the funnel spider family. The family got its name thanks to the weaving of funnel-shaped spider webs. It can often be found in a person's home, as well as in other places. The female grows in length up to 7 - 12 mm, and the male is more modest in size - only 6 to 9 mm. The body of the animal has a brown tint. In relation to people, he does not show aggression, but if you disturb him and stick your finger into the shelter, then he will surely bite. In this case, there will be no negative consequences from the bite.

Jumping spiders

They represent one of the most numerous families. Found almost everywhere except Greenland. They differ in that they can jump, while they go hunting mainly during the day. The horses are also distinguished by the unique structure of their body, namely, by the presence of a kind of hydraulic system. Thanks to these possibilities, which allow regulating the pressure in the circulatory system, spiders can perform jumps incommensurate with their own parameters.

Peacock spider

A unique species of spiders representing the racehorse genus. This small living creature is endemic to Australia, therefore it is not found anywhere else on the planet. This unusual creature got its name due to the fact that it practically copies the behavior of the most beautiful bird. At the same time, the male also has brighter colors than the female. During mating games, the male spreads his tail, and also uses the side shields located on the abdomen. Together with the hind legs, he lifts them up. If the female is not present, then the males wrap the shields around themselves.

Spider tramp

They do not weave hunting webs, but hunt various insects from an ambush. By the nature of the hunt and the structure of the eyes, they can be compared with wolf spiders. The female nevertheless weaves a web, but for completely different purposes - forming a cocoon, she lays eggs in it. At the same time, she carries a cocoon behind her back.

Hunter limb

It is a family of hunting spiders and can grow up to 2 cm in length. It is distinguished by a yellow-brown body color, although depending on habitat conditions, the color may have darker tones. A characteristic feature is the presence of a white stripe on both sides of his body. Prefers to settle on the banks of various reservoirs located in the temperate zone of Eurasia. The species is quite unique, as individuals can move through the water and even dive if necessary. It has another name - the angler spider, as it can hunt for fish fry.

Spider green

In fact, this species does not exist in nature. Various spiders belonging to one or another genus can have a similar color. For example, green can be:

• Jumping spiders.
• Hunter spiders.
• Lynx spiders.

To find out how dangerous a green spider is, you first have to decide on its appearance.

Crab spider

This type of spider also does not exist, but some of the species can move sideways, like crabs. For example:

• Neocribellatae species.
• Thomisidae species.
• Philodromidae species.

Spider water

There must always be a container with fresh and clean water in the terrarium, which is recommended to be changed daily. And, if a spider can exist for a rather long period without food, then without water it will not live long.

To prevent water spilling and the spider in the terrarium does not spread the "swamp", pour water into a special drinking bowl.

Should you be afraid of spiders?

Almost all residents of apartments and private houses faced the problem of the presence of spiders. Good or bad depends on how knowledgeable the tenants are about these insects. Of course, they look terrifying, indicating that the spider must definitely bite. It is this fear that always lies at the basis of the fight against these insects, although no one thinks why the spiders appeared in their home.

There are many myths and many superstitions associated with spiders that speak of completely opposite factors. For centuries, the spider has been a manipulative tool for sorcerers and fortune tellers.

Many of them saw positive qualities in the spider, and some of them awarded spiders with exclusively negative qualities, and this formed the basis of the fears of many housewives. And this is not surprising, since since childhood everyone has been told tales about man-eating spiders, etc.

Therefore, the attitude towards spiders is formed on the basis of knowledge or on the basis of superstitions, which always have two sides of the coin, depending on the personal attitude towards arachnids. Some see them as some kind of sign indicating profit, good luck, or a meeting with the person of their dreams, while others see adultery, a long journey, illness, failure, etc.

Is it necessary to exterminate arthropods

Cobweb-covered corners, windows and ceiling look messy. If there are a lot of spiders in the house, it means that the cleaning there is of poor quality, ignoring hard-to-reach places.That is why, when asked whether it is necessary to look for a remedy for spiders, the answer will be in the affirmative. It is possible and necessary to fight arthropods, but it is better to do it humanely, especially if the goal is not to harm living beings.

On the street, spiders winter under the foliage, in warm corners behind the bark of trees, so you can release them from home at any time of the year.

Considering how long spiders live (usually no more than a year), one might think that it is pointless to fight them. Nevertheless, one must remember about the ability of arthropods to actively reproduce. The new generation of spiders will replace the old one so quickly that it will be almost impossible to achieve cleanliness in the house without cobwebs and dry bodies of their victims without special means.

The most effective chemicals are:

• "Butox 50".
• "Neoron".
• Dry trap tablets.

"Butox 50" is a simple and affordable product, easy to use. Apply it after carefully studying the instructions on the package. To achieve the result, it is enough to spray the surfaces where spiders are often found, first preventing the flow of clean air through the windows and doors. After the end of the action of the agent, the room is ventilated.

The drug "Nero" enjoys well-deserved trust among specialists. Just as in the previous case, it is necessary to study the instructions for using the tool. In places where food, children's toys, utensils are stored, the product is used with extreme caution, protecting vulnerable things and products with film.

An alternative to aerosols often with a pungent odor will be tablets, they are also traps. Produced in dry form, they lure spiders, after which they are poisoned with poison. The method is simple and effective, but far from humane.

If you notice only one spider, you can carefully take it out into the street. The house spider is not capable of causing harm to humans. But what if there are a lot of spiders, and this has turned into a problem? In this case, both chemistry and folk remedies will help in the fight against them.

The chemical industry is represented by a huge variety of all kinds of means for dealing with unpleasant tenants. These are sprays, solutions, and traps.
