The most poisonous spider in Russia
Neither specialists nor ordinary people have any disagreements here and cannot be. Karakurt - of all the representatives of arthropods living in the vastness of our country, is the only one whose bite can be fatal.
Appearance
Danger to humans is represented only by females reaching sizes of 15-20 mm. They have two distinctive signs that do not allow karakurt to be confused with other representatives of arthropods. There are exactly 13 bright spots or dots on the upper side of the black abdomen. Naturally, there is no time to count them, but the very combination of black with bright spots should serve as a signal for danger. On the underside of the abdomen, there is one equally bright spot in the form of an hourglass.

Habitat
Karakurt are thermophilic. They live in the South Urals, the Caucasus and the Black Sea regions. However, in recent years, the habitat of this spider has spread to the more northern regions of Russia, up to the Moscow region. This is explained by global warming, but more optimistic scientists are sure that this happens only in very hot years, and even then not always.
Consequences of a bite
Karakurt, which has a very strong poison, unlike other spiders, is very aggressive and bites not only for self-defense. He can purposefully attack, so not only tease, but also approach him with great care. The bite itself is very painful, and after 10-15 minutes the pain spreads throughout the human body and becomes almost unbearable.
With untimely assistance, which consists in the introduction of a special serum, shortness of breath, nausea, vomiting, heart palpitations, fever, headache and dizziness, tremors, profuse sweating, and a feeling of heaviness in the chest may develop.
Even after the administration of serum, symptoms can persist for another day.
First aid
The only thing that can be done for the victim is to take him to the nearest hospital as soon as possible.

Other poisonous spiders of Russia
In the vastness of the Russian Federation, you can also meet with other representatives of arthropods, which are capable, if not kill a person with their bite, then cause a lot of painful sensations.
- South Russian tarantula. The venom of this rather large spider, reaching 30 mm in length, is not fatal to humans. However, the bite site swells very quickly and hurts a lot. An allergic reaction is possible in the form of rashes and redness of the skin, accompanied by itching and burning in the places of the comb.
South Russian tarantula - Heiracantium. Tops the list of poisonous spiders in central Russia. Unlike karakurt, it does not specifically attack and can only bite in self-defense. The symptoms are quite unpleasant: a strong burning sensation at the site of the bite, nausea, vomiting, headache, fever, body aches, weakness. The bite site itself looks pretty scary: it turns red, turns blue, and may even blister. This condition can last up to 3 days. Seeing a doctor is mandatory.
Heirakantium does not specifically attack people, but it can bite in self-defense.
- Phalanx (solfuga).One of the few spiders, after a bite of which it is recommended to suck the wound. It does not have its own toxic poison, but it will certainly carry an infection, as a result of which the wound will become inflamed. Shows activity only in the dark, but does not bite on purpose, only as a defense.
Phalanx - Mesh spider. A rather small spider, dangerous, like the previous representative of arthropods, not with poison, but with the possibility of introducing infection into the wound.
Net spider
Bagman (bag spider). This spider is aggressive enough to attack even in the absence of direct danger. The bite is not fatal, but it is accompanied by very severe pain, which can very quickly spread to almost the entire body.
Bag spider
• False black widow. First of all, it is dangerous because it often climbs into living quarters. After the bite, acute, prolonged pain, weakness and fever are felt. Symptoms can last up to two days.
False black widow
- Black fathead. The most peaceful of the dangerous spiders. If you do not touch it or pick it up, it prefers to hide. However, if it bites, the wound will hurt for at least a day.
Black fathead - Argiopa. The bite of this striped spider is very dangerous. An allergic reaction to poison can turn into deep and severe abscesses, a deterioration in the general condition and other unpleasant symptoms.
Argiope
As you can see, poisonous spiders are far from uncommon in Russia, but only the female karakurt should be very afraid. The consequences of the bites of other representatives of arachnids can be completely dealt with on your own. However, seeking medical attention is highly recommended.
Karakurt
Poisonous spiders of the Krasnodar Territory live in arid places, live in burrows underground, and do not build trapping nets.

After the bite, pain, swelling, redness, and swelling appear. After 15 minutes, the general state of health worsens - nausea, vomiting, pain in the abdomen, head, tremors, muscle spasms, difficulty breathing, increased blood pressure, heart rate increases. If medical care is not provided, cardiac arrest occurs or the person dies from suffocation.

First aid for a spider bite
Not everyone can distinguish one type of spider from another, despite the fact that the colors and patterns on their abdomens are different. And in terms of the size and length of the legs, they all differ from each other. However, people often start to panic and simply do not pay attention to what their abuser looks like.
Symptoms in most cases begin to appear rather quickly and first aid should also be prompt, but thoughtful.
- The first thing to do is rinse the wound with soapy water.
- The next step should be to prevent the spread of the poison. This is achieved in two ways: you should immobilize the affected limb with a splint and apply a tight bandage above the bite site, thereby reducing blood circulation.
- A cold compress should be applied to the wound itself, which will also delay the action and spread of the poison.
- Heavy drinking will also be a reducing factor. It will also help remove poison from the body.
- In order to relieve painful symptoms, you can give the victim an aspirin tablet.
Having done all this, you should not calm down.It is imperative to take the victim to the doctor, even if he is a few kilometers away. The clinic and help will be more qualified and will be able to take emergency measures in case of complications.
