Presently, there are all sorts of devices that allow people to catch and analyze the spiders that live in their homes so as to find out whether they are poisonous or not. Quality photos or drawings as well as proper descriptions of the species are necessary when trying to distinguish between the various spiders that live so very close to us. Nevertheless, extreme attitudes towards poisonous spiders give rise to phobias and the urge to destroy their nests even in the wild. Keep in mind the fact that these creatures will not attack unless they feel threatened, as a human is no prey for their match. The harm the spider venom can inflict depends on the fierceness with which the spider will defend itself. A special feature of the wolf spider is the position of the eyes on the body; the four pairs are arranged in very unique ways, with four small eyes in a bottom row, two large ones placed in the middle and two middle-sized ones on the top row. The specificity of their vision organs is the one that ensures the survival of the species since the wolf spider depends on the eyesight to hunt. Thus, they may look more like spiders, but the visual accuracy is considered superior by many researchers. Camel spiders are more likely to hunt at night; they are nocturnal creatures that enjoy shady environment even if they mainly live in warm and arid climates. The preference for shade is the actual explanation of the impression lots of people got that the spiders may be attacking them. The treatment for special spider bites can only be provided in professional medical institutions since the risk the victim faces in most such cases is necrosis. What is the first aid procedure in case of spider bites? It all depends on the body part where you've been bitten; when the spider bites occur on the arm or the leg, tie a bandage right above the bite so as to prevent the spreading of the venom. Other measures meant to improve the victim's condition include the elevation or the immobilization of the body part if the bite has been made on one of the limbs. Though many patients fail to turn to medical intervention for the matter, the use of antihistamines, anti-venom and antibiotics can prove of great help.
