A bite exposes the victim to a whole series of unpleasant symptoms that require immediate medical intervention. 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 huntsman spider is easy to be taken for a tarantula, but it is harmless to humans; it never bites unless provoked, and the wound is superficial and healing in just a couple of days. The size of the huntsman spider may seem impressive, as it has no less than three centimeters in leg-span. The legs of the huntsman spider are actually the characteristic element for the species: rather than having them attached vertically to the body, they are twisted, with a crab-like appearance. Spider Bites Though most people fear spider bites because of the nasty symptoms associated with them, sometimes there is nothing to worry about, as a small skin wound is no threat for one's health. Not all spider bites are dangerous, since the majority of spider species are totally harmless for humans; with the exception of a few venomous ones, the rest are pretty safe. This is the case with the house spider, the giant house spider and the hobo spider; they all live indoors, but only the latter is a real threat to humans, since its bite can cause necrosis. In order to avoid direct contact with spiders indoors, you can use special sticky traps that will drastically lower the risk of being bitten by a venomous species. 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 human body represents a corner of shade, which will surely attract the spiders; this is the only explanation for the fact that these creatures get closer to humans in a variety of circumstances. All spiders depend on their venom for survival: venom is the way to hunt and defend themselves, but from the many thousands species only about two hundred actually represent a threat for human health. The great thing about these creatures is that they have adapted to the harshest of environments from the desert and the tropics to the Arctic areas where they can live underwater.
