Hobo Spiders Living in both Europe and North America, hobo spiders are a species that prefers moderate climates, making their nests both in houses and outside, in gardens, hedges, fields and pastures. In the United States, hobo spiders are considered a real danger since their bite can cause severe necrosis; nevertheless, the reported cases are pretty rare, as the most likely symptoms to appear include local pain, itching and swelling of the bitten area. 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. The huntsman spider is also identified by its colors ranging from brown to gray; depending on the globe area where it is encountered, the species may present other specificities as well, such as hairy legs, as it is the case with the Badge Huntsman variety. Without detailed analysis, a correct identification cannot be performed, and it is usually for the professionals to succeed in such daring attempts. The mating period of trapdoor spiders coincides with the wet season when the males get out searching for a mate. Like with other spider species, the female sometimes eats the male, but the latter often escapes being eaten and manages to mate with several females before dying. 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. The most risky of situtations have been registered in the case of children under seven, who have been bitten by this insect; an equally high risk is present with people that have a very fragile immune system. The severest form that a brown recluse spider bite can get is that of necrosis when the deep tissues are affected and get gangrenous; the venom actually destroys the soft tissue, the area heals very slowly and scarring is inevitable. This unjust pattern is not justified since even the most poisonous spiders will not attack a human unless they felt threatened. All spiders need to inject venom in order to survive, it is in the nature of their species and one of the life mechanisms they have been endowed with; what really differs from one species to another and gives rise to the classification into poisonous and non-poisonous is the amount of venom and its toxicity.
