The bite of the brown widow spider is pretty painful, causing a lot of trouble to the victim, yet, it is not even by far as serious or as toxic as that of the black widow. There is a paradox related to the qualities of the brown widow spider venom: when compared to that of the black widow it is twice as potent. Unlike the general opinion that associates spiders with webs, this is not the case with the huntsman spider: this species goes out to hunt its pray as it doesn't wait for it to get caught in a web. Tree bark, crevices and even garages and sheds are the favorite places where the huntsman spider would make its home. In terms of toxicity, the black widow spider has one of the most potent venoms in the animal world: it is actually fifteen times stronger than that of the rattlesnake for instance. It also surpasses the cobra and the coral snake in the effectiveness of the poison. Though death is not usually the outcome of a black widow bite, some dozens of cases have been reported over the last decades only in the United States. 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. 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. The result of such a bite is known as loxoscelism, and it may appear in cutaneous and system manifestations. On a regular basis there should be no necrosis associated with a brown recluse spider bite, yet, some people are exposed to systemic reactions. 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.
