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. Homemade traps and low toxicity plant-extract pesticides are often used against the poisonous inhabitants of our houses that can give us some very nasty bites. The physical reactions to a spider bite are usually classified into local and systemic; the former can be treated at home right after the occurrence of the accident, whereas the latter often require professional medical treatment in order to reduce the reaction of the body to the venom. The local symptoms associated with a spider bite include pain, itching, redness and even swelling of the area; their intensity can be reduced if a tight bandage is applied above the wound. The bite of the brown recluse spiders is likely to cause a whole range of symptoms at the skin level known as loxocelism, and the greatest risk they involve is that of necrosis. Most bites are not only minor but also extremely rare; brown recluse spiders do not attack unless they feel threatened. As their very name suggests they enjoy very retreated corners where they are not bothered by light or intruders: cellars, garages, hallways or any other dark house area. The hobo spider is easy to recognize by the mixture of brown and rust shades; the species also carries another distinguishing mark: a herringbone pattern present on the superior side of the abdomen. Unlike other related species, the hobo spider isn't hairy; though the legs of these creatures are very strong and large, they are also very smooth. 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. In the open air, the brown recluse spider is to be found in rotten tree bark which they inhabit naturally without being disturbed. There is one thing that definitely sets the brown recluse spider apart from other fellow-spiders: the way it hunts. The whole purpose of weaving a web or creating a maze of threads is to make the perfect trap for catching prey; yet, the brown recluse spider does not consider that enough.
