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. A brown recluse spider bite gets painful and itchy within two up to eight hours from the incident. Experts in the field often say that spider identification is tricky since very many species resemble each other, and the venomous and the non-venomous ones are found in a complex who's who relationship. 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. 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. Even if hobo spiders live both on the American and the European continents, there is no difference in terms of physical specificity or venom composition. The treatment of the hobo spider bite is common with any other procedure applied to puncture wounds; let the bite bleed so as to eliminate as much venom as possible and then clean it with some topical antiseptic. Trapdoor spiders may also have parallel bars on the abdomen, but this is not always the case, since diversity is at home even within the range of the same species. Trapdoor spiders are not that easy to identify since there are other similar species for which they are often mistaken: the funnel-web spiders and the mouse spiders are the most relevant examples here. In the majority of cases the wound is likely to heal without any medical intervention whatsoever, however, the exception appears in the cases when the venom spreads in a blood vessel. It is not unusual to misdiagnose various skin infections as brown recluse spider bites, since the symptoms are very often miscellaneous.
