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. Aloe vera, ice chips and antibiotics applied on the bite are thought to reduce the discomfort and speed up healing; yet, none of them is considered a 100% reliable remedy for hobo spider bites. You may even find brown widow nests in buckets, mail boxes, entry corners, closets, garages and even in vegetation like shrubs and tree branches. Most bites occur when one accidentally stick their hands into such secluded areas and corners or when the spider gets pressed against the skin. Wearing some rubber gloves when cleaning up around the house will help you avoid being exposed to a direct contact with the brown widow spider. 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. In terms of gender relationships, male spiders are famous for being killed right after intercourse, or at least this is the general myth people know. Since necrosis can appear in the worst of cases, doctors can sometimes take it for other skin problems caused by staphylococci or fungi. Hence, the ability to correctly identify spider bites is vital for the right treatment of necrosis. 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. Nevertheless, there is one other element that clearly makes the recognition of the brown recluse spider possible. One identification method used by scientists consists in checking how many pairs of eyes the species has; the brown recluse spider has only three pairs of eyes, unlike most other spiders that have four. 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.
