Many patients are yearly treated for the wrong affection because of the misidentification and misdiagnoses of spider bites. 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. In its natural habitat the species prefers rotten tree bark as the favorite place to make the nest, but it is also found in alls sorts of house corners. The only habitat specificities that matter are retreat and low moisture levels. Brown recluse spiders are not dangerous or aggressive; the only cases of bites occur when these creatures somehow get tangled in clothes, towels or even bed sheets. Thus, you may find brown widow spider specimens in a variety of colors from light tan to dark brown; moreover, all sorts of markings decorate their bodies making them all the more unique. There are red, orange, yellow, black and white patterns that the brown widow spider may carry on the abdomen, all of these features misleading any untrained eye. Webs are the distinct mark of spiders but even these have a particular imprint of their own: thus, some create sheet webs, others spiral webs, not to mention the true mazes that some dangerous species design as deadly traps for their prey. A clear example here is the distinct tangled web the black widow makes; yet, spiders also create webs for the protection of their nests. Since the favorite habitat of the huntsman spider is the forest, in many parts of the world it is known as the wood spider. The huntsman spider is easy to be taken for a tarantula, but it is harmless to humans; it never bites unless provoked, and the wound is superficial and healing in just a couple of days. 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.
