Historical QOD 4/15/09: The bite of the brown recluse spider may result in a necrotizing lesion. The terms “loxoscelism”, “necrotic arachnidism”, or “gangrenocutaneous arachnidism” have been used to describe the clinical effects of envenomation from this spider. The clinical effects related to the bite include the necrotizing lesion and systemic effects, such as fever, chills, rash, joint pains, and hemolysis. What is the typical habitat for this spider and what are the behavioral characteristics that typify this spider?
Brown recluse spiders may be found indoors or out of doors. They prefer undisturbed areas, such as boxes or furniture in garages or basements. They are nocturnal and avoid areas of human and other animal activity. These spiders generally are nonaggressive and prefer dead prey. Their bites typically are defensive and usually occur when the spider is trapped against clothing or bedding.
