Brown recluse spiders are nocturnal and eat other small bugs like cockroaches and crickets. These spiders spin irregular webs, which are not used for catching prey but rather as a retreat.


Brown recluse spiders often live outdoors where they are typically found around rocks, utility boxes and woodpiles. Indoors, brown recluses can be found in any undisturbed area, such as inside boxes, among papers, in seldom-used apparel and shoes, under furniture or in crevices of window moldings. Closets, attics, crawl spaces and basements are the most common brown recluse spider hiding spots.


Like the black widow spider, the brown recluse spider bites in defense and does not bite humans instinctively. However, both female and male brown recluse spiders can bite and inject venom. The brown recluse’s bite is usually not felt, but results in a stinging sensation followed by intense pain as long as six to eight hours later. A small blister usually develops at the bite location that can turn into an open ulcer. Restlessness, fever and difficulty sleeping are common symptoms of a brown recluse spider bite.
