Brown recluse spiders have a characteristic dark brown violin
marking on their back. These spiders often infest cedar shake roofs
and spin irregular webs, which are used as a retreat.
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
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
