Brown Recluse Spiders are light-to-dark brown, about 1/3 to 1/2 inch long, with a white, violin-shaped marking on their backs. The marking gives them the additional nickname of "Fiddle Spider." As their name suggests, Brown Recluse Spiders are often found in secluded spaces, like under rocks and in wood piles outdoors.  Indoors, they are often found under sinks, in crawlspaces and in boxes.

Damage From Brown Recluse Spiders

Brown Recluse Spiders are poisonous and while their first instinct is to quickly flee in an encounter, if they're disturbed or cornered, they can bite. Their venom causes a bad sore, and can lead to illness. In rare cases, Brown Recluse bites can be fatal. Irregular, gray webs and white, round egg sacs can be signs of the presence of Brown Recluse Spiders.
