Black widows are the venomous spiders that build strong, messy webs in garages, woodpiles, crawlspaces, and outbuildings around CSRA properties.

How to identify the Black Widow Spider

Glossy black with a red hourglass on the underside of the abdomen. Females are the larger, medically significant sex.

Behavior & biology

They favor dark, undisturbed spots — under eaves, in woodpiles, garages, meter boxes, and crawlspaces — and build strong, irregular webs low to the ground.

Why Black Widow Spiders are a problem

Their bite is medically significant, causing muscle pain, cramping, and other symptoms that warrant medical attention, especially in children.

Signs of an infestation

Strong, irregular webs in low dark corners, round tan egg sacs, and the spiders themselves hanging inverted in the web.
