The Black Widow Problem
Black widow spiders are easily identified by their shiny black body and distinctive red hourglass marking on the underside of their abdomen. While they prefer to avoid humans, their venom is potent and bites require immediate medical attention.
In St. Louis, black widows are commonly found in dark, undisturbed areas: garages, sheds, woodpiles, outdoor furniture, and meter boxes. Our climate provides ideal conditions for them to thrive from spring through fall.
Female black widows are particularly dangerous as they're larger and more venomous than males. A single female can produce multiple egg sacs, each containing hundreds of spiderlings.
