Black Widow Spider

Physical Characteristics

The adult female is about 1/2" including an almost spherical abdomen about 1/4"-3/8" in diameter with overall length including legs of about 1 1/2"-1 3/8". Females are black in color with identifiable marking of a red hourglass.


Black Widow's can be found in irregular webs and hang upside down or in sheltered places, such as; under stones, firewood piles, under decking, hollow tree stumps, trees and rodent burrows. A favorite place is in barns, outhouses, henhouses, sheds, meter boxes, bricks, barrels and woodpiles.


Part of the Clark Pest Control's Pest-Away treatment is not only providing a residual barrier for the control of insects and spiders, but to physically sweep down all accessible spider webs.
