IS THERE ANY SUREFIRE SIGN IT’S A BLACK WIDOW SPIDER WEB? Inside the house, they might take up residence inside boxes, seldom-worn shoes and around the corners of rooms that don’t get a lot of foot traffic. Near the house, black widow spider webs can be found in and around garages, sheds, attics, crawl spaces, cracks in the foundation and underneath window eaves.

The central area consists of a tangle of threads, and the bottom portion of the black widow web is where the vertical ‟traps” for crawling prey are weaved.
