Keeping overgrown areas to a minimum helps prevents these spiders from nesting along the home.

Black Widow

The female spider earns its name because it typically eats the male after mating, leaving her a “widow.” The adult female Black Widows have toxic venom and are highly venomous to humans.

Look for a glossy hairless all-black body with a small red hourglass shape on the belly.

The best form of prevention for this spider is to minimize hiding places. Remove any extra yard debris, vacuum under and around furniture, regularly have web removal and pest control services done on your home.
