Pest Control for Black Widow Spiders
Black widows are one of the most feared spiders in North America, because their venom is toxic. Black widows are very distinctive in appearance; they are generally black and have a red hourglass-shaped marking on the underside of their abdomen. Black widows generally nest in low areas, including garages, crawl spaces, and around the base of the home. You can identify a black widow web because it is irregular, and more coarse in appearance. Only females have the venom, and generally they are shy, except when egg-laying and guarding their eggs. If bitten, the pain is usually immediate and can last for up to 48 hours.
Here in the Triangle, Black Widows are very common. Many people have black widows, and they do not even realize it. Black widows avoid light, and they hide in sheltered places. They are active during the night.
I can personally attest to this. When we first moved into our house, I treated the perimeter of our home within the first week of living there. The next day, there were so many dead black widows around the house, I could not believe it. I would never have guessed that there would be so many, if any at all. Our daughter was very young at the time, and she enjoyed playing outside. I felt confident letting her play outside because our house was regularly treated.

Our general pest control program is designed to kill and protect against black widows spiders (as well as many other pests).
