Question: What should I do if I have found a black widow spider in my  house?

ANSWER  The black widow spider (and the other species known as widow spiders) is not uncommon in many parts of the country.  It is usually found in undisturbed places around the house.  Common sites include wood piles, in and around downspouts , and in sheds.  Another common site is in crawl spaces, near the entrance and near the circulation vents.

While this spider can deliver a very toxic venom, it is rarely provoked to bite people.   The black widow spider makes a somewhat ”unorganized” web with a small central tunnel.  The webs are usually in secluded places.  Most often the female is seen in or near the web.

The tell-tale mark on the underside of the spider is not always an hour-glass. The marking is always red and the abdomen is always rounded and shiny, so this spider is easily distinguished from others.  The male spider and the young spiderlings are marked with red, orange, and white.  They are small, inconspicuous and not as dangerous as the female.

If there are black widow spiders around, then it is always a good idea to wear gloves when working in that area.  If a bite occurs, see a physician immediately.

An insecticide application around the outside foundation can help keep insects and spiders from trying to come inside. Follow label directions for mixing and application. Make sure that doors close snugly and are weatherstripped. Check crawlspace doors and vents to make sure they are closed or properly screened.  Move firewood as far away from the house as possible.
