Black widow spiders are known to be one of the most venomous spiders in the world, but with proper care and action, their bites are not life-threatening. These spiders are all black with red or orange markings on their backs and can grow to be up to 1/2 (13 mm) long with the female spiders being more venomous and 20 times bigger than the males. The black widow spider commonly resides in the southwest/south regions of the U.S. but can sometimes be seen in the northern part of the United States during the summertime.

Both male and female black widows will create funnel-shaped webs wherever they find a suitable place to live and stay away from anything harmful, but prefer areas that are dry, dark, and confined which can include your basement, plumbing, or wood piles. Be sure to keep an eye on these areas and if you find anything suspicious, contact Miller Pest & Termite to get rid of your infestation as soon as possible.
