You Found A Spider Inside Your Home. Now What?

Most spiders you’ll encounter in and around your home or office are harmless. Even the large and frightening wolf spider is really all bark. However some, like the ubiquitous black widow, can be quite unpleasant. Easily recognized by the red or orange “hour glass” shaped mark on it’s abdomen, black widows should be avoided. A bite from a black widow can cause severe muscle pain, cramping, and nausia in healthy adults. You should seek immediate medical care for a bite involving infants, the elderly, or those with a compromised immune system as black widow bites pose significant health risks to these individuals. Usually described as “messy”, their irregular shaped webs are often found low to the ground and littered with leaves and other debris.
