Any spider, or any insect for that matter, can find their way indoors. Most of the time if a spider is discovered inside, it's no big deal. They actually can help control some of the more problematic pests and spiders aren't usually too intrusive. Finding venomous spiders indoors is a different story and could result in an unfortunate incident if a bite is inflicted. 

Some of these species include:

Spiders Found Indoors and Dangers They Pose

Brown Recluse

Like most spiders, the brown recluse typically only bites when disturbred. The result can range from mild swelling and pain to severe tissue damage. The venom from these spiders can form a blister which can become ulcerated and then tissue damage at the bite area may occur. Most bites don't have this outcome and clear up within a few days. But those that do result in tissue damage can take months to heal. To lessen chances of unfortunate interactions it's important to be on the lookout. They like to hide in shoes or clothing that's been left on floors. 

Black Widow

Black widow spiders are notoriously dangerous and for good reason. If you're bitten the initial bite may only feel like a pin prick but their venom can result in a hospital visit. Swelling and severe pain are common symptoms. They like to nest in discreet places and may only be seen when disturbed. They generally will attempt to hide during these interactions and bites usually occur when they are accidentally stirred up by an unsuspecting victim. The most common places they are found indoors are in dark areas with minimal traffic such as the basement or a crawl space.

Black-footed Yellow Sac Spider

The venom from these interesting spiders is not as potent as the venom of a brown recluse yet it can cause similar reactions to the surrounding tissue. The bite can appear as a small blister and then begin to deteriorate the surrounding skin. This spider is somewhat aggressive and hunts its food rather than waiting for its dinner to get caught in a web. It's not uncommon to find them in homes, high up on walls, or crawling on ceilings. Black-footed yellow sac spiders may venture indoors during colder months in order to escape the elements. 

Spiders mostly want to avoid interactions and will typically hide from any human or pet that crosses their path. They can and do commonly find their way into homes and when this happens the risk of being bitten increases. Any suspected bite that is causing concern should be addressed with a medical professional. 

Although there are some actions you can take to deter spiders, the chances of seeing the occasional spider indoors still exists. They can sneak in unnoticed through many routes, such as on packages, clothing and shoes, just to name a few. Professional pest control is often your best line of defense.
