Do southern house spiders bite humans?

Answered by Willie Powers

Southern house spiders, also known as common house spiders or American house spiders, are typically harmless to humans. They belong to the family Agelenidae and are commonly found in homes and buildings throughout the southern regions of the United States. While their appearance might be unsettling to some, it’s important to note that they are generally not aggressive and will only bite humans if they feel threatened or cornered.

As an expert in spiders, I can assure you that southern house spiders are not known to be aggressive biters. Their primary prey consists of insects like flies, mosquitoes, and other small bugs that are commonly found indoors. They prefer to build their webs in undisturbed areas such as closets, basements, and attics, where they can easily catch their prey. In fact, having these spiders in your home can be beneficial as they help control the insect population.

However, it is important to remember that all spiders have the capability to bite, including southern house spiders. If a southern house spider feels threatened or provoked, it may bite as a defense mechanism. Their bites are generally harmless and rarely result in any serious medical complications. The venom of southern house spiders is not considered medically significant and is typically less potent than that of other spiders, such as black widows or brown recluses.

If you do get bitten by a southern house spider, the bite may cause some localized pain, redness, and swelling. Similar to a mosquito bite, the symptoms usually subside on their own within a few days. It is recommended to clean the affected area with soap and water and apply a cold compress to reduce any swelling or discomfort.

To prevent spider bites and minimize the presence of southern house spiders in your home, it is important to maintain cleanliness and reduce clutter. Regularly vacuuming, dusting, and removing spider webs can help discourage their presence. Sealing any cracks or openings where spiders can enter your home is also advisable.

Southern house spiders are generally harmless and pose little threat to humans. While they have the ability to bite if they feel threatened, their bites are typically mild and rarely result in significant medical concerns. Taking preventative measures to minimize their presence in your home, and maintaining cleanliness can help alleviate any concerns you may have about these spiders.
