When you hear people talking about “house spiders,” you may be unsure of exactly what that means. Is that a species of spider or does that just refer to any type of spider that likes to live in houses? Well, it turns out that both thoughts are correct!
The Common House Spider
The species parasteatoda tepidariorum is also known as the “common house spider” or “American house spider.” When referring to this particular species, it is often best to use its scientific name because the term “house spider” is regularly used to describe many other house-dwelling spiders.
The common house spider is found throughout the United States. It is usually brown in color with spots that can be yellowish, dark brown, or nearly black. Its legs are also brown with darker rings of color on them. Common house spiders are relatively small, typically having a ¼” body or up to 1” when the legs are outspread. They also have a large, round abdomen. Parasteatoda tepidariorum produce tangled, disorganized webs that can be annoying, but this spider is not dangerous and will only occasionally bite in self-defense.
Common house spiders use their webs to catch and eat small insects like flies, mosquitoes, wasps, roaches, and more. They are extremely common throughout North America and can be found in places like basements, attics, garages, closets, wall voids, crawl spaces, sheds, and other structures.
General House Spiders
As mentioned above, “House Spider” is also a vernacular term for a wide variety of different spider species that are often found in human structures. Some of the most common of these spider species are barn funnel weavers, grass spiders, hobo spiders, black widows, cellar spiders, jumping spiders, wolf spiders, and brown recluses.
These types of spiders enter homes in search of food, water, and shelter. They prefer dark, sheltered areas where they can find refuge from the weather. Excess moisture and a ready supply of insects will also attract the spiders. To prevent spiders from coming into your home, try some of the following tips:
- Seal all cracks and crevices around the exterior of your home
- Make sure that doors and windows have intact screens
- Turn off outdoor lights
- Clean out gutters
- Fix leaky pipes and faucets
- Reduce clutter
- Store firewood away from the house and off the ground
- Remove spider webs from your property
- Inspect used furniture before bringing it into your home
- Reduce the insect population with good sanitation and/or pest control
