There are several species of spiders that are considered common house spiders, but only one bears the name, common house spider. It is the spider species entomologists call Parasteatoda tepidariorum. You might know it as the American house spider.


As its name suggests, this is a common house spider in America. If you don't have ongoing pest control for your Dallas home, you likely have dozens of these spiders in your home right now. This spider species loves living with us so much, you would be hard-pressed to find one in the wild.
At this point, you may be thinking, "If I have dozens of these spiders in my home, where are they?" They should be crawling around everywhere, right? Well, they live mostly in the dark voids of your home and only come out at night to tend their webs.
Every once in a while an American house spider will hang out where you can see it. A common web location for these common spiders is between window panes and window screens. This is because it can be a place of high insect activity, under the right conditions.

What Do American House Spider Webs Look Like?

Some people call these spiders "cobweb weavers" because they are the spiders that make those spooky, Halloween-style cobwebs (not the pretty webs, like Charlotte, would make) but the ugly, tangled webs you find in storage areas and old abandoned mansions.

Do American House Spiders Bite?

Yes. This species of spider can bite you. The good news is that they don't prefer to. You can have one of these spiders climb on your skin and not get bitten. It is only when they are grabbed, squeezed, or startled that they bite. Most bites do not result in anything more than a raised, itchy, red welt.

How Do I Get Spiders Out of My House?

It is difficult to eliminate American house spiders because they often stay inside voids. They don't have to come out to find a bite to eat. Insects travel through the voids in your walls, floors, and ceilings and happen upon cobwebs made by these spiders. There are, however, a few things you can do to reduce house spiders. The key is to get rid of adult spiders and egg sacs by vacuuming spiders and their cobwebs up and disposing of the vacuum bag outside. This will prevent female spiders from mating and producing egg sacs and it will prevent egg sacs from hatching into hundreds of spiderlings.

The Benefits of American House Spiders

While American house spiders are creepy, and it is no fun waking up with an itchy welt on your skin, there are benefits to having these spiders around. They eat many insects that can be dangerous to you and your families, such as mosquitoes, cockroaches, and ticks. If you already know this, you may have already decided to allow these spiders to live with you, after all, an itchy bite is far better than getting West Nile or Zika virus from a mosquito, a bacterial illness from a dirty cockroach, or Lyme disease from a deer tick. You can protect your family from dangerous pests without having spiders crawling around inside your home. With an effective pest control plan, you can keep dangerous pests and spiders out of your home.
