American house spiders, also known as common house spiders, are extremely common pests and may infest your home if the conditions are suitable. Here are three things you need to know about them.
What do they look like?
American house spiders have a distinctive body shape: their abdomens are round and held high above their heads. Their bodies can range in size from 3.8 to 6 millimeters long, depending on their gender, though their long, thin legs make them look larger. They have dark stripes on their legs and black spots on their abdomens; these markings are easier to see on darker individuals.
Unlike other types of spiders, both the male and female live together in the same web. Several egg sacs—which look like cocoons—can be seen hanging on the web. This unusual behavior can be used to help identify these pests.
Why do they infest homes?
A variety of pests, including ants and cockroaches, are attracted to human habitations. While these pests are annoying to people, they provide a steady food source for American house spiders.
If your house contains a lot of insects that American house spiders like to eat, your home will be able to support a larger population of these spiders. Since some pest infestations are hard to detect (like cockroaches) you may not even realize that you have a problem until you start seeing lots of spiders.
How can you keep American house spiders away?
American house spiders are well-adapted to indoor life, so it's very hard to keep them away entirely. Seeing the occasional spider is normal. However, if your home is infested with American house spiders, you can take steps to control their numbers.
Spraying the spiders with insecticides is just a temporary fix because it doesn't address the reasons their numbers became so large in the first place. To get rid of the spiders for good, you first need to control their food sources.
Insects need food, water and places to hide, and taking these necessities away from them will control their numbers. Here are some easy steps that you can take:
- Store your food inside glass or plastic containers
- Keep your kitchen as spotless as possible so that the insects can't find anything to eat
- Address any leaky pipes or faucets inside your home to reduce their access to water
- Get rid of clutter, like piles of boxes in your garage, so that they can no longer hide
Without their food sources, the American house spiders won't be able to survive for long, but to get rid of them more quickly, you can have your home sprayed with insecticides.
If you have a lot of American house spiders inside your home, address the conditions that are making the infestation possible. Visit an exterminating service like Cascade Exterminating Service LLC for more help.
