House Spiders

We have all seen cobwebs in and around our homes, and sometimes, we can even see who makes them. Some of us may not be bothered by spiders, but there are many people that find them quite frightening and would prefer not to find them around the house. You may be surprised to learn that this fear is usually misplaced, and spiders are actually very helpful and important to the environment.

One of their biggest benefits is that they catch other bugs that have also taken up residence in your home, such as ants, flies, roaches, and other nuisance pests. They would rather not come across humans at all, and like to hide in dark and secluded areas, ideally close to a water source or near where they can find their prey. In most cases, if you are dealing with a lot of spiders inside the house, it means there is another pest present that is providing food for them.

Types of House Spiders

Common house spiders come in a variety of colors and sizes, and are found in homes and residential buildings throughout the United States. They may build webs to catch insects or hunt for them along the ground, and all species will have eight legs and two body sections, the cephalothorax and the abdomen.

The most common types of house spiders are the American house spider, the wolf spider, daddy longlegs, sac spiders, jumping spiders, hobo spiders, black widow spiders and the brown recluse.

Are House Spiders Dangerous?

Most species pose no danger, but may bite if they feel threatened. The bites generally have mild side effects, such as some slight skin irritation and an itchy bump, or no side effects at all.

Brown recluse or black widow spiders are an exception to this, both of these species of house spider have venom that can cause dangerous symptoms in humans. Their bites are rare but if you are bitten, you should monitor it closely and seek medical attention if you have severe pain, abdominal cramping, a growing wound or increasing redness, and if you feel short of breath or have difficulty swallowing.

Even though the majority of these spiders are harmless, you also don’t want to be overrun by them and if you’re seeing more than the occasional house spider, you should call a pest control company.

Preventing and Controlling House Spiders

Make sure to clear any active webs or cobwebs you see around the house, and periodically check for webs in areas you don’t often go into like storage closets, attics, and garages. Once they are in places you don’t often use, left unchecked they will start appearing in the places that you do.

Spiders eat other insects, so it makes sense to take steps to prevent other bugs from nesting in your home. Keep sinks and counters clean, keep food properly stored in the pantry and refrigerator, and keep as much of the house as clutter-free as possible.

Other insects and spiders that are outside can get inside through open doors, windows, or entry points on the exterior of the house. Try to keep windows and doors shut as much as possible unless you have property fitted screens, and occasionally check that all seals and weather stripping are still in good condition. Check around the exterior of the house for any cracks or gaps, and make sure any weep holes around the foundation are filled with a sturdy mesh such as copper or steel wool to keep out spiders and other pests as well.

Regular pest control treatments from an experienced pest control company will also help to keep spiders under control as well as any other pests on your property that the spiders may be using for food. They can also help you sweep down spider webs from out of reach areas, like underneath roof eaves.
