Spider Pest Control: How to Identify a Spider Infestation?

Spiders are one of the nearly common pests in the United States. While most spiders are harmless, there are a few species that can pose a threat to your health and your home. 

So, how can you tell if you have a spider infestation? Keep reading to find out.

Signs of a Spider Infestation 

There are a few telltale signs that you might have a spider problem. If you see any of the following, it’s time to call a pest control professional:

Spiders in Your Home

This one is pretty self-explanatory. If you start seeing spiders where they shouldn’t be—like in your kitchen or living room—it’s time to take action.

Spider Webs

Another sign that you might have spiders in your home is the presence of spider webs. If you start seeing cobwebs in corners or around baseboards, it’s a good indication of spiders nearby.

Spider Egg Sacs

If you see tiny, silken sacs in areas where spiders are active, it’s a good indication that you have an infestation. These sacs contain anywhere from a few to several hundred eggs, so they can quickly become a big problem if left unchecked.

Increased Insect Activity

Spiders typically only enter homes in search of food. So, if you start seeing more insects in your home than usual, it’s a sign that spiders are not far behind.


Some species of spiders can bite, and those bites can be painful and even dangerous. If you start seeing bites on your body that you can’t explain, they may come from spiders. If you have any considerations about an insect bite, it’s always best to consult with a doctor or medical professional.


Believe it or not, some species of spiders leave behind droppings. These droppings can harm your health, so you must clean them up as soon as possible if you see them or any spider pest control expert. 

Are Spiders Dangerous?

While most spiders pose no threat to humans, a few species can be dangerous. The two most common harmful spiders in the United States are the black widow spider and the brown recluse spider.

Black Widow Spiders

Black widow spiders are small, shiny, and black with a red hourglass shape on their abdomen. These spiders are found in all 48 contiguous states but are most common in the southern and western United States.

Brown Recluse Spiders 

Brown recluse spiders are brown or light gray with a dark brown violin-shaped mark on their back. These spiders are most common in the Midwest and the southeastern United States.

Both species can bite humans, and their bites can be dangerous—even deadly in some cases. If you think you’ve been bitten by a black widow or brown recluse spider, seek medical attention immediately.

While most spiders are harmless, it’s always best to err on the side of caution. If you think you might have a spider infestation, contact a spider pest control professional right away. They will be able to eliminate the problem cautiously so you can rest easy.


If you think you might have a spider infestation in your property, you should call a pest control professional immediately. They’ll be able to assess the scene and work out the best course of action for removing the spiders and keeping them from coming back. Don’t wait—the sooner you take action, the better.
