The Major Signs of a Spider Infestation in the Home

Did you know that around 3,000 species of spiders are found in North America? Even if you’re not an arachnophobe, this number is enough to make most people feel uncomfortable.

Thankfully, the majority of spiders aren’t dangerous at all. However, they (and their webs) can still be unsightly.

Are you wondering if you have a spider infestation or just a few extra roommates? Then read on. We’ll tell you all the major signs of a spider infestation so you know when you should call a pest control company.

Spider Webs

Spiders will spin webs to catch their prey. So if you start seeing more spider webs pop up, you should be wary, as this is a good sign that these 8-legged pests are moving into your home.

You should also inspect the outside of your property for spider webs in places like bushes. This can be a sign that they’re around your house and might move in at some point.

Do note that these shouldn’t be confused with cobwebs. These will be dusty, which means the spiders have abandoned them. So if you see cobwebs around your home, it’s probably a sign that you need to clean more, not that you have spiders moving in.


Of course, a big indication that you just might have a spider infestation is if you’ve been seeing them around!

It’s only natural that you see a few hanging around, as your house has much better conditions than the harsh outdoors. This is especially true if your house has been more humid and moist than usual, as this creates the perfect conditions for breeding.

If you’re constantly spiders all over your house, that’s probably a good sign that you have an infestation.

Egg Sacs

With the presence of spiders come their egg sacs. Spiders actually lay hundreds of eggs at once instead of one at a time. This means it should be pretty easy to spot their egg sacs. They should look like a silk ball.

If you spot these egg sacs, you should promptly get rid of them. The more time passes, the closer you’re getting to all of those eggs hatching. You might’ve guessed by now that you’ll be inundated with spiders, so if you didn’t have an infestation before, you will then.

Generally, spiders mate in the fall or anytime the temperatures become cooler from the summer. So be especially on the lookout during this season.

For those who’ve found egg sacs, you need to contact a pest control company immediately for spider control. Otherwise, you can quickly have a large spider infestation on your hands.

Mysterious Bites

This isn’t always a sign of a spider infestation, as many insects can bite you. And even if you have a spider bite, that doesn’t necessarily mean you have an infestation either. It can be just a random one or two in your home.

But if you’ve been waking up often with mysterious bites on your body, it can be a sign of a spider problem. At the very least, you have some sort of pest issue that needs to be addressed, especially if you or a family member is allergic to these bites.

It’s always a good idea to have a pest control company inspect your property if your family’s being bitten constantly.

Presence of Other Bugs and Insects

Again, it’s natural to have some bugs and insects in your home since it provides a good refuge from the outside. But if there’s a decent population of them inside, there’s a good chance you either have a spider infestation or are on your way to one.

This is because spiders love to feed on bugs and insects like ants, flies, and even other smaller spiders. So if there’s a decent population of these creatures in your home, you’ll want to be on the lookout for spiders since it’ll be a feast for them.

Spiders might start spinning webs next to or on your lights, especially outside. Many insects are drawn to light, so this makes your fixtures prime feeding spots for these 8-legged pests.

Look in the Right Places

All the above are signs of a spider infestation, and they’re pretty easy to spot. But just because you haven’t noticed these signs doesn’t necessarily mean you don’t have spiders around. And if their population is left unchecked, you might get an infestation later on.

As we’ve said before, spiders like humid and moist places. Not only that, but they like to hide, so dark areas are ideal for them as well.

Because of the above factors, spiders will take up residence in places like your basement, attic, closets, and any other storage areas. You’ll also want to check outside in places like your shed, furniture, and any cracks or crevices that lead into your home.

If you do have cracks and crevices, know that these can lead inside the walls of your property. So there’s a good chance that spiders might be hiding out in there.

Know the Signs of a Spider Infestation

While spiders are mostly harmless, it’s understandable that you’d want your home rid of them for peace of mind. So watch out for the above signs of a spider infestation.

And if you notice any, make sure you call a professional right away. Expert pest control companies can come inspect your property, determine how bad your problem is, and suggest the next best steps to take. They can even help prevent a spider infestation in the future.
