You may have seen a spider wandering in your home or on a wall on occasion, but it's a different story if they have made themselves comfortable and settled into your home by building nests.

Some species of spiders are known to build small nests or sacs of silk in secluded, dark areas of your home, such as the corners of walls or ceilings. If you have encountered this, action must be taken quickly, or else the spider population will only grow inside your home.

Read on below to learn more about spider nests and how to remove them from your home permanently.

Identification

There are many different spider species capable of making nests. Some are sacs that they use to keep their eggs, while others are full-on webs that they settle in to rest or lie in waiting for prey. Some of the more common spiders known to invade homes and build spider nests are the sac spider, orb weaver spider, hobo spider, funnelweb spider, and cobweb spider.

Each spider species can be distinguished by how they weave their silk to make their spider nests. For instance, sac spiders spin webbing in a sac-like formation to store their eggs conveniently. The average spider can lay from a few eggs up to 1000, resting in the nest until the eggs hatch and little spiderlings crawl out in droves. When that happens, you will see many more spiders in your home.

Inspection

Inspecting for spider nests can be tough to find because of their small size and the areas in which they are commonly made, but by conducting a detailed inspection, you may locate the areas to treat.

Where To Inspect

Spiders like to make nests in dark, secluded areas in the home. They often make nests indoors in the attic, garage, or basement. They also make nests in corners of high ceilings or wherever there may be clutter. You may also find them outdoors in corners of your home.

What to Look For

You want to look for spider webs with small sacs of webbing that are cream-colored and round or oblong-shaped. Aside from nests themselves, finding little spiderlings crawling around is another sign that there may be a nest nearby.

Treatment

Once you have located spider nests, you can proceed with treatment. We recommend first using a spider-killing spray called Web Out and then following up by taking down the nests with a Cobb Webb Duster. Once that is done, we recommend spraying Supreme IT Insecticide for long-term control.

Step 1: Spray The Spider Nests with Web Out

Web Out is an effective spider spray that you can apply directly to the spider nest or sac. Its formula breaks down the spider silk materials and kills spiders quickly.

To apply, first, shake the product well. If you bought the 32 oz. ready-to-use spray bottle, the application is easy.

Just spray and shoot where spiders are found or where you have found spider webs and spider nests.

One quart should cover about 200 to 300 square feet. Spiders exposed to the product should die in just a few minutes.

Step 2: Take Down Webs and Nests with the Cobb Webb Duster Head

Spider nests and cobwebs are usually in high, out-of-reach areas, but with the Cobb Webb Duster Head, you can easily reach and take down those spider dwellings.

The Cobb Webb Duster head has special small nylon bristles perfectly designed to remove cobwebs and spider nests.

Are the spider eggs still too far for the duster head to reach? The Webb duster head has a threaded end that can attach an extension pole.

Step 3: Spray Supreme IT

Supreme IT Insecticide is our signature insecticide concentrate that controls various household pests, including spiders.

The best thing about it is that an application can remain effective between 30 to 90 days. 

Simply mix the appropriate labeled amount of Supreme IT in a tank sprayer with water and spray directly to where you have found the spider eggs and webbing.

A typical spot treatment will be 1 to 2 oz per gallon of water to treat 1,000 sq. ft. Spray along the eaves of your home, corners, along doors and windows, and points of entry.

Prevention

After the spider nests have been taken down and the infestation is gone, you will need to implement preventative measures so they don't return. Making your home less conducive for spiders to settle in and make nests is vital to keeping your home free of spider nests.

• Remove all the firewood and logs from your home. Keep your yard clean and remove dried leaves and organic debris from the grass. Furthermore, keep your yard maintained and trim overgrown foliage regularly.
• Remove extra piles of old papers, newspapers, cardboard boxes, bags, etc. to reduce clutter in the house.
• Make sure the cracks in the basement and foundation are sealed with caulk.
• If spiders often victimize your house, replace the standard lights with high-pressure sodium vapor or halogen lights. Light attracts insects at night, so as long as it is safe, keep the lights turned off at night or have them installed farther away from the door so that they illuminate the door and porch area.
• Spray a preventative treatment of Supreme IT around the house's perimeter to discourage spiders from entering the area and in places where you have seen the spider egg sacs. 

Key Takeaways

What are Spider Nests?

• Spider nests are temporary homes built by spiders using the silk they spin. They are usually set up in dark, secluded areas where they are unlikely to be disturbed.
• Spider nests found in the home usually indicate a large spider infestation that may develop if you don't take action. 

How To Get Rid of Spider Nests Quickly

• Locate the areas where you have seen spiderlings or webbing to find nests. These are outdoors around the exterior of your home or in quiet, secluded areas of the house.
• Apply Web Out spray to kill spiders and use the Cobb Webb Duster to wipe away and discard spider webs and eggs. 

Preventing Spider Nest Reestablishment

• Preventative treatment of Supreme IT will keep spiders away so they can't make spider nests.
• Decluttering the home and exclusion measures such as sealing cracks and crevices to take away points of entry can make it less likely that spiders will return and build nests.
