Keeping Those Pests Away With Spray Foam Insulation

Spray foam insulation is a great choice for homeowners looking for an energy-efficient, long-lasting, and moisture-resistant insulation option. Moreover, spray foam insulation helps keep those nasty pests out of your home. If you have ever experienced the problems caused by a pest infestation, you know how helpful spray foam insulation can be. Pests can spread disease, cause allergic reactions, and damage your home’s structure or electrical systems.

Read on to learn how to prevent pest infestations with spray foam insulation.

1. Provides Your Home With a Barrier

The first thing you’ll notice when you investigate spray foam insulation is that it acts as a barrier between your home and the outside world. The first thing you’ll notice when you investigate spray foam insulation is that it acts as a barrier protecting your home from the outside world. This barrier is a physical barrier that can help to keep pests such as rodents, spiders, and other insects out of your home.

Pests have the potential to enter your home through small cracks, crevices, or holes. You might not see these tiny openings, but they are the perfect size for pests to slip into your home. High-quality spray foam insulation can provide a barrier that is tough to get through, making it an ideal pest prevention method.

2. Resists Damage Caused by Pests

Like any other pests, bugs, beetles, and cockroaches can wreak havoc on your home’s structure. If a large infestation occurs, the pests could chew holes through the walls of your home or chew through wires, causing costly damage.

Spray foam insulation helps protect your home from the damage caused by pests. The thick foam insulation can block out pests and keep them from chewing through the walls of your home. If the pests get through the insulation, the foam will give you more time to notice and react.

3. Prevents Drafts That Invite Pests In

Pests have a hard time surviving the cold weather. Mosquitoes, for example, cannot survive when the temperature drops below freezing. However, if you have a drafty home, you could be inviting these pests in by keeping your home warm for them.

In addition to creating a physical barrier between your home and the outside world, spray foam insulation can also act as a barrier to drafts. Air leaks and drafts commonly occur in homes through cracks in the walls or faulty electrical systems. These leaks and drafts can give pests an opportunity to enter your home.

Spray foam insulation can be a part of a pest prevention plan that involves other methods such as caulking, weather-stripping, and sealing potential entrances.

4. Cannot Be Eaten By Pests

Finally, foam insulation helps to keep pests away from your home because pests (especially bugs) cannot eat through it. If you have ever seen a spider or other insect trapped behind spray foam insulation, you know that they don’t have the ability to chew through it. Moreover, the hot foam expands when it is sprayed, creating a barrier that remains in place. Many pests would rather find food elsewhere than chew through the insulation.


The key to keeping pests away from your home is to prevent them from gaining access to your home in the first place. An easy way to prevent infestations is to invest in spray foam insulation. If you’re looking for an insulation option that will help to keep those bugs away, then spray foam insulation may be the perfect solution for your home.
