Will Spray Foam Insulation Keep Pests Out of the Home? [Video]

spray foam insulation  |  FAQ  |  home insulation  |  Pests


You are considering spray foam insulation for your home, but you want to know if it will keep critters out of your attic, crawl space, or house in general.

The most common places for pests like rodents, bats, and even bugs to get into a home is either through the crawl space and rim joist or through openings in the attic. When these pests are looking for a nice, comfortable place to stay, they are going to run along the outside of a structure until they find an opening.

Insulation in your home will not solve a pest problem that already exists, but it can help to prevent a future pest problem. If the critters are already in your home, it is best to hire an exterminator to serve them an eviction notice before you have foam insulation installed.

First and foremost, you should seal up any openings where these critters can get into your home. Once this is done, the addition of spray foam insulation can help.

RetroFoam of Michigan uses Icynene spray foam, which offers no food value to rodents or pests. Foam insulation does not create a complete barrier to their entry if they decide to gnaw through it though, according to Icynene.

The good thing about Icynene spray foam when it comes to pests, is that it does help to seal up those cracks and crevices where it is sprayed, making it more difficult for those unwanted house guests to get inside. Spray foam creates an air barrier that keeps the inside air where it belongs.

As the creatures search for drafts coming from your home, the spray foam’s barrier leaves nothing for the varmint to find.
