Insects in foam insulation.

[Goodrunaway]

Hello..

Ive read some pest control companies are cancelling warranties for folks who have used spray foam insulation, or placed foam board on exterior basement walls because insects like to tunnel up in it. In your experience, is this a valid issue regarding foam, or is this misinformation designed to make foam insulation look bad?

Thanks

I have never heard of this and to my knowledge, most insects don't like foam as it is not a natural material.

I’ve heard the same thing about pests in foam insulation, and honestly, I think there’s some truth to it. We used foam board on the exterior of our basement, and a few years later, we noticed some signs of insect activity in certain areas. It wasn’t a huge infestation, but it definitely raised a red flag. After doing some research, we switched to cellulose insulation for better pest resistance and improved air circulation. It’s a natural material, so no issues with insects tunneling in, and it also helped with moisture control.

Ich hatte dieses Problem vor einiger Zeit selbst und konnte es zum Glück beheben.
