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.

I’m looking for a reliable spray foam insulation contractor in St. Peters to help with my home’s insulation upgrade. I want someone experienced, professional, and who uses quality materials. Energy efficiency is a big priority for me, so I want the job done right the first time.

If anyone has had a good experience with a local contractor especially with spray foam insulation contractor st peters, please share your recommendations. I'd also love to know about pricing, timelines, and how well the insulation is holding up over time.

Some types of foam insulation, especially when installed on exterior basement walls, can create hidden pathways for termites or ants, since they can tunnel through or behind it undetected. Pest control companies sometimes cancel warranties because they can’t monitor or treat effectively in those areas.

I used spray foam insulation on my garage ceiling about four years ago. At first, everything seemed fine, but last summer I started noticing a few ants and even some carpenter bees making their way into the corners. I was surprised, since I thought foam would keep all pests out, but turned out it’s not a perfect barrier. I talked to a pest guy and he said some bugs will try to burrow through foam if they really want to, especially if they were around before the foam went in. I actually started reading up on ways to stop insects in insulation and bumped into a lot of products on this site that use ultrasonic sound. Interesting ideas if you want something without chemical sprays.
