What Customers Are Saying
Customers overwhelmingly praise this pest-blocking foam for effectively sealing gaps and preventing insects and rodents, with many reporting dramatic reductions in ants, cockroaches, spiders, and mice. The reusable dispenser and precision nozzle are frequently highlighted as standout features, with users appreciating the ease of application and ability to trim and paint the cured foam. Most find it successfully fills cracks between one-eighth and one-quarter inch wide, creating airtight seals that eliminate drafts. A small number report dispenser clogging or inconsistent spray patterns, and a few note the foam appears cream-colored rather than gray. Despite minor drawbacks, most customers consider it highly effective and worth the investment.

Good product for filling gaps and keeping bugs out
Would RecommendWorks as described. I've used this to fill a lot of gaps between my interior and exterior where doors have shifted or cracks have appeared. Before covering them up with trim/caulk. It seems to keep the bugs out and fills the gaps to keep the air conditioning inside.

Dries yellow if exposed to sunlight
Would Not RecommendThis product appears to fill in the gaps around our basement windows okay but it will not stay grey in color with any sunlight exposure (turns yellowish). The dispenser attachment often popped off while applying the foam resulting in wasted material. I hope they redesign these cans and tweak the formula so the color actually stays the color that's on the label. Sure, you can paint the foam, but that's just extra work.
