Youโve undoubtedly used Dow Building Solutions products, though you may be more familiar with their Great Stuff brand. New to the Great Stuff line is Pestblock Insulating Foam Sealant. This sealant foam not only blocks air leakage points, but it also repels insects by adding chemicals. What Dow advertises, however, is that Pest Block does it without using pesticides. In this way, itโs beneficial to homeowners who want to avoid using pesticides due to concerns for their family or pets, or because ofย environmental concerns. Great Stuff Pestblock Insulating Foam Sealant contains Denatonium Benzoate, a bitter,ย non-pesticide. This additive has beenย used for years to make a variety of products, such as electrical wireย casing that deters pests and other animals.
Great Stuff Pestblock Insulating Foam Sealant Features
Dowโs Great Stuff Pestblock is explicitly designed to keep ants, roaches, spiders, bees, mice, and other rodents outside of your wall cavities and structures where they belong. Great Stuff Pestblock is designed more like their Window & Door sealant. It expands to fill, seal, and insulate gaps up to one inch (25mm) in diameter. The added benefit is that you can reduce or even eliminate the need to regularly reapply pesticides to select treated areas.
Weโve had a lot of experience inย weatherproofing and insulating homes. Homeowners who properly air-seal and insulate their homes can save up to 20% on heating and cooling costs. If all standard home wrap and insulation materials included pest-blocking properties, it would be a great improvement. Great Stuff Pestblock Insulating Foam Sealant is working itself into a plan of attack against pests that covers all the entry points where pests can enter the home. This includes:
- Gaps surrounding PVC pipes in the attic or throughout the home interior
- Openings around dryer and other exhaust vents
- Sill plates and rim joists
- Under baseboards
- Household plumbing and exterior water faucets
- Around attic hatch frames
Great Stuff Pestblock Insulating Foam Sealant is available at home improvement stores.
