GREAT STUFF™ Pestblock is the insulating foam sealant that blocks critters and bugs -- everything from spiders and ants to mice and rats -- from entering your home through gaps, cracks and holes. It's a distinctive foam specially designed to seal homes against insects and other pests as well as reduce air leakage.

  • Expands to fill, seal and insulate gaps up to 1" (25 mm) wide, forming a long-lasting, airtight and water-resistant barrier
  • Specially designed to block pests out of the home by eliminating points of entry
  • This foam is tack free in 10-15 minutes* (*Actual cure time depends on temperature, relative humidity and size of foam bead)
  • Fully cured foam can be trimmed, sanded, painted, and stained
  • Helps improve the home's energy efficiency by sealing gaps and cracks
  • Bonds with most building materials and surfaces
  • One 12 ounce can of foam covers the same area as 19 tubes of caulk
  • Designed for interior and exterior use* (*Skin of cured foam can discolor if exposed to natural light; paint or coat foam for best results)
  • Made in USA
