Great Stuff PestBlock Smart Dispenser is an expanding foam sealant specifically designed to block insects and pests from entering your home. This low-pressure formulation expands to fill, seal and insulate gaps, cracks and holes where rodents, ants, roaches, spiders, bees, mice and other common pests typically enter. By creating an effective barrier at these entry points, PestBlock Smart Dispenser helps protect your home from unwanted pest intrusions while also reducing air leaks and improving energy efficiency.
Unlike chemical pesticides, this foam sealant contains no pesticides but instead is formulated with a bittering ingredient. Once cured, the foam forms a long-lasting, airtight and water-resistant barrier that seals entry points where pests commonly try to access your home.
