GREAT STUFF Pestblock 40-oz Spray gun Indoor Spray Foam Insulation Kit

Great Stuff Pestblock prevents pests from entering your home by sealing gaps, cracks and holes where they commonly enter. Pestblock is specially formulated with a bitter ingredient that prevents unwanted critters from chewing through the foam barrier. For stubborn rodents and varmints, insert the Copper Mesh into openings before sealing. Using our Pestblock Foam Sealant Kit is easy. Pop the top off the can; screw it onto the applicator gun; open the gun's valve; press the trigger and you're good to go! Still have foam left, leave the can attached to the gun and close the valve until the next use. Use the cleaner on the outside of the gun and clean the inside when you are going to store it for a longer time. After you use the cleaner, remember to remove the can and empty the cleaner from the gun.
