How To use: EXpdandable Straw Foam
why expandable straw foam?
Rodents Away Odor Free’s Expandable Straw Foam is a durable, industrial-strength solution designed to fill, seal, and insulate small openings in and around your property once rodents have vacated the premise using our 4-Pack or 6-Pack of sachets. Additionally, it offers preventative benefits as well, not only reactive treatment of areas. The easy-to-use straw applicator helps you reach cracks and crevices where air, moisture, or pests can enter—creating a long-lasting barrier for indoor and outdoor use.
