Xcluder Flying & Crawling Bug Barrier is an easy-to-use shield that controls pests and keeps mice, rats and other rodents, as well an array of flying and crawling bugs where they belong ? outside. The stainless steel wool with poly fibers is suitable for sealing various entry points, including roof lines, gaps around pipes and crevices in walls or foundations. Featuring an innovative blend of poly fibers and stainless steel wool, our mesh compresses into tight, narrow holes or crevices and then expands to fit securely in the opening, preventing pests from entering building interiors. Unlike regular steel wool, our stainless steel wool wont rust or corrode over time. Instead of struggling with messy foam, use Xcluder for a non-toxic and discreet solution to pest infiltration. Easy to use, simply measure and cut a piece of stainless steel wool from the 1-inch x 48-inch roll and pack into any opening, leaving no gaps or spaces for a permanent, impenetrable barrier. Guard your property before pests get in with our Flying & Crawling Bug Shield as the first line of defense against insects and avoid the use of poisonous sprays.
