GMT has developed Xcluder™ Brand fill materials as the next generation of rodent exclusion material. Xcluder is constructed with coarse stainless fibers bound together with poly fibers to form a highly resilient and absolutely impenetrable barrier for rodents. Rodents simply cannot chew or push through Xcluder! In addition, Xcluder is 100% non-toxic and harmless to the environment. Xcluder works by creating a dense fill of fibers that locks itself into an opening, permanently, and is an irritating surface that rodents cannot contend with. The stainless steel fibers do not rust or disintegrate so Xcluder stays in place indefinitely, yet can easily be pulled out, if required, for maintenance or any other purpose. No more messy expanding foam or tough caulk to remove!

Rodents get into buildings through existing openings as small as 1/4 or by gnawing and digging their own holes through walls, door frames, foundations or other barriers. Modern integrated pest management practices recommend that rodents be excluded from moving along their typical pathways and limiting their access to structures by sealing those openings with suitable means. Steel wool, copper mesh, caulks and expanding foams have been the traditional way to accomplish this exclusion, however, these products have various drawbacks relating to effectiveness, longevity or complexity of installation.
