Allen Special Products Stuf-Fit Copper Mesh

Unlike steel wool, which rusts and degrades when exposed to moisture, copper mesh maintains its structural integrity indefinitely. It won't stain your siding, brick, or stucco, making it a much cleaner and more permanent solution for exterior gaps.

Yes, the mesh is effective against both rodents and birds. Its dense, woven construction prevents small animals from chewing through or pushing past the barrier.

The material is highly pliable and can be easily cut with standard household scissors. Simply cut a piece slightly larger than the gap, fold or roll it to fit, and stuff it firmly into the opening using a screwdriver or putty knife to ensure a secure seal.

Yes, the mesh is completely non-toxic. It functions as a physical barrier rather than a chemical deterrent, so there is no risk of harmful residues or poisons.

While copper naturally develops a patina (a greenish-brown layer) over time when exposed to the elements, this process is purely cosmetic. It does not affect the material's strength or its ability to keep pests out.
