  • Foam : PUR Black Gun Foam
  • Use Stuf-It Copper mesh wool to stuff into small cracks, to exclude rats and mice. Copper Mesh wire mesh will not rust and more importantly, the rodents can not chew through it. It is designed to fit into small cracks and crevices in order to stop the rodent entry.

    Another product to exclude rodents and rats from entering buildings is PUR Black Gun Foam. This is an expandable foam which bonds to surfaces. It is ideal in cracks or voids where rodents may enter.  Rodents can not penetrate this foam. It also keeps insects out.
