I discovered a small hole to the outside of our home that mice have been using as an access to get in. Is there a spray foam that is specifically formulated that has a metal or a fiberglas component or other special formulation that will prevent from mice from being able to eat through it? Also, the access I have to this hole is very tough so I would like to know if there is an extended nozzle 6 ft or so that I could use to pump this material.
