I saw on some pest control tv show -- stuff the hole with coarse steel wool, then goop over it with whatever your exterior is. They just dont like the metal.

I have never order from them before, I just typed in crushed glass for sandblasting into google, because crushed glass is used sometimes in sandblasting.
