Stuff mouse holes
There are many ways to stuff holes that rodents would like to penetrate. Most of the remedies are simple steel wool, stainless steel wool or bronze wool. All of them are pure metals and therefore not really great to cut or deform so they fit perfectly in the hole. To stuff the holes is tedious.
There is now a filling fabric that has been designed for plugging holes against rodents. It's called Xcluder and is available online. It can easily be deformed and pressed into the holes and had sharp stainless steel fibers that the rodents dislike because they hurt themselves. It does not rust. I have sealed all louvers in the cracks of the house walls with it. Have fun with the "poetry".
Editor's tip:
The filling fabric recommended in this tip is available here.
