Sandy from Brooklyn writes
Pur Black Foam does not have any type of flavoring added to it. It is technically possible for mice to chew their way through the foam, but it is not likely. We have never had a report from a customer that a mouse had managed to chew through the foam. That being said, we do recommend putting the Stuf-Fit Copper Mesh into the hole first and then sealing with the Pur Black Foam.
