 As the other said, bitter apple spray is pretty effective
This applies to just about any mammal. The problem with it is that it wears off really fast. You have to apply it ever day or two.
I have a screamer in the back of my desk. That works wonders. It scares the crap out of them when they go behind my desk, so they rarely do it anymore. I've used it for a lot of situations with my cats, dogs, and ferrets. I put it under my desk one day when one of my dogs got electrocuted from chewing wires I didn't even know she'd been chewing :S |
