Haven't had rodent problems in my RV, however they do visit the garage and now I'm at war with these little buggers. It seems that our cat is not a good repellant after all. She's just not interested in them.
We have been told (and
here are proofs) that mice don't like the smell of Irish Soap. Any good luck with it?
We tried to stay humane, but as peppermint oil is certainly not going to work, I'm afraid we should prepare for the worst. I have already found that ultrasound repellers are not helpful.
