Hi,
Had a problem just before Christmas with Mice or a Mouse in the Motorhome at the storage facility, we cleaned up after it and disinfected everywhere, and then we put some Peppermint oil on cotton wool pads around the van which seem to have stopped them coming again ? hopefully
We also purchased one of those battery powered Mice repellent sounders as a second backup, not sure if they really work or not, but the peppermint oil appears to be doing the job on its own,
May be of interest to some of you.
