Went to the trailer today just to do a quick check and @#$%^& mice. First time in 11 winters with this trailer and never had them in the first trailer either. They are in one of the utensil drawer...
For cleanup use Nature's Miracle Urine Destroyer. It gets rid of odor and residue completely, which is vital if you don't want mice to return. If any odor remains, other mice will smell it and think that's where the party is.
