Went to check the van on Friday as it's in storage. Mice droppings everywhere. Fetched it home and set a trap. Bingo, caught one! We spent Saturday morning cleaning it out from top to bottom, took everything out, scrubbed and vacuumed everything. It looks brand new now. Then we heard another one scuttling along the roof lining. Bugger! Set three traps now and have ordered a sonic repeller due to come Tuesday. Let's hope that they work.
