I had a pile of acorns on my E450 engine block! They got in and I tried everything. Dryer sheets, plug in devices, solar devices, sprays, poison, glue traps, peperment oil, scented packets, conventional mouse traps and even Have A Heart Traps. I also left all my cabinets and drawers open during storage so there would be no dark hiding places. I had an RV pad behind my house so checked on the RV weekly. I even adopted my neighbors 2 cats to help potrol the area. All these techniques helped. The final solution was to trade in the motor home. I hope there were no stowaways! P.S. To the new owners.......there names are Lucy, Ernest, Mickey and Ralph and they love Skippy Creamy peanut butter!
See you on the road!
