Before placing a caravan or camper into winter storage, it is advisable to check ventilation grilles, seals around cables and pipes, and other openings. According to Rentokil, mice can enter through a gap of about 5 mm; Milieu Centraal states that a half-centimetre hole is sufficient. BOVAG recommends checking mesh in ventilation openings, and NKC advises removing food and crumbs. Rodent damage is often discovered only after winter storage; mice can damage insulation, cushions and wiring, leading to short circuits and fire risk. OHRA excludes pest damage from caravan insurance, and for campers coverage may be limited. One user reported about €2,000 in damage, but this is an individual case.
