A parked RV or camper combines everything pests need: dark enclosed spaces, undisturbed storage areas, food residue from past trips, and dozens of unsealed entry points designed for plumbing, electrical, and slideout mechanisms. Mice are the #1 RV pest — they enter through slide-out gasket gaps, plumbing penetrations, and access panels, then nest in cushions, insulation, and stored clothing.
Remove ALL food. Every crumb, every spice packet, every forgotten granola bar in a cabinet. Mice can smell food through packaging. Remove pet food, birdseed, and anything organic. Clean all surfaces, including inside the oven and microwave.
Seal entry points. Mice need only ¼ inch. Check where plumbing enters from below, around slide-out gaskets (the #1 mouse entry on RVs), furnace and water heater vents, electrical hookup panels, and any access panel on the underside. Pack gaps with copper mesh or steel wool and seal with silicone or expanding foam.
Set snap traps inside. Place 6–8 snap traps along walls, under dinettes, and in cabinets. Use peanut butter. Check monthly if possible during storage season.
Apply CimeXa dust. Puff CimeXa into storage compartments, behind panel access points, and into any void space accessible from inside. It kills cockroaches, spiders, and silverfish on contact and lasts for years in dry conditions.
Moth prevention. Store any fabric items in sealed bags. Clothes moths and carpet beetles can destroy upholstery, curtains, and stored clothing during months of dark, undisturbed storage. Cedar blocks in closed compartments provide mild deterrence.
Leave cabinet doors open. This allows air circulation and prevents moisture buildup that attracts mold mites and silverfish. It also makes the interior less attractive to mice seeking enclosed nesting spaces.
At campgrounds: Park away from standing water (mosquitoes), tall grass (ticks), and overhanging branches (squirrels, ants). Don't leave food waste in the campsite overnight. Keep entry door screened.
Ants: Apply a thin line of CimeXa at the base of leveling jacks and stabilizers — ants climb these to reach the RV. TERRO bait stations inside for any that get through.
Wasps: Check under awnings, in exterior storage compartments, and inside slide-out mechanisms before extending them. Paper wasps build nests in these sheltered spots rapidly during summer.
Check for hitchhikers before departure. Stink bugs, spiders, and wasps often board during campground stays. A quick walk-through before driving prevents bringing them home.
