Keeping pests out of a parked RV in Florida: close the doors they actually use.

A rig parked in Central Florida sits in year-round insect and rodent habitat. The oaks, the mulch, the warm compartments, and the quiet weeks between trips all invite tenants. Most infestations start small and specific: ants on a cord, a nest in a vent, droppings in a compartment. This guide works through entry points first, because a sealed rig needs far less pest control than an open one.

Entry points: where pests actually get in

• Appliance vents and exhausts. Furnace and water heater vents, the fridge vent, and the range exhaust are open tubes into warm spaces. Mud dauber wasps build nests in them during a quiet storage stretch, and a blocked vent becomes an ignition failure, or worse, on the first cold morning. Check every vent before the first propane appliance run after storage, as part of the wake-up order in our snowbird arrival checklist. Vent screens made for the purpose, fitted as the appliance maker allows without restricting airflow, are the common prevention. Never block a vent with a solid cover while the appliance could run.
• Plumbing, wiring, and cord openings. Where hoses, cables, and pipes pass through the floor and compartment walls, there are gaps. Sealing those gaps with a material suited to the spot keeps rodents and insects out without trapping moisture. Follow your rig maker's guidance around hot or moving parts, and do not seal a weep hole or a designed vent.
• Slide seals and door seals. A slide seal that no longer meets evenly, or a compartment door that does not latch snugly, is an open door at night. Our slide-out care guide covers seal cleaning and conditioning; a seal that is torn or permanently deformed is a replacement, not a cleaning.
• The bridges: cords, hoses, tires, and jacks. Ants travel along shore cords, water hoses, and anything that touches both the ground and the rig. During an ant problem, inspecting those contact points and breaking the trail, along with removing whatever the ants came for, matters more than spraying the interior.

Food and water: remove the reasons to stay

• Leave no food behind in storage. Take out pantry goods, pet food, and anything in a cardboard box or thin bag. What must stay goes in sealed hard containers. A rig stored with food in Central Florida is a rig stored with an invitation in it.
• Crumbs and spills count. Wipe down counters, the stove area, and the dinette before storage, and vacuum the corners where food collects. The cleaning that helps with pests is the same cleaning that prevents mold, covered in our mold and moisture prevention guide.
• Standing water is housing too. A sink holding water, a wet sponge left in the basin, a dripping faucet, or a compartment floor damp from a slow leak all draw insects. Fix the drip and dry the compartment; a dry rig is a far less interesting rig.
• Trash leaves with you. No bagged trash stored in a compartment, and no food scraps in an outdoor bin against the rig. At a resort, follow the park's trash rules and pickup rhythm rather than letting bags sit.

Rodents: read the signs before the wiring pays

• Look for evidence on every storage visit. Droppings in compartments and cabinets, shredded paper or insulation, stored bedding with nesting damage, and a sharp ammonia smell in a closed compartment are all findings. Photograph and note where you found them; the location is the entry-point clue.
• Chewed wiring is a repair, not a nuisance. Rodents chew insulation, and damaged wiring can short, overheat, or disable a system without warning. If you find chewed wires, do not keep energising that circuit and guessing. A mobile tech can assess the electrical damage on site; our electrical and plumbing page covers that side.
• Be careful with control products. Traps and baits each carry risks to pets, children, and wildlife, and resorts and storage lots often have rules about them. Follow the product label exactly and the park's rules, keep any product away from food areas, and consider a licensed pest professional for an active infestation rather than escalating home remedies.
• Vegetation and clutter around the rig matter. Brush, stored items, and mulch piled against the rig give pests a covered route to it. Keeping the area immediately around a parked rig clear, where the park allows, removes that cover.

Wasps, bees, and stinging insects

• Check before you reach. Compartments, the space behind the fridge vent, propane compartments, and awning rails are common nest spots. Open compartments slowly after a storage stretch and look before putting a hand in.
• Do not treat an active nest casually. A large or aggressive nest, especially near a propane appliance, is a stop-and-call situation. A pest professional or a tech, depending on the location, is the safer route than spraying around ignition sources or electrical equipment.
• Mud dauber nests in vents are a systems problem. A dauber nest in a furnace or water heater vent does not just block airflow; it is a common cause of a furnace that will not light after storage. Our furnace and water heater page covers how a tech clears and tests those appliances safely.

Call for help promptly if you find any of these

• Chewed wiring, burn marks, or a system that stopped working alongside rodent signs
• A furnace or water heater that will not light after storage, with a nest or blockage in its vent
• An active stinging-insect nest in a compartment or near a propane appliance
• Droppings or nesting throughout the living space, not just one compartment
• Ants or roaches that persist after food, water, and entry points have been addressed

Seal the gaps, remove the food and water, check the vents before the first appliance run, and look for evidence on every visit. Fitted into the weekly walk in our resort living maintenance calendar, those habits keep most pest problems at the stage of a finding rather than a repair.
