Donât let their cute little faces fool you. Mice and other pests in the RV can inflict great harm on your rig before you know what happened. They eat electrical wiring, chew holes in plumbing, and leave filthy poop everywhere.
Most RVers will square off with rodents inside the RV at one point or another. Hereâs how my husband and I have battled the buggers.
Why Itâs Easy for Rodents to Move Into RVs
Whether you own a motorhome, trailer, truck camper, or campervan, itâs so easy for tiny critters to climb their way into your home on wheels. RVs practically lay out the welcome mat for rodents. From hoses hanging outside the RV to undercarriage gaps on the perimeter of the RV footprint, our rigs have many open spaces that allow food aroma and warm air to announce âCome and get me!â
How to Welcome Mice Inside the RV
- Provide a warm space
- Park in a field, or go remote camping in the mountains
- Leave food out on the counter, and donât sweep crumbs off the floor
- Donât close up gaps around plumbing, propane lines, and undercarriage covers.
According to pest control experts, mice can squeeze into a 6 millimeter crack. Thatâs the size of a pencil! Watch this video of a mouse squeezing under a stick house door. See how they flatten their bodies to invade your home?
Any time you have a warm space with food inside and an easy way to get it, youâre welcoming rodents in the RV. Our tow or toad vehicles are also at risk. We once had a family of squirrels living inside the engine compartment insulation of our Dodge RAM truck.
Two Easy Ways to Prevent and Keep Pests Out of RVs
When summer turns to fall, start preparing to battle mice and rodents. This is the time of year they begin looking for safe hiding places in winter. Your comfy RV is an easy target if you are camping in the shoulder season.
Mice also love lonely, unused RVs parked in fields, with nobody around to intrude on their business. And sometimes, even RV storage businesses in urban settings arenât immune from hungry rodents looking for a safe place to live.
Your first job is to prevent mice from getting inside the RV in the first place. Weâve tried the usual ânaturalâ rodent repellents like peppermint oil and none of them worked. And we refuse to use rodenticides. Anything that kills mice by slowly setting their guts on fire is cruel. And rodenticides kill critical wildlife like birds of prey and coyotes who eat the poisoned rodents.
Seal Exterior Gaps to Prevent RV Rodent Invasions
The most earth-friendly and effective ways to keep mice out of RVs is to seal exterior gaps around the RV. We do this by applying Flex Mend Belly Bottom Repair Tape along any cracks where critters can get inside.
First, we stash bits of coarse steel wool in the crevices before sealing with the tape. This is another line of defense to keep pests out of RVs. They hate chewing on steel wool. Wouldnât you?
Clean any dirt or debris around the crack. Then seal it with the under belly tape you just purchased. This stuff is made of long-lasting polyester rip-stop material. The generous width makes it easy to apply. But use care: the adhesive is so sticky, the tape loves sticking to itself, to fingers, and everything else. Ironically, it loses adhesive strength if you place on a carpeted surface. In that case, youâll need to redo the job from time to time.
Next, Use a Non-Toxic Rodent Repellent
One of our favorite RV gadgets to keep pests out of RVs and tow vehicles is the Mouse Blocker. It comes in a version that hooks up to RV house batteries and car batteries. You can also buy a plug-in version.
Both use very little power, and both emit different levels of powerful ultrasonic frequencies to keep mice and rodents outside where they belong.
Between the under belly tape and the ultrasonic rodent repellent, anyone is well-positioned to keep pests out of RVs. Just remember to remove all food and crumbs if youâre storing your RV in winter. And if youâre living inside, keep all food inside sealed cabinets that donât have plumbing running through them.
When Mice Get Inside RVs
Thereâs nothing worse than waking up at night to hear little nails scratching on the inside of RV walls. When a determined mouse gets in, usually there is nothing more you can do than zap, snap, or trap and release the little devils. We once killed about a dozen mice in a few weeks. Turns out it was a mamma and her babies. Ugh!
If your RV mouse prevention efforts fail, consider RVing with cats for the ultimate in RV rodent elimination services.
