Pesty Buggers: How to Keep Mice, Bugs & Critters Out of Your RV the Non-Toxic Way

Pesty Buggers is sponsored by RV Roofing Solutions — keeping RVers protected on the road.

The Night a Mouse Ate My Lemon Oreos

 Okay, friends. Let me set the scene. We had just pulled into the most beautiful site I'd ever seen — wildflowers everywhere, an old barn up on the hill, a little vegetable garden, the whole storybook. We'd lost our cat, Edward, a couple of weeks before, and I needed that view like I needed air. This felt like a place where my soul could finally rest.

And then, a few nights in, I reached into the pantry for a couple of thin lemon Oreos. Just a little evening treat. The package looked...disheveled. I pulled it out, and there they were: tidy little nibble marks running all the way down every single row. A farm mouse had found our trailer, found our pantry, and found my Oreos. Reader, it destroyed my healing process.

Here's the thing I had to admit in that moment: Edward had been our pest control. With him gone, our rig was fair game. (Shout-out to Ralph, the park cat/manager, who eventually caught the culprit and left him on our rug like a trophy. Ralph, you are a gentleman.)

So Jennifer and I sat down to talk about the thing every RVer deals with eventually and nobody loves admitting: the pesty buggers. And because we live in tight spaces with kids and pets, we kept the focus on family-safe, low-tox ways to fight back.

"It literally ate the sealant off like frosting." — Jennifer, on the raccoon no one saw coming

What This Episode Is About

Part horror story, part group therapy, and entirely useful, Jennifer and I trade our most unforgettable run-ins and then get practical about prevention and cleanup. We aren’t here to scare you. We’re here to make sure it doesn't happen to you, or at least that you know exactly what to do when it does.

There are stories here I'm still recovering from (ask me about the scorpions, or the "ladybugs" that aren't ladybugs). You're welcome.

Who This Episode Is For 

This one's for you if:

•        You just bought your first rig and didn't realize "my house has wheels" also means "my house has more ways in"

•        You're a full-timer who's fought an infestation in 300 square feet and lived to tell about it

•        You travel with kids or pets and break out in a sweat reading the warning labels on most pest sprays

•        You're a snowbird or seasonal RVer whose rig sits part of the year

•        You've parked in scorpion, ant, or wasp country and want to be ready next time

•        You hike in tick country and want to protect your people and your pups

And honestly? Even if none of those are you, my beetle-trafficking confession is worth the price of admission. Which is free. Our episodes are always free. 😊

What You'll Learn

Why Your RV Is an Easier Target Than a House

I'll be blunt: we're a matchbox. RVs have thinner walls, more seams, and more openings than a sticks-and-bricks — slide seals, utility hookups, water lines, underbelly vents, roof seams, awning roller tubes. Every one of those is a welcome mat if you let it be. The same pesty buggers you'd deal with in a house can get into a rig faster and make themselves at home quicker.

Start by Sealing — It's Free and It's the Most Important Step

Before you buy a single product, walk your rig and seal it up. This is the cheapest, most effective, chemical-free prevention there is. Here's the checklist we run:

•        Utility hookups, water lines, and slide seals

•        Underbelly vents and roof seams

•        Awning roller tubes and vent covers (prime real estate for wasps and carpenter bees)

•        Screen covers on exhaust outlets and refrigerator vents

•        Your AC unit — check it for nests before you fire it up after the rig's been sitting

One twist that genuinely surprised me: some sealants actually attract pests. Jennifer has stories about holes in roofs and sealant treated like tasty frosting. So check your seals regularly for bite and peck marks, not just leaks. (And if something's already gotten to your roof, that's exactly what our sponsor handles.)

My Family-Safe Arsenal

Because I refuse to fog my tiny home with chemicals my family and dog are breathing, I did a lot of research. Here's what earns a spot in our rig:

A non-negotiable safety note: not every essential oil is safe around animals. Some oils that are totally fine for humans are toxic to dogs, cats, and other pets. Always check before you diffuse or spray.

The Hacks We Tested and the Folklore We're Side-Eyeing

We get into the stuff people swear by: the dryer-sheets-and-Irish-Spring folk remedy, ultrasonic repellers, a genuinely clever use for WD-40 in your awning tube, and a botanical wasp-nest spray I dare you to pronounce. Some of it works. Some of it just makes your rig smell amazing. We tell you which is which.

When Something Gets In Anyway

Sealing isn't a force field. If a rodent moves in, you'll know it — droppings, gnaw marks, shredded nesting material, and a smell you won't forget. Get them out, then deep clean with an enzyme cleaner instead of bleach, which can damage RV surfaces.

And know your limits. Cockroaches in particular often need treatment you can't grab off a shelf, and if you ever reach for a fogger, please remember: an RV is not a house. Foggers and propane do not play nicely, and the "stay out for X hours" math is very different in a small space. There's one product that finally ended a brutal cockroach battle for Jennifer — she names it in the episode.

The Pesty Bugger That Won't Touch Your Rig — But Can Change Your Life

Ticks won't infest your camper, but one bite can lead to serious issues, including Alpha-Gal Syndrome, a red-meat allergy we've covered in depth. Keep a tick tool handy and check your kids and pets after every hike.

You Don't Have to Be Afraid of the Pesty Buggers

Here's where I've landed after years on the road: the bugs and the critters are just part of the deal. They were part of the deal in my sticks-and-bricks, and they're part of the deal now, only now I'm a little smaller, a little more sealed up, and a lot more prepared. I can't send a Ralph to everyone, but you can absolutely be your own Ralph.

Listen to this one before something shows up in your pantry — not after. Share it with the new RVer who's convinced their cat has it all handled. (Bless.)
