Been dealing with mice in my walls for two winters straight. Third winter with Calorvi — nothing. The walls are finally quiet.

See why homeowners, RV owners, and farmers trust Calorvi
"First time in months I didn’t check the floor when I woke up."
I’d tried the cotton balls, the plug-in ultrasonic thing, even a pest service that came twice. Still heard scratching. Put Calorvi pouches under the sink and behind the stove — two weeks later, nothing. No noise, no droppings. I actually slept through the night.
"Opened it in April and there was nothing waiting for me."
Left my camper in a wooded lot all winter. I’d had a nest situation the year before — shredded toilet paper, chewed wiring, the works. Put Calorvi pouches in every bay before I locked it up in November. Spring opener was the first one in three years I wasn’t dreading.
"Kept the feed room clean without putting my chickens at risk."
I’ve got chickens, two dogs, and a pregnant goat. Poison was never an option. Tried peppermint spray — mice didn’t care. Put Calorvi in the corners of the feed room and inside the cab of my tractor. Haven’t lost a bag of feed since. Nothing to check, nothing to dispose of.
The signal that tells a mouse “something’s wrong here.” Peppermint creates an immediate aversion response in enclosed spaces — but only when it’s concentrated, sealed, and paired with other oils that reinforce the message. Alone, it fades in days. Here, it anchors the blend.
The layer that changes the scent profile entirely. Mice rely on familiar scent pathways to navigate and feel safe. Cinnamon disrupts that familiarity — it doesn’t smell like food, shelter, or anything a mouse wants to move toward.
The longest-lasting note in the blend. Where peppermint can fade fast in open air, lemongrass holds its presence longer — extending the effective window of the pouch and keeping the environment actively unwelcoming between replacements.
The sharpest signal in the formula. Clove is naturally high in eugenol — one of the most potent aromatic compounds in botanical pest deterrence. It’s the reinforcement layer that makes the blend harder to filter out and move past.
Here’s what changes when Calorvi is in place.
Most repellents ask you to trust them. Calorvi shows you exactly what to expect.
No more lying awake listening.
The scratching that keeps you up at 2am happens in the dark enclosed spaces behind your walls and under your cabinets. That’s exactly where Calorvi works. No noise doesn’t mean no mice ever — it means they’re not finding a reason to stay.
Open it in spring and find nothing.
RV bays, equipment cabs, feed rooms, utility closets — the spaces that sit unattended for weeks are where the damage happens. Calorvi is built for exactly those spaces, not an open room where scent disappears in hours
No traps. No carcasses. Ever.
No bait to handle, no trap to reset, nothing dead to deal with. Place a pouch, mark the sticker, replace it when the date comes. That’s the entire interaction.
Know it’s working and when to replace it.
No guessing, no sniffing the pouch to see if it’s still active. Every Calorvi pouch comes with a replacement date sticker. Mark it when you open it. The rest takes care of itself.
Place it once and here’s what the next few weeks look like — no droppings to find, no traps to check, no guessing whether it’s working. Here’s what customers tell us they notice:

Frequently Asked Questions
Not if it’s placed correctly.
Most pouches fail for the same three reasons: open air kills the scent in days, single-note peppermint is easy to filter out, and wrong placement means mice never encounter it at all.
Calorvi uses four oils — not one — in a sealed slow-release pouch built for enclosed spaces where the scent concentrates. That’s the difference.
Up to 90 days in enclosed spaces.
The same scent that disappears off an open countertop in days holds its concentration for months inside a cabinet, storage bay, or utility area.
Keep it enclosed. That’s the entire protocol.
A space that smells actively unwelcoming doesn’t get that kind of attention.
Mice chew through things they want to reach. If your space is doing its job, they’re not sticking around long enough to investigate the pouch.
Yes. 60 days, no questions, no fine print.
Try it. If you don’t see a difference in treated areas, contact us for a full refund. No unused-condition requirement. No return shipping. The headline means what it says.
Yes — when placed correctly.
Keep pouches inside closed cabinets, storage bays, and feed room corners. Out of direct reach of animals and children.
For properties with poultry, goats, or cattle — place inside closed storage areas only. If you have specific concerns, check with your vet on the individual oils: peppermint, cinnamon, lemongrass, and clove.
Calorvi isn’t your first call — a professional wildlife removal service is.
Get the existing population removed and entry points sealed. Then use Calorvi to make sure they don’t come back.
