One Gel. Every Place Mice Cause Damage.

Rodents read the world through smell. Concentrated peppermint oil overwhelms the scent receptors mice depend on to navigate, find food, and follow the pheromone trails that mark a space as safe — so a treated area reads as unreadable, and unreadable means dangerous. The animal moves on before it ever chews a wire or builds a nest.

The catch with any scent barrier is persistence, and that's the problem gel solves. A liquid spray dries and dissipates in weeks. RepelGel's concentrated formula binds the peppermint oil in a clear, non-corrosive gel matrix that releases vapor slowly — which means one careful application in fall can still be working when you uncover the vehicle in spring. It clings to vertical metal, plastic, and wood, doesn't drip, doesn't stain, and doesn't harm paint, rubber, or wiring insulation.

Vehicle underbody (cars, trucks, motorcycles). Mice climb in through wheel wells and along frame rails, then settle in engine bays where modern soy-based wire insulation is genuinely edible to them. Run a bead of gel along both frame rails, around each wheel well, across the engine-bay perimeter, and at every cable or hose pass-through into the cabin. A 12 oz tube covers a full-size vehicle. Duration: about 60 days in open storage, longer under a car cover. Refresh once mid-winter for stored classics.

Attics and crawl spaces. Set open gel placements every 8–10 feet along the perimeter, with extra placements at eave gaps, vent penetrations, and anywhere you've found droppings. Enclosed, low-airflow spaces are gel's home turf: expect up to 90 days per placement. Treat in early fall, before the indoor migration starts.

Camper, RV, and boat storage. Place gel containers in cabinets, under seats and berths, in the engine compartment, and near shore-power and plumbing pass-throughs — one placement per 100 square feet of interior. Add a bead along the underbody and tongue/jack points. Close it up and the mint vapor concentrates exactly where mice would nest.

Farm and stored equipment. Combines, tractors, skid steers, and seasonal implements are the most expensive victims of rodent wiring damage. Gel the cab perimeter, battery box, harness runs, and the engine bay before parking equipment for the season. For machine sheds, add placements along walls at 10-foot intervals. Check placements every 60 days; refresh when the gel has visibly shrunk or the mint scent is gone at arm's length.
