25-55kHz 🚗🧨 Ultrasonic Rodent Repellent — because engines shouldn’t come with surprise guests
Honestly, nothing ruins a calm morning like opening the hood and finding evidence of tiny roommates. LeafZap is designed for people who want a cordless-friendly, under-hood deterrent approach that also works in spaces like garages or attics.
LeafZap is a battery-powered ultrasonic rodent repellent for car engines that combines upgraded 25–55kHz ultrasonic waves with 6 white LED strobe lights. The biggest appeal is the “dual mode” concept—ultrasonic deterrence plus visual strobe activity—so it’s not just one tactic you’re relying on.
It also leans into convenience. Once you power it on, it automatically cycles active defense and standby. There’s a built-in vibration sensor that switches to standby when your engine starts, then reactivates after you park—so you’re not constantly remembering to toggle anything.
And if you’re thinking “cool, but can it do more than cars?”—yes. You can run it with 4 AA batteries for cordless use, connect a DC cable for under-hood power, or plug into a USB adapter for indoor use in places like a garage, kitchen, attic, or warehouse.
