Review on 🐭 12V Ultrasonic Under Hood Mouse and Rodent Deterrent for Vehicles - MouseBlocker by David Elam

I had to remove mouse nests from my tractor mower almost every week which is a two hour job. Once the motor head was overheated and warped by a mouse nest. expensive repairs. I bought this 12v mouse blocker and attached alligator clips to connect it to the tractor battery. I haven't seen any mouse trails since installing it in July. It uses very little power so battery drain is not noticeable. Maybe it's a little expensive, but it works! It's easier on my engine and saves me having to open the hood to mow the lawn every week.
