You can’t install this under the car’s hood. You will have to remember to remove it each time you start the vehicle.Also, it can’t be used in temperature over 80°. In Nevada that is a problem!!!

Put into my car’s engine compartment as rats had started to nest inside the engine compartment. Put one in all four cars, and so far so good at repelling vermin.
