Buying advice

Consider the environment: if parking outdoors, a weatherproof ultrasonic device is ideal; for indoor storage, plug-in repellents may work. Check the vehicle area where rats enter - hood, cabin, or tires - and choose accordingly. Reapplication of sprays or granules may be necessary after rain. For best results, combine a physical barrier (like an ultrasonic device) with a scent deterrent.
