The MouseBlocker is designed for direct 12V installation under the hood so it runs off the vehicle battery, tolerates extreme temperatures and moisture, and operates continuously without replacing batteries. It aims to make the engine area uncomfortable for rodents by emitting a focused, high-decibel ultrasonic signal chosen to mimic harsh mechanical noises that pests avoid.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the MouseBlocker prevent rodents from nesting under my hood?\u003c\/h3\u003e\n\u003cp\u003eThe unit produces a concentrated ultrasonic frequency at about 85 decibels selected to be unpleasant to mice and similar pests.
