Buying advice

When choosing an automotive pest repellent, consider the type of pest (rodents, insects) and the area you need to protect (engine bay, interior, wiring). Ultrasonic devices are good for continuous broad coverage but may not deter all pests. Natural sprays are safe but require regular reapplication. Tape-style repellents are ideal for protecting wires. Always check product reviews for effectiveness in real automotive conditions.
