Rodents – particularly mice and rats – are one of the most common problematic pests. These unwanted creatures live wherever humans live, especially in urban areas. Mice and rats have developed very sensitive hearing to ultrasonic sound, and have a highly developed sense of smell. Designed to attack these very senses, Prompt rodent control products are scientifically proven effective in keeping mice and rats away from treated areas. Ultrasonic devices can be used as pest squirrel repellents as well.
