Repel pests naturally without killing them. No need to clean up dead bugs and rodents. Pest repellers create an uncomfortable environment for pests, so they usually only leave after a few weeks of use.Ultrasonic repellers emit ultrasonic waves that are very uncomfortable for squirrels, mice, rats, insects, etc., causing them to leave the room. This item is for indoor use only.While these devices are designed to keep bugs and pests at bay, it can also be sensitive to high-frequency sound-sensitive rodents such as mice, squirrels, rats, and small animals.Because insects, rodents, bugs, and other pests are repelled, you don& 39;t have to worry about cleaning up and using spray pests, they need to be swept away, unlike where chemical repellents are used.Careland Pest Control consists of sensors and dual speakers that emit high shock pressure waves and 25KHz-60KHz ultrasonic sound to effectively control squirrels, rats, mice and most other common noses."</p>
