Dealing with annoying pests is not a lot of fun. A lot of people use chemicals to handle that problem but that approach has many drawbacks. The RADARCAN Ultrasonic Pet Repeller is a plug-in device that uses high-frequency sound waves to get rid of roaches, mice, and ants. It starts working after a couple of weeks.
The RADARCAN R-200 has two tweeters to cover up to 2691 sq.ft of space for ants and about 430.5 sq.ft for mosquitoes. It uses MAGNETICAE technology to alter magnetic fields and get rid of ants.
