A pack of 3 mini 500 units for extra ultrasound coverage in areas such as lofts, garages, basements etc. This is the entry level ultrasonic pest repeller, effective against mice and crawling insects. The 500 uses fluctuating ultrasonic waves to cause auditory stress to pests.
- Direct plug-in design - use almost anywhere in the home.
- Covers 1 room at least 500 sq. ft. Ultrasound does not penetrate walls or other sollid objects, and is best positioned with an unobstructed 'view' of the target area.
- Fluctuating ultrasonic waves cause auditory stress to mice, rats and most crawling insects, which disrupts their normal behaviour patterns and makes it uncomfortable for them to stay in the same room as the 500.
- Safe and effective - no chemicals or traps.
- Will not affect humans, cats, dogs, fish or birds.
