Pest repelling aid , here two indicator of light , green light indicate for made up of ultrasonic sound , and the second red light indicate electromagnetic waves , those two lights are effective for rat , cockroaches , ant , mosquito and any other insects . This product do effective job , no need to fill with liquid . I buy this because it has no pollution, natural sources . First I don't believe about this product but when I used ,I realised it's activity.
Even after turning this on, after a full 14 day use, I can say that this is useless and doesn’t do what it advertises. The mice still come out for a stroll just 5-7 feet away from this device’s direct line of sight with no obstacles. I don’t think there is a sure shot device in the market that can get rid (not kill) of mice.
