Explain:Because this product is physically driven, it usually needs to be used continuously for 2-4 weeks to show its effect. Rats, mosquitoes, cockroaches, etc. will be significantly reduced, and they will escape because they cannot withstand the ultrasonic and infrasound. In areas where the rats are less harmful, a more obvious effect can be seen within one week. In some cases, there will be rats and cockroaches that are more active/running around in the two week. This is a normal reflection. This is because mice, mosquitoes, cockroaches receive ultrasonic waves from this product, and electromagnetic waves interfere with and stimulate. A physiological reaction to nervous disorder and irritability! Package Included:1 x Zapper
