When you first install PEST CONTROLLER turn the knob fully to the left or to the right. Each month or so, twist the knob just a bit in the opposite direction.
Depressing the test button before and after the adjustment lets you hear the slight difference in sweep rate. You will begin to notice the effects of PEST CONTROLLER in a few days.
There will be an absence of rodent activity. Perhaps you will notice and increase in insect activity during this time due to the ultrasonic sound waves driving these pests from hiding. In a short while they'll be gone also.
While the pests are being driven away, they are undoubtedly leaving their eggs and leaves behind which are not affected by the ultrasonic sound waves.
Incubation will continue and they'll hatch usually. At this point, however PEST CONTROLLER "S" ultrasonic output will begin to attack these hatching's auditory and nervous systems, driving this new generation away. In 4 to 6 weeks the infestation should be over and you'll be free of pests. Leave PEST CONTROLLER plugged in for year round, day and night pest control.
