Using the device outdoors, it is more directional with the sound so place the device with the speakers pointing at the infested area, similar to pointing a flashlight where you need it. On the inside, the sound does bounce off of hard surfaces, such as walls, ceilings, and even furniture. Try not to obstruct the front of the device as we do not want it muffled but filling up the area with sound. Again, similar to a flashlight, obstructed you can’t see much, but unobstructed even a small light can fill a room.

As long as the device is not blocked by any obstacles, you can really place it anywhere you have an infestation. Try not to place the device behind any furniture, curtains, or any other obstruction that can muffle the sound. When the device is outside, place the T3-R so the speakers are facing the infested area as it does need a line of sight as there is no four walls and a ceiling for the sound to bounce off.

This can be a fairly broad question, each situation is different and in most of these scenarios, rodents from different areas react in their own way. We do suggest leaving the device running continuously until all entrance points are sealed to keep them out. Otherwise, they will come back to a familiar area and start nesting again. However, if you do know where the entrance point from the outside is and you have the device in the kitchen, you can move the device to the outside near that entrance point and it will help keep them out.

The T3-R is water resistant but not quite waterproof, so it can be splashed by water or a light rain, but should not sit in a puddle where water can seep inside.

I’ve spoken with many customers who’ve reported this kind of activity. What’s usually happening is that the sound is making the critter panic and be less cautious than normal while it tries to escape the sound or from your house/garage/kitchen/…

We hear this often. Apparently, car makers have started using vegetable matter instead of plastic for wire insulation and rodents like eating this wiring out of cars. Also, if the rodents can get into an engine, they will build nests. In this situation, place this device underneath the vehicle with the speakers facing down the length so as much area under the car and the wheel wells are covered by the ultrasonic sound.

The device is designed to be above the average cat or dog’s hearing. It does sweep through a wide range of sounds, and occasionally a dog or cat might hear it when it sweeps down into the lowest register. This device is safety tested to ensure that the decibel rating is not loud enough to damage a human or pet’s hearing. For your pet, it’s the equivalent of standing in a parking lot with a car alarm going off nearby – annoying but not harmful.

When rodents are getting in your home, place this device on the inside to help chase them out, then move to the storage area and after that place it underneath the trailer with the speakers facing down the length, to keep them out from there.
