Don’t forget to inspect wires, USB cables, and extensions because a listening device will require a power supply, and its batteries do not last long. There is a high chance that you will find the listening device connected in some way or another.

Find a listening device with a phone

Your smartphone can also be used to scan for a listening device. All you need to do is make a call and let the receiver know why the call is made so that the other person does not drop the call in between.

If there will be a bugging device, it will interfere with the signal, and you will hear a distortion while you are on the phone. Roam around the place while you are on a call and notice if there comes a distortion.

Check your Wi-Fi network
