They usually make use of a dependable power supply. For this, search for physical wires that are not leading anywhere.

Sometimes, the bug is also made to steal power from other devices like a USB cord. Take your chances and begin your search and seizure mission by checking all possibilities.

Search In Peace

To find a hidden listening device, your house must be completely still and free from any noise. The best time to search is when the house is empty, and there are no other noises like traffic noise or any other appliance noise.

Once everything is muted, look around carefully to listen to some buzzing or beeping sound. Track down the source when you hear it.

Check Electric Switch Plates

Listening devices are best installed behind electric switch plates. For this, check each of your wall sockets and switch plates carefully to find out if any of them has been recently disturbed or coming out loose.

If you find any such wall socket or switch plate, unscrew the plate after turning off the power and see if you could find anything unusual there.

Check The Flooring

If you have wooden flooring or baseboards installed, checking them is another way to find installed bugs. Carefully look for any bumps in the flooring or any sign that seems inappropriate.

Check Every Other Furniture

Bugs or microphones are even placed or stuck beneath the furniture like sofas, tables, and chairs. You need to thoroughly search every piece of furniture in your house by running your hands underside them. Also, search for any holes in the upholstery.
