How to detect listening device bugs in your home

Having an listening device bug installed in your home may seem like something that could never happen to you. It is possible, however, if your career requires you to protect company secrets. Bugs may also be used by someone who is interested in knowing your daily routine. Bugs are installed covertly, and are difficult to detect if you are not certain what to look for. One sure-fire way to find a listening bug is with the use of bug-detection equipment, which can be expensive. If you don't have access to such equipment, there are several other ways you can find out if a bug is planted in your home.

Listen carefully to your telephone. While using it, you may hear changes in volume or other odd noises. Hearing a "popping" sound may also signal a bug. If you hear noises coming from the phone even when it is hung up, this is indication of a listening device. If you regularly answer your phone, and hear no one, or hear a quick high-pitched beep, this may be another sign of a bug.

Look at the behaviour of your television. If bugs are present in the house, they tend to get in the way of television signals. Change the channels to see if there is any unusual static or interference. Channels that eavesdroppers frequently use include 2, 17, 13, 14, 50 through 60 and 66 through 68.

Use an AM/FM radio to sweep an area for listening bugs. Turn the radio to "FM," and change the station to one that is quiet and unused. Walk around the rooms in your house with the radio. If you hear a high-pitched squeal, it is a sign of a listening device in that room.

Look at your interior walls and ceilings. On the ceiling and walls, a small discolouration may indicate that a microphone was inserted there. Check behind electrical sockets, as well, if they appear to have been taken off. Look on the floor by the walls. If you see a powdery substance, this may be drywall debris that was left by someone inserting a device in the walls.

Look at the placement of your furniture and objects, especially in common bugging areas like an office or living room. If it appears that things have been moved, but nothing has been taken, you may be a victim of a listening bug.

Remove any suspicious gifts that you have been given from people that you do not know well. Electronic gifts, such as clocks, radios or pens can be outfitted with a bug. Occasionally, a business competitor may mail you such a "gift." Once it is in your house, they are able to listen to your activities.

Examine your surroundings. If you frequently see delivery trucks or a van parked outside your home with no one in it, these vehicles may be used as a listening post.

If repair men come to your house, and you did not call them, be wary. They may actually be there to install a bug in the house. Look carefully at their work when they finish the job to ensure that it was a real repair.
