Bug Sweeps – Eavesdropping Detection – Technical Surveillance Counter-Measures

In the last decade, bug sweeps are now one of our most requested services. With the rise in technology becoming more affordable, compact, and adaptable, it is more accessible for those with nefarious intents to eavesdrop on a victim to steal valuable intelligence. Common situations that increase susceptibility to being bugged:


  • Involved in a lawsuit
  • Have plans to or have recently downsized
  • In a competitive industry that relies on insider knowledge (marketing, fashion, automotive, product development, medical, technology, advertising, etc.)
  • Involved in government affairs or politics

Personal affairs:

  • Filing or in the middle of a divorce
  • Involved in a custody battle (it is common for the children to have devices hidden in their things or on them during visits)
  • In the process of getting married
  • Filed an insurance claim
  • Is or previously was in a position of power or influence, in business or politics
  • Is a minister or religious leader
  • Suspects the person eavesdropping is someone close to them who work in law enforcement, security, or the judicial system.

People have found out about personal matters or confidential business secrets, or just seem to know too much about their activities.

This is the most telling sign that they may be bugged: The client has noticed people they have never disclosed information to know about their personal and business affairs. If it is a business, there are signs that a competitor or vendor has obtained the business’ internal information.

In the Home and Office

Evidence of a break-in, but nothing was stolen

Even if there is no overt evidence, the client may notice that something “seems off,” such as furniture or objects slightly moved, closets and drawers are rummaged through, or dusty areas are disturbed. Additionally, a client may note that suddenly a new object was added to the home after the break-in, such as clocks, signage, picture frames, tissue boxes, lamps, and radios.

Wall fixtures have shifted slightly

Some of the most popular hidden surveillance devices are designed to go inside or behind electrical outlets, light switches, smoke alarms, and lighting. Hidden camera lenses can be as small as the head of a screw, making them ideal to conceal in common wall fixtures.

A strange vehicle parked near the home or office frequently with no one inside

Devices that transmit the recordings via Wi-Fi or radio frequency may require the eavesdropper be stationed nearby. Service or delivery trucks are commonly used: if you see the same or similar vehicle more than three times, there may be an eavesdropper. Vehicles with black or tinted windows allow the perpetrator to conceal themselves in the back of the vehicle to monitor the devices. Ladders or pipe racks on a vehicle can help conceal an antenna or beacon.

Interference in landlines, radios, or televisions

The client has noticed that their radio, landline, or television are acting “weird.” This includes increased interference, a solid faint tone or high-pitched squeal on the phone, (note that beeping or high-pitched noises could just be a result of a fax machine dialing the wrong number) or their radio loses signal in areas it has never lost signal before.

Common objects have a small hole or reflective surface

Many spy stores sell popular, common home and office products such as lamps, clocks, tissue boxes, plant boxes, or exit signs, with a camera or microphone pre-installed, containing a small hole or reflective spot to hold the camera lens. A client has noticed that these products “just appeared” or these things have changed slightly in appearance.

In the Office

Ceiling tiles appear disturbed, discolored, or damaged, or have ceiling dust on the floor

A common installation location for hidden listening devices is inside the ceiling tiles: Their accessibility makes them a prime target. The client may have noticed that tiles have shifted, are not properly set in the frame, or were recently damaged. However, note any recent maintenance issues in the building: These signs could be just a result of a pipe leaking or new construction.

Bump in the vinyl baseboard

A small bump or deformity in the vinyl baseboard along the floor is a sign that someone hid and adhered a wire or microphone behind the baseboard. The vinyl-style baseboards are more popular in offices than homes.

The client recently received gifts from vendors

If the client suspects that a competitor or vendor is spying on them, a common tactic is to place listening bugs inside “gifts,” such as pens, clocks, briefcases, adaptors, etc. Ask the client if any gifts were given to them, and what they were specifically.

In Their Vehicle

Their car appears broken into, but nothing was taken

Something inside the vehicle seems “off”, but nothing was stolen. The client may have noticed that the seating moved, (even though they are the primary driver and have not lent the car to anyone recently) the car rummaged through, or there are new items in the vehicle. This may have occurred multiple times, as the eavesdropper may need to retrieve the device to download the data or recharge the battery.

Their car is taking longer to start

Some tracking and eavesdropping devices are connected to the car battery, using the power source when the engine is off. While it may not completely drain the battery, it can cause the car to stutter a bit as the remaining power tries to start the engine. This is not as common now as devices have moved more towards using internal batteries, going into an “idle” mode when movement or sound is not detected to conserve power.

Electronics in the car are behaving erratically

The electronics in the car, including the radio and displays, are acting strange, which could result from interference from a covert surveillance device.

Others seem to know the client’s whereabouts

The client has noticed that others seem to know too much about their travels and driving habits. GPS tracking devices can be attached to a car with something as simple and discreet as a strong magnet. Common areas include under the engine bay, rear bumper, inside the dashboard, and behind the wheel well.

Client suspects they are followed while driving

If there is a hidden microphone or camera in the car, the suspect may need to stay within a certain range of the device to acquire the recordings. The client has noticed that the same vehicle was following behind them or has frequently parked near their car.
