Physical Inspection

The first thing you can do to find these bugs is physically inspect your surroundings. You can check possible hiding spots for these listening devices in your home. Your physical inspection can include the following steps.

  • Look for strong wifi: You can look for the availability of a strong unrecognized wifi network in your area. These unknown networks can be the network of a listening device to transfer your data to the hacker.

  • Use a dark environment: The listening device placed in your house may have a blinking red or small white light. You can turn off lights in your suspected room or area to check if you notice any such small lights around you.
  • Check every possible hiding spot: You can also physically check furniture, walls, couches, electricity outlets, plants, or any other spot where it is possible to hide such devices. This can help you spot any change in your environment and hidden listening devices.

Radio Frequency Signal Detector

You can use a Radio Frequency (RF) Detector to find hidden listening devices in your house. RF detector captures any device in your surroundings that is emitting radio waves. It can also detect the waves emitted by hidden listening devices to transfer your data.

You need to turn off other wireless devices for the RF detector to work properly. Now turn on the detector and slowly move it in your area such as walls, ceilings, and floors. This device can detect listening devices in your surroundings and indicate to you a small beeping sound.

Non-Linear Junction Detector

You can also use a Non-linear junction detector (NLJD) to detect any hidden device in your surroundings. It allows you to detect hidden listening devices under furniture or within objects by emitting High-frequency signals.

These signals reflect back from non-linear junctions around you and your NLJD receiver detects the reflected signals. It then shows you the location of hidden devices in your surroundings. You need to carefully check the results of this receiver because it can also detect safe objects such as nails and other items from your surroundings.

Sweep out Unfamiliar Audio

You need to investigate audio differences in your house to detect hidden listening devices using different equipment and techniques. Now wait for silence in your surroundings and turn off all electrical appliances to focus properly. You need to check if you hear any unknown buzzing or clicking sound as it can be caused by listening devices.

Check if there is any high-pitched noise coming from your electrical devices for no reason. You can also notice interference of noise when talking over a phone call near a hearing device. You can try tapping on the walls and floors of your house to notice dense areas where hidden listening devices can be placed.
