Can You Really DIY a Bug Sweep?

When people suspect their home, office, or vehicle might be “bugged,” their first instinct is often to search online for a do-it-yourself solution.
For less than $100, you can find dozens of “bug detector” devices on Amazon that promise to locate hidden cameras or GPS trackers.
Unfortunately, these devices rarely detect what truly matters — and can give users a false sense of security that everything is fine when it isn’t.
Why DIY Bug Sweeps Fail
A professional bug sweep involves far more than waving a handheld scanner around a room.
Licensed investigators use multi-frequency RF detectors, non-linear junction detectors (NLJDs), spectrum analyzers, and other tools calibrated for government and corporate security work.
In a real sweep, every outlet, light fixture, and circuit box must be tested — often requiring covers to be removed and lines to be traced.
Wi-Fi and electrical power are shut down during testing to prevent interference. Even a running modem can produce enough signal noise to hide a small transmitter.
The Legal and Safety Risks
An untrained person opening electrical outlets or disconnecting wiring could easily damage property — or worse, create a safety hazard.
And if you accidentally tamper with a device placed as part of an active investigation, you could unintentionally obstruct evidence.
When to Call a Professional
