No. Most independent testing shows electronic pest control devices, including ultrasonic plug-ins and electromagnetic repellers, do not reliably deter common household pests. Professional treatment continues to deliver the only consistent results for homes across Tweed Heads, Banora Point and the wider NSW Northern Rivers.
How These Devices Claim to Work
Ultrasonic units produce high-frequency sound, usually above 20 kHz, which manufacturers argue irritates pests into leaving. Electromagnetic models claim to disturb pests through the existing wiring in your walls.
Real-world results tell a different story. Sound does not travel well through walls, timber or soft furnishings, and pests quickly ignore any signal they can detect once food or shelter is nearby. Controlled testing has shown rodents continue to nest, feed and breed in rooms with active devices running around the clock.
Cockroaches, ants and spiders respond even less. Their hearing and nervous systems simply do not react to the frequencies these gadgets produce, which is why Australian households relying on plug-ins alone often still face active cockroach problems and ant trails during the warmer months.

What Actually Works
Integrated pest management delivers the consistent results a home actually needs. This combines inspection, habitat reduction, targeted baiting and, where required, safe chemical treatment. Sealing entry points, clearing food sources and controlling moisture form the backbone of any lasting outcome.
For persistent or larger infestations, professional help is the fastest route to a clean home. Licensed technicians identify the species, locate nesting areas, and apply products that are regulated and safe around children and pets.
