Plug-In Ultrasonic Pest Repeller

The Revolmax RX-78 is a 6-pack of indoor plug-in units designed for homeowners who want chemical-free pest control across multiple rooms. Each device emits AI-tuned ultrasonic waves that target the nervous, auditory and olfactory systems of rodents, bats and common insects. The compact form factor fits any standard outlet without blocking adjacent sockets, making it suited for kitchens, bedrooms, garages, attics, basements, offices and RVs. It is not for buyers who need outdoor-rated hardware or professional extermination-grade equipment.

Silent 13W Operation With Night Light

Each unit draws 13 W and runs continuously without audible noise for people or pets, thanks to frequencies that cycle between 20 kHz and 65 kHz. A built-in soft night light adds low-level illumination for hallways or nurseries while the repeller operates 24/7. There are no fans, moving parts or chemical emissions, so thermal output remains negligible and daily routine stays undisturbed. It is not for users who expect adjustable power settings or app-based monitoring.

Six Units Extend Coverage To 1600 Sq Ft Each

The pack provides six T-24 devices, each rated for up to 1600 sq ft in open areas, allowing simultaneous placement throughout a property for broader protection. Manufacturer guidance notes an initial activity uptick in the first days, noticeable change around 12 weeks and full effect by 34 weeks of uninterrupted use. No traps, baits or refills are required, and US-based support is available. It is not for situations demanding instant elimination or single-room spot treatment only.

Questions about this item

How do I install the RX-78 unit and what is the common mistake to avoid?

Plug each unit directly into a standard wall outlet; the common mistake is placing furniture or curtains in front of the device, which blocks the ultrasonic waves from covering the full 1600 sq ft area.

What maintenance or replacement will the RX-78 need over time?

The units are designed for continuous 24/7 operation with no replaceable parts, cartridges or filters; simply keep the grille clear of dust and leave them plugged in for the full 34-week cycle.

What is the first limit that appears under sustained use of the RX-78?

Ultrasonic waves cannot pass through walls or solid objects, so each unit only protects the single room it is plugged into, requiring additional units for adjacent spaces.
