Ultrasonic Repeller Greenmill GR5116 — Pest Deterrent Device, Model GR5116

Greenmill GR5116 is an ultrasonic repeller designed to reduce the presence of common household pests by emitting high-frequency sound waves. The device operates without chemicals or physical traps and is intended for indoor use in spaces such as homes, garages and storage areas. Quiet to human ears, the unit targets rodents and certain insects to create an environment that discourages habitation and activity.

Advantages

The Ultrasonic Repeller Greenmill GR5116 offers a non-toxic method for deterring pests and requires no ongoing consumables or bait. Its plug-in design allows continuous operation with minimal user intervention, and the absence of mechanical parts reduces maintenance needs. Because it uses ultrasonic frequencies rather than chemicals, the device can be used as a complementary measure alongside sanitation and sealing methods to support integrated pest management strategies.

Suitable for

• Indoor rooms in residential homes
• Garages and workshops
• Pantries and storage closets
• Basements and utility rooms

Key specifications

• Operation: ultrasonic emission for pest deterrence
• Intended environment: indoor use
• Target pests: rodents and certain insects
• Power: mains powered plug-in unit (continuous operation)
• Maintenance: no consumables, no physical traps

How to use

Place the Greenmill GR5116 in a position within the affected room where the device is unobstructed by furniture and faces the open area for optimal sound dispersion. Plug the unit into a standard wall outlet and leave it powered on for continuous operation. For larger or partitioned spaces, use multiple units placed in separate zones to improve coverage. Combine the device with standard hygiene and sealing practices—such as removing food sources and closing entry points—to increase overall effectiveness.

Usage recommendations

Position the repeller at a height of approximately 30–120 cm above the floor and avoid placing it behind curtains or inside cabinets. Allow several days to assess changes in pest activity and monitor results over time; ultrasonic devices work best as part of a broader pest-control approach rather than as a sole solution.
