Battery mole repeller Greenmill GR5112 — ultrasonic garden pest deterrent, battery-powered

The Battery mole repeller Greenmill GR5112 — ultrasonic garden pest deterrent, battery-powered is a portable device designed to discourage moles and other burrowing animals from lawns, flowerbeds and small garden plots. The unit generates intermittent ultrasonic pulses combined with ground vibrations to create an environment that is uncomfortable for tunnelling pests while remaining safe for plants, people and pets. Its battery-powered design allows placement without wiring and makes it suitable for seasonal or temporary use in home gardens, allotments and park greens.

Advantages

The repeller operates on batteries, enabling flexible installation anywhere in the garden without the need for mains power. Ultrasonic pulses and subsonic vibrations work together to target burrowing animals, reducing the likelihood of tunnelling and root damage. The compact and weather-resistant housing is intended for outdoor conditions, and the straightforward push-in installation makes it possible to relocate the unit quickly as needs change.

Suitable for

• Home lawns and ornamental flowerbeds
• Allotments and vegetable plots where mechanical or chemical methods are undesirable
• Small public greens and park edges
• Temporary protection of newly planted areas and seedbeds

Key specifications

• Power source: battery-operated for cordless placement
• Output: ultrasonic pulses combined with ground vibration
• Housing: compact, weather-resistant construction for outdoor use
• Installation: stake-style push-in mount for soil insertion
• Coverage: designed for localised protection around the unit (coverage varies with soil type and pest pressure)

How to use

Choose a location in the affected area and press the stake into the soil so the vibration unit is in firm contact with the ground. Insert the batteries according to the manufacturer's polarity markings and switch the device on. For best results, place the unit near active tunnels or in a central position within the area to be protected. Periodically check battery condition and reposition the repeller if tunnelling continues in other parts of the garden.

Usage recommendations

Position multiple units at intervals for larger areas, and avoid placing the device on excessively rocky or waterlogged soil where ground vibration transmission will be reduced. Combine mechanical soil management and habitat modification with the repeller to improve overall pest control effectiveness.
