Non-repeating sequence of sonic waves is used for frightening rodents and moles. It excludes the possibility of habituation that often emerges while using cheap repellers made in China. As the signals change, animals can’t easily adapt to them and will leave inhabitation finally.

Patented pattern of sound vibration allows to exclude entirely the sound decay. As a result the zones where rodents can still live will not emerge. It also allows to use a number of repellers in a room to expand the effective range of repelling.

• Protection range: up to 500 m2 (5,800 sq. ft);
• Doesn’t lead to the pests’ habituation effect;
• Safe for humans and pets;
• Proven efficiency against mice, rats, moles, hamsters, soricids;
• Can be used within industrial premises.

High emission power

The product’s protection range is up to 500 m2. Researches made by our company have proven that it’s impossible to further increase the emission power, because then it will impact humans. Consequently we can confirm that the maximum protection range that’s possible using this repelling method has been achieved.

Stand-alone use 

The product is intended to be used stand-alone, within the areas that are not equipped with 220V mains (in basements and cellars, outdoors, etc.). GRAD A-500 sonic mouse, rat and mole repeller can operate from conventional or rechargeable batteries, or from 220 V mains by power adapter. It can be delivered with a car adapter (optionally) for the stand-alone operating from a standard car battery.

GRAD A-500 sonic mouse, rat and mole repeller can be used both above ground (for protection from rats, mice, hamsters) and underground (for protection from moles and soricids). While using underground the device should be hermetically put into PVC film and then moved down to the mole’s hole. The efficiency of this method, as well as the fact that moles go more than 100 meters away due to the product’s operating, have been proven by many experiments conducted by our personnel.

GRAD A-500 sonic mouse, rat and mole repeller was tested for 3 years under the town and village conditions.

Area of use

• Indoors (if there are no people living near). The product can be used in animal husbandries and chicken farms, vegetable stores and granaries, warehouses, factories, hotels, restaurants, shops, holiday camps, etc. Besides it can be used to protect tunnels, lift shafts, hangars, underground utility systems and subsurface telecommunication lines. In everyday life it helps to protect summer cottages, houses, flats, cellars and basements, gardens and kitchen gardens.

• Installation within indoor spaces opening to the outdoors. If it’s necessary to protect open areas (gardens, kitchen gardens, fields, plantations, vineyards), the device can be installed near a window indoors, directed to the open area.

• Underground installation. To ensure protection from mice, rats, moles, hamsters, soricids the device should be hermetically put into PVC film , then moved 10 cm down and directed to the mole’s hole.
