The Big Cheese Ultra Power Mega-Sonic Plug-In Twin-Speaker Ultrasonic Pest Repeller is a next generation ultrasonic unit that utilises megasonic technology, as created for The Big Cheese. The unit plugs directly into an electrical socket, so no additional purchases such as batteries are required in order to set the product up. There are no unsightly, long, trailing cables and the unit functions discreetly. Megasonic sound waves are emitted when the unit is switched on, creating an acoustically hostile environment for rodents, repelling them from the protected area without harm. The soundwaves operate at Sound Pressure Levels beyond the hearing of humans, cats and dogs. The unit should not be used around rodent pets such as hamsters or gerbils. The unit features a test button so you can ensure full operation. The 24/7 protection against rodents is completely poison-free and is a humane way to get rid of rats or mice without the need for traps.

Rodent Problems
No-one likes the thought of a mouse or rat in their home so spotting the signs early can help avoid larger infestations. Look out for: droppings, gnaw marks, scratches, dead or live rodents, smells, noises and unusual pet behaviour. Choose the control method from The Big Cheese that's right for you for immediate problems and prevent return by sealing gaps in walls, removing food sources and using repellent products from The Big Cheese.
Next-Generation Attack Wave Technology
Extensively tested against rodent pests, the next-generation attack waves within the Mega-Sonic range achieved positive test results in over 90% of treatment areas. Mega-sonic sound waves achieve a narrower and more focused sound wave pattern, holding their strength for longer and providing a more effective ultrasonic deterrent effect. Mega-Sonic repellers will effectively deter rodents from established habitats, as well as help prevent new infestations by mice and rats seeking feeding and breeding sites.
Poison-free Prevention
Also available in our welfare-friendly range: Anti Rodent Lacquer from The Big Cheese ULTRA POWER is a quick-dry surface treatment to deter rodent pests from biting and chewing, and is suitable for application to all hard surfaces including electric cabling and insulation. This powerful formula will provide up to 6 months protection against rodents, and is ideal for treating caravans and mobile homes in out-of-season periods. The unique trigger-handle ensures effective and accurate application both indoors and outdoors, making this product suitable for home and commercial use.

Does this have a cable?
No, the unit plugs directly into an electrical socket.


I plugged my repeller in but haven't noticed a difference?
It's important that steps are taken to help the effectiveness of the product such as clearing up leftover food or rubbish that rodents will be attracted to and blocking entryways. The repeller is a training device and as such may take up to 28 days to break the visiting habits of the rodents. You should not use baited traps or poison baits at the same time as this will counteract the repel action.


This product is a training device; what does that mean?
When it comes to repelling rodents, they will have built up habits that can take time to break. They know where their safe passageways are and need to learn, with the aid of the repeller, that these are no longer suitable. Therefore, it will take time for their usual routine to break. That's why you may not see an immediate decline in rodent activity.
