The Big Cheese Mega-Sonic Twin-Speaker Ultrasonic Pest Repeller


Introducing the Mega-Sonic Twin-Speaker Ultrasonic Pest Repeller from The Big Cheese - the ultimate solution to rodent infestations in living spaces and outbuildings.

The Mega-Sonic Twin-Speaker Ultrasonic Pest Repeller boasts next-generation ultrasonic attack-wave technology, which guarantees a protected zone of over 60m² of unobstructed space. Plus, with its wide-angle output, it provides whole-room protection - making it twice as powerful as single-speaker repellers.

Capable of being used both as a curative treatment to dispel rodents from infested areas and as a follow-up preventative treatment after using traditional poison baits or traps. And the best part? It's poison-free rodent control for the home - 24/7 protection without any harmful chemicals.

With a 1.65 metre power cable, it's easy to position wherever you need it. And because it is completely inaudible to humans, it is safe to use around cats and dogs. However, it should not be used near rodent pets such as guinea pigs, hamsters, and rabbits.

Say goodbye to pesky rodents for good with The Big Cheese Mega-Sonic Twin-Speaker Ultrasonic Pest Repeller.
