The Big Cheese Electronic Pest Repellers are designed to deter rodents – particularly mice and rats – from entering your home or shed. Utilizing a combination of ultrasonic sound waves and flashing LED lights, these devices create an unpleasant environment for pests without using harmful chemicals. They’re ideal for use in garages, sheds, basements, and other areas where rodent activity is a concern.
These repellers emit high-frequency sounds (typically 20kHz – 50kHz) that are irritating to rodents but generally inaudible to humans. The flashing LED lights add another layer of deterrence, mimicking the movement of predators and further startling pests. Operation is simple; just switch them on and place them strategically.
Each unit features adjustable sensitivity settings allowing you to tailor the response to your specific environment. They’re powered by readily available AA batteries (not included) and are designed for continuous operation. Please note that while effective, these devices are primarily a deterrent; complete eradication of a rodent infestation may require further measures.

FAQ
What types of pests do these repellers target?+
Primarily mice and rats. The ultrasonic frequencies and flashing lights are most effective against these common household rodents. They won’t deter larger pests like spiders or insects effectively.
How far does the ultrasonic sound travel?+
The range of the ultrasonic waves is approximately 1500-2000 square feet (140-185 square meters). However, this can vary depending on the construction materials and layout of your space.
Do I need multiple units to cover a large area?+
For larger areas, we recommend using multiple units spaced evenly apart to ensure comprehensive coverage. Ideally, place them in clusters for maximum effectiveness.

Yes, The Big Cheese Electronic Pest Repellers are designed to be safe for pets. The ultrasonic frequencies are generally considered harmless to animals, though some may find the flashing lights momentarily startling.
How often do I need to replace the batteries?+
Battery life depends on usage but typically lasts around 6-12 months. Monitor battery levels regularly and replace them as needed – alkaline batteries are recommended for optimal performance.
Can these repellers be used outdoors?+
While designed for indoor use, they can be deployed outdoors in sheltered areas like a shed or garage. Avoid prolonged exposure to direct sunlight or heavy rain.
Are the LED lights adjustable?+
Yes, each unit features an adjustable sensitivity setting that controls both the ultrasonic frequency and the flashing speed of the LED lights. This allows you to customize the repelling effect based on your environment.
What if the repellers aren't working after a few days?+
Ensure the unit is switched on and positioned correctly, away from potential sources of interference like speakers or other electronic devices. Try adjusting the sensitivity settings for optimal performance.
