Q: I have a large open-concept living room that’s around 1,000 square feet—will one of these ultrasonic repellers be enough to cover the whole space, or do I need to add more units?
A: A single unit can cover up to 1,200 square meters at maximum, but solid walls or furniture will weaken the ultrasonic waves. For your 1,000 sq ft open-concept living room, one unit should work just fine if you plug it in a central spot. If you notice pests lingering in corners later, adding a second unit near those areas will boost the effect.
Q: The product says it’s silent—does that mean I won’t hear any buzzing or high-pitched sounds at all? I’m pretty sensitive to weird noises, so this matters a lot to me.
A: Totally silent for humans! The ultrasonic waves target only the auditory and nervous systems of pests like rodents and cockroaches—we can’t pick up those frequencies at all. The only sign the device is working is the blue LED light that turns on when you plug it in. No buzzing, no humming, just quiet pest control.
Q: The instructions say to plug it in 30–70 inches off the floor—why that specific height? What happens if I plug it in lower, like right next to the baseboard where mice hang out?
A: That 30–70 inch height is where the ultrasonic waves spread most evenly across the room. If you plug it too low (like near baseboards), furniture or floor clutter might block the waves, making it less effective at reaching pests hiding in other spots. Sticking to that height ensures the waves cover more nooks and crannies where pests like to nest.
Q: I want to use these repellers in my warehouse, which has lots of metal shelves and concrete walls. Will the ultrasonic waves work through those materials, or do I need to place a unit in every small section?
A: Ultrasonic waves don’t pass through solid materials like metal shelves or concrete walls—those will block the signal completely. For your warehouse, you’ll need to place one unit per enclosed section or aisle, especially around areas where pests are most active (like storage bins or loading docks). That way, every spot gets covered with the repellent waves.
Q: The repeller uses only 3–5 watts—does that mean it’s super energy-efficient? I plan to leave 10 units plugged in 24/7 in my office building, so I’m worried about the electricity bill.
A: Super energy-efficient! 3–5 watts is way less than a standard light bulb—running one unit 24/7 for a whole month costs just a few cents on your electricity bill. Even with all 10 units plugged in nonstop, the extra cost will be barely noticeable. It’s a low-effort, low-cost way to keep your office pest-free.
