Hi everyone!
I’ve been dealing with rats in my attic for months and recently bought an ultrasonic repellent that claims to drive them away with high-frequency sounds. After two weeks, I’m still hearing scratching noises at night! Are these devices just a scam, or am I using them wrong?
Ultrasonic devices work best in open, unobstructed spaces. Clutter absorbs sound waves. @NoMoreRodents, pair them with steel wool in holes and peppermint oil sprays. Rats hate multi-sensory attacks!
Most devices emit 20-60 kHz, rats hear up to 76 kHz. They might avoid the area initially, but studies show they adapt within weeks. Rotate sound frequencies if your device allows!
I had a severe infestation, and my ultrasonic device worked wonders! Placed 3 units around the attic and kept them on 24/7. Rats vanished in 10 days. Tip: Clean the area first to reduce sound barriers!
Ultrasonic waves don’t harm rats, but they’re also useless against determined infestations. Try predator urine (e.g., fox urine) near entry points. Nature’s scare tactic!
Sound devices are overpriced noise-makers. Crush mothballs into rat holes, they hate the smell. Just keep kids/pets away!
A 2023 study found ultrasonic devices reduced rat activity by 30% in labs but had no impact in real-world settings. Focus on sealing gaps and removing food sources!
My neighbor’s ultrasonic device gave me headaches! Check if your model emits low-frequency hums. @NoMoreRodents, maybe your attic vibrations are ineffective?
Bought a $50 device, rats partied harder. Now using bright LED strobe lights. They avoid lit areas at night. Cheap and humane!
Update: Moved the device to a central spot, added peppermint cotton balls. Scratching stopped for 3 days! Maybe combo methods work. Thanks all!
