Are Sonic Repellents Effective Against Urban Raccoons?

Hey everyone!

I’m at my wit’s end with raccoons tearing up my garbage cans and patio. I bought a “ultrasonic raccoon repellent” from claims to emit high-frequency sounds to scare them off. At first, it seemed to work, no raccoons for a week! But now they’re back, completely unfazed. Are these devices just a placebo for desperate homeowners? I’ve heard raccoons adapt quickly to noise. Has anyone had ​long-term success with sonic repellents? Or should I switch to old-school tactics like ammonia-soaked rags or motion-activated lights?

Bought a $50 ultrasonic device last summer. Raccoons ignored it after 2 nights! Switched to locking my trash cans with bungee cords, 100% effective. Sonic = scam.

Raccoons are too smart for gimmicks. Studies show they habituate to repetitive sounds. Try motion-activated sprinklers, they hate surprises!

My solar-powered sonic repellent works… but only if I move it every 3 days! Raccoons catch on fast. Pair it with ammonia-soaked cotton balls. @NatureLover64 sprinklers freeze in winter, ever had issues?

Sonic devices harm bats and owls. Use chili powder around bins instead! Cheap, natural, and works on possums too.

Left a talk radio station playing all night. Raccoons avoided my yard for a month! Now they’re back… maybe they got used to NPR? @HomeHelperHank where do you place the ammonia?

Most devices use 15-25 kHz frequencies. Raccoons hear up to 50 kHz, but urban noise pollution drowns out the sound. @HomeHelper try alternating radio genres, maybe they hate heavy metal?
