I’m considering buying ultrasonic pest repellers for my home, but I have two cats. Are they safe for pets?

Most reputable brands claim they are pet-safe, especially for cats and dogs, but I’ve read some pets might still hear the high-frequency noise. It can cause discomfort for some animals.

Actually, my vet mentioned that they can be safe, but it’s essential to monitor your pets’ behavior when you first use the device. Each pet may react differently.

Agreed. Pay attention to any signs of stress in your cats. If they seem unaffected, the chances are that the frequency isn’t bothering them.

I’ve been considering buying ultrasonic pest repellers for my home but I’m worried about their safety. Has anyone used these and found them to be safe for children and pets?

I use them at my place, and they seem pretty safe. My dog doesn’t even react to them. As for kids, I’m not sure, but I think the frequency is too high for humans to hear.

My sister has had one in her baby’s room for months. No issues! Apparently, the sounds are at a frequency that pests can hear but not people, or so the label says.

Oh yes, I understand that ultrasonic frequencies are inaudible to humans, but I’m worried about other factors

I’ve been a tech enthusiast for years, and from what I know, most ultrasonic pest repellers should be safe. They generally operate in a frequency range that is beyond human hearing. However, too much reliance on them might not be the best solution for pest control overall.

Yes, it would be nice if we could find some scientific evidence

I agree with you. They’re safe because humans can’t hear them. My only worry is that pests might get used to the noise over time, making them ineffective. We should probably consider additional pest control methods.

I read an article saying that some pets, especially dogs, might be sensitive to the high-pitched noise. My neighbor stopped using hers because her dog was acting anxious and couldn’t sleep.

Honestly, I’m skeptical. People claim ultrasonic devices are harmless, but I wonder if there are any long-term effects on pets or even humans that we don’t know about.

I’ve used one in my living room with no issues, my dog and cat seem totally unaffected. Of course, I keep it turned off when they’re sleeping nearby, just in case.

@SoundSkeptic You’re right to question that. I looked into some studies, and while really high-frequency levels can be irritating to rodents, the safety margin for humans and pets is still largely untested.

From my experience, the only “safe” problem is that they barely work. I haven’t noticed any difference in pest activity—and I run it 24/7.

I tried building my own ultrasonic repeller with a tone generator. It scared off a few mice for a few days, then they came back. I ended up using traps instead—it just works.

My neighbor swears by them, but I didn’t hear a thing—and neither did my pets. I’m convinced it’s mostly just placebo effect with a buzzer.

I started monitoring a few devices over a month, and rats still showed up—though maybe less frequently. Hard to say if it was the device or fewer food sources.

Personally, I’d choose physical barriers or natural deterrents over ultrasonic gadgets. Seal gaps, keep things clean, that works for me every time.
