They worked great I like them

They do not work at all… only one star because I have to give it a star of some kind.

As a curious gadgeteer and a dad on a mission to banish creepy-crawlies, I ventured into the world of Ultrasonic Pest Repellers, those nifty little devices promising to keep fleas, insects, and rats at bay. Do they work? Well, that's a bit like asking if my lucky socks help my team win - hard to prove, but hey, no losses so far!First off, these gizmos do light up and consume power (yep, my wall outlet confirmed it), so they're not just plastic duds. Whether they emit a critter-scaring sonic boom or a gentle lullaby for pests, I can't scientifically say. My phone's experiments around them didn't reveal much, apart from making me feel like a pseudo-scientist.Now, let's talk bugs, or rather, the lack of them. I can't say my place was a bug metropolis before, but it's still a ghost town for pests now. Is it the repellers? Maybe. But let's not ignore the real MVP here - the soothing blue light. It's like a beacon of peace for my bug-phobic daughter and a sleep aid for her spider nightmares.Value-wise, it's a no-brainer. Six of these for a few bucks? That's like a coffee and a half. Coverage is impressive too, each claiming to guard 1500 square feet - that's a lot of peace of mind per square inch.In conclusion, while I can't vouch for their scientific efficacy, these Ultrasonic Pest Repellers score big on the psychological comfort chart. They're cheap, they cover a lot of ground, and most importantly, they've won over my daughter's heart with their blue-hued nightlight feature. As a dad, that's a win in my book. So, if you're in the market for a little peace (of mind) and quiet (from pests), give them a shot. After all, sometimes the best solutions are the ones that just make you feel better.

This repellant set has been so clutch for us! Got this because we seen an uptick in critters at the house. All this heat draws them to the coolness of the house. Over 2 weeks have virtually disappeared!

So far it’s working hopefully it keeps going on because during the damp weather I get so many ants coming through the slider from the deck.

Used in attic garage and attic. There's a slight sound of you get close, but it's super quiet and convenient. So far so good. They're hasn't been any scrabbling around the last 2 nights

Haven’t noticed if they work yet or not or how often they should be plugged in before changing them! Why else do they send you so many? Don’t have that many available outlets!Just waiting to see if they take care of the bugs & stuff!

I had this pest control plug in for about 2 weeks roaches be climbing on top of the plug in the roaches is not running away not running out the house they are not scared of it i have roaches probably about 3 months and i do not see this machine working i can't say it running up my light bill because my light bill was $100 this month but i don't see it's working we've been having spiders for years i'm going to keep them plugged up because they very cheap and i don't see a high bill yet but some people on here say that you should see some good results after 2 weeks that is not true it's the same thing the same roach problem no change
