Review on 🪲 Jricoo 6 Pack Ultrasonic Pest Repeller - Upgraded Electronic Indoor Pest Control for Insects, Mosquitoes, Mice, Cockroaches, Rats, Bugs, Spiders, Ants - White by Anne Nishioka

I was skeptical at first but after months of hearing something on the ceiling above my bedroom I couldn't find a source, even with exterminator I thought it was worth a try. I plugged 4 devices into the bedroom outlets as soon as they arrived, so they activated about 8 hours before bed. No scratching sound that night and not repeated since! The review asks for a "smell" rating, but the product has no smell. I have 2 dogs and the high frequency has not affected them or me. I am happy with the product and plan to order more for the garage and RV. Excellent price. Much easier to use than a mousetrap!
