Review on 🚫 Ultrasonic Pest Repeller 6 Pack - Electronic Indoor Pest Repellent Plug in for Insects, Mosquitoes, Roaches, Fleas, Mice, Spiders, Ants - Safe for Humans & Pets - White by Shannon Redd

I don't understand what's going on with product performance/value/suitability these days. but SOMETHING MUST give. I came home to a fruit fly problem in a couple of rooms in my house. I've used this measure before, not the brand. I wish I could take a picture - the flies froze on this device connected to the network. So what did I spend money on? Small blue indicator? Because they don't emit a frequency. I have recording studio gear - the sensitivity is CRAZY. During our last earthquake, we could hear the rocks moving beneath us. But NOTHING, except the transfer of energy from the exit to these objects. So crazy!
