ADORIC Ultrasonic Pest Repeller, Mouse Repeller Plug in Pest Control Ultrasonic Insect Repellent For Cockroach, Mice, Rodents, Spiders, Flies, Mosquitoes, Ants, Fleas(4 Pack)

Since using the plug ins (alongside peppermint oil dotted about) I’ve no spiders, flies, or mice. I live in the countryside and it’s become a problem but all the pests seem to have evacuated. I’m very happy thank you

Absolute useless. Only good thing is the blue light. Apart from that it does nothing.

Instructions say it could take weeks to reach peak effectiveness, so can't really tell if it's working.

I thought it had worked as not seen a mouse which is vital as I have an Airbnb and still getting reports of mice even though they are fitted all over so not convinced of the effectivemess of these type of devices and will probably just start using mice poison

They have not stopped flies or other insects listed on advert. Have had plugged in at higher and lower sockets but does NOT deter insects.

as above. don't waste your money.

Difficult to say how well these work as really have only put them in situe for a couple of days.I used to get home from being out for a couple of hours to see my kitchen window frame was black with the number of flies perched on it - never had this before I had the windows replaced a few months ago and no idea where the flies are coming from as the house was all closed up while I was out!I only currently have 2 plugged in, in the kitchen and in the porch by the back door. The number offlies since that find their way into the house has dropped but only time will tell if they are worth buying !

Seems to have lessened the sight of pests
