Ultrasonic Pest Repeller, [2018 Upgraded] ESEOE Electronic Plug in Insect Repellent, Ultrasonic Spider Mosquito Rat Repellent, Repels Mouse Bedbug Roaches 2 Pack Black

Didn’t find these help at all

Live in desert area where spiders, beetles, ants and woodlice are rampant. Bought two different types of deterent units (one style is dual action with ultrasonic and electromagnetic function). The dual action certainly seems to work better than this. The jury is still out on these. Noted - neither appear to work on woodlice which if anything have doubled since installation. Maybe they attract them?

Easy to install and seems good value compared to others, It just doesn’t work at all. The mouse was chilling next to it. In the end we got a cat as it’s the best option

Bought following a tip that these keeps ants away after a swarm of ants appeared on our patio. Plugged in for a week but no joy, still there, so got a bait station instead which did the job in a day.Left these plugged in however and left patio door open yesterday due to the heat. We noticed that all of the flies, flying insects, wasps etc were flying but getting stuck at the door and not coming in.We decided to test turning it off and low and behold, kitchen full of flies and mozzies. Turned it on and bam, they left!!!Works incredibly well for flying insects but no so much for ants!

It is not effective as you expect. No point of buying.

I found this product useful as i was able to use it inside the house and it never bothered my pets at all! It got rid of all the pesky insects that was about and It was very quite and never made a noise. Overall this product i found extremely great ! I would highly recommend this product to other users as it came super fast and it is really easy to set up and use.

Have the back door open all the time for the dog.Was getting far to much wildlife! - bugs, flies, even a mouse!Seems to of kept the mouse away but has done nothing to keep flies out.

Total waste of money. They don't work - in fact spiders built a web around them! You're advised to leave in place for a few weeks to become most effective but I suspect this is so you miss the returns window so you can't get your money back.
