Problem with ants. Never feels good killing the little critters but at night particularly there were zillions of them on the work surfaces. Not nice.Came to this gizmo with low expectations, but plugged it in where the ants were most likely coming in et voilà, no more ants.For the price, if it continues to work, it's a bargain and a humane way of keeping ants out the house.

I got these for going on holiday. I tried them out before we went and they seemed to work here in the uk. On holiday we still had a few unwelcome visitors so I do t know if they work or not.

The devices come ready to use and are very straightforward. They have been in place less than 24 hours and already there is a difference. Normally in this weather when the patio doors are open we get lots of flies and other insects but there has been none since we plugged in the devices.

To be honest did not notice any difference in bug control, Still got bitten by Mosquitoes abroad. Cannot say with any confidence that this product works but it was fairly cheap so gave it a go.
