Nice product, I tried to use it indoors to get rid of some ladybugs, it only got 1 in 3 days. But I have had this product before and I know it will work outside for other flying insects. Only drawback is bottom part of item is a grate so it does not hold anything zapped. But I hooked up a metal tray with wires holding it underneath the unit for the time being. It has run for 5 days 24 hrs. and cord is cool to the touch.
