I have a platter w/ dish soap and water, setting under a nite light by my front door, about any insect will go to the light and jump up to it, and fall into the soapy water, ''end of insect". They haven`t been as bad this yr so far, wonder if they drowned in all the rain we had ! lol
We put a pan of soapy water in the bedroom with a candle in the middle. catch 5-30 fleas a night when the little bastards are parking on my dog. I think we killed the cycle as we dont have an issue anymore.
