Bought the lamp hoping it was going to help with mosquitos on our back porch. I live in Arizona where there aren't too many flying bugs, but mosquitos breed in small damp areas of our neighbors planters -- caused by moisture drip lines running from their air conditioners.  Installed the lamp and bait as per the directions.  Tried it for over a month.  Killed more moths than mosquitos, which is not saying much.  I'm glad other customers are having luck with this unit -- as I think its pretty worthless.
