This is the second Flowtron Insect Killer that we have purchased and they are very effective.  Our first was a 1 acre model which we used at our cottage in Maine.  Now we are back in Arizona and low and behold we are being pestered for the first time with mosquitoes in the desert.  Watch out mosquitoes the insect killer is being installed tomorrow.  Just hope the neighbors don't get upset with the snapping and buzzing during the night because we are declaring war against these pesky insects.  You can't go wrong with one of these insect killer lights in your yard.
