I was so happy to find an affordable insect killer living in a place that is infested with mosquitos every summer. I hung the Flowtron next to my chicken coop and near the above-ground pool where I am certain there was plenty. I loved turning it on every evening to hear those mosquitos get zapped away. I can say that I saw an obvious reduction of pests in my backyard, but they weren't completely gone. I used an old dry toothbrush to clean the metal grate when it would get blocked up with carcasses. But many did end up on the ground and I think my chickens enjoyed the treat when I let them roam.
