I bought this to try to reduce the bug population around our house. It is hanging in the yard about 7 feet up and 25 feet away from our patio. It does the job well. Within a week of installation we noticed a difference in mosquitoes and beetles. I feed the pets on the patio and the flies love the food. I started leaving this light on 24/7 and again within a week there was hardly a fly to be found. I put a bucket on the ground under the light and the variety of dead insects was amazing. On occasion a lizard going after bugs or a giant moth will get in it. That requires turning the light off and removing the intruder.
