Living in Texas, we are use to a LOT of bugs. I have both my front porch light and the light between my garage set to auto on when motion is detected and then go to dim instead of completely off when the motion is on. The result was that we could not walk out front without getting accosted by dozens upon dozens of bugs. I put this up about 25 feet from the front porch and within a week, all but a very few of the bugs are gone.
