I used to not be able to leave my porch light on at night because it attracted crickets and flying bugs and they all flew in the same moment I opened the door, um to take the dog out. It drove me crazy I figured there was a 20 percent chance the bugs wouldn't hang around outside my door all night. Well it generally works. I hooked it up to a timer that turns it off in daylight so it runs all night. I never have bugs on the door when I go out of the house. It's also bright enough so I can feel safe walking my dog and see my surroundings. I will buy again.
