Review on ROSUN Bug Zapper: 4000V Electric Mosquito Zapper for Indoor and Outdoor, Waterproof Insect Fly Pest Trap - Effective Mosquito Killer for Home Patio by Andrea Taylor

This is an easy to use insect repellent. You just plug it in and it will destroy any bugs that fly in. Works great indoors. I suspect it's not possible to use it outdoors 24 hours a day, 7 days a week as the plug doesn't seem designed for outdoor use unless you place it under an umbrella or in a covered area. There should be an easily removable tray to get rid of dead bugs, although I haven't had a large enough collection to try it yet. One gripe - there's no on/off button that I could discern. You have to unplug it completely to turn it off. Otherwise, it's always on when connected to a network.
