Comparing Bug Traps: Zevo's UV Light & Mess-Free Test Wins We’ve tested our fair share of bug traps, but the Zevo Flying Insect Trap & Cartridge has truly impressed us with its simplicity and effectiveness. The plug-in device, powered by blue and UV light, proactively lures gnats, house flies, and fruit flies into its attractant cartridge. The best part? It’s completely mess-free—no bait spillage or smudgy traps to clean. We set it in our kitchen and noticed a dramatic drop in fly activity within hours. The spherical design blends seamlessly into any room, and the reusable cartridge (sold separately) ensures long-term use. While some traps leave unpleasant residue, this system operates quietly, efficiently, and without the fuss. For anyone tired of fly swatters and sprays, the Zevo’s UV-powered precision and tidy operation make it a standout choice.
