Thank you for sharing your thoughts on your purchase, Abbie. Because our Quality Team is very engaged in our factories, we're confident your Zevo Flying Insect Trap Refill Cartridges will catch the most bugs when you do what you can to make the Trap more attractive to all flies, gnats, and fruit flies. If you can lure more beady eyes to the blue glow shining from the Trap, they'll be mesmerized, having to fly over there and check out what's so pretty. Reduce the lights in the area. Make sure nothing is blocking the Trap. Also, be sure the outlet that's holding the Trap is the best one for all winged pests to see; it's located near where the bugs hang out.
