Zevo Flying Insect Trap Refill: 3 Indoor Light Trap Refill Cartridges Capture House Flies, Fruit Flies, and Gnats (3 Refill Cartridges)

I think these things are over-priced, but they definitely work. I bought them for fruit flies from home-grown tomatoes and gnats from a houseplant that spent time outdoors. Not only do those little buggers stick to these traps, but also moths, mosquitos, %26 flies that find their way inside when humans spend a lot of time outdoors. The bugs are definitely attracted to the light, so more are caught overnight than in the daylight. I like that you can rotate the trap 90 degrees in a tight space. It's easy to replace the sticky part if the trap gets too full. While well-designed, I still think they're over-priced, but I guess we're paying for the idea %26 engineering, cause there doesn't seem to be a lot of competition readily available.

These filters work like a magnet to trap knots especially! You need to place them where the flying insects are, mine are in the kitchen where my fruit etc. Is located. They must be placed in a more dark area away from light. I can guarantee you that at night when lights are out, those critters will fly right to that blue light on Zevo!! I highly recommend these. If you place them correctly, they WILL work!!😊
