Zevo bugs trap. It has been few months already since i am using it and it actually helps a lot. The blue light is soft, no smell or noise, and after a day I could already see the gnats stuck inside. Super easy, I just plugged it in and it keeps the bugs away from my plants. I’m really happy with it. The device goes together with 2 cartridges. Very convenient in use just pull of plastic film and wait until the flies will stick to it. I even see it catches mosquitoes. You can see how many of them stick to the plastic film.
