Maxtrv 4 Pack Electric Bug Zapper, Plug in Mosquito Killer with UV LED Night Light, Electronic Insect Fly Trap for Indoor Outdoor Use

My apartment seemed to be full of gnats for some unknown reason, and it was becoming increasingly frustrating that they would fly up to every light source like computer screens, tvs, and even candles. I decided to try these lights out before I went with a more expensive option, and they work great! I put one in my bedroom, one in my bathroom, one in the kitchen, and I gave one to my roommate. The one in the bathroom is the most effective because it gets truly dark in there, but I still could see gnats killed in the ones in my room and kitchen. You can pop the plastic cover off of the lights to clean them easily. These lights were a great purchase!

This gnat killer works perfectly! The picture I have is after four days of it being on and is 1 of 2 I have in my bedroom. I've seen videos of people filming gnats right near these and not being attracted to them but that video was taken in daylight. These work best at Night when it's the brightest light source!If you have seen any gnat flying around in your house get these and just leave them on. They hardly consume any electricity and they're extremely effective.Best way to clean them is to get a air duster and blow them off.

I PUT THIS OVERNIGHT. NEXT TO A LARGE BUNCH OF FLIES. NOTHING. IT WAS ON ALL NIGHT LONG AND NOTHING HAPPENED. THERE IS NO RATING LOW ENOUGH FOR THIS SILLY THING.

Received these in a timely manner. Very cheap feeling. They have not killed one fruit fly/gnat or house flies. They have been plugged in for a few weeks now and it has not done anything. Don't waste your money. Very unsatisfied.

The media could not be loaded.  No funciona, tiene en tres días puesto las lámparas y no atrae a los mosquitos. Siguen estando alrededor o en la pared, pero no en las lámparas. No los recomiendo!

Found myself holding it right in front of my face and the gnats still tried to fly up my nose. Didn’t attract Dudley except for dust.

It appears that the device doesn’t attract much of anything. I have found gnat bodies on my counter next to the little counter top compost bin but none on the zapper’s grid behind the blue attractor lights. Works as a nice night light though.

Had an infestation of fungus flies in my house. Left these on at night with all the other lights off and they work like a dream. Would highly recommend! Also easy to clean.
