The refill does not seem to catch flies like the starter set i purchased. this refill only catches fruit flies. no files on the film. on the original film there were several.

I'm obsessed with these. I just changed the cartridge and it's gotten SO many new gnats!! I love house plants but they draw gnats, as does the fruit bowl. These are great refills, super sticky!!

This product is the best. I was inundated with Flys, gnats, etc but no more. Been using it for a year...no more flying things and no more smelly fly spray.

Love it when enough bugs are trapped throw the full trap away. Doesn’t cause a mess. It’s wonderful. A little expensive but its worth it forme. Mosquitoes eat me up in summer. This was a great help

Same as other people, they are sending out a 2 pack instead of a 12 pack. They must have their inventory mixed up with Walmart because Sams club doesn't even sell a 2 pack. Got the refund but was really hoping to get the 12 pack.

The Best! The only thing that actual works for catching gnats in the house. No more vinegar mixtures. I keep a Zevo plugged in year around to prevent excessive gnats in the house.

I plugged it next to the patio door, I have a very bright light outside and every time I let the dog in I0 would have millions of mosquitoes. problem solved, I already replaced it lasted a couple of weeks, mosquitoes and flies

I asked for two packs of 2. One was shopped and the other was substituted for a box of 4. So I have 6 now. Why not substitute both for a box of 4 if I only needed 4? Probably because of the money… smh

[This review was collected as part of a promotion.] This really works! It catches all the bugs that come in when the door's open. I love how easy it is to pop in a new refill no mess at all. So simple and effective. Highly recommend!

The zappers work well in catching knats, I have purchased 12 of the refill kits pack 2 each. I have had to replace the refill one a week due to knats crawling on refill top edge when it gets close to partially full.
