done the work
so far so good, most gnats disappear. still see adult gnats but very few and they might come from the old larve.

Don't bother - it doesn't work
Everywhere I go in my house I see tiny black flies. As soon as I sit down they come looking for me and annoy me by flying around in front of my eyes. When I go to swat them they disappear, only to reappear a few moments later! I bought this Fungus Gnat Killer and used it as per the instructions. However, it has made not a ha'porth of difference. We still have flies. They are obviously coming from the compost I bought to repot a Peace Lily plant that had outgrown its pot. It was so big I split it into two plants so have twice the number of flies I would have had if I'd just repotted it as one plant! I put yellow bug catcher stickies in all of my plants which, as you can see, have been very effective. The photos show both sides of the two stickies I put in the worst affected plant just a week ago!

Very good spray. I gave it 4 stars because it’s a bit pricey and it doesn’t last very long

Not an instant kill in my experience
I’ve treated my houseplants 5-6 times with this Fungus Gnat killer. I’m seeing slightly fewer flying gnats but I’m not convinced it’s going to eradicate them completely, in which case they’re going to return:( I expected quick kill. Maybe my expectations were too high. I’ll persevere anyway with the regular spraying.

Not Very Effective for Me
I tried this trap to deal with a gnat problem, but unfortunately I’m still seeing gnats flying around — it doesn’t seem to be very effective in my experience. Given that it didn’t solve the issue, I probably wouldn’t buy it again. Update: The seller reached out after my review to acknowledge the feedback. While the product didn’t work for me initially, I appreciate them taking the time to respond, and I may try it again in future to see if it helps.

Useless - does not work
Absolutely hopeless. Do not buy this stuff - it does not work. The pump mechanism failed after a couple of days. The fungus gnats seem to thrive on the stuff. I’ve had to move the plants outside to a shed to try and clear the house of small flies. In short - an absolute rip-off. Avoid!
