How to catch fungus gnats says my father in law.
Looks like he’s right, also all organic or could be. Coffee, cream and sugar

Apple cider vinegar with a drop of dawn dish soap (optional) works great too.

This will also work. It won’t do anything for larvae that are in soil though, so make a plan to get rid of those. Bt soil drench is pretty effective if you need.

Yeah they use that at the local bowling alley
Don’t put up with fungus gnats, they will eventually drive you mad. Traps, sticky papers, gnat sand and whatever else shops sell don’t do a damn thing to get rid of them. And unless you break the lifecycle, you will always have fungus gnats.
There are 3 ways to stop fungus gnats.
- Parasitic nematodes that eat the fungus gnat larvae.
- Parasitic mites that eat fungus gnats and their larvae.
- Bacillus thuringiensis is a bacteria that kills fungus gnats and their larvae.
1 and 2 need warm conditions to work and won’t work at temperatures below 18C (64F). But both break the gnat’s life cycle and are excellent in warm conditions. It takes about 2 weeks before you see the gnats reduce in numbers but when it happens they stop appearing.
3 is a bacteria that works in most cold or warm conditions and you sprinkle or water on the soil and the gnats and their larvae pick it up and it destroys them from the inside.
You can get all 3 online, just do a Google search for them and order away. Do all your plants indoors and outdoors and in a couple of weeks you wil no longer have fungus gnats.
