Oh nice, thanks for all the info. This is actually the first time I’ve had gnats, so I’m still learning how to deal with them. From what I’ve read and what others have told me it’s basically just about interrupting their life cycle enough to keep them under control. Yellow cards for the adults, and something to kill the eggs under the surface. I’ll definitely look into nematodes. Sounds easier, and I like the sound of that better than dumping a bunch of shit designed to kill stuff in my soil.The MicrobeLift BMC is the concentrated version of the mosquito dunks,
and the stuff works well, but not as good as getting these guys----->

Just have to get them in the soil before there's a problem.
I tried it all, play sand (about an inch or two) covering the top soil, apple cider traps, yellow sticky traps 3 to a pot average... I tried it all. The predatory insects handle it the best.
I've only recently have begun to deal with the rest of the insect world, flies and mosquitos' coming in from outside the garage. The lights are a huge attraction. It hasn't overtaken my tent so that's a relief. The few yellow traps I do have up are doing the job.
