Some fungus gnats have showed up, and unlike what some blog posts have said, they don’t seem to be attracted to apple cider vinegar. Has anyone found a trap that gets rid of these little things? I’ve put the plants outside for now, hoping that will dry them out and make the flies fly away.

    I’ve tried a lot of methods. I haven’t eliminated them but they are no longer a nuisance.

    Hydrogen peroxide 1:4 in water will kill the larvae in the soil. Unfortunately, it also kills some plants like parsley, thyme, oregano.

    I add some pea gravel, sand, other grit to the surface of the soil when I bring my plants indoors. That seems to help deter them.

    I see the most results with sticky yellow paper traps you can get off Amazon. They’re cheap, effective and one sheet will last about 4ish months. Helps keep the numbers of adults down.
