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.
Bottom watering or mosquito bits.
Mosquito bits?
It’s a brand of little dry nuggets containing Bacillus thuringiensis israelensis (BTI). You infuse the water with it; the larvae ingest it, stop eating, and starve.
You have to be persistent for several weeks, though, and ideally also kill the adults – sticky paper gnat traps work well for this.
A combination of both of these got rid of my gnats after a few watering cycles.
