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.
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.
