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.

This stuff right here was what finally did away with them for me https://www.amazon.com/gp/aw/d/B007UTE55A

Excerpt taken from the reviews: "This is a bioinsecticide. A Larvicide (Bacillus thuringiensis) or Bt, and acts on the larvae of insects. Very concentrated. Larvae eat the bacteria and essentially die. It has a short life but works very effectively to control mosquitoes and fungus gnat larvae. You need to use this product regularly to break the life cycles of gnats and mosquitoes as they constantly lay eggs that hatch into larvae. This product kills larvae only, not eggs or adult insects."
