Getting Rid of Gnats in Fresh Produce?

Every spring/summer when we start bringing in produce from the garden and bananas from the store, we start getting gnats all over. They are worse in the kitchen. I've tried the banana in the container and covered tightly with plastic wrap. It works! Also (tip from my son-in-law) pour apple cider vinegar (enough to cover bottom, plus) into a container add a few drops of dish soap (Dawn, Palmolive, etc.) in vinegar and swirl container a little bit.

You can use Styrofoam cup, small plastic bowl, etc. It does work. You can change the vinegar/soap when needed. I usually change mine on 3rd day. I think this one works the best. Does anyone have any other hints?
