I also moved a bunch of the seedlings from the house out into the cold frame. I have a nasty infestation of fungus gnats, so last night I watered them with a watering can of mosquito dunk infused water to help kill the larva. We'll see if that works. I did a bunch of research on the internet and other than practically starving the plants to death by letting the soil get super dry the mosquito dunk tip seems to be the most agreed upon. Such annoying little things!
