ARGH! I'm sooooooo skeeved out! Bought a big ol' bag of potting soil at Home Depot a couple of weeks ago, and brought it to The Plant Room to warm up. Just got to it last night, and when I opened it, there was a teaming swarm of fruit flies. Ugh! DH brought the bag outside and put it on the patio into the cold. Question: Will below freezing temps (low 20's) kill off fruit fly larvae? Should I return the bag to Home Depot? Bake the soil (icky smell, but if it works...)? Thanks for all answers and input, Pony!
