I sold 2 nucs this weekend and asked the guy for new frames, with foundation, in exchange for the ones that came in the nucs. I notice that these new frames reek of moth balls. I left them outside for the last couple of days and they are still strong. I actually had to move them when my family wanted to eat out on the deck last night. Should I just pitch these frames or will they eventually air out. I also think this will make me rethink the whole exchange frame thing when selling nucs.
