Re: I scrape and reuse the wood frames - I must be introducing some "toxic" elements?
Saw a video on Youtube of FATBEEMAN and his old frames. He dips the frames in a bucket of bleach and water and lets em soak and clean for awhile. Come out lookin just about new and clean as a whistle. I'm sure it's also killing anything detrimental to a hive with the bleach. Just a thought before you go snapping the new foundation in a dirty frame.
