I decided not to buy preformed patties this year, electing instead to mix my own using dry Ultra-Bee. After two weeks I went to check; finding mold on the patties (as well as a few beetles) I removed that which remained. I would have thought that a preservative would be a part of the mix, but apparently not, or else not in sufficient quantity. I read that, for a preservative, some use Vitamin C (easily available at the feed store) or perhaps add an essential oil mix, like Pro Health or Honey-B-Healthy. Anyone else have this problem much, and if so, what do you add?
