I love my Black Soldier Fly grubs, both because they will eat almost anything and when they mature I can give them to my friends with chickens, ducks and reptiles! However, sometimes, it rather suddenly turns very wet. The grubs don't seem to mind, though I worry that it makes it hard for them to climb out and they are not much fun to handle when they are....slimy.
Does anyone have an idea of why this happens and if there is something I can do (or not do) to prevent it? - Amanda
