Myself...I don't! I have tried and have lost eggs and micromealies!! So I just let it build up then replace the bran when the mealies get large enough to remove without loss. Best way I've found with little to no loss.Got a question about mealworm farming so hopefully this is the right thread to add to instead of starting a new one.
Is there a good way to separate the frass from tiny worms and eggs? I move the wheat bran (containing eggs) from the beetle bins and add them to my worm bin. So my worm bin always has various stages including eggs and very tiny worms. More and More frass is building up because I can't clean it without loosing small worms and eggs.
How do you all do it? Thanks.
