Sieving mealworms

[Isis]

I was wondering... how do you sieve the mealies from the bran? What size of sieve holes? And do you try to recover all the larvaes that are too small to remain on the sieve?
I am beggining quite a large scale production (about 20-40 containers) but I am not sure about sieving...

I use a powdered gutload because the bran is too large to go through the sieve. I have 4 types of containers for my mealie breeding:

--good-sized ventilated container for mealworms which are generally big enough for the leos to eat

--plastic tub with no substrate for alient

--ventilated plastic container with gutload and veggies for beetles

--small ventilated plastic containers for mealworms that are too small to eat.

Mostly, I rotate the worms as their life cycle proceeds from one container to the next. Every few weeks, I sieve the small containers of tiny mealies. The ones that fall through the sieve go back into the small container to grow. The ones that stay in the sieve get dumped into the ready-for-feeding container.
