If a person does what they can to keep their stages separate, how would they go about doing so? I have heard from many sources that you are supposed to put a screen on the bottom of your beetle bin so you can collect the eggs, but what is the best size of screen to use without losing too much bedding? People always say keep the frass from the beetles, as it has eggs and larvae in it, so is the frass harmful to the eggs/hatchlings, and could it be separated from them without losing any or harming the eggs/larvae (how fine of mesh is required)? When do the offspring of the beetles need bedding/vegetation?
Someone on youtube was able to sieve out his mealworms from his beetles and pupae using size 6 mesh, the pupae and beetles were chubby enough to stay in the sieve, and the mealworms were narrow enough to slip through the sieve. I saw a mesh sizing chart online, and size 6 mesh has holes that are 3.35 mm in diameter, but I am only able to find mesh that is 3.15 mm in diameter and the holes in that are diamond not square so maybe the mealworms might not pass through that, which would not be good. Anyway size 6 mesh seems to be the magic number and I cant seem to find any anywhere thats exactly size 6. Does anyone know of any good sources for mesh that is labeled by size?
Do people sieve their mealworms based on size if they are seeing too much size variation, or would this add extra unnecessary labor? Are the mealworms from the same batch smaller because they are younger?
I am getting 1000 mealworms tomorrow in the mail, so prep is the next step!
I intend to make an auto sieve further down the road, something that would slowly funnel the worms/bedding into a jiggling sieve pan.
Any advice would be much appreciated.
