I started my mealworm colony Aug 21st with a 1000 in a single plastic bin using wheat bran. In a weeks started seeing pupas, then beetles. Now I got a whole lot of pupa & beetles galore, hardly any mealworms. Reading about moisture, I lay brown paper on the wheat bran, putting veggies, fruit, crushed egg shells on the paper. The mealworm/beetles eat through the paper as well as crawl up on to eat. I never know if they get enough as I change out the "food" every few days.
Today I was going to separate the beetles from any remaining mealworms, thinking it would be "easier" but after reading rottnwarrior post and trying, I gave up. Single bin it will be. I've put some empty paper rolls in the bin, find the beetles all congregate under the paper and the wheat bran under it sunken in...assuming it's being eaten?
It's a good thing the "farm" doesn't need much care, makes the waiting "easier". With more beetles than mealworms now, I'm hoping I'm doing this right. Dumped some rolled oat into the wheat bran today, found my chickens love the oats more than the freeze dried mealworms. Hope they like the live mealworms.
Anyone got any other suggestions?
