Raising mealworms

[madchicklady]

I ended up making the setup in the following video. I found the one tank technique got messy quickly for me ( what with all the skin shedding, pooping, and dead mealworms,) but I didn't want a three drawer system as that seemed a little too complicated for me to maintain.

I used the same setup. I have one question. I started to get beetles about 2 1/2 weeks ago. How long before I see baby mealworms?
