Ok,I see why you seperate them.I found a simple way to slow down the development of regular mealworms,not sure if everyone knows the trick or not,I pull out a couple hundred mealworms and refridgerste them for a few weeks,this forces them into dormancy.
After a few week in the fridge,back to the colony they go,by doing this,I maintain a year round supply of bait,this is how I control And manage my colony.Again great video,
