We have a big container here in the house for raising mealworms, but it starts getting decrepit after a few months. It’s more frass than food, the adult beetles start taking over, and while it’s still productive for now, the writing is on the wall — a few more months and I’ll be dumping it into the compost bin. If I were smart, I’d start a fresh mealworm colony now, before the old one fades away.
I am smart, S-M-R-T, so that’s what I did this morning. Here’s what a mealworm paradise looks like:
I poured in a mix of oats and cornmeal, with some barley for variety, and chopped up some old carrots for gnawing on. Then I transferred a bunch of larvae from the old colony, and also a few adults to start laying eggs. The cardboard and toilet paper rolls are for shelter, and they also lay eggs on those. Now I wait for the population to explode, and then I can start harvesting the worms for the more important spider colony.
Biology is so easy. Provide the right environment, and your subjects proliferate with little effort on your part.
