"Any time you notice a mealworm turn into an alien in your mealworm container, take it out and place it in a small container with other aliens. "
I actually typed a reply to the original post last night when it first appeared, but my computer froze and my post never went up. I think it's funny cuz in my post I referred to the white things as Aliens too! Weird looking things aren't they?
I actually started my colony just cuz I didn't know what else to do with those little things. I have 11 Leos, each with it's own tank and food bowl, and I get about 6 Aliens a day.
I took a medium sized rubbermaid container, drilled some small airholes in it, filled it with oatmeal (not the instant kind) and just keep tossing in the Aliens.
I use the baby mealies for my smallest Leos. I sort through and use the biggest ones to feed the bigger Leos. If I have more worms than I need I toss the extras into another meal worm tub that I keep in the fridge. I don't keep the colony in the fridge, it's on top of it actually.
Good luck to the original poster on your colony (although it's so cheap to buy them online now it's not really worth it from just a financial standpoint, just a nice place to toss the Aliens though)
