Cheerio-
My son is taking the forever approach to raising mealworms

Every time somebody gives him money (birthday, Christmas, etc.) He uses a SMALL amount of it to buy something towards raising worms - so far, he has a cooler, bedding and food. He wants to get coloring (neon colors are hot sellers here) next, before he gets the actual 'base' worms
I figure, even if it takes a long time, it's his money and he's putting it towards a future income stream, instead of garbage (we don't buy candy/soda/etc - if he wants that garbage, he must pay for it).
