I found a bunch of mealworms in some old dog treats!!! So now I have them in a 5 quart plastic box with oatmeal and cereal (plus pieces of potato for moisture...) while I wait for them to multiply like crazy (I did find a few adult beetles there, too) and I will not only have my own stash of chick treats, but their guano is good for the garden too! Wonder how long it will take to get enough mealworm guano to do any good in the garden...
