We've had a mealworm farm for about 3 months in dirt in a large aquarium. It is teaming with the beetles, however, when I search for the "worms" there are none. I see dried up ones, and adult ones, but where are the "worms"?. We have been feeding the beetles to the chicks just because that is what we have. Advice? And believe me, I have looked for the grubs.
