Dang, that is what I was afraid of! I have so many worms I couldn't tell you...I started back in November.....I have a three drawer system in a stacking tower with the top beetle drawer having a screen on the bottom for the baby worms to fall through to the middle bin. The bottom bin is a mixture of all since my screen originally broke and it was to much to try and sort the worms, pupa, and beetles. I have a ton of new baby worms in the middle bin that are just barely big enough to see....it is my second hatch baby worms if that tells you have many I have! What will the grain mites do to the meal worms?
Also I will have to find another place to keep the meal worms as I don't want to bug bomb the garage, my kitty sleeps in the garage at night and I don't want that stuff around her, but thank you for the suggestion!
