they all died. got black and crispy, I never saw an adult or a pupae.
I had them on oats with pieces of carrot. I watched several videos on it, and read lots.
Would it be the Petsmart worms? do I need to order from a mealworm dealer?
Hi, I am a mealworm breeder, and I can definitely help you on this because I have lots of experience with pet store worms. Keeping them on oats with carrots is exactly what you are supposed to do.
But, make sure they are in a large bin with a screen lid.
PetSmart buys their worms from a company called Timberline, but by the time the containers of mealworms actually make it to your
PetSmart, they can be weeks old and starving.
I've had good, and bad, luck with
PetSmart. Some of my containers have decently healthy worms, and some die off quickly just like yours.
PetSmart should carry "Giant Mealworms" which are regular mealworms that were raised in an environment with extra of their own hormones added. It makes them grow larger, and not pupate as quickly. (However, they are 100% safe to feed to animals. It's just extra of their own hormone. It will not hurt anything) Plus, by the time you buy them, those "Giant Mealworms" are old and big and should be ready to turn into beetles. There are many myths about Giant Mealworms, and one is that they can't have babies. WRONG, they most certainly are sterile and can have many babies. I started my whole colony off of 100 Giant Mealworms, and now I've had thousands of my own mealworms. Just to let you know, their babies will be regular mealworms and not Giant Mealworms. You'd have to buy the hormone to make their babies be Giant (Which is not neccesary). So anyway, get rid of those dead worms and buy about 150 Giant Mealworms. Hope this helps!
Good luck with your colony!
