Oh no, not at all. They smell like their substrate(Oats), and Oats don't really have a smell so nope. Even the dried up banana peels and potatoes don't have a smell.
Oh ya duhh. Sorry about that MFKers. Thanks for reminding me, I'll get them today or tommorow. They hide alot right now in the oats. I'll get some though.
Forgot to say some info. I put the pupa's in the little green drawer system. And the big system has 2 drawers with mealworms and 1 drawer with beetles.
