Looks pretty good. I'd put a paper towel or two over your substrate/veges to help stop them drying out as quickly.
The only thing that appears to be a threat is heat, so you need to get humidity up without creating mould.
Did a google and the beetles are the first to suffer excessive heat...
If they're young beetles, that's probably going to be enough. Say at minimum you have 10 females laying eggs.
I don't know how many eggs they lay per day...everyone seems to have different number.
Time to get to a second generation of worms will be the issue.
if I set up beetles in the winter...
Wheat bran is best for the nutrition they get. My worms never went for potato, so I used carrot.
I once read that more is not better, but that being said, it is winter here in au.
I have been giving over the past few weeks the wheat bran as the substrate and chicken starter/mash?, for moisture...
Hi,
Has anyone had mealworms that curl up at times and roll onto their backs? They eventually become smaller and die.
I can't see any obvious disease, although in the past have battled mould mite.
Thru sheer desperation, I have painted the very tops of some trays with surface spray to kill mould...
