Hi everyone. I have just started to raise mealworms to feed Bluebirds nesting in my yard. I have started my farm with about 400 beetles collected from my first order (10,000) from an online vendor (maybe one of you). I have a 3 drawer system from WalMart right now but I think I am going to need a bigger (5 drawer) system for sustained operation. How long does it generally take for new larva to hatch from the eggs? Literature indicates 4 - 19 days but mine have been in the substrate for about 23. I just moved them from my basement which has a temperature of 68 degrees to the garage which in now about 84 with a fan blowing. Is my basement causing a slowdown in their activity/survival?
