SBFL are some of the best composters money can buy, if you look for it there is a whole community build around just these flies (there is even a forum!) Despite all this I was trying REALLY HARD to get a SBF breeding op going and the weirdest thing happened. I got at least 100 to pupate into flies... BUT NONE OF THEM BRED!? WTF? Right I mean what the heck why are they being picky they're just hairy maggots and then mouthless flies.. Anyone know why this might be the case??? Really sad because I wanted to become a serious SBL breeder to help the Cham Breeder community by lowering the costs a tiny bit. Your average BSF are actually pretty pricey, not Dubia level but still,. Like you can't even get over 500 for less than $20 typically, and you can get that for price for crickets easily, even though crickets are more tricky to breed typically. Any way can anyone help me figure this out?
