Oh man, I dont think I can have live flies in my fridge (but they can go in the garage fridge when thats in )
I keep the spikes refridgerated and I drop a few, plus the black BSFL larva into an old BSFL cup with a hole in the lid. I have one in each chams cage. My hope is that they are morphing and crawling out for sporadic snacking. Haven’t seen any flies but my guys don’t play when there is food around.
I dont want to jinx myself but for the most part my guys eat whatever I offer. They get a variety daily. The only variance I have is that 1 likes kale and silkies, and 1 doesn’t.
