I know that calciworms are the larva stage of black soldier flies and houseflies are so common. I have been lucky to be able to catch 2 houseflies by hand without killing them. Now I know the vent in my room is completely open and has been ever since I got a wood floor. The vent cover won't fit. But houseflies can breed at room temperature so I won't have to worry about heat or cold. Just a little problem. Well actually 2. I don't know how I can have the container ventilated without the flies escaping and when they do escape, it is hard for me to catch them. And, I am not sure if it is safe for me to breed them as feeder insects. I mean no the houseflies in my house don't eat poop, just fruit. But still, is it safe to feed a bearded dragon houseflies? I don't have a bearded dragon yet but my momma is building a castle for him/her in the enclosure. And I have done my research on what bearded dragons need and how often to feed them at different stages of their lives. And I am currently doing research on how to breed feeder insects so that hopefully, I only have to buy the insects once a few weeks before I get the bearded dragon.
