there's also an issue with the flying area a SF needs to mate. If we wanted to keep the flies in a clean environment and have them mate there... would that be possible. I think they need alot of room to fly around in to be able to mate compared to the relatively small space a housefly needs.
Edit: I forgot to mention.... there is also an issue where if other flies came to the culture bin could they pass on any pathogens to the culture even if they were outcompeted later on by the SF? For example houseflies laying eggs on, near or in the SF culture bin?
Our frogs are quite expensive (and sometimes rare). Aside from that no one wants thier entire vivarium or paludarium wiped out from a harmful bacteria or parasite.
