I also plan to setup a red worm composting bin in the same room, and figure that if I keep flies from accessing the worm bin, then nothing else would be a concern.
If you keep BSF in the same room with your worms, it is inevitable the worm bins will wind up with BSF larvae. You might be successful in keeping the adult flies out of your worm bin, but they will lay eggs on and near the bin and the microscopic hatchlings WILL find a way in! This is not necessarily an issue though, since BSF and worms can co-exist in a somewhat symbiotic relationship.

A screened or mesh fabric enclosure might serve to keep the population of BSF contained and increase the likelihood of captive breeding.
