rmedgar, I had no problem attracting wild BSF. I live in the country and I'm not sure if they are as plentiful in the suburbs or in cities. I still haven't gotten a good sense of how common they are in the north.

When I first started researching BSF I was sure I had never seen one. I put out scraps and had BSF laying eggs within hours.

DD1, that's a good question. If thebiopod doesn't know off hand I'll test it when I get my colony going again.
