thanks for the tip I know bean beetles can be obtained from Josh's and cultured in mason jars or plastic cups with proper lids and they live off of dried beans and peas so are cheap to feed. I also know that before disposing of the unused part of the culture it is wise to put it in the freezer for a few days so that they do not spread from the trash. I will suggest them to my husband since we need to keep five mouths fed now and we had a catastrophic fly culture crash. thankfully we can get cultures of flies from local pet stores, but a back up food supply would be very helpful.
