There's way more coming out of the culture than my colonies (and plants) can eat. Can they be frozen and used as needed?

Just be aware of how long you have them frozen. Stuff goes bad no matter how cold it is.

my meal worms live in the freezer, and they are just fine. after a couple of minutes they are mobilized and ready for action. not sure if its the same for fruit flies

If you mean freezer, as water freezing, then you have magic meal worms. Before, I have had meal worms live in the fridge, which they kind of hibernate, and do not pupate at that temperature. Fruit flies also go into some kind of dormancy in the fridge, but die after a few minutes in the freezer.

 

 

For the record, my definition of fridge is: Close to the freezing point of water, but still above- water remains liquid.

                                                  freezer:   Below freezing point of water- water becomes ice.

not in my area. we refer to fridges as those carry-along bags that you can put drinks in
