Cooking safety and cricket flour
Probably like any other dry good, in a cool dark room temeperature, sealed container.  Since it is dessicated, it should be essentially shelf stable.   You might get a longer shelf life in the freezer, but that should not be necessary.  In any case, you should follow the manufacturer instructions.
That depends on the item, and how much moisture it has.   Very dry cracker like items no.  Very moist items, certainly.  In between, you probably have a day to two days, just like any other baked good.
According to one Thailand based manufacturer (breeder?  farmer?)  the shelf life is two years.  They do not indicate refrigeration is required.
