I like feed corn. It seems to hold heat better and holds up for more cycles through the microwave than rice does.
Bugs aren't such a problem if the warming bag is heated regularly in the microwave (kills any bugs). Rodents are only a problem if your mother's house already has them.
Rice or flax seed might be more comfortable than feed corn because they have smaller grains but I prefer the greater heat capacity of feed corn.
