Buy your mealworms early

[Matador]

Thanks for the reminder Kent.  Last year local supplies seemed sketchy and it will probably be worse this year.  How do you store your worms?

I put my mealworms in a sealed container (with holes in the lid) in some old grain that I have.  They store fine in my unheated garage (stays above freezing) until it starts to get warm, in the spring, when I move them into my bait fridge.

What is the advantage to storing them in the grain?
