They can store for years without extracting as long as rodents, bugs or trauma don't befall them.
I don't have a garage or honey shed to store my supers while waiting for extraction, so I bring them inside to the kitchen and store in a stack. Just make sure you lay down craft paper under the stack since the frames do drip. I only deal with 6 boxes at a time.
