Keep the spikes in the fridge, but not the waxies. The fridge is too cold for the waxies. Keep the waxies in a cold room (about 50 degrees). I keep mine in the utility room down in the basement. I set mine on the floor against the exterior wall and they keep nicely. Change the bedding about once a month if you haven't used them all up in that time. Main thing with waxies is to go through them once in a while and remove any dead ones. Seems like the dead ones poison the rest.
