Sounds like a good kind of problem to have.

I stopped putting firewood on pallets. It creates the perfect habitat for deer mice, which then hanta-poo all through my woodpile. Bleah. Now I just throw junk wood at the bottom and pack it tight. No real problems, but we may be drier than you.

Call up a big box appliance store. All those stoves and fridges and washers and dryers are shipped with a basic pallet underneath. Offer to recycle them provided they reimburse you for gas. (Hey, nothing ventured ...)
