Two years ago I had more firewood than would fit under my shed so I
bought 2 PT 4x4x8's from Lowes, laid them on the ground, stacked the
firewood on them, and covered the wood with a tarp. I just used the
last of the wood (all good BTW) and went to move the 4x4's. They were
eaten up and rotted from the ground side up. Termite tunnels were
readily apparent.
Two years on the ground, not in it, and they were completely useless!
They still had the tags stapled on the ends so the staples didn't even
have time to rust off. I knew it wouldn't last as long as the old PT
lumber, but not even 2 years??

Apparently the change in pressure treating chemicals to less toxic
materials might be the problem. Also may be a good idea to kill those
termites before they start munching on your house
