If there is wood the termites will find it.
I saw this last year when I had to relocate a HK bed to another area. When I dug everything up I noticed a ton of termites around the the decaying wood. All of my HK beds are a good 100' away from the house but we still have termite protections in place since termites can easily move. We have sentricon tubes installed around the perimeter of our house and shed and our foundation was sprayed with termidor. I don't like using chemicals, but I've seen the damage termites can do and I'm not taking any chances.
