We used some treated wood in other areas around the house and termites did eat it. That is why whatever we use if it's wood, we will need to wrap the plastic around it so the termites will have less access to it. Maybe termites did not eat the old style treated wood, but they eat this new stuff. We have termites so very bad. This is some we had in wood we had stored under out deck, it was raised up off the ground and only there for a few months and they ate it, they ate most of the deck (which was treated and painted) back bathroom wall and the sill plate of the kitchen before we bought the house. Even ate the paper off the back of the sheetrock. Even though we have had them treated by pest control, we cannot get rid of them. Trying to work on shedding water away from the house better, re sloping soil around the house, going to put a vapor barrier under crawl space too this summer when it dries out under there.
