My suggestion is to bury LARGE chunks of solid oak all along your foundation
that will give them something to eat other than your foundation. Make sure
the chunks are no smaller than 10 inches as that is the area that termites
Live breed and die in, they "never " venture further than 10" from their
place of birth. Also, make sure you remove any trace of rock or cement from
around the the chunks of oak as this is just like handing them a free meal
as they love to eat anything made from aggregate.
