I have wood flooring glued on a slab. Presently there are termites under neath the flooring. Can any one tell me how long it might take for temites to have eaten some of the boards? I live in SC and have termite protection, but in April of this year we had termites in another part of the house,(window sill). The termite company came and treated all around the house except the back of the house. Which is now where the termites have eaten under the wood floor.
