The BEST solution is to have an experienced professional trench, as needed, around the house where the stucco terminates below grade. Have them neatly cut the stucco 4-6 inches above ground level and remove it from the foundation. They should then seal the bottom of the cut to the foundation with adhesive basecoat, making it impossible for termites to re-enter. The exposed foundation can then be refinished and/or painted below the cut to match the house if the homeowner requests it.

Many homes finished with siding have foam insulation board applied below the siding for insulation, moisture-barrier, to cover imperfections in the poured concrete slab and to build out an "un-square" foundation. This foam also terminates below ground level. This invites termites, undetected from the outside and protected from predators, to freely eat into the wood of the home.

Foam and outer coatings should be removed by an experienced professional down to the foundation, up to the siding level and below ground level. This removes termites' tunnel system and they will no longer be able to reach the wood to freely feed on it undetected. The residue should then be removed and, if preferred by the homeowner, the exposed foundation slab can be re-coated and/or painted to match the siding or house trim.
