In Cincinnati and Northern Kentucky we have a large amount of wood frame built houses, many with basements. The basement keeps the ground warm below the frost line in the winter time, allowing termites to stay active through the cold winters. Many of the houses in the Greater Cincinnati region were built in the first half of the 20th century, on block foundations. These foundations almost always shift, separate, and allow water and soil entry conducive to termite infestation. A completely sealed and crack free basement is the only cure for preventing termites.
