Agree, moisture (South of 44 has a lot of ponds and literally filled in swamp area). Wooden houses are optimal restaurants for termites. Three months was all it too to devour an exterior grade 2 x 4 frame I had once at at FL residence on the ground in the back yard.

Definitely a good idea to have a plan one way or another to prevent and protect from termites. They can penitrate through cement and can get through cracks of cement as well.
