If you are building a home you should treat the ground before any footings or slabs are poured. This is because you will never have the opportunity again to treat underneath slabs. When treating these areas, you are supposed to apply 1 gallon of
Termidor per 10 square feet. Treat all areas that will have a slab poured including basements, patios, porches, and garage slabs. Then, when the house is completed and all grade levels have been placed next to the house, you should do a 6 inch trench and treat around the home as well. This is the proper way to treat a new construction home.
