Pre-Construction Termite Treatment

The pre-construction termite treatment is also referred to as a “Pre-Treat”. Most new structures in the United States are treated against termites during the initial construction process.  In many communities, it’s actually required under law.

There are many methods to treatment.  The most conventional is a liquid treatment application forming a continuous chemical barrier in the soil around both sides of a foundation.  For houses with crawlspaces, the soil around the piers that will support the floor system is also treated (as shown in the image at the right). This barrier should prevent foraging termites from reaching the foundation and piers and, ultimately, the wood in your house.

For slab construction (including foundations, patios and garages), the entire soil (or gravel) surface is treated before the vapor barrier is installed and the slab poured over it. These treatments typically require in excess of 100 gallons (depending on the size of the house) so it is not a task that most homeowners can do on their own.
