Virginia code requires a termite pre-treatment to be done for new construction of homes and additions. Most lenders for home mortgages will also want proof that the home has been pretreated for termites before they issue a home loan.

Typical Types of Construction

  • Slab foundation: meaning the home was built on a concrete slab and there is no access to the underside of the home.
  • Crawlspace foundation: meaning the home has been elevated on foundation block allowing access to the underside of the home. Typically a snug fit, thus the name, where one would have to crawl to fit under their home.

Virginia recognizes four types of termite pre-treatments to satisfy code requirements:

  1. Soil poisoning – consists of treating the soil under and around the home, dirt filled porches and under concrete slabs such as garages
  2. Wood/Framing treatment – consists of treating wood framing and other wood components a minimum of 24 inches up from these components being on contact with the ground
  3. Bait system installations – consists of canisters placed around the home 15-20 feet apart that would intercept foraging termites. The canisters have product in them laced with various types of termiticides depending on which manufacturer is chosen
  4. Physical barrier system – newly added to Virginia code. National Exterminating does not recommend this method of treatment to control termites in Tidewater, Hampton Roads, and Southside Virginia.
