In Arizona, termite bonds are strongly recommended for most homeowners — not just an optional add-on. The state has one of the highest subterranean termite pressures in the country, with Heterotermes aureus and other desert species active year-round in the warm Sonoran Desert climate. Understanding what a termite bond actually covers helps you make an informed decision.

A termite bond is a service contract between you and a licensed pest control company that covers ongoing termite prevention and, in most cases, retreatment if an infestation occurs. Some bonds also include repair coverage for damage that develops during the contract period, though this varies significantly between companies and contract tiers.

There are two main types: a subterranean termite soil treatment with an annual inspection warranty, and a baiting system with ongoing monitoring. Soil treatments create a chemical barrier in the soil around the foundation; baiting systems use in-ground stations to intercept termite foragers before they reach the structure.

Annual bond fees typically run $150 to $350 per year depending on the size of your home and the type of treatment. Initial treatment for a new bond on an untreated home runs $700 to $1,500 for a standard single-family residence. Retreatment is generally included at no additional charge under most bond agreements.

If you're buying a home, a termite inspection — called a Wood Destroying Organism (WDO) report in Arizona — is essential before closing. Many lenders require it. If active termites or prior damage is found, the seller typically funds the treatment, and you should negotiate to have the bond transferred or a new one established at closing.

For existing homeowners without a bond, the question is whether your home has been treated previously and how long ago. Soil treatments have a service life — most companies recommend renewal every 5 to 7 years in Arizona's climate. A professional inspection will tell you whether active activity is present and whether your existing treatment is still providing adequate protection.

The cost of a termite bond is modest compared to the cost of repairing termite damage, which can run $3,000 to $15,000 or more depending on what's been damaged. In Arizona's climate, a termite bond is one of the most cost-effective forms of home protection available.
