What types of termites are found in Arizona?

Arizona has three main termite species: subterranean termites (the most destructive), drywood termites, and dampwood termites. Desert subterranean termites are especially aggressive and widespread throughout the state.

How do I know if I have termites in my Arizona home?

Signs include mud tubes on foundation walls, hollow-sounding wood, discarded wings near windows, frass (termite droppings) that look like sawdust, and bubbling or uneven paint on walls.

When is termite season in Arizona?

Termite swarms in Arizona typically occur from March through June and again after monsoon rains in July and August. However, subterranean termites are active year-round underground.

How much does termite treatment cost in Arizona?

Costs vary by treatment type and home size. Liquid soil treatments typically range from $500 to $2,500. Fumigation for drywood termites can cost $1,500 to $5,000 or more. Get multiple quotes and ask about warranties.

What is the best termite treatment for Arizona homes?

For subterranean termites, liquid termiticide barriers or bait station systems are most effective. For drywood termites, localized treatments or whole-house fumigation may be required depending on the extent of infestation.

How long does termite treatment last?

Liquid termiticide treatments typically last 5-10 years. Bait station systems require ongoing monitoring. Annual inspections are recommended regardless of treatment type to catch new activity early.

Can I prevent termites in Arizona?

Reduce wood-to-soil contact around your home, fix moisture problems, keep mulch away from the foundation, store firewood off the ground, and schedule annual termite inspections — especially before buying a home.

Termite Control in Arizona: Protecting Your Home from Silent Destroyers

Arizona is one of the most termite-active states in the country, with subterranean termites (Reticulitermes and Heterotermes species) present in virtually every county. Subterranean termites live in underground colonies of up to one million workers and build mud tubes to travel from soil to wood. They consume wood 24 hours a day, 365 days a year, and a mature colony can cause significant structural damage before any visible signs appear. Arizona also has drywood termites (Incisitermes minor) in some areas, which nest inside the wood itself and do not require soil contact — these require different treatment methods than subterranean species.

Termite control in Arizona typically involves one of three approaches: liquid soil treatment (termiticide barrier), termite bait systems, or fumigation. Liquid treatment involves trenching around the foundation and injecting termiticide into the soil to create a continuous chemical barrier — this is the most common method for subterranean termites. Bait systems use in-ground stations with cellulose bait that workers carry back to the colony, eventually eliminating it. Fumigation (tenting) is reserved for severe drywood termite infestations and involves sealing the structure and introducing a gas fumigant. Annual termite inspections are strongly recommended for all Arizona homeowners.

Signs of termite activity include mud tubes on foundation walls or in crawl spaces, hollow-sounding wood when tapped, discarded wings near windows and doors (from termite swarms), and frass (termite droppings) that looks like sawdust or coffee grounds. Termite swarms in Arizona typically occur in spring and after monsoon rains.
