Scottsdale's dry reputation can make termites feel like someone else's problem, but desert subterranean and drywood termites are both found in the Phoenix area. The irrigated landscapes of golf communities, courtyard fountains and well-watered gardens turn parts of the city into pockets of moisture, and the warm climate means termites rarely get a long break.
Two termite groups to understand
- Desert subterranean termites forage underground in search of cellulose, building tubes that are thin and easy to miss. They enter through slab cracks, expansion joints and stucco contact points.
- Drywood termites live inside sound, dry wood such as roof framing, fascia, patio covers and furniture. They leave behind tiny hard pellets in small piles.
Subterranean colonies need soil contact, while drywood colonies do not, so inspection and treatment strategies differ.
Where Scottsdale homes can be vulnerable
Many properties have extensive stucco, which can hide termite tubes and feeding behind the surface. Wooden pergolas, ramadas, trellises and exposed beams are popular design features and give termites plenty of surfaces. Landscape timbers and railroad ties in garden beds, and wooden fence posts set in soil, bridge directly to the house. In older areas near Old Town and south Scottsdale, wood-framed construction and original fascia boards can be well past their prime. Upscale desert homes often have tile roofs with wood decking beneath, where drywood termites quietly feed.
Signs to watch for
- Small piles of pellets below window frames, beams or patio covers.
- Winged termites or loose wings around lights after rain.
- Mud tubes on foundation walls or along the underside of slabs.
- Hollow-sounding wood or bubbling paint.
- Soft spots in fascia or trim near sprinkler spray.
Inspection and treatment on the Arizona side
Inspectors check the roof edges, attic framing, garage, patios and the stucco-to-slab junction. A subterranean treatment can involve trenching and drilling to place termiticide in soil beneath slabs and patios, or installing bait stations. For drywood termites, the choices are localized treatment in small areas or whole-structure fumigation or heat when the infestation is widespread. The provider should explain the species found, how far the infestation extends and what each option involves, including preparation and when it is safe to re-enter the home.
Steps to lower risk
- Keep irrigation off the stucco and away from the slab edge.
- Replace weathered fascia and sealed wood on pergolas promptly.
- Do not bury wood in landscaping or let it touch soil.
- Seal roof gaps and cracks where winged termites can enter.
- Schedule routine inspections, especially for larger or older properties.

Fumigation planning
If a Scottsdale home needs tent fumigation, plan for several days away. Pets, plants, food and medications need to leave the property or be sealed in special bags according to the provider's instructions. Residents of attached or multi-unit properties may need to coordinate with neighbors and the homeowners association.
Termite FAQ
Can termites survive Scottsdale's summer heat?
Yes. Subterranean colonies stay underground, and drywood colonies live inside wood where temperatures are moderated.
Are pergolas and patio covers at risk?
Yes. Exposed wood with soil contact or cracks can host both termite types.
Does stucco stop termites?
No. It can actually conceal their activity.
How often should I have an inspection?
Many professionals suggest yearly checks, particularly for homes with wood features or past activity.
