People moving to Arizona from wetter states often assume the dry climate protects houses from termites. In Gilbert, that assumption can be costly. Both subterranean and drywood termites live in the Phoenix metro area, and a typical Gilbert home provides everything they want: wood framing, irrigated soil and plenty of undisturbed corners.
Two termite types, two ways in
Desert subterranean termites nest in the soil and reach the structure through mud tubes or cracks in the slab. In Gilbert, canal-fed irrigation, drip systems and leaky pool plumbing make the ground damp enough for them. They are especially active after monsoon rains, when swarmers take flight.
Drywood termites do not need soil contact at all. A queen can start a colony in a single fascia board, eave or attic rafter, and the colony can grow for years unseen. They may arrive in furniture, picture frames or firewood. Unlike Gulf Coast cities, Formosan termites are not the typical threat here, so Gilbert inspections focus on these two groups.
How the signs show up in Gilbert homes
- Pellet-like frass, a mound of tiny ridged granules resembling coarse sand, below a window or in the attic.
- Pencil-sized mud tubes on stem walls, garage slabs and around plumbing pipes.
- Swarms around windows and light fixtures, followed by scattered wings.
- Blistered paint, a hollow sound when tapping wood trim, or doors that begin to stick.
Stucco exteriors and tile roofs hide a lot. Eaves and gable ends on tile roofs sit exposed to the sun but protected from weather, a popular spot for drywood colonies. Block walls separating yards are often fine themselves but may have wooden gates, trellises and fence posts that are in direct soil contact.
Inspection and treatment options
Licensed inspectors examine the attic, eaves, garage, slab perimeter and any wood in contact with soil. They use tapping, probing and sometimes moisture meters or thermal tools to find hidden activity. Subterranean treatment normally involves a liquid barrier in a trench along the foundation, or a bait system installed around the property. Drywood treatment depends on the extent: spot treatment where activity is localized, or full structure fumigation under a tent when colonies are widespread. Your provider should explain their choice, outline preparations such as moving pets and plants, and describe any post-treatment checks.
Reducing risk in the desert
- Aim drip lines and sprinklers away from the stem wall.
- Keep wooden structures such as gates, pergolas and sheds painted and off the soil.
- Fix swamp cooler or air conditioner condensate leaks.
- Store firewood away from the house and avoid bringing in used wood furniture without checking it.
- Have the home inspected before buying, especially resale houses with older patios or additions.

Termite FAQ for Gilbert owners
Do I need fumigation if I find a few pellets?
Not necessarily. Small, accessible infestations can sometimes be treated locally, but an inspector must judge the extent first.
Are newer Gilbert homes safe?
Newer construction may include pre-treatment, but protection can fade, and drywood termites can still fly in.
When do swarms happen?
Subterranean swarms often follow monsoon rain; drywood swarms may occur in late summer and fall.
Will termites damage a stucco house?
Stucco is not food, but the wood framing behind it is, and termites can work out of sight for a long time.
