Most newcomers to Arizona assume a desert is too dry for termites. Glendale proves otherwise. Desert subterranean termites tunnel deep to find moisture, then forage through the soil toward wood, while drywood termites need nothing but dry lumber. Add landscape irrigation, block-wall fences and the sharp humidity jump of monsoon season, and the West Valley becomes a steady source of termite calls.
Two main groups
- Desert subterranean termites live in soil colonies and travel up foundation walls or through cracks in the slab. They build mud tubes, though these can be thin and easily overlooked.
- Drywood termites live inside the wood they eat, such as eaves, rafters and wood furniture. Evidence is small, hard pellets that look like grains of sand or coarse salt.
Formosan termites are a southeastern species and not a Glendale concern.
Where termites find an opening
Stucco is not a barrier to termites. They can hide behind it, in the gap between the stucco and the foundation plate, called the weep screed area, or travel up inside the wall unseen. Slab foundations offer cracks and plumbing penetrations. Wood fascia, patio covers and fences touching the ground make convenient bridges, and landscape timbers or wooden planter boxes beside the house are common culprits. Glendale's older neighborhoods around Catlin Court and the downtown core feature smaller houses with more exposed wood than recent subdivisions.
Warning signs worth a closer look
- Winged termites near windows or lights, often after the first rains of monsoon.
- Mud tubes on stem walls, inside garages or on the underside of patio covers.
- Small piles of pellets below eaves, window sills or wooden furniture.
- Bubbling paint or a hollow sound when tapping baseboards.
- Doors or windows that begin to stick.
How termite work is done on desert homes
An inspector walks the slab perimeter, checks the attic, tests wood with a probe and may use moisture meters. Subterranean treatment usually involves trenching and treating soil around the foundation, drilling through patios and garage slabs where needed, and sometimes installing bait stations. For drywood termites, providers might treat individual galleries with foam or liquid, or recommend tent fumigation when infestations are spread across the attic. Findings drive the recommendation, so request a written explanation of what was found and where.
Protect the structure
- Fix irrigation leaks and broken drip lines near the house.
- Keep wood and mulch off stucco and foundation edges.
- Replace rotted fascia or window trim promptly.
- Avoid attaching wood fences directly to the house.
- Schedule regular inspections, especially for older properties.

Buying or selling a Glendale home
Arizona real estate transactions often involve a wood-destroying insect inspection. If one shows past or current activity, ask for documentation on treatment type and date. A provider can also explain whether any damage looks active or old.
Termite FAQ
Can termites survive the Arizona heat?
Yes. They live underground or inside wood where temperatures are moderate.
Is my stucco house safe from termites?
No. Stucco does not stop them, and they can hide behind it.
Are flying termites in my house an emergency?
Swarmers indicate a mature colony nearby. A prompt inspection is wise.
Does the dry climate slow damage?
Damage may be slower in dry wood, but irrigation and leaks create moisture that speeds it.
