In Tucson, termites are a quiet and constant threat. The desert may look inhospitable, but two groups of termites thrive here: subterranean termites that nest in the soil near irrigated landscaping and leaking plumbing, and drywood termites that live entirely inside dry wood and need no contact with the ground. The mix of historic adobe and brick homes in Armory Park and Barrio Viejo, 1950s ranch houses near Fort Lowell and the University, and stucco subdivisions on the northwest and east sides means both types find suitable homes.

Subterranean versus drywood
Desert subterranean termites live in colonies underground and build mud tubes to reach wood. They are drawn to places where soil stays damp, such as around sprinkler lines, air-conditioner condensate drains and cracked plumbing. Drywood termites fly into attic vents, eaves and wooden furniture, then establish small colonies inside the wood. They leave tiny, hard, sand-like pellets (frass) that fall from kick-out holes. Swarms of subterranean termites often follow monsoon rains, while drywood termites tend to swarm in the warmer months.
Signs to look for
- Mud tubes on stucco, block walls or foundation edges.
- Small piles of pellets beneath window sills, in garages or on attic insulation.
- Discarded wings after a storm.
- Hollow-sounding wood trim, doors or furniture.
- Bubbling or cracked paint over wood surfaces.
Tucson housing details that matter
Stucco often runs right to the ground, hiding termite tubes behind the finish. Adobe homes rely on wood lintels, vigas and door frames, which can be attacked. Slab-on-grade homes have plumbing and electrical penetrations that provide a path from soil to framing. Wood fascia, eaves and patio covers are exposed to drywood termite flights. Over time, patio additions and outbuildings extend the surface area available. A thorough inspection includes the attic and roofline as well as the base of the walls.
Treatment choices
- For subterranean termites: soil treatment around the foundation or bait stations, with drilling through patios or garage slabs where needed.
- For drywood termites: localized foam or liquid treatment of infested wood, or whole-structure options such as fumigation or heat for widespread activity.
- Moisture correction, including sprinkler adjustments and leak repairs.
- Follow-up inspections to verify results and watch for new activity.
Ask your provider how they determine which type you have, because treatment for one does not cure the other.
Simple prevention steps
- Keep irrigation and drip lines away from walls.
- Screen attic and eave vents with fine mesh.
- Seal and paint exposed wood, including patio covers and fascia.
- Do not store firewood or lumber against walls.
- Arrange periodic inspections, especially for older homes.

Tucson termite FAQs
Can I have termites without any contact with soil?
Yes. Drywood termites live inside the wood itself and do not need the ground.
Does stucco protect against termites?
No. It can hide activity, and termites may travel behind or through cracks in it.
Do termites swarm during monsoon season?
Subterranean termites often do, usually after rain. A swarm indoors is a reason for inspection.
Is fumigation always needed for drywood termites?
No. Small, accessible infestations can sometimes be treated locally. The provider will advise.
