Many Tempe residents assume termites are a humid-climate problem. They are not. Subterranean termites are widespread across the Phoenix valley, living in the soil beneath landscaping, irrigated lawns and even bare dirt where moisture collects. If you have noticed mud tubes, swarming insects or damaged wood, call (844) 725-1661. PestMinistry is a referral service that connects you with an independent, licensed provider who inspects and treats.
How termites live in the desert
Desert subterranean termites tend to nest deeper in the soil and travel farther to find moisture. That means they rely on irrigation, leaky pipes and the damp soil near planter beds and swimming pools. Dry-looking yards can hide a lot of activity just a few inches below the surface. Drywood termites also occur in Arizona, particularly in dry wood such as attic framing and furniture, though they are less common than subterranean species in the Tempe area.
Signs to watch for
- Mud tubes, pencil-thin, climbing a foundation wall or stucco crack.
- Winged termites emerging, often after the first monsoon rains of summer.
- Discarded wings piled on window sills or near light fixtures.
- Baseboards or door frames that sound hollow, or stucco that is bubbling.
- Small kick-out holes with pellets, a clue for drywood termites.
Why Tempe houses can be at risk
Slab-on-grade foundations are the norm. Termites can enter through cracks in the slab as thin as a sheet of paper, expansion joints, and the openings around plumbing lines. Stucco that extends below ground level hides tubes from view. Older neighborhoods such as the Lakes, Holdeman and areas near Papago Park have decades of landscaping growth, buried wood and irrigation, all of which attract termites. Block fences with wood posts and wood patio covers are also a place to check.
What inspection and treatment involve
- Inspection: a licensed inspector checks the slab perimeter, garage, attic, patio structures and landscape for signs of activity and conducive conditions.
- Treatment choice: liquid soil treatment to form a barrier, bait stations, or both.
- Drilling and injection: for slab areas or hardscape, the provider may treat through small holes in concrete.
- Spot treatment for drywood termites: foam or liquid injection, or whole-structure options for widespread cases.
- Documentation: a written report of findings and a recommendation for repair.
Real estate transactions in Arizona commonly involve a wood-destroying insect inspection, so buyers and sellers in Tempe often come across termite findings during escrow.
Habits that lower the risk
- Keep irrigation emitters and sprinkler heads from spraying the foundation.
- Remove tree stumps, old railroad ties and buried scrap lumber.
- Keep wood piles and wood mulch off the house.
- Repair leaks promptly, including swamp cooler and pool equipment plumbing.
- Schedule periodic inspections, especially for older homes.
Pools, patios and block walls
Tempe backyards are full of wood features that sit close to damp ground: ramadas, pergolas, gate posts and fence rails. Check where posts meet soil or concrete, and watch for mud on the underside of patio covers. A provider will usually include these structures in an inspection, and sealing or replacing contact points can be the difference between a recurring problem and a resolved one.
Tempe termite questions
When do termites swarm in Tempe?
Many people see swarms around summer monsoon storms, though timing varies by species.
Can I tell if the termites are subterranean or drywood?
Mud tubes suggest subterranean; pellets suggest drywood. A provider can confirm, which matters because the treatment is different.
Does concrete protect my home?
No. Termites exploit small slab cracks and expansion joints to reach the framing above.
How often should I have the home checked?
Annual inspections are a common recommendation, especially for older homes and those with a history of activity.
