It is fair to wonder how termites survive in a place that receives only a few inches of rain a year. The answer is moisture that people supply. Henderson's irrigated landscapes, pool decks, leaking sprinkler lines and shaded planters create damp pockets in the soil, and subterranean termites thrive underneath them. Many residents are surprised to learn termites are one of the valley's quiet property threats.
Termites of the Mojave
The main wood-destroying insects around Henderson are subterranean termites, including desert species that forage at night and in cooler hours, nesting deep in the ground and seeking moisture. Colonies are generally smaller than those of southern humid climates, and they often swarm after summer monsoon storms. Drywood termites occur in parts of the Southwest and are sometimes introduced in furniture or lumber, so inspectors check for both. Formosan termites are not established in southern Nevada.
How Henderson homes expose themselves
Most houses here are built on concrete slabs, with stucco finishes that extend close to the ground. Stucco can conceal mud tubes, and a stucco weep screed that touches soil or landscaping rock offers termites a hidden entrance. Slab penetrations for plumbing, cracks from soil movement, and expansion joints are other points of entry. Wood in contact with soil, such as pergolas, fence posts, patio covers and planters, is vulnerable. Communities near Lake Las Vegas and those with extensive lawn and drip irrigation provide steady moisture. Older homes in the Water Street District and near Boulder Highway may have different foundations that call for closer inspection.
Signs to take seriously
- Winged termites swarming near windows or door frames after a storm.
- Mud tubes along block walls, behind landscape timbers or inside the garage.
- Bubbling or blistering of paint on trim near the ground.
- Hollow-sounding wood in patio covers, fences and door frames.
- Small piles of wings on window sills or in spider webs.
Inspection and treatment
An inspector examines the slab perimeter, garage, attic, sprinkler zones and any wood-to-soil contact, using a moisture meter and probe. Treatments may include liquid soil applications along foundations, drilled injections under slabs and patios, and bait stations in landscaped areas. Because stucco and rock mulch can hide activity, providers often pull rock back from the foundation to inspect. Drywood termites in attic wood or patio covers may be treated locally or, in larger infestations, with whole-structure options.
Prevention in a desert setting
- Pull river rock and mulch back from the stucco weep screed.
- Repair broken drip lines and aim sprinklers away from walls.
- Replace wood posts set in soil with metal brackets or concrete footings.
- Avoid storing lumber, cardboard or firewood against exterior walls.
- Schedule a termite inspection every year or two, especially before selling.

Ask them to explain what they find in terms of species and moisture sources.
Do termites exist in the Las Vegas Valley?
Yes. Subterranean termites live in valley soils and are more likely where irrigation and moisture are available.
Can stucco hide termite damage?
It can. Termites sometimes build tubes behind stucco, which is why inspectors look at weep screeds and interior walls.
How do I know if swarmers are termites or ants?
Termites have equal-length wings, straight antennae and a thick waist. Ants have a pinched waist and elbowed antennae.
Does extreme heat kill termites?
Surface heat does not reach the colony, which stays underground in cooler, moist soil.
