How to Prevent Termites in Nevada Homes: A Las Vegas Homeowner's Checklist
Most people assume termites are a problem for humid places like Florida or the Gulf Coast. Then they buy a home in Las Vegas, get their first termite inspection report, and find out otherwise.
Southern Nevada has active subterranean termites, including the desert subterranean termite. They live in the soil, travel through mud tubes, and feed on the wood inside your walls, often for years before anyone notices. Our dry climate doesn't keep them away. It pushes them toward the few places that stay damp: around your foundation, under your drip lines, and along your plumbing.
We're Aspire Pest & Termite Control, a family-owned, licensed termite company (Nevada Department of Agriculture license #7115) serving Las Vegas, Henderson, North Las Vegas, and Summerlin. Termite treatment is what we do every day. Here's the checklist we'd give our own family for keeping termites out of a Nevada home.
Why termites show up in desert homes
Termites need three things: food (wood and other cellulose), moisture, and shelter (EPA). In Las Vegas, wood is everywhere inside the house, and the soil provides shelter. Moisture is the part you control, and it's the reason prevention works.
Most valley homes are built on a concrete slab. Subterranean termites can squeeze through cracks as thin as a business card, and they commonly come up through:
Expansion joints and cracks in the slab
Gaps around plumbing that passes through the slab (tub drains, toilet lines, water heater lines)
The bottom edge of stucco walls where soil, gravel, or landscaping touches the stucco
Wood patio covers, fences, and planter boxes that sit on or in the dirt
1) Control moisture around your foundation (the biggest lever)
In a desert, the damp spots around your house are termite magnets. Start here.
Check your drip irrigation. Emitters placed right against the foundation keep the soil wet next to your slab all summer. Move them out 12 to 18 inches, and fix leaking lines.
Aim sprinklers away from walls. Overspray that hits stucco every morning keeps the base of the wall wet.
Watch your A/C condensate line. In a Las Vegas summer, that little pipe can drip for hours a day. Make sure it drains away from the house, not into the soil beside the slab.
Fix plumbing leaks fast. Slow leaks under sinks, at the water heater, or at hose bibs create exactly the conditions termites look for (University of Kentucky Entomology).
Keep the ground sloped away from the house. After a monsoon storm, water should run away from your foundation, not pool against it.
2) Keep soil and wood from touching
Subterranean termites travel from the soil into wood. Every spot where they touch is a bridge (UC IPM).
Keep the bottom of your stucco visible. There should be a few inches of clearance between the soil or rock and the bottom edge of the stucco (the weep screed). When landscapers pile gravel or dirt above that line, termites can travel up behind the stucco where you'll never see them.
Don't stack firewood, lumber, or old pallets against the house.
Lift wood off the ground. Fence posts, patio cover posts, raised garden beds, and planter boxes should sit on concrete footings or metal brackets, not buried in dirt.
Use treated or termite-resistant lumber for anything built outdoors near soil.
3) Remove termite "highways" near the house
Clear wood scraps, dead roots, and old tree stumps near the foundation. Stumps left in the yard after a tree removal are a common feeding site.
Go easy on wood mulch near the walls. Mulch holds moisture and gives termites cover. Decorative rock is a better choice right next to the foundation.
Keep shrubs trimmed back from the walls so you can see the base of the house and air can move.
4) Inspect your home a few times a year
Termite damage is usually hidden, so the goal is to catch signs early (EPA). Walk your home in the spring and again after the summer monsoon rains and look for:
Mud tubes: pencil-width tunnels of dirt running up the foundation, stucco, garage walls, or inside cabinets.
Swarmers and discarded wings: small winged insects near windows, doors, or light fixtures, or piles of tiny wings on window sills. Swarms in Southern Nevada often follow warm weather and rain.
Damaged wood or drywall: baseboards that sound hollow, bubbling paint, or small pinholes in drywall.
Problem spots: the garage (where the slab meets the wall), under the kitchen and bathroom sinks, around the water heater, and around door frames.
If you see any of these, don't spray it and hope. Store-bought sprays can kill the termites you see while the colony keeps feeding. Call a licensed professional for an inspection.
5) Consider a preventative termite treatment
If you're buying a home, have had termites before, or live in a neighborhood where termites are common, a professional treatment is the most reliable long-term protection.
At Aspire, we specialize in liquid barrier termite treatments for subterranean termites. We apply a termiticide into the soil around the foundation and at key entry points, such as slab penetrations and expansion joints, creating a treated zone termites can't safely cross. Every treatment follows the product label and Nevada regulations, which is what the EPA and the Nevada Department of Agriculture require of licensed applicators (EPA termiticide labeling).
Our treatments come with a warranty: 5 years on a full termite treatment and 3 years on an exterior treatment, so you're covered long after we leave.
Whoever you hire, make sure they're licensed by the Nevada Department of Agriculture. You can ask for their license number and verify it.
Your "do this weekend" termite plan
Walk around the outside of the house. Mark any spot where water pools, sprinklers hit the wall, or drip emitters sit against the foundation.
Check that you can see the bottom edge of the stucco all the way around. Pull back rock or soil where you can't.
Look under sinks and around the water heater for leaks or dampness.
Move firewood, lumber, and wood debris away from the house.
Check garage walls and the base of the stucco for mud tubes.
Frequently asked questions
Do termites really live in Las Vegas?
Yes. Southern Nevada has active subterranean termite populations, including the desert subterranean termite. Termite inspections are a routine part of many Las Vegas home sales for this reason.
When do termites swarm in Las Vegas?
Swarms commonly happen in spring and during or after summer monsoon rains, when warm, humid conditions follow a storm. Seeing swarmers inside the house is a strong sign of an active colony nearby.
Can I prevent termites on my own?
You can make your home far less attractive to termites by controlling moisture and removing wood-to-soil contact. These steps lower your risk, but they don't guarantee protection. If termites are already present, or you want long-term protection, a licensed treatment is the most reliable option.
Do I need a termite inspection when buying a home in Nevada?
Many lenders and buyers request one. A wood-destroying insect (WDI) inspection tells you whether there's active activity or past damage before you close. At Aspire, WDI report inspections start at $80, and inspections are free if you think you already have termites.
What's the difference between prevention and treatment?
Prevention is about removing the conditions termites need: moisture, wood contact, and cover. Treatment is what a licensed professional does to eliminate an existing colony or create a protective barrier around the home.
Does Aspire offer a termite warranty?
Yes. Aspire Pest & Termite Control provides a 5-year warranty on full termite treatments and a 3-year warranty on exterior termite treatments.
