Termite control in Las Vegas means treating an active infestation of western subterranean termites, the valley's main termite. A technician finds the mud tubes and entry route, treats the soil and structure with a liquid termiticide or bait system, and rechecks. Las Vegas Pest Control answers phones 24/7 and confirms the price on site.
The western subterranean termite is the valley's main termite, and it works where you cannot see it. The colony lives in the soil, reaches the house through slab edges, expansion joints and plumbing penetrations, and eats wood from the inside out. By the time a homeowner sees damage, the colony has often been working for a while.
This page is about the case where termites are already there: you found mud tubes, a swarm or damaged wood, and need the colony treated. If you are buying a home and want a written report, that is a termite inspection. If you are pouring a new slab, that is pre-construction treatment. Both are different jobs from the one described here.
They live in the soil and enter through any gap that touches the slab: cracks, expansion joints, plumbing and utility penetrations, and the slab edge against stucco. They also build mud tubes up foundation walls and block cores. A slab does not stop them, it just hides the route.
A slab-on-grade foundation sits directly on soil, which is exactly what termites are looking for. Workers forage through the ground, find a hairline crack or a plumbing sleeve, and slip through. Mud tubes protect them from dry air as they climb.
Many valley homes have decorative rock against the foundation, and irrigation lines buried alongside the slab edge. Moist soil near a sprinkler box or a leaking hose bib gives a colony a reason to stay close to the house, so a technician looks at water as much as at wood.
Swarms are tied to calm, sunny days after the first autumn rains and sometimes spring, and reports run from spring through October. The colonies themselves are active all year. A swarm means a mature colony is near, not that the damage began that day.
Swarmers are the winged termites that leave a colony to start new ones. After they land, they shed their wings, which is why piles of small translucent wings at a window sill are a better clue than the insects themselves. Many people mistake a swarm for flying ants.
Because swarms track the weather, the first autumn rain is a useful reminder to check windows, door tracks and garage corners. If you find wings, collect a few in a clear bag and call. A technician can confirm the species and inspect where they came from.
Not quite. Older slabs in Huntridge or Charleston Heights have decades of settling and original plumbing penetrations, while newer post-tension slabs in Mountain's Edge or Centennial Hills are young but still sit on soil and often face an early inspection. Age changes where a technician looks, not whether termites can get in.
A 1940s Huntridge ranch or a 1950s Charleston Heights tract home has had many seasons for roots, plumbing repairs and soil movement to open paths. Mature trees against the walls and old irrigation also add moisture. The technician pays attention to additions, since a patio slab poured years later can leave a seam.
Newer stucco-and-tile subdivisions are built on slabs that some builders treat before the pour. That can reduce risk for a while, but treatment does not last forever, and soil disturbed by later landscaping or utility work can break the treated zone. Many homes also use post-tension slabs, so a technician locates the cables before drilling anywhere.
Store-bought sprays cannot reach a colony living in the soil under a slab, and spraying a mud tube often just makes the termites build another route. A technician treats the soil zone and entry points, which a homeowner usually cannot do safely or completely.
Termite colonies are hard to eradicate because the workers and the queen are in the ground, away from where you see the damage. A spray that kills what is visible may leave the colony untouched.
There is also a safety question. Drilling a slab without finding post-tension cables, plumbing and electrical lines can cause real damage. This is one of the pest jobs where doing it right is mostly about knowing what is under the concrete.
Do not drill into a slab, pry at mud tubes with chemicals or spray insecticide into walls yourself. Post-tension cables and plumbing can sit under the concrete, and spraying only pushes termites to a new route. Leave the damaged area as it is and call a technician.
The technician inspects the slab edge, garage, plumbing penetrations, expansion joints, wood trim and any wood-to-soil contact. Confirming it is a western subterranean termite and not another wood pest decides the treatment.
Termites reach slab homes through cracks, cold joints and utility penetrations, and by building mud tubes up foundation walls. Mapping those routes tells the technician where to treat and where to look again later.
A liquid termiticide is applied in a trench beside the foundation or injected through drilled holes in slabs and block cores, creating a treated zone the colony has to cross. In some cases a bait system is added.
Infested wood that can be reached may be treated directly. Heavily damaged framing is a repair job for a carpenter, and the technician will tell you where that line is.
A later visit looks for fresh mud tubes and new activity. Colonies are active all year, so follow-up and an annual check matter more than a single application.
A termiticide applied in a trench around the foundation and injected under slabs forms a treated barrier. It is the most common choice for a slab home with a known entry point, and it usually works quickly once the soil zone is continuous.
Stations installed around the property hold slow-acting bait that workers carry back to the colony. They suit homes where trenching is hard, such as around pools, planters, hardscape and tight lot lines, and they need regular checks.
Targeted treatment of accessible infested wood, such as trim and a sill plate, supports soil treatment instead of replacing it. It is used when the damage is limited and the colony has been addressed in the ground.
These are typical estimates, not a quote from Las Vegas Pest Control. Only one termite figure has a source, and it is a guide figure for liquid treatment in general, so treat it as a rough benchmark.
| Job | Typical range | What it includes |
|---|---|---|
| Liquid termite treatment | $3–$5 per linear foot | a published guide figure; actual jobs vary with the slab, access and the product |
| Whole-home termite treatment total | Confirmed on site | depends on the home's perimeter, how many slab penetrations need drilling and whether baits are added |
| Bait station system | Confirmed on site | depends on lot layout, how many stations and how often they are monitored |
| Drilling and treating slab or block cores | Confirmed on site | patio, garage and interior slab sections are priced by what the technician finds |
| Wood repair after treatment | Confirmed on site | a carpenter's job, quoted separately from termite treatment |

Termite pressure here is a soil-and-slab story. The western subterranean termite is the valley's main termite, colonies are active all year, and swarms tied to autumn rains make September through October a good time to look at window sills and garage corners. That is different from regions where Formosan or eastern termites drive the calls.
Housing age shapes the visit. In Huntridge and Charleston Heights the concern is decades of slab and plumbing wear. In Green Valley Ranch and Craig Ranch the slabs are 15 to 30 years old, so homes often come up for termite checks during sales. In Mountain's Edge, young slabs on disturbed desert get early inspections.
A technician will often ask where irrigation lines and sprinkler boxes run, whether planters touch the stucco, and whether wood is in contact with soil. Those details matter more than the age of the house.

General pest service in Las Vegas starts at about $72 a visit, based on one local company's advertised starting price.
Las Vegas has pests in every month, but the mix follows the heat.
Yes.
A monsoon storm leaves standing water, wet soil and displaced insects.
Termites have two pairs of wings of equal length, a thick waist and straight antennae. Flying ants have a narrow waist, bent antennae and uneven wings. A technician can tell for sure from a few specimens, so save some in a bag.
Many soil treatments are done in a day or less, depending on the perimeter and slab access. Baits take longer to work and need monitoring. Your technician gives a plan and a follow-up schedule after the inspection.
Ask the technician what rechecks are included before you approve the work, and get any terms in writing. Do not assume that a treatment covers future damage or a future colony. Colonies are active all year, so an annual look is sensible.
Termiticides are applied in soil and structural voids following the product label. Your technician explains what to keep clear, how long to stay off treated ground and when it is safe to return. Follow those instructions closely.
Yes. The colony lives in the soil beneath and beside the slab and enters through cracks, joints and utility openings. That is why treatment often means drilling the slab and treating the soil along the foundation.
If you have seen active signs, you likely need treatment. If you are buying or want to know the condition of the home, a termite inspection gives you a written report first.
