⚠️ Fort Smith Is in Termite Zone 1 — The Highest Risk Designation in the Country: The USDA classifies Sebastian County as a Termite Infestation Probability Zone 1. This means Fort Smith and the surrounding River Valley face the maximum level of subterranean termite risk. Eastern subterranean termites are active in this area year-round and cause damage that standard homeowners insurance almost never covers.

Termite Treatments We Offer

Every home and every infestation is different. Extermco offers the full range of professional termite treatments so we can recommend the right solution for your specific situation rather than a one-size-fits-all approach:

💧 Termidor Liquid Soil Treatment

Termidor is the most widely used professional liquid termiticide in the United States and consistently ranks as the most effective product available for subterranean termite control. We apply Termidor to the soil around and under your foundation, creating a treated zone that kills termites on contact and transfers the active ingredient through the colony through termite-to-termite contact. Termidor treatments stop active infestations fast and provide long-lasting protection for your home's structure. This is the right choice when you have active termite activity causing ongoing damage.

🎯 Trelona Bait Station Installation

Trelona is a BASF professional-grade termite baiting system that eliminates termite colonies at the source rather than just creating a barrier. Stations are installed in the soil around your home's perimeter. Worker termites find the bait during natural foraging, feed on it, and share it with the colony — reaching queens that would never be exposed to a surface treatment. Trelona uses novaluron, an insect growth regulator that targets the molting process. No drilling into your foundation. No broad chemical application. Just targeted colony elimination. Ask about our current $100 off Trelona installation offer.

📊 Trelona Monitoring Program

Once Trelona stations are installed, they function as a permanent early warning system for your home. Our technicians inspect every station on a regular service schedule, checking for new termite activity and replacing bait as needed. If termites appear in any station we know immediately — before they reach your home's wood. This ongoing monitoring is what turns a one-time treatment into continuous, reliable protection year after year.

📋 NPMA-33 Real Estate Inspections

If you are buying or selling a home in Arkansas, your lender or contract almost certainly requires an NPMA-33 Wood Destroying Insect inspection. Arkansas law requires more than just the form — a valid clearance package must include the NPMA-33 report, a signed 12-month termite contract, and a property diagram. Many out-of-state lenders do not know this. Extermco provides complete, fully Arkansas-compliant WDI inspection packages for real estate transactions throughout Fort Smith, NWA, and eastern Oklahoma. We do it right the first time so your closing stays on track.

🛡 Our Termite Repair Warranty

Extermco stands behind our termite treatments with a repair warranty. If termites cause new damage to your home after our treatment, we cover the repairs. This is the difference between a company that treats and walks away and one that takes responsibility for the results. Ask us for full warranty details during your free inspection.

⚠️ Warning Signs of Termite Activity

Termites work silently inside your walls, floors, and foundation for months or years before most homeowners notice anything. These are the signs to watch for — and if you see any of them, call us immediately for a free inspection:

🪲

Mud Tubes

Pencil-sized tunnels of soil on foundation walls, piers, or exterior surfaces — the most reliable indicator of subterranean termite activity

🪰

Swarmers

Winged termites emerging indoors or outdoors in spring — indicates a mature colony is nearby and has been present for years

🪶

Discarded Wings

Small piles of wings near windows, doors, and light fixtures after a swarm event — swarmers shed wings after pairing

🪵

Hollow Wood

Baseboards, door frames, or floor joists that sound hollow when tapped — termites eat from the inside out leaving a thin outer shell

🚪

Tight Doors & Windows

Doors and windows that suddenly stick or are hard to open — termite damage warps wood framing around openings

🟤

Frass

Small piles of wood-colored pellets resembling sawdust near wood surfaces — termite excrement pushed out of galleries

Why Fort Smith and NWA Are High-Risk Termite Markets

Arkansas is one of the most termite-active states in the country and Fort Smith sits in the worst of it. Several factors combine to make this one of the most challenging termite markets in the South:

USDA Zone 1 Classification

The United States Department of Agriculture classifies the termite risk across the country into probability zones. Fort Smith and Sebastian County fall in Zone 1 — the highest risk designation possible. This classification is based on soil conditions, climate, and historical termite activity data. It means subterranean termites are not just present here — they are highly active and highly destructive year-round.

Year-Round Activity

In colder climates termite activity slows significantly in winter. In Fort Smith's climate, Eastern subterranean termites remain active throughout the year. There is no safe season when your home is protected by inactivity. Protection needs to be continuous.

Older Construction Vulnerability

Fort Smith's historic neighborhoods — particularly around the Garrison Avenue corridor, downtown, and older residential areas — feature construction styles with pier and beam foundations, wood subfloors, and crawl spaces that give termites direct wood-to-soil contact. These homes have often gone decades without professional termite inspection and many have existing damage that has never been identified.

NWA New Construction Risk

Many homeowners in Bentonville, Fayetteville, Rogers, and Springdale assume new construction means no termite risk. That is not accurate. New construction disturbs established termite colonies in the soil and wood-to-soil contact during the building process creates termite access points that can go undetected for years. Benton and Washington Counties see consistent termite activity and new construction requires the same level of protection as older homes.

Termidor vs. Trelona — Which Treatment Is Right for Your Home?

Both Termidor and Trelona are highly effective professional termite treatments. The right choice depends on your situation:

Factor	Termidor Liquid Treatment	Trelona Bait Stations
How it works	Creates treated soil zone around foundation	Bait carried back to colony by workers
Speed of action	Fast — stops active damage quickly	Slower — works over weeks as bait spreads
Colony elimination	Kills termites in treated zone	Eliminates entire colony including queens
Foundation drilling	Required for slab homes	No drilling required
Ongoing monitoring	Periodic retreatment as product degrades	Permanent monitoring station network
Chemical use	Broader soil application	Minimal — contained in stations
Best for	Active infestations needing fast results	Long-term protection and prevention

For homes with active infestations causing ongoing structural damage, Termidor is often the right first step. For long-term protection and colony elimination, Trelona is the gold standard. In some cases we recommend both — Termidor to stop active damage quickly followed by Trelona installation for permanent monitoring and colony elimination. We will give you an honest recommendation based on what we find during your inspection.

Our Termite Inspection and Treatment Process

Free Comprehensive Inspection: We inspect your entire home inside and out — foundation, crawl space, attic, all accessible wood framing, and the soil conditions around your perimeter. We look for active termite activity, past damage, mud tubes, conducive conditions, and entry points. We never recommend treatment without first understanding exactly what we are dealing with.
Honest Assessment and Recommendation: We walk you through exactly what we found, where the risk or activity is located, how extensive any damage appears to be, and what treatment approach we recommend and why. No pressure, no scare tactics — just a clear, honest picture of your home's termite status.
Treatment: Whether we are applying Termidor to the soil, installing Trelona bait stations, or both, our licensed technicians perform every treatment according to manufacturer specifications and Arkansas Department of Agriculture standards. Documentation is provided for every treatment performed.
Monitoring and Follow-Up: For Trelona installations we schedule regular monitoring visits to inspect every station. For liquid treatments we schedule follow-up inspections to confirm the treatment is performing as expected. You are never left wondering whether your home is protected.
NPMA-33 Documentation: For real estate transactions we provide the complete Arkansas-compliant package — the NPMA-33 form, the required 12-month service contract, and the property diagram. Everything your lender and title company need, done correctly the first time.

Termite Control FAQs — Fort Smith and NWA Homeowners Ask

How do I know if I have termites?

The most reliable signs are mud tubes on your foundation or interior walls, swarming winged termites in spring, discarded wings near windows and light fixtures, wood that sounds hollow when tapped, and doors or windows that suddenly stick due to warped framing. Many termite infestations produce no visible signs at all until significant damage has already occurred, which is why annual professional inspections are recommended for all Fort Smith and NWA homes.

Does homeowners insurance cover termite damage?

Almost never. Standard homeowners insurance policies classify termite damage as a preventable maintenance issue rather than an unforeseeable event and exclude it from coverage. This is one of the most important reasons to invest in professional termite protection — the cost of annual monitoring is a fraction of the cost of uninsured structural repairs.

How much does termite treatment cost in Fort Smith?

The cost depends on your home's size, the type of treatment, and whether there is an active infestation requiring immediate treatment or whether you are installing preventative protection. Extermco always provides a free inspection and a clear quote before any work begins. We do not charge inspection fees and we do not pressure you into services you do not need. Ask about our current $100 off Trelona installation offer.

How long does a Termidor treatment last?

Termidor treatments typically provide effective protection for five years or more when properly applied. Over time the active ingredient naturally degrades in the soil. We schedule follow-up inspections to monitor the treatment's effectiveness and advise you when retreatment may be appropriate based on the conditions at your property.

Is termite treatment safe for my family and pets?

Yes, when applied correctly by a licensed professional. Both Termidor and Trelona are EPA-approved products. Termidor is applied to the soil around and under your foundation — not broadcast inside your home. Trelona is contained within sealed bait stations. Our technicians follow all label requirements and will give you specific re-entry guidance for your household including any pets.

My home is only a few years old. Do I still need termite protection?

Yes. New construction is not termite-proof. Eastern subterranean termites will attack any accessible wood regardless of the home's age. New construction in Fort Smith and NWA often disturbs established termite colonies in the soil during the building process and wood-to-soil contact during construction creates access points that termites find and exploit. We inspect and treat new construction throughout our service area every week.

Do you provide termite inspections for real estate closings?

Yes. Extermco provides complete Arkansas-compliant NPMA-33 inspection packages including the WDI report, the required 12-month service contract, and the property diagram. We serve buyers, sellers, lenders, and real estate agents throughout Fort Smith, NWA, and eastern Oklahoma. Call us as early in the contract period as possible — last-minute inspection requests during closing week create unnecessary pressure for everyone involved.
