Extermco publishes its prices because Fort Smith and Northwest Arkansas homeowners deserve a straight answer before a technician ever pulls into the driveway. Every number on this page is the same number our office quotes on the phone and the same number our technicians carry in the truck.
Residential prices are set by the size of your home in four tiers: under 2,000 square feet, 2,000 to 2,999, 3,000 to 3,999, and 4,000 to 4,999. Homes over 5,000 square feet are quoted individually. Yard services are priced by lot size. Prices are current for 2026, apply across Arkansas, Oklahoma, and Missouri, and do not include sales tax.
General Pest Control Prices by Home Size
| Service | Under 2,000 sq ft | 2,000–2,999 | 3,000–3,999 | 4,000–4,999 |
|---|---|---|---|---|
| Quarterly pest control, billed monthly | $35/mo | $45/mo | $55/mo | $65/mo |
| Quarterly pest control, billed per visit | $125 | $150 | $165 | $185 |
| One-time pest service (general pests, fleas, wasps, scorpions) | $165 | $180 | $195 | $215 |
The quarterly plan treats the interior and exterior every 90 days for ants, spiders, roaches, wasps, scorpions, and the other common pests active in Arkansas homes. If pests come back between quarterly visits, we come back at no charge. On a one-time service, a second visit within 14 days is free.
Specialty Program Prices by Home Size
| Service | Under 2,000 sq ft | 2,000–2,999 | 3,000–3,999 | 4,000–4,999 |
|---|---|---|---|---|
| German roach cleanout, all 3 visits | $300 | $330 | $365 | $400 |
| Brown recluse, initial treatment | $350 | $400 | $500 | $600 |
| Brown recluse, monthly follow-up (3 months) | $100/mo | $125/mo | $150/mo | $175/mo |
| Bed bugs | From $250 per room, quoted after free inspection | |||
| Wildlife removal | $300 trap setup for 5 days, then $75 per animal after the first | |||
| Rodent control | Quoted after free on-site inspection | |||
The roach cleanout is three visits: an initial cleanout, then two bait services 14 days apart, paid once at the first visit. It is the treatment for an established German cockroach infestation, meaning you are seeing ten or more roaches during the day. The brown recluse program uses liquid, dust, and attic fogging on the first visit, then monthly inspection and re-treatment until glue board monitors show the population is gone. Fort Smith and the River Valley are among the heaviest brown recluse areas in the country, and standard quarterly spraying does not reach where they live. Bed bug pricing depends on how many rooms are affected; we inspect first, at no charge, and quote per room in writing.
Yard Treatment Prices by Lot Size
| Service | Up to ¼ acre | ¼–½ acre | ½–¾ acre | ¾–1 acre |
|---|---|---|---|---|
| Ticks and fleas | $175 | $290 | $385 | $500 |
| Army worms | $175 | $290 | $385 | $500 |
| Cicada killers | $175 | $290 | $385 | $500 |
| Fire ants (River Valley only) | $220 | $365 | $480 | $625 |
| Hornets and yellow jackets | $300 | $300 | $300 | $300 |
Add a yard treatment to your quarterly plan and save 35 percent on the yard price. Add one to a one-time service and save 20 percent. Fire ant treatment is offered in Fort Smith and the River Valley only; fire ants are not established in Benton and Washington Counties, so NWA homes do not need it. Mosquito control is quoted by property after a free inspection.
Termite Treatment and Warranty Prices
Fort Smith sits in USDA Termite Zone 1, the highest-risk zone in the country, and eastern subterranean termites are active in Sebastian County every month of the year. Extermco has treated termites here since 1991. Termite treatment is priced from the linear footage of your foundation, measured from the county assessor sketch, and quoted in writing after a free on-site inspection. No two foundations are the same, so we do not publish a flat treatment price; we inspect, measure, and put the number in writing before any work starts. Read about liquid and bait treatment methods. Check our current deals for the Trelona installation offer.
| Service | Under 2,000 sq ft | 2,000–2,999 | 3,000–3,999 | 4,000–4,999 |
|---|---|---|---|---|
| Liquid termite treatment | Quoted in writing after free inspection | |||
| Trelona bait system installation | Quoted in writing after free inspection | |||
| Annual warranty renewal, liquid treatment | $165 | $200 | $225 | $250 |
| Annual renewal, bait system | $225 | $250 | $300 | $400 |
| Booster re-treatment (every 5–10 years) | 3 times the annual renewal, charged at our cost in place of that year's renewal | |||
| New construction pretreat (homeowner) | 15 cents per square foot of slab | |||
| WDI-R inspection and report, OK and MO | $175 flat | |||
| Termite clearance letter, Arkansas | NPMA-33 issued with treatment, no standalone inspection charge | |||
A termite inspection for treatment is always free. For a real estate closing, a standalone WDI-R inspection and report is a flat $175 in Oklahoma and Missouri. Arkansas does not use a standalone inspection; the NPMA-33 termite clearance letter is issued with treatment. The annual renewal keeps your full warranty active. The liquid barrier breaks down over 5 to 10 years, and when it does we re-apply it at cost rather than charging for a new treatment. Renewal statements go out by mail about a month before your expiration date.
No Contracts. Cancel Any Time. No Fees.
Extermco does not use contracts. Our service agreements are simply a schedule, and you can cancel at any time, for any reason, with no cancellation fee and no penalty. We have run the company this way since 1991 because we would rather earn your business every quarter than lock you into it. If a company in Fort Smith or Northwest Arkansas is quoting you a lower monthly rate, ask them what it costs to leave. Then ask them how many times you have to call to do it.
What Backs the Price
Extermco carries $3 million in total liability insurance. Our full termite warranty covers the cost of any retreatment plus repair of new termite damage up to $50,000, and the warranty transfers to the next owner if you sell the home. We are licensed in Arkansas, Oklahoma, and Missouri, family-owned, and based in Fort Smith with a second office in Springdale. You can check our work against 616 Google reviews averaging 4.9 stars.
How Our Prices Compare
Most pest control companies serving Fort Smith and NWA do not publish prices at all. The ones that do usually publish a monthly rate tied to a 12-month agreement with a cancellation fee that equals the discount you received for signing. National chains offer a free inspection and then price the treatment on site. Extermco's pricing is published by home size, it is the same on the phone as it is here, and it does not require you to sign anything you cannot walk away from.
