Arkansas has a wide variety of ant species â and the treatment that works for one often won't work for another. Our technicians identify the exact species before any treatment begins. Here's what we commonly encounter in the Fort Smith and Northwest Arkansas area:
Red Imported Fire Ant
One of the most aggressive ant species in Arkansas. Fire ants build large mounds in yards and open areas and will swarm and sting repeatedly when disturbed. Their stings cause painful burning welts and can trigger serious allergic reactions. A major concern for children, pets, and anyone working outdoors.
Carpenter Ant
One of the largest ant species in the region. Carpenter ants don't eat wood â they excavate it to build galleries for nesting, causing serious structural damage over time. Often confused with termites. Most active at night, they prefer moist or decaying wood in walls, attics, and around windows.
Odorous House Ant
Named for the rotten coconut smell they produce when crushed. One of the most common ant calls we get across Fort Smith and NWA. These small brown ants form massive colonies with multiple queens, making them very difficult to control without professional treatment. They're relentless foragers in kitchens and pantries.
Pharaoh Ant
Tiny, pale yellow ants that are notorious for being nearly impossible to control with sprays. When threatened, Pharaoh ant colonies "bud" â splitting into multiple new colonies and spreading throughout a structure. They thrive in heated buildings and are a serious problem in hospitals, restaurants, and apartment complexes.
Crazy Ant
Named for their erratic, rapid movement. Crazy ants form massive super-colonies and are attracted to electrical equipment â they can short-circuit AC units, junction boxes, and appliances. They're highly resistant to standard pesticides and require specialized treatment approaches.
Acrobat Ant
Named for their ability to raise their abdomen over their thorax when disturbed. Acrobat ants nest in decaying wood and foam insulation and often enter homes through damaged wood or utility penetrations. They can strip insulation from wiring and occasionally sting.
Pavement Ant
Small brown ants that nest under sidewalks, driveways, and building foundations â pushing up small dirt mounds through cracks in concrete. They commonly forage indoors for sweets and greasy foods. Their colonies can number in the thousands and spread quickly under slabs.
Argentine Ant
Argentine ants form massive interconnected super-colonies that can span entire neighborhoods. They're aggressive toward other ant species and rapidly displace native ants. They forage indoors heavily during hot dry weather and after heavy rains, making them a persistent seasonal nuisance.
Harvester Ant
Large reddish-brown ants that build prominent mounds in open, dry areas. Harvester ants clear vegetation around their mounds and deliver a painful sting. They're most common in drier areas of the River Valley and can damage lawns, gardens, and pastures.

ðĻ Why Species Identification Matters
This is where most DIY treatments fail. Using the wrong product for the wrong species doesn't just fail to solve the problem â it can make it significantly worse:
- Pharaoh ants and crazy ants will "bud" when treated with repellent sprays â splitting into new colonies and spreading the infestation further through your home
- Carpenter ants require treatments that reach the satellite colonies inside wall voids â surface sprays only kill foragers
- Fire ant mounds require direct mound treatment plus a yard-wide barrier â treating one mound just moves the colony
- Odorous house ants have multiple queens and require bait that gets transferred back to the colony â spray kills only workers
ð Serving Both Fort Smith & NWA
Ant species and pressure vary across the region. Our two local offices give us deep familiarity with what's active in your specific area at any given time of year.
Fort Smith & River Valley
Fire ants are a major problem across Sebastian and Crawford Counties â especially in open yards, pastures, and along roadsides. Carpenter ants are common in older homes near wooded areas. Odorous house ants are the top indoor ant call we get throughout the River Valley.

Serving: Fort Smith, Van Buren, Alma, Greenwood, Barling, and the River Valley
Springdale & Northwest Arkansas
The wooded terrain and rapid residential development across Washington and Benton Counties creates constant ant pressure. Odorous house ants, carpenter ants, and fire ants are the most common calls from Springdale, Fayetteville, Rogers, and Bentonville. Crazy ants have become an increasing concern in NWA in recent years.

ð ïļ Our Ant Control Process
Effective ant control starts with identifying the species â then targeting the colony, not just the workers you can see:
- Free Inspection: We identify the ant species, locate trails and entry points, and find nesting areas inside and outside your home. Different species nest in very different places.
- Custom Treatment Plan: We select the right treatment for your specific species â bait, non-repellent spray, mound treatment, or a combination â and explain exactly what we're doing and why.
- Interior Treatment: We treat entry points, trails, and harborage areas inside the home using targeted methods that reach the colony rather than just repelling foragers.
- Exterior Perimeter Treatment: We treat the foundation, entry points, and yard to create a barrier and eliminate outdoor colonies before they move inside.
- Follow-Up: Many ant species â especially odorous house ants and pharaoh ants â require follow-up treatments as bait works through the colony. We return to confirm full elimination.

Ant Control FAQs â Arkansas Homeowners Ask
Why do I keep getting ants even after spraying?
Most over-the-counter ant sprays are repellents â they kill the foragers you can see but don't reach the colony. The colony survives, sends out new workers, and the problem returns within days. Professional treatment uses non-repellent products and baits that foragers carry back to eliminate the queen and the entire colony.
How do I know if I have carpenter ants or termites?
Both are wood-damaging pests but they look and behave differently. Carpenter ants are larger, black or reddish-black, and have a pinched waist. They excavate smooth galleries in wood rather than eating it. Termites are smaller, pale, and eat the wood itself. If you're not sure, our free inspection will identify exactly what you're dealing with.
Are fire ant treatments safe for my yard, kids, and pets?
Yes. Extermco uses EPA-approved fire ant treatments including baits and mound drenches that are safe for lawns once dry. We'll give you clear re-entry instructions so your family and pets know exactly when it's safe to use the yard again.
Why are ants worse after it rains?
Heavy rain floods underground ant colonies, forcing them to relocate or move to higher ground â which often means inside your home. This is especially common with odorous house ants and pavement ants. A perimeter treatment applied before rainy season significantly reduces this problem.
How many treatments does it take to get rid of ants?
It depends on the species and the size of the colony. Some infestations resolve after a single treatment. Others â especially odorous house ants, pharaoh ants, and crazy ants â require 2â3 treatments as bait works through the colony over several weeks. We'll set realistic expectations at the time of inspection.
Do you treat ants in both Fort Smith and Springdale?
Yes. We have licensed technicians based out of both our Fort Smith and Springdale locations. Whether you're in the River Valley or anywhere across the NWA corridor â Fayetteville, Rogers, Bentonville, Centerton â we have a local team ready to help.
