Ant Exterminator Cost 2026: Standard vs Carpenter Ants
Ant treatment costs $80 to $500, averaging $150 to $250. Carpenter ants cost three times more, and telling them from termites is the distinction that matters.
An ant exterminator costs $80 to $500 with a national average near $150 to $250 for a standard home visit. Carpenter ants cost more, $250 to $500 typically and up to $1,500 for established colonies, because they nest inside structural wood rather than foraging in from outside. Follow-up visits on a maintenance plan run $40 to $70.
Ants are the cheapest common pest to treat and the easiest to misdiagnose. The price gap between a nuisance ant job and a carpenter ant job is threefold or more, and it exists because one is a cleaning problem and the other is a structural one.
What ant treatment costs in 2026
| Service | Cost | Notes |
|---|---|---|
| Standard ant treatment | $80 to $500 | National average around $150 to $250 |
| Initial professional treatment | $150 to $300 | Typical first visit |
| Follow-up maintenance visit | $40 to $70 | On a recurring plan |
| Carpenter ant treatment | $250 to $500 | Standard case |
| Carpenter ant, severe | $250 to $1,500 | Established or hidden colony |
| Structural repair after damage | $200 to $2,000+ | Separate trade, not pest control |

Why carpenter ants cost three times more
Nuisance ants such as odorous house ants and pavement ants nest outside and forage indoors for food. Treatment is a perimeter application plus interior baiting, and the technician is done in well under an hour.
Carpenter ants excavate galleries inside wood to nest. They do not eat it, but they hollow it, and the nest may sit inside a wall void, a window header or a roof structure. Finding it requires inspection rather than spraying, and treatment means reaching a cavity you cannot see. That is technician time, and technician time is what you pay for: payroll is 36% of industry revenue.
The other reason for the price gap is what the finding implies. Carpenter ants are strongly associated with moisture-damaged wood, so an infestation is often a symptom of a leak. A competent inspection says where the moisture is coming from, and fixing that is a separate job.
Carpenter ants or termites: telling them apart
This is the most consequential distinction in the category, because the treatments and the costs differ enormously.
| Feature | Carpenter ants | Termites |
|---|---|---|
| Waist | Narrow, pinched | Straight, no pinch |
| Antennae | Bent, elbowed | Straight, beaded |
| Wings (swarmers) | Front pair longer than rear | Both pairs equal length |
| Relationship to wood | Nest in it, do not eat it | Eat it |
| Debris left behind | Coarse sawdust and insect parts | Mud tubes, no sawdust |
| Typical treatment cost | $250 to $500 | $275 to $1,600 |
If you are seeing swarmers indoors and cannot tell which you have, that is worth a professional inspection before agreeing to any treatment. Termite work is a different service with a different warranty structure, covered in our guide to termite treatment costs.
When a recurring plan makes sense for ants
Ants are the pest most often bundled into a quarterly plan, and for reasonable cause. Nuisance ant pressure is seasonal and recurring, exterior perimeter treatment is quick, and the marginal cost of your stop is low when the technician is already on your street.
- Ask what the plan covers. Many general pest plans include nuisance ants but exclude carpenter ants, which are usually a separate line.
- Compare per-visit, not headline price. A $40 to $70 maintenance visit is not comparable to a $250 one-off.
- Confirm the callback terms if ants return between scheduled visits.
- Get the species identified in writing before accepting a carpenter ant price.
Frequently asked questions
How much does it cost to get rid of ants?
Professional ant treatment costs $80 to $500, with most homeowners paying $150 to $250 for a standard visit. Follow-up visits on a maintenance plan run $40 to $70. Carpenter ants cost more at $250 to $500, rising toward $1,500 for established colonies inside structural wood.
Why is carpenter ant treatment more expensive?
Because carpenter ants nest inside structural wood rather than foraging in from outside, so treatment requires inspection to locate a hidden nest and application into cavities you cannot see. That is technician time, and payroll is 36% of industry revenue. Carpenter ants also often indicate moisture damage needing separate repair.
Do I need pest control for ants or can I do it myself?
Nuisance ants foraging in from outside often respond to retail baits combined with sealing entry points and removing food sources. Carpenter ants generally warrant professional inspection, because the nest is inside the structure and the infestation may indicate a moisture problem. Misidentifying carpenter ants as termites, or the reverse, is common.
Are ants covered by a quarterly pest control plan?
Nuisance ants usually are, since exterior perimeter treatment is quick and fits route work well. Carpenter ants are frequently excluded and priced separately because they require inspection and targeted treatment. Ask which species the plan covers before assuming, and confirm the callback terms between scheduled visits.
