Ant Exterminator Cost Calculator (2026)
By Marcus Ellery, Pest Control Editor · Updated July 2026
An ant exterminator costs about $100 to $500 for a one-time treatment, with most homeowners paying around $150 to $300. The big split is the type of ant: common household and odorous ants are a routine job, while carpenter ants — which tunnel into wood and can cause structural damage — run $250 to $500, and more for large or hidden colonies. Home size and whether you go one-time or recurring round out the price. Estimate yours below.

What drives your ant exterminator cost
- Ant type: household and odorous ants are cheap; carpenter ants cost more due to wood damage.
- Colony size: large or satellite colonies hidden in walls need extra visits and drilling.
- Home size: more square footage means more baiting and inspection.
- One-time vs. plan: a quarterly plan ($50–$70/mo) prevents the ants from marching back.
- Access: wall voids, slabs, and crawlspaces raise labor for carpenter-ant jobs.

Ways to save
- Identify the ant first — a household-ant job is a fraction of a carpenter-ant treatment.
- For recurring pressure, a quarterly plan beats repeated one-time calls.
- Wipe trails and remove food and standing water to starve the colony between visits.
- Fix moisture and wood-to-soil contact to keep carpenter ants from returning.
- Get 2–3 quotes; carpenter-ant pricing varies widely with colony depth.

Frequently asked questions
How much does an ant exterminator cost in 2026?
Ant extermination costs about $100–$500 for a one-time treatment, averaging $150–$300. Common household ants are on the low end; carpenter ants run $250–$500 or more because they nest inside wood.
Why do carpenter ants cost more to treat?
Carpenter ants tunnel into structural wood and often have hidden satellite colonies, so treatment needs specialized inspection, wall-void application, and sometimes drilling — pushing costs to $250–$500 and beyond.
Is a one-time ant treatment enough?
For a small, visible trail, one visit may do it. Larger or recurring problems are better handled with a quarterly plan ($50–$70/month), which is often cheaper than repeated one-time treatments.
