An ant exterminator costs $250 per visit on average, with most homeowners paying $200 to $300, according to Angi.1 HomeAdvisor publishes a $150 average within an $80 to $500 range for a single treatment.2 Fixr publishes a $250 average for general ant treatment of a 2,000 sq. ft. house, excluding fire and carpenter ants.3 Prices below are national averages*.

*National averages, not local quotes. Angi figures are from a guide updated September 2026, HomeAdvisor figures from a guide updated June 2026, and Fixr figures are from a guide last updated August 2022. Your price depends on ant species, infestation severity, treatment method, and home size.

Safety note: the treatments priced below involve pesticides. The National Pesticide Information Center advises anyone considering pesticide use to try a lower-toxicity product first and to always read and follow all label instructions carefully.4

What the sources say

Source Headline figures Notes
Angi (updated Sep 2026) $250 average per visit; most pay $200 – $300 Fumigation $1,300 – $4,000; specialty treatments $250 – $500
HomeAdvisor (updated Jun 2026) $150 average; $80 – $500 range for a single treatment Corporate sibling of Angi – where their figures match, matching alone doesn’t establish independent corroboration
Fixr (updated Aug 2022) $250 average for general treatment of a 2,000 sq. ft. house excluding fire and carpenter ants; range $200 – $300; low $150 (general treatment, under 2,000 sq. ft.); high $1,200 (carpenter ant treatment and remediation, over 3,000 sq. ft.) Separately published, no shared sourcing stated

The three headline sets differ and are presented as published, with no conclusion about why they differ. Angi and HomeAdvisor are corporate siblings; Fixr’s guide is older (August 2022) and its figures are labeled to that date throughout.

Cost by treatment method

Method Angi (2026) HomeAdvisor (2026) Fixr (2022)
Baiting / poisoned bait $120 – $200 $100 – $220 (poison treatment) $120 – $200
Barrier spray $80 – $150 $80 – $150 $80 – $120
Mound treatment (fire ants) $100 – $250 $100 – $150 —
Two-step method $500 – $1,000 $500 – $1,000 $600 – $900
Fumigation (whole home) $1,300 – $4,000 $1,300 – $4,000 $1,700 – $3,150 (2,000 sq. ft. property)
Specialty (fire or carpenter ants) $250 – $500 not listed not listed

Baiting matches between Angi and Fixr, and barrier spray and two-step figures match between the sibling pair (matching figures alone don’t establish independent corroboration). Fumigation spans differ between the sibling pair and Fixr and are presented as published.

Cost by infestation level

Level Angi (2026) HomeAdvisor (2026) Fixr (2022)
Small $150 – $300 $150 – $300 $150 – $300
Medium / moderate $300 – $700 (moderate) $300 – $500 $300 – $500
Large included in moderate above $400 – $700 $400 – $700
Severe $800 – $1,400 $800 – $1,400 $800 – $1,200

Small-infestation figures match across all three publishers; the severe row matches only within the sibling pair. Angi groups medium and large into one moderate tier.

Cost by ant type

Carpenter ants $250 – $500 $250 – $500

Other common ants (odorous house, thief, rover) around $150 $150 – $250 depending on species

Carpenter, fire, and pharaoh figures match across the two separately published pages (no shared sourcing stated). The sugar and Argentine rows differ and are presented as published. Fixr also prices less common species: rover, field, and grease ants at $150 to $160; acrobat, citronella, pavement, moisture, and odorous house ants at $200 to $250; and Allegheny mound, ghost, and harvester ants at $250 to $300.3
