Ant Exterminator Cost in Dallas: 2026 Price Guide
Last updated: March 5, 2026
Ant exterminator cost in Dallas ranges from $100 to $450, with the average homeowner paying around $200. Dallas deals with heavy ant pressure from multiple species, with fire ants infesting virtually every yard in the DFW metro. Carpenter ants damage wood in older homes, and invasive crazy ants are spreading into the area. Quarterly plans are the standard recommendation for ongoing prevention.
This guide covers ant treatment pricing specific to the Dallas-Fort Worth metro. For national pricing, see our ant exterminator cost guide. For general pest control in the area, see our Dallas pest control cost guide.

| Individual mound treatment | $8 – $15/mound | $8 – $15/mound | Per-mound pricing for small infestations |
| Carpenter ant treatment | $200 – $450 | $250 – $500 | Nest location + targeted treatment |
| Quarterly plan | $100 – $175/qtr | $100 – $175/qtr | Perimeter spray + interior as needed |
Fire Ants: DFW's Biggest Ant Problem
Fire ants (Solenopsis invicta) infest virtually every yard in the Dallas-Fort Worth metro. They are aggressive, deliver painful stings, and are especially dangerous to children and pets. Fire ant mounds appear in lawns, garden beds, along sidewalks, and near foundations.
Professional fire ant treatment uses two approaches:
- Broadcast bait treatment ($150 to $350). A granular bait is spread across the entire yard. Worker ants carry the bait back to the colony, killing the queen and collapsing the mound over 2 to 4 weeks. This is the most effective approach because it treats colonies you cannot see.
- Individual mound treatment ($8 to $15 per mound). Each visible mound is treated directly with a liquid drench or granular product. This is faster but misses hidden colonies and new mounds that form from untreated colonies nearby.
Fire ant reinfestation is inevitable in DFW. Colonies from neighboring properties, parks, and vacant lots will recolonize a treated yard within months. Ongoing quarterly treatment is the only way to maintain a fire ant-free yard.
Carpenter Ants in Dallas
Carpenter ants damage wood structures by excavating galleries for nesting. In Dallas, they are most commonly found in older homes near moisture sources: around leaking plumbing, in wood-to-soil contact areas, near roof leaks, and in homes near White Rock Lake and East Dallas where mature trees provide nesting habitat.
Carpenter ant treatment costs $200 to $450 and includes locating the nest, applying targeted insecticide (often a combination of bait, liquid spray, and dust), and recommending moisture repairs to eliminate the conditions that attracted them. For more detail, see our carpenter ant treatment cost guide.
Crazy Ants in DFW
Rasberry crazy ants (tawny crazy ants) are an invasive species spreading into the Dallas-Fort Worth metro from Southeast Texas. They form massive colonies numbering in the billions, move erratically (hence the name), and are attracted to electrical equipment where they cause short circuits in AC units, electrical panels, and irrigation controllers.
Crazy ants are particularly difficult to control because they do not respond to traditional bait products and their colony structure makes elimination nearly impossible. Professional treatment focuses on population suppression through direct chemical application and perimeter barriers. Treatment costs $150 to $400 depending on the scope of the infestation.
Seasonal Ant Activity in Dallas
Ant activity in Dallas follows a seasonal pattern:
- Spring (March through May). Peak fire ant activity as colonies expand after winter. Mound building is most visible. Indoor ant invasions increase as colonies forage aggressively.
- Summer (June through August). Fire ants move deeper underground during extreme heat. Activity shifts to early morning and evening. Indoor invasions often increase as ants seek water and cooler environments.
- Fall (September through November). Second peak in fire ant activity as colonies prepare for winter. New mounds appear rapidly. This is an important time for treatment.
- Winter (December through February). Activity slows during cold snaps but fire ants do not die off in the DFW climate. Colonies remain active underground on warmer days.
What Affects Ant Treatment Cost in Dallas
- Ant species. Fire ant yard treatment and carpenter ant structural treatment cost more than general household ant control.
- Yard size. Broadcast fire ant treatment is priced based on yard area. Half-acre lots cost more than standard quarter-acre lots.
- Infestation severity. A few ant trails in the kitchen cost less than a yard full of fire ant mounds or an active carpenter ant colony in the wall.
- Home age and condition. Older homes with moisture issues attract more carpenter ants and may need remediation beyond just pest treatment.
