Dome mounds appear in sunny lawn areas
Mounds are a classic sign, but similar ants exist; disturbance response matters.

Yard fire ants
What should you do about fire ants?
Fire-ant mounds in lawns and play areas are a medical and yard-management issue: treat stings and allergic reactions first, keep children and pets away from active mounds, and do not kick mounds open barefoot. Note mound locations and whether ants are aggressive when disturbed.
Yard treatments work best when they match the species and cover foraging areas as directed on labels—not when random products are dumped on one mound. If mounds keep returning, if a sensitive household needs a plan, or if identification is uncertain, request a written outdoor treatment scope with pet and play-area precautions.
Put safety before diagnosisSeek emergency care for severe allergic reactions to stings. Keep people and pets off treated areas for label-required intervals. Do not use indoor products outdoors or vice versa off-label.

U.S. national guidance
What changes after you choose a location?
Choose a state to make the geographic boundary explicit.
A ZIP helps identify possible pest-service areas and current buyer coverage, but it does not prove jurisdiction, address-level coverage or an available qualified pest-management professional.
Applies nationallyThe safety and observation sequence on this page is general U.S. guidance.
Must be confirmed locallyPest identity, pesticide rules, applicator licensing, rental responsibility, prices, residential new-service eligibility, commercial or mobile-home eligibility, provider coverage and address-level serviceability require current evidence for the exact property.
Separate identification, exposure and property conditions
Which situation best matches the home?
Children or pets use the same yard zones
Exposure risk raises urgency for a controlled plan.
Notice next: Note play equipment and pet paths near mounds.
Mounds reappear after rain or mowing
Weather and soil disturbance can change visible mound counts.
Notice next: Track whether new mounds are new colonies or rebuilt soil.
Safe observation
What should you record before the call?
A short, factual description helps the next professional choose the right first inspection without treating a symptom as proof.
Mound counts help planning; they cannot prove species everywhere or guarantee a sting-free yard.
What to record
- Mound map and how ants react when disturbed from a safe distance.
- Sting incidents and whether medical care was needed.
- Prior yard products and dates.
- Water features, gardens and neighboring untreated lots.
Stop and get appropriate help
- Severe allergic reaction, difficulty breathing or widespread symptoms after stings.
- Mounds are in areas where unsafe application would hit water, gardens or play equipment without precautions.
- A proposal cannot explain treated zones and re-entry guidance.
Short answers
Questions people ask before the call
Should I pour boiling water on every mound?
It can be hazardous and incomplete. Ask about methods that match labels and yard use.
Do fire ants mean I must treat the whole neighborhood?
Your lot plan still matters; untreated neighbors can affect pressure. Ask what a realistic property-level scope includes.
Can this page confirm my ant is a fire ant?
No. Aggressive mound ants need local identification when treatment decisions depend on species.
