Fire Ant Control

Fire Ant Control: what it covers

Quick answer

Imported red fire ants build dome-shaped mounds in open, sunny ground, and their stings can be painful and in some people dangerous. North Carolina has the species in most of its counties, and Union County appears on the state's quarantine map. Charlotte Pest Control connects Mecklenburg County homeowners with a local technician who maps the mounds and proposes a treatment on site.

A fire ant problem usually shows itself as a loose dome of soil in a lawn, a garden bed or beside a sidewalk. The mound can appear overnight after a rain, and the first contact is often a sting on a bare ankle while mowing or weeding. In Charlotte the imported red fire ant is the species to plan for, and a mound is worth reporting even when it is small.

The imported red fire ant was first recorded in North Carolina in 1952, in nursery stock in Wake and Mecklenburg counties, and it was eradicated there at the time. It has been established in the state since 1957 and is now found in most counties. It favours open, sunny ground and builds its mounds most readily in clay, which is common across the Piedmont.

This page explains how to recognise a mound, why it should be left alone, what a technician maps on a visit and which treatment routes are considered. (855) 974-4733 is the quickest way to ask about a mound that is already causing stings.

How do you tell a fire ant mound from other ant mounds?

A fire ant mound is a loose, dome-shaped pile of soil that often has no visible entrance hole. It is most often built in open, sunny ground and is common in clay. Other ants build mounds too, so an identification is confirmed on the visit rather than by the look of the soil alone.

The mound is loose and rounded, and it can be disturbed easily by a finger. Fresh mounds may appear after rain, and older mounds can flatten or spread over time, so age and position both help.

Stinging is the reason to keep a distance. Workers swarm up quickly from an open mound, and a sting can be painful and can cause an allergic reaction in some people. Anyone who has trouble breathing after a sting should seek emergency care.

Photograph the mound from a safe distance with a coin or a shoe beside it for scale. The image helps the technician plan the visit and records where the mound was found.

  • Keep children and pets away from the mound
  • Photograph it from a distance with a coin for scale
  • Note whether it appeared after a storm

Why should you leave a fire ant mound alone?

Disturbing a mound can bring workers out in numbers and cause stings within seconds. Breaking up a mound also spreads the colony into a wider area and can make it harder to treat. The safest step is to mark the mound, keep people away and let a technician plan the treatment.

A mound is hard to disarm by hand. Digging, flooding or pouring a product onto it without the right product can scatter workers and leave the colony in a new spot.

Mowing and trimming near a mound can disturb it. A marker, such as a flag or a stake placed well outside the mound, reminds the household and the mower operator to keep clear.

Pets are at particular risk because they investigate a mound with their faces. Keep dogs on a lead near the mounds, and call (855) 974-4733 if a pet has been stung several times.

  • Do not dig, flood or stamp on a mound
  • Place a marker so the mower avoids it
  • Keep pets on a lead in the mound area

Does a fire ant treatment need more than one round?

Often it does. Colonies can be large, and a single application may not reach every worker or every nearby mound. A follow-up visit checks for new mounds and for any that survived, and the plan sets when that check happens.

Baits work by being carried back to the colony, and that takes time. Results are judged over a period of weeks, not in the day after the application.

Mounds that appear after a treatment may come from a neighbouring lot or from a colony that was not reached in the first round. The technician notes those locations so the next visit can address them.

Keeping the lawn in good condition helps the result. Dense grass, regular mowing and watering at the right time make a lawn less welcoming for new colonies, though they do not replace the treatment itself.

Warning signs

Signs you need fire ant control

Do not step on, dig into or pour water onto a fire ant mound. Wear closed shoes and long trousers when working in an area with mounds, and keep pets indoors while a treatment is being applied. If a sting causes breathing difficulty, swelling of the face or throat, or a widespread reaction, seek emergency care at once. Call (855) 974-4733 about the mounds themselves.

  • A loose dome of soil, often without a visible hole, in a lawn or garden bed
  • Several new mounds appearing after a heavy rain across the same yard
  • Ants that swarm up quickly and sting when a shoe or a mower disturbs the mound
  • Mounds beside sidewalks, the base of a utility pole or the edge of a driveway
  • Pets or children stung while playing on sunny open ground
  • Mounds that reappear after a single round of household ant spray
Our process

How our fire ant control visit works

  1. Find and map every mound

    The technician walks the lawn, beds, the edges of paths and the strip beside the driveway, marking each mound. Mounds are often found in groups, so the map shows where the colonies sit in relation to the house.

  2. Check the ground and the mound type

    Soil type, sun exposure and how fresh the mound is are recorded. The technician checks whether the mounds are the imported species, because other ant mounds need a different response.

  3. Choose the treatment route

    Baits and mound treatments are the usual options. The choice depends on the number of mounds, where they sit near people and pets, and whether the yard is used for play or for gardening.

  4. Treat and keep people clear

    Treatment is applied to the mounds or the bait is spread across the lawn at the rate set for the product. People and pets are kept away from the treated area until the product has been given time to work.

  5. Follow up on the mounds

    A follow-up visit checks for new mounds and for any that survived. Fire ant colonies can take more than one round, so the plan sets the next check before the technician leaves.

Options

Types and options for fire ant control

Mound treatment

A product is applied directly to individual mounds. It suits a small number of mounds in a yard where the locations are clear and the mounds are away from play areas.

Broadcast bait

Granular bait is spread across the lawn and foraged back to the colony. It is used across a larger area with many mounds, and it asks for care around gardens and pets.

Quarantine and reporting

Union County is on the state's imported fire ant quarantine map, and the state keeps county status under review. Mecklenburg appeared on recent maps as well, but whole-or-partial status is not confirmed here, so a mound is worth reporting either way.

One call and it gets handled.

Most fire ant control calls are scheduled the same day when a technician is free, and you approve the price before any work starts.

Why fire ant control is different in Piedmont

Many yards in Charlotte sit on clay that has been graded and seeded, and that open ground is exactly where a fire ant colony is likely to start. New subdivisions in the outer towns, including parts of Union County, often have bare, sunny edges along the lawn and the driveway, which are the places a mound is first noticed.

The season matters too. Mounds are easiest to spot after rain and in warm, dry weeks when the lawn is open. A regular walk of the lawn in the warm months catches a new mound while it is still small, and a small mound is simpler to plan for.

FAQ

Fire Ant Control FAQs

Are fire ant mounds dangerous?

They can be. Stings are painful and can cause a severe allergic reaction in some people. Keep children and pets away from mounds, and seek emergency care if a sting leads to breathing trouble or swelling of the face or throat.

Can I use a household ant spray on a fire ant mound?

Household sprays often scatter the workers without reaching the colony, which can spread it. A technician chooses a product made for the species and applies it to the right place.

How long does a fire ant treatment take to work?

Baits take time to be carried back to the colony, so results are judged over weeks. The technician sets a follow-up date so new or surviving mounds can be treated in time.

Do I need to report a mound to the state?

Reporting helps the state track the species, and the county's status is under review. Ask the technician whether your county is on the current quarantine map before you move soil, sod or plants off the property.
