Red ants in Virginia are not one species, so finding reddish ants or a soil mound in your yard does not automatically mean you have fire ants. Red imported fire ants, Solenopsis invicta, are present in Virginia, and the state’s imported fire ant quarantine now includes Chesterfield County. Other ants can be mistaken for them, which makes identification the first step before treatment. This guide explains how to recognize suspected red ants in Virginia, where imported fire ants are regulated, what to know about their stings, and what to do when a suspicious colony appears around your home.
Are Red Ants in Virginia Always Fire Ants?
Red ants in Virginia are not automatically red imported fire ants. Color is only one identification clue, and even imported fire ants can range from reddish-brown to darker brown depending on the type and genetics. Virginia Tech also warns that other ants found in the state can build mounds or sting and may be mistaken for imported fire ants.
That is why size, body structure, nest location, and behavior need to be considered together. GreenShield’s guide to different types of ants shows how much ant species can differ in their appearance and nesting habits. Treating based only on color can mean targeting the wrong pest while the actual colony remains active.
Red Imported Fire Ants Have Several Identifying Features
According to Virginia Tech’s guidance on imported fire ants, imported fire ant workers vary in size within the colony. They have a two-node waist, antennae with 10 segments ending in a two-segmented club, and a visible stinger at the tip of the abdomen. Those small body details are useful for a trained identification, but they can be difficult to confirm accurately while ants are moving across a lawn.
Behavior can provide another clue, but homeowners should not disturb a mound to test it. Imported fire ants defend their colony quickly when disturbed, and large numbers of workers may respond at once. If you see reddish-brown ants around a mound, note the location and activity instead of kicking, digging into, or otherwise disturbing the nest.
How to Identify Imported Fire Ants Around Your Home
Fire ant identification becomes easier when you look at several clues instead of relying on one feature. Imported fire ants favor open, sunny areas and may nest in lawns, flower beds, parks, drainage areas, along concrete, and near building foundations. Virginia Tech also notes that colonies can occur around electrical housings and other structures.
Their mounds do not all look alike. Virginia Tech reports that imported fire ant mounds can range from nearly flat to 18 to 24 inches tall, depending in part on colony age and soil conditions. A low area of loose soil can therefore deserve just as much attention as a taller, more obvious mound.
| What You Notice | Why It May Point to Imported Fire Ants | What to Keep in Mind |
|---|---|---|
| Reddish-brown ants | Red imported fire ants commonly have reddish-brown coloring | Color alone cannot confirm the species |
| Workers of different sizes | Imported fire ant colonies contain workers that vary in size | Close examination is usually needed |
| A mound in open, sunny soil | Lawns, landscape beds, and sunny ground are common nesting areas | Mounds can vary greatly in size and shape |
| Fast defensive activity | Imported fire ants respond aggressively when a colony is disturbed | Do not disturb a mound simply to test this behavior |
| Activity near concrete or foundations | Fire ants may nest near sidewalks, buildings, and other warm structures | Nest location should be considered with the other clues |
Winged Ants Require a Different Identification Check
Mature imported fire ant colonies can produce winged reproductive ants, so you may occasionally encounter flying ants rather than workers on the ground. Winged ants can also be confused with termite swarmers, particularly when insects collect near windows or other light sources. Virginia Tech notes that mature fire ant colonies produce winged males and females that leave during mating flights.
If the insects you are seeing have wings, GreenShield’s guide to telling ants and termites apart in Virginia covers the body shape, antennae, and wing differences that help separate the two groups. That distinction matters because a termite problem calls for a very different inspection and treatment process than an ant colony.
Where Are Fire Ants Found in Virginia?
Imported fire ants have been reported in Virginia since 1989, and their range has expanded over time. The Virginia Department of Agriculture and Consumer Services imported fire ant program states that Virginia first established its quarantine in 2009 and expanded it in 2019, 2022, and most recently in 2025. As of August 2026, the current VDACS page says the quarantine covers 18 counties and 15 independent cities.
The May 27, 2025 expansion added Chesterfield, Lee, Nottoway, Pittsylvania, Prince George, and Surry counties, along with Colonial Heights, Danville, Hopewell, and Petersburg. That makes imported fire ants especially relevant for homeowners in Chesterfield County, including Midlothian-area properties located within the county.
What the Quarantine Means for Homeowners
Being inside the quarantine does not mean every yard contains fire ants. The regulation is intended to slow their spread by restricting the movement of materials that can carry imported fire ants from regulated areas into areas where they are not established. VDACS lists soil, grass sod, plants with soil attached, and certain equipment and materials among the regulated articles.
The current quarantine map does not list the City of Richmond, Henrico County, or Hanover County. VDACS asks people who suspect imported fire ants outside the quarantine to report the sighting through its Invasive Species Reporting Tool. Within the quarantine, the agency directs residents to use caution and contact their local Virginia Cooperative Extension office for treatment recommendations.
Why Fire Ants Can Become a Problem Around Your Yard
A few workers on the surface can be misleading because most of a fire ant colony is below ground. Virginia Tech reports that mature imported fire ant colonies can contain hundreds of thousands of ants, including workers caring for the queen and developing young. Colonies can also contain more than one queen, depending on their social form.
That colony structure helps explain why simply killing visible ants does not confirm that the nest has been controlled. An effective treatment has to account for the colony below the surface, not just foraging workers. It also helps explain why repeated mounds or continued activity after an incomplete treatment deserve a closer inspection.
Fire Ant Stings Deserve Attention
Imported fire ants bite to hold onto the skin and can sting multiple times. The CDC and NIOSH guidance on fire ant stings says their venom can cause a burning sensation, followed by red bumps that may develop into white, fluid-filled pustules within a day or two. Severe allergic reactions can occur in some people.
The CDC advises immediate medical attention for severe symptoms such as difficulty breathing or serious swelling. Around the home, the practical concern is location: a confirmed mound beside a walkway, patio, play area, garden, or another frequently used part of the yard creates more opportunity for accidental contact.
What Should You Do if You Find Red Ants on Your Property?
When you find red ants in Virginia, start by observing rather than treating immediately. Note whether the ants are coming from a soil mound, whether workers appear to vary in size, and where the activity is concentrated. Photos taken from a reasonable distance may also help with identification without requiring you to disturb the colony.
Next, consider whether your property lies inside the current imported fire ant quarantine. If it is outside the regulated area and you suspect imported fire ants, VDACS asks residents to report the finding. That reporting matters because the agency focuses its suppression efforts on new imported fire ant occurrences outside the established quarantine.
Skip Unproven Fire Ant Remedies
Virginia Tech advises against several widely shared home remedies. Boiling water may not reach the queen and brood located underground, grits do not kill fire ants, club soda does not suffocate a colony, and cinnamon and essential oils are not effective fire ant treatments. Some attempts can also disturb a colony without eliminating it.
A better approach starts with confirming the species and locating the colony. Treatment can then be selected based on where the ants are nesting and the conditions around the property. That prevents a quick application to visible workers from taking the place of an inspection that identifies what is actually driving the activity.
Look Beyond the First Mound
Finding one suspicious mound does not tell you whether other colonies are present elsewhere on the property. A thorough inspection should include nearby lawn areas, landscape beds, edges of pavement, the foundation, and other places where activity is showing up.
This is also where species identification changes the plan. Ants found around a structure may be nesting for very different reasons than imported fire ants in open soil. Finding the cause first makes it possible to apply products and materials where they are actually needed instead of treating every ant problem the same way.
