Fire Ants
Solenopsis invicta
Fire ants are small, aggressive red or reddish-brown ants measuring 1/8 to 1/4 inch long. They're known for their painful, burning stings that leave raised, white pustules on the skin. These invasive pests build distinctive dome-shaped mounds in lawns and open areas, with colonies containing up to 250,000 workers.
Habitat & Behavior
Fire ants prefer sunny, open areas and build large mounds in lawns, gardens, playgrounds, and along sidewalks. They're attracted to electrical equipment and can infest air conditioning units, electrical boxes, and utility housings. Colonies may also establish under pavement, in wall voids, or near building foundations when seeking warmth or protection.
Signs of Infestation
- Raised, dome-shaped mounds of loose soil in lawns and landscaping
- Aggressive ants that swarm quickly when disturbed
- Multiple painful stings occurring simultaneously when you encounter a colony
- Dead grass or vegetation around mound areas
- Small ants trailing along sidewalks, driveways, or building foundations
Health & Property Risks
Fire ant stings are painful and can cause allergic reactions ranging from localized swelling to life-threatening anaphylaxis in sensitive individuals. Their venom creates characteristic pustules that can become infected if scratched. Fire ants pose particular dangers to children, pets, and elderly individuals who may be unable to escape quickly. They also damage lawns, gardens, and electrical equipment.
Prevention Tips
- Maintain a clean yard free of food debris and standing water
- Keep grass cut short to make your lawn less attractive to fire ants
- Remove potential nesting sites like lumber, rocks, and debris
- Create a barrier around your home with gravel or landscaping rock
- Inspect your property regularly for new mounds and treat immediately
- Don't attempt to disturb or flood mounds, as this spreads the colony
Professional Treatment Approach
Greenix employs a two-step fire ant control method combining broadcast application of professional bait products with individual mound treatments. Our technicians apply slow-acting baits that worker ants carry back to the colony, eliminating the queen and destroying the entire nest. We follow up with targeted mound drenches for immediate control and establish a protective barrier around your property to prevent reinfestation.

Other common ants you might encounter
Carpenter Ants
Carpenter ants are large, black or dark-colored ants measuring 1/4 to 1/2 inch in length. Unlike termites, they don't eat wood but excavate it to create nesting galleries, leaving behind piles of sawdust-like material called frass. These destructive pests are one of the most common wood-damaging insects in North America.
Sugar Ants (Odorous House Ants)
Sugar ants are small, dark brown to black ants measuring 1/16 to 1/8 inch in length. Often called odorous house ants, they emit a distinctive rotten coconut smell when crushed. These persistent pests are attracted to sweet substances and can quickly establish large colonies with multiple queens inside your home.
Pavement Ants
Pavement ants are small, dark brown to black ants measuring about 1/8 inch in length with distinctive parallel grooves on their heads and thorax. These common household pests get their name from their habit of nesting under pavement, concrete slabs, and along sidewalks. Colonies can contain thousands of workers and multiple queens.
