Roger’s ant is a yellowish-brown to black ant that is usually found in damp places like in leaf litter, soil, under rocks and logs, inside rotting logs, or in potted plants and under slabs inside buildings. It’s less common than other ants but can still become a nuisance, especially in warm and humid environments.
Roger’s ants are small, soil-dwelling ants that can be a concern when they get into buildings or when swarming, stinging females are attracted to lights. These ants are part of a group called ponerines, which are known for being quiet, slow-moving, and hard to notice at first.
Roger’s ants are small ants that blend into their surroundings. Most workers are about 1/16 of an inch long, so they’re easy to miss unless you’re looking closely. They have one large segment at the narrow part of their body, called the pedicel, and the first two parts of their abdomen are slightly pinched, which gives them a distinct shape.
Roger’s ants have a stinger. While they usually keep to themselves, female swarmers are attracted to lights and may sting if disturbed. Their size, shape, and quiet behavior make them different from faster, trail-forming ants you might see in kitchens or around sidewalks.
These ants move slowly and don’t tend to form long trails, making them harder to spot, even when active. Queens are larger and have wings, but you’re unlikely to see them unless the colony is trying to expand. Unlike pavement ants or ghost ants, Roger’s ants are more reserved in their activity.
Roger’s ants follow the typical ant lifecycle. Colonies start when a queen mates and lays her first batch of eggs. These eggs hatch into larvae, which are fed and cared for by workers until they grow into adults. Colonies grow slowly and stay hidden. Because Roger’s ants aren’t as fast-moving or aggressive as other ants, their growth may go unnoticed for some time. However, once they settle into a space, especially a quiet, damp area, they can become tough to remove without help.
Roger’s ants prefer stable temperatures and moisture, which means they’re more active in warm, humid months or indoors in heated buildings during winter. These ants can swarm all year round, and winged adults are often found in insect light traps.
Indoors, they stay active year-round if they have access to warmth and moisture. You might spot them in expansion joints, near boiler rooms, basements, or behind appliances that give off heat. They often go unnoticed because they don’t need daylight and tend to avoid open spaces.
Understanding where Roger’s ants like to live and what they eat can help you avoid infestations or recognize when one has started.
Roger’s ants prefer damp, quiet areas. Outdoors, they nest in soil, leaf litter, or under logs and rocks, and prefer damp residues and debris, crevices around drains, and broken wall tiles. Indoors, they are often brought in via potted plants and tropical plants. They can also thrive in the soil under concrete slabs, greenhouses, and atriums. Since they don’t build large visible nests or long trails, these ants may live undetected until their numbers grow.
Roger’s ants are scavengers and are rarely seen outdoors. Workers forage randomly and lay no trails as live prey are hunted, especially springtails. They also feed on small insects, insect remains, and other protein sources. Indoors, they may be drawn to crumbs, grease, pet food, or other leftover food scraps. However, they don’t have a strong preference for sweet substances like many other ants.
Outdoors, they play a role in breaking down decaying organic matter and help recycle nutrients. Indoors, the female swarmers may sting.
Roger’s ants can be tough to deal with because they move slowly, hide well, and don’t show obvious signs like trails or large nests. That’s why many people don’t realize they have a problem until there are multiple nests or they start appearing more frequently indoors.
While these ants are difficult to remove once they’ve nested indoors, there are ways to make your property less attractive to them. Keep areas clean and dry, especially in kitchens, storage rooms, and basements. Wipe up spills quickly, don’t leave pet food out overnight, and clean under appliances and furniture.
Also, fix leaky pipes and ensure damp areas are well-ventilated. Use caulk to seal cracks in walls, baseboards, and around windows where ants could slip through. Keep leaf litter, mulch, and firewood away from your building’s foundation to reduce outdoor nesting spots near entry points.
It’s a good idea to inspect potted plants as these may be a primary source of introduction. These may be treated and/or disposed of.
Just remember: while these steps may help reduce the chance of an infestation, they aren’t always enough on their own. Once Roger’s ants get inside, professional help is often needed to find and treat the entire colony.
Whether you’re dealing with Roger’s ants or another ant species – like white-footed ants, citronella ants, or ghost ants – Presto-X’s ant control technicians can help. We don’t just treat what’s visible; we inspect for entry points, locate hidden nests, and use targeted baits and pesticidal dust treatment if needed.
Whether you’ve seen Roger’s ants or just want peace of mind, we’re here to help protect your home or business.
The most effective way to get rid of them is by calling a professional who can find and treat the entire colony.
Yes, Roger’s ants can be difficult to control without help. They tend to nest in hidden, hard-to-reach places and may spread quickly, which is why professional pest control is usually needed.
Roger’s ants don’t bite. However, female swarmers are attracted to lights and might sting people in self-defense.
Roger’s ants are named after the scientist who first described them. Their scientific name is Hypoponera punctatissima, but "Roger's ant" is a more common name used in the pest control industry.
They are drawn to dark, damp areas and places where they can find food. This includes decaying wood, mulch, or soil near buildings, as well as crumbs or food waste indoors.
