Which Ants Call Florida Home?


The Sunshine State is host to several ant species, each with its own distinct traits and behaviors. Here are the most common.


Acrobat ants (Crematogaster)

Acrobat ants are named for their unique ability to acrobatically raise their abdomen over their thorax and head, especially when disturbed. They are small, typically measuring about 1/8 inch in length, and their color ranges from light brown to black.


One of the distinctive features of the acrobat ant species is their heart-shaped abdomen, which is not only a key identifying characteristic but also plays a role in their acrobatic displays.


These ants' diet primarily consists of honeydew, a sweet substance produced by aphids and other sap-feeding insects. This preference often leads them to form symbiotic relationships with these insects, protecting them from predators in exchange for their sugary secretions.


In urban settings, acrobat ants can become a nuisance, especially when they infest homes. They are particularly attracted to wood damaged by water or termites, which they can further excavate to create their nests. While they don't pose a significant health threat, their presence can be a sign of underlying moisture issues in a building.


Argentine ants (Linepithema humile)

Argentine ants are a particularly prevalent species in Florida. Often mistaken for sugar ants due to their similar size and shared fondness for sweets, Argentine ants are small, measuring about 1/8 inch in length, and are usually brownish in color.


These ants are not native to the United States. They originated in South America and have since become one of the most invasive ant species worldwide.


One of the most notable characteristics of Argentine ants is their aggressive behavior, especially towards other ant species. They are known for displacing native ant populations and forming enormous super-colonies that can extend across large areas. This competitive nature allows them to dominate food sources and habitats.


In residential areas, Argentine ants are often found trailing along kitchen counters, pantries, and dining areas in search of crumbs, sugary spills, and other food residues. Their preference for moist environments often leads them to nest in damp areas both inside and outside homes, such as under potted plants or within wall voids.


Despite their small size, their ability to rapidly breed and form large colonies makes them a persistent nuisance in homes.


Bigheaded ants (Pheidole megacephala)

Big-headed ants are easily identifiable by their large heads, particularly the soldier class within the species. These ants display a clear division of labor, with the larger-headed soldiers responsible for defense and the smaller workers taking care of foraging and nest maintenance. They vary in color but are generally light to dark brown.


An interesting aspect of big-headed ants is their dietary flexibility. They feed on a wide range of foods, including other insects, seeds, and honeydew. However, they are particularly drawn to greasy and protein-rich foods, which often leads them into homes.

While they don't typically cause structural damage like carpenter ants, their nesting behavior can be problematic. They prefer to nest in soil but can also establish colonies in wall voids, under potted plants, and in other hidden areas within a home.


When nesting inside, they can excavate enough soil to cause visible piles, which is often mistaken for termite activity.


Carpenter ants (Camponotus spp)

Florida carpenter ants are known for their large size and formidable presence. These ants, predominantly black or dark brown, are easily distinguishable by their relatively large bodies, which can range up to half an inch in length.


Unlike termites, carpenter ants do not consume wood, but they are renowned for their ability to excavate wood to create intricate nesting galleries, which can lead to significant structural damage over time.


Carpenter ants have a preference for moist, decaying wood, which is why they love homes with leaks or damp areas. They often enter buildings through cracks around doors, windows, or through holes for wires and pipes, particularly where wood is damp.

Carpenter ants are primarily nocturnal, venturing out at night to feed on various substances, such as living and dead insects, meats, fats, and sugary foods, including honeydew produced by aphids.


Their nesting habits can be quite destructive. Inside homes, they may establish nests in various locations, often in moist areas like around sinks, bathtubs, poorly sealed windows/door frames, roof leaks, and poorly flashed chimneys. Outside, they are commonly found in rotting fence posts, stumps, and dead portions of standing trees.


Fire ants (Solenopsis invicta)

Fire ants stand out for their notorious behavior. These small ants, with a reddish-brown to black coloration, are infamous for their aggressive nature and the painful stings they deliver.

Typically, fire ants build large, visible mounds in open areas, and these mounds can be surprisingly extensive underground. Disturbing these mounds often triggers a swift and fierce response, with ants swarming out to attack perceived threats.


Their stings are not only painful but can also pose significant health risks, particularly to individuals with allergies to their venom. Even for those without allergies, the stings can lead to discomfort and secondary infections if not properly cared for.


Beyond the individual health risks, fire ants also impact the environment and local ecosystems. They prey on ground-nesting wildlife, small mammals, and birds, and can disrupt agricultural activities. Controlling fire ant populations is challenging due to their aggressive nature and rapid breeding.


Ghost ants (Tapinoma melanocephalum)

Ghost ants are tiny and pale with an almost translucent appearance that renders them nearly invisible. They are particularly common in kitchens and bathrooms, where their attraction to moisture and sugary substances often leads them. This preference for sweet foods has also earned them the nickname 'sugar ants,' although this term is often used to describe various ant species with similar diets.


One of the most distinctive aspects of ghost ants is their ability to seemingly appear and disappear in homes, earning them their ghostly moniker. This is due to their small size and pale color, which allow them to blend in easily with their surroundings. They can often be found trailing along countertops, inside cabinets, and around sinks, always in search of food or water.


Despite their tiny size, ghost ants can be a significant nuisance in homes. They are known for their ability to establish multiple nesting sites, both indoors and outdoors. Their nests are usually well-hidden, and they are also capable of rapid population growth, with colonies containing multiple queens that can split off to form new colonies if threatened.

In addition to being a household pest, ghost ants can also be problematic due to their attraction to electrical equipment. They have been known to infest electrical outlets and appliances, potentially causing short circuits or other damages.


Little black ants (Monomorium minimum)

Little black ants, while small and less conspicuous compared to other species, can be just as much of a nuisance in Florida homes. Their preference for sweet substances often leads them to invade kitchens, where they are drawn to sugary spills, crumbs, and unsealed food items. In their quest for food, little black ants form distinct trails, which can be a telltale sign of their presence in a home.


These ants typically establish their primary nests outdoors, often in decaying wood or under rocks, but they don't hesitate to venture indoors. Their small size enables them to enter homes through tiny cracks and crevices, making them a frequent indoor pest. Once inside, they can be challenging to control due to their tendency to form satellite colonies in various locations.


The presence of little black ants in homes can indicate other underlying issues, such as moisture problems or decaying wood, which are attractive nesting sites for these ants. Their ability to exploit small spaces and their rapid breeding cycle can make them a persistent issue once they establish themselves.


Odorous house ants (Tapinoma sessile)

Odorous house ants are infamous for the distinctive, rotten-coconut-like smell they release when crushed. These small, dark brown to black ants are incredibly adaptable and can thrive in a variety of environments, but they have a particular fondness for inhabiting human dwellings. Drawn to sweet foods, they can become persistent pests in kitchens, raiding sugary spills, and unsealed food containers.


Their ability to nest indoors makes them a significant concern for homeowners. Odorous house ants often establish colonies within the structures of homes, favoring secluded and moist spaces. These colonies can grow large, with multiple queens and numerous workers, making them a challenging pest to manage.


The odorous house ant's diet isn't limited to sweet. They also feed on dead insects and other protein sources, showing their opportunistic feeding habits. This adaptability, combined with their preference for indoor nesting, means that these ants can be present year-round, becoming a constant source of annoyance.


Pharaoh ants (Monomorium pharaonis)

Pharaoh ants, with their light yellow to red bodies and darker abdomens, are one of the smallest ant species encountered in Florida homes. Despite their tiny size, they pose significant challenges due to their highly adaptable and resilient nature. These ants are notorious for creating large colonies with multiple nests, making them particularly difficult to eradicate once they infest an area.


What sets Pharaoh ants apart is their preference for indoor environments, often making their way into homes, hospitals, and other buildings in search of food and shelter. They are attracted to a variety of food sources but show a particular preference for greasy foods, sweets, and proteins. This diet makes kitchens and food storage areas prime targets for Pharaoh ant infestations.


The real concern with Pharaoh ants lies in their potential to spread diseases and bacteria, especially in healthcare settings. They can contaminate sterile areas and equipment, posing a risk to patients. Their small size allows them to access almost any space, making them incredibly invasive.


In homes, they often nest in hard-to-reach places like wall voids, under appliances, or inside insulation, further complicating control efforts.


Pavement ants (Tetramorium spp)

Pavement ants, a common sight on the sidewalks and driveways of Florida, are small, usually dark brown to black in color. They earned their name from their preference for nesting in or under cracks in the pavement. You can often spot these ants marching in a line, foraging for food, and carrying tiny particles back to their nests.


These ants measure about 1/8th of an inch and are recognizable by their parallel lines on the head and thorax. While they are not aggressive towards humans, pavement ants can become a nuisance when they enter homes in search of food.


They are omnivorous, feasting on a variety of foods, including insects, grease, seeds, and sweets. This diverse diet means they can easily adapt to different environments, making them a persistent pest in urban and suburban areas.


Pavement ants typically nest outdoors under stones, along curbs, or in cracks of pavement, but they can also find their way indoors through tiny openings in search of food and warmth. Inside, they may nest in walls, insulation, or under floors. While they don't cause structural damage like carpenter ants, their presence can be bothersome.
