Ants are a family of eusocial insects that, like wasps and bees, belong to the order of hymenoptera, ants can form their nest in very different places: on the ground, under stones, in the roots of plants, in the interior of wood or cork of living or dead trees, hollow stems, acorns, leaf-shaped habitats, in human constructions, Despite this, a few species affect the human being in various ways, by contaminating food or surgical instruments in hospitals, nest on grass or other structures such as flowerbeds, plant roots, trunks of ornamental trees or pavement, feeding on sprouts, defoliating or biting fruits of plants, protecting plague insects such as aphids, mealybugs or whiteflies, entering to steal food in houses or nesting in wooden structures or electrical installations, and therefore, causing serious damage that often results in large economic losses

What is an Acrobat Ant?
Acrobat ants get their common name from their ability to acrobatically raise their abdomen over their thorax and head, especially when disturbed. In comparison to other ant species, acrobat ants are nothing more than a slight nuisance. However, if their colony is disturbed, acrobat ants may sometimes bite. There are various species of this light brown to black ant found throughout the United States, even at altitudes of up to 8,000 feet.

What Do Acrobat Ants Look Like?
Acrobat ants are light brown to black in color. They are relatively small, usually measuring about 1/8” (3.2 mm) in length. Queens, however, are generally larger but can range in size up to 3/8” (10 mm) long. Acrobat ants have a segmented body and when looked down upon, the shape of their abdomen resembles a heart. These ants possess a stinger, and their antennae are 11-segment with a 3-segmented club.

Signs of an Infestation
The most obvious sign of an acrobat ant infestation is the presence of actual ant trails on wires, utility lines and pipes coming into walls. Acrobat ants will occasionally forage up to 100 feet away from their nest for resources, so you might spot them trailing along the foundation in search of food. Additionally, debris such as dirt and wood scraps that acrobat ants deposit as they excavate their nests can serve as another telltale sign of an infestation. If the home has siding, look for pieces of foam insulation, which could indicate an acrobat ant nest behind the siding.

Homeowners should also check for moisture damage around the structure of the home, which could attract acrobat ants, carpenter ants and other wood-nesting pests like termites. Keep an eye out for peeling paint, mold or fungal growth, or deteriorating wood along soffits and around window frames.


The term “sugar ants” encompasses several types of ants, including some that nest outdoors and only come inside to feed on sweets, as well as others that prefer to nest and feed inside a home—possibly your home. Outdoor “sugar ants” include: Acrobat antsCornfield ants.


What are yellow crazy ants?
The yellow crazy ant is listed as one of the top 100 worst invasive species by the IUCN and the Global Invasive Species Database. They are a category three restricted pest under the Biosecurity Act 2014. As such, all citizens have a general biosecurity obligation to minimise the risk of further infestation.

Why Are Crazy Ants Such A Problem?
All ant species can contaminate food sources, but most aren’t dangerous to people and don’t cause property damage. The crazy ant, however, can cause both property damage and pose health risks.

First of all, they are known to get into electrical equipment, creating shorts and other dangerous and expensive damage. They have large colonies and can invade this equipment in overwhelming numbers.

Secondly, crazy ants can spread the bacteria and pathogens from their body and legs to food and any surfaces they come in contact with. Animals are also at risk as crazy ants are known for crawling into and around the eyes and ears of livestock and small animals.

How Can You Prevent Crazy Ants?
Since crazy ants can damage property and are unsafe to have around for health reasons, knowing how to prevent them is key, especially important because crazy ants are difficult to remove once an infestation begins. They are an invasive species that can reproduce quickly and grow into large colonies, often referred to as super colonies, and can quickly overwhelm a property.

To reduce the risk of an infestation, follow these five steps:

Seal any areas where ants can get inside with caulk to fill up cracks and crevices in the home’s walls and foundation.
Install door sweeps and weatherstripping.
Since crazy ants are attracted to food, place lids on outdoor trash cans to keep them from foraging.
Trim shrubs, trees, and bushes away from the outside of the building.
Patch up weak areas around where wires and pipes enter your home or business.


Carpenter ants are among the largest ants that people encounter around their homes. Workers measure up to a 1/2 inch. The queen is slightly larger. In a single colony, you may find ants of varying sizes, however, as there are also smaller workers that reach just 1/4 inch in length.

Color varies from species to species. The common black carpenter ant is, predictably, dark in color, while other types may be yellow or red. Carpenter ants have a single node between the thorax and abdomen. The top of the thorax appears arched when viewed from the side. A ring of hair encircles the tip of the abdomen.

In established colonies, two castes of sterile female workers develop – major and minor workers. The major workers, which are larger, defend the nest and forage for food. Minor workers tend to the young and maintain the nest.

Most carpenter ants build their nests in dead or decaying trees or logs, though they do also inhabit landscape timbers and wooden structures, including people’s homes. They prefer moist or partially decayed wood, so carpenter ants in the home may suggest a water leak has occurred.

Carpenter ants do not eat wood. They are true omnivores and not all that picky about what they will consume. Carpenter ants will forage for honeydew, the sweet, sticky excrement left behind by aphids. They’ll also eat fruits, plant juices, other small insects and invertebrates, grease or fat, and anything sweet, like jelly or syrup.

Life Cycle
Carpenter ants undergo complete metamorphosis, in four stages from egg to adult. Winged males and females emerge from the nest to mate beginning in the spring. These reproductives, or swarmers, do not return to the nest after mating. Males die, and females establish a new colony.

The mated female lays her fertilized eggs in a small wood cavity or in another protected location. Each female lays about 20 eggs, which take 3 to 4 weeks to hatch. The first larval brood is fed by the queen. She secretes fluid from her mouth to nourish her young. Carpenter ant larvae look like white grubs and lack legs.

In three weeks, the larvae pupate. It takes an additional three weeks for the adults to emerge from their silken cocoons. This first generation of workers forages for food, excavates and enlarges the nest, and tends to the young. The new colony will not produce swarmers for several years.

Special Adaptations and Defenses
Carpenter ants are largely nocturnal, with workers leaving the nest at night to forage for food. The workers use several cues to guide them to and from the nest. Hydrocarbons from the ants’ abdomens mark their travels with a scent to assist them in returning to the nest. Over time, these pheromone trails become major transportation pathways for the colony, and hundreds of ants will follow the same path to a food resource.

Camponotus ants also use tactile trails to find their way back and forth. Ants feel and remember the distinct edges, grooves, and ridges in tree trunks or sidewalks as they move through their environment. They also employ visual cues along the way. At night, carpenter ants use moonlight to orient themselves.

To appease their appetites for sweets, carpenter ants will herd aphids. Aphids feed on plant juices, then excrete a sugary solution called honeydew. Ants feed on energy-rich honeydew, and will sometimes carry aphids to new plants and “milk” them to get the sweet excretion.

Range and Distribution
Camponotus species number about 1,000 worldwide. In the U.S., there are approximately 25 species of carpenter ants. Most carpenter ants live in forest ecosystems.
