26 Different Types of Ants in New York

New York is home to a wide variety of ant species, each with unique characteristics and behaviors.

Whether you’re an avid entomologist or just curious about the kinds of ants that make their homes in the Big Apple. 

This blog post will explore the various types of ants in New York.

From pavement ants to acrobat ants, learn more about the different species of ants living in the city and why it’s important to be aware of their presence.

1. Argentine Ant

Argentine Ants are the first on the list of types of ants in New York. If you’re living in New York, you might want to watch for Argentine ants. These small, dark-colored ants are one of the most common types of ants in New York, and they can quickly become a nuisance.

Argentine ants often form large colonies and can be seen traveling long lines looking for food. They are small, measuring only about 1/8th of an inch in length, and have light brown coloration. They have six legs, two antennae, and no wings. They love sweet foods like honeydew and nectar but will also feed on insects, plant matter, and other items in and around your home.

One of the biggest problems with Argentine ants is that they can easily enter homes or businesses through small openings. This means that if you have any cracks in your foundation, walls, or windows, these ants may be able to find their way inside. Once inside, they will quickly start building nests and foraging for food.

The best way to prevent Argentine ants from entering your home is to ensure that all potential entry points are sealed and properly maintained. Additionally, keeping areas around your home free of debris and clutter can help reduce their food sources and make it more difficult for them to nest. If you are dealing with a large infestation, it’s best to contact a pest control professional as soon as possible.

As with other ant species, the Little Crazy Ants can become pests when they start building large colonies in and around buildings. 

Because of their tiny size and quick movements, it can be difficult to locate and remove these ants from your home or business. If you think you may have an infestation, it is important to contact a professional exterminator as soon as possible. Prompt action can help prevent any potential damage or health risks associated with an uncontrolled infestation.

24. Hairy Big-headed Ant

Pheidole pilifera, the hairy, big-headed ant, is commonly found in New York. The ants are characterized by their small size, black color, and, most notably, their hairy bodies. They are one of the most common types of ants found in New York City and can often be seen scurrying around yards and sidewalks.

These ants prefer to nest in dry soil or mulch but can also be found in rotting logs, under stones, and tree bark. While they are not considered a nuisance pest, they can damage flowers and other vegetation when they feed on plant sap. 

Pheidole pilifera are omnivorous and will eat both plant and animal material. They feed on other insects, sugary foods, oils, and decaying organic matter. They are also scavengers, meaning they will feed on whatever food sources they can find.

These ants in New York generally live in small colonies of up to 200 individuals, but larger colonies have been observed. They are active year-round and tend to be most active during the year’s warmer months. If you spot these little critters around your home or yard, don’t worry! They are usually harmless and can help reduce the number of other unwanted pests.

25. Slave-raiding Ant

The Polyergus sanwaldi ant, otherwise known as the slave-raiding ant, is native to the New York City area. Due to its unusual behavior, this ant is one of the most fascinating types in New York. 

Unlike other types of ants in New York that scavenge for food or build nests, the Polyergus sanwaldi ants raid the colonies of other ant species and steal their larvae. The larvae are then brought back to the Polyergus sanwaldi colony and forced into slavery, where they take care of the queen and do all the hard labor.

This unique behavior has made them a highly sought-after species among entomologists who study social behavior in insects. Despite their impressive reputation, these ants are relatively small and can easily be missed when out exploring nature in NYC

26. Dieck’s Slender Ant

Last on our list, Dieck’s slender ant, or Stenamma diecki, is one of the most common types of ants in New York. This ant can be identified by its narrow, cylindrical body and light yellow coloring. It is often found under logs and rocks, in leaf litter, rotting wood, and soil.

Dieck’s Slender Ants’ diet typically consists of small insects, nectar, and honeydew from aphids and scale insects. While they are not necessarily pests, they can become a nuisance when large colonies start forming in homes and businesses.

If you have Dieck’s slender ant infestations, the best way to get rid of them is to combine baiting and physical removal. Baiting involves liquid or granular insecticides that attract the ants to feed on it. These insecticides contain either a slow-acting poison or an insect growth regulator that helps to prevent the colony from growing further.

Physical removal methods involve removing the ants’ nesting sites by sweeping up any piles of wood chips or leaves where the ants might be living. You can also use a vacuum to suck up the ants, making sure to dispose of the bag afterward.

Overall, Dieck’s slender ant is just one of the many types of Ants in New York. To ensure they don’t become an issue, take proper preventative measures and remove any nesting sites you find around your home.
