If you live in Ohio, you may have noticed the occasional ant creeping around your house or garden.

But did you know there are actually several different types of ants living in Ohio? Each type of ant has its own unique characteristics, habits, and behaviors.

In this blog post, we’ll take a look at some of the most common types of ants in Ohio, so you can become more knowledgeable about the species living near you.

Types of Ants in Ohio

1. Common Ants

Ohio is home to various ant species, but the most commonly encountered ant is the common garden ant.

These types of ants in Ohio are small (usually about 1/4-inch long) and reddish-brown or black in color.

They are found in large colonies near pavement, sidewalks, or buildings and prefer to nest outdoors in soil or sand. 

These ants feed on various foods, including sweets, proteins, and greasy foods. They are also known to feed on dead insects and other organic material.

Common garden ants are often considered to be nuisance pests, as they can contaminate food sources and even cause damage to structures by burrowing and tunneling beneath them.

While these ants are not typically dangerous to humans, their presence is still undesirable. 

When dealing with an infestation of common garden ants, it’s important to contact a pest control professional to identify and remove the colony.

2. Funnel Ants

These ants enter homes through cracks in foundations, around window frames, or through vents.

It’s important to note that funnel ants do not sting but can bite if provoked. If you find an infestation of funnel ants, it’s best to call a professional exterminator. 

Since these types of ants in Ohio tend to build nests close to buildings and other structures, over-the-counter pest control methods won’t usually eliminate them.

The good news is that funnel ants are relatively easy to spot due to their reddish-brown color and their tendency to build conical “funnels” near entry points into buildings.

3. Tennessee Thread-Waisted Ant

The Tennessee Thread-Waisted Ant is a species of ant found throughout the United States and is especially common in the state of Ohio.

This species of ant is characterized by its small size, ranging from 3 to 5 millimeters in length, and its distinctive yellow-brown color.

Its name derives from the thin thread-like waist that separates its abdomen from its thorax.

These ants are most commonly found in wooded areas, as they feed on dead wood, as well as seeds, honeydew, and nectar.

They create nests within cavities or cracks in dead trees, logs, stumps, and other sources of dead wood.

The Tennessee Thread-Waisted Ant typically lives alone but occasionally can be found in large colonies with up to 500 individuals. 

These types of ants in Ohio can benefit ecosystems, as they help break down dead wood, aiding in the decomposition process and enriching the soil with vital nutrients. They also help to limit the presence of plant-damaging insects. 

Overall, the Tennessee Thread-Waisted Ant is an important part of Ohio’s ecosystem and plays an important role in maintaining the health of our forests and woodlands.

4. Hairless Rover Ants

The Hairless Rover Ant (Brachymyrmex patagonicus) is an ant species native to the United States.

These ants are easy to spot because they have no hairs on their bodies because of their bright yellow-orange color.

The Hairless Rover Ant is a small ant that measures between 1/16 to 1/8 of an inch in length. Their antennae are longer than their body, and their thorax has distinct bumps on it.

As with all ants, the Hairless Rover Ant lives in colonies, with a single queen laying eggs and multiple workers caring for her young.

Due to their small size, Hairless Rover Ants can get into homes quite easily. They will typically not cause any damage but may become a nuisance if there is a large infestation.

To prevent an infestation, it is important to keep your home and yard free of clutter and debris, seal up any cracks or crevices in your home, and use ant bait to eliminate any existing populations.

Also called the yellow hill ant, it is a species of ant found in North Africa, Asia, and Europe, where it is one of the most prevalent ants.

North American populations are currently regarded as belonging to a distinct but similar species called Lasius brevicornis. Males are 3-4 mm long, the queen is 7-9 mm, and workers are 2-4 mm.

They range in color between yellow and brown, with queens and males having significantly darker hues. The species primarily inhabits the ground in lawns and meadows.

Despite the fact that the nests are frequently fully covered by grass, their presence is frequently revealed by little mounds of loose subsoil in the spaces seen between grass stalks.

They may also build their nests beneath concrete slabs or big rocks. Nesting on the lawn

The yellow meadow ant feeds on the root aphid honeydew it produces in its nests for breeding. The aphids themselves may occasionally be consumed in the winter.

The species rarely go hunting outside the nest due to their feeding habits. Their lack of coloration and smaller eyes compared to similar species like the black yard ant are indications that they reside underground.

Being a cautious species, they frequently only seal their tunnels to ward off intruders.

18. Turfgrass Ants

The turfgrass ant, also known as the sidewalk ant, can be commonly found in well-drained soils of sunny turf surfaces in yards, parks, and golf courses.

19. Little Black Ants

An ant species that are native to North America is called the little black ant (Monomorium minimum).

The workers are 1 to 2 mm long, and the queens are 4 to 5 mm long. It is a lustrous black color.

A nest may contain more than one queen because it is a polygyne species with just one worker caste. A colony typically has a few thousand workers and is of moderate size. 

Types of ants in Ohio, known as Monomorium minimum, will eat anything, including dead insects and bird droppings. They consume fall webworm larvae as well as codling moth larvae.

Although they nest on earth mounds, workers may browse in homes. They gather aphid honeydew from species like the soybean aphid (Aphis glycines).

The queens’ mid-summer courtship. The males undertake the nuptial fly, mating in midair, and the queens engage in midsummer wooing.

The guys pass away soon after. Each queen builds a fresh nest, removes her wings, and lays eggs. It takes around a month for an egg to mature into an adult.

20. Little Crazy Ants

The Formicinae subfamily contains a sizable genus of ants called Nylanderia. The genus has a practically global range, with species living in a variety of environments over almost the whole globe.
