In this blog post, we’ll be taking a deep dive into all of the most common types of ants in Utah State. 

We’ll discuss their habits, habitats, and other important information you need to know about these fascinating creatures.

So, let’s get started!

1. Boulder Collared Ant

The Boulder Collared Ant, Aphaenogaster boulderensis, is the first on the list of types of ant in Utah.

These small ants range from 1/8th to 1/4th of an inch long and are typically brown or black. They are a native species often seen foraging around the landscape and in gardens.

Boulder Collared Ants prefer dry areas with sparse vegetation, such as open grassy fields and meadows.

They are most active during the summer months and can often be seen traveling in long trails that they use to follow food sources.

They have been known to feed on honeydew, seeds, insects, and even bird droppings. These types of ants in Utah form large colonies, typically nesting in soil or under rocks and logs.

The queens will often produce up to 8 egg-laying chambers and can produce hundreds of workers throughout their lifetime. 

The Boulder Collared Ant is also known to be a good pest controller, feeding on other insects that may harm your garden.

If you live in Utah and think you may have a Boulder Collared Ant infestation, it is best to call a professional pest control company to take care of the problem.

While this ant is not generally considered a nuisance pest, it can become a problem if its numbers get out of control.

However, with proper management and treatment, these types of ants in Pennsylvania can be easily managed and kept in check.

2. Dark Rover Ant

The dark rover ant (Brachymyrmex patagonicus) is one of the types of ants in Utah. These ants are typically dark-brown to black, with pale yellow legs and antennae. They have a unique, flat-bodied shape and a two-segmented petiole.

Dark rover ants are active foragers who feed on various food sources, including sweet liquids, proteins, and other insects.

They can also be found nesting in soil, under logs and stones, or in the cracks of buildings and sidewalks.

In terms of behavior, the types of ants in Utah are typically quite active during the day and can often be seen running around searching for food.

They are also known to attack larger animals aggressively and have been known to sting humans when provoked.

Due to their hardiness and scavenging habits, dark rover ants are considered beneficial to gardens and farms as they can help control other insect pests.

However, they can also become nuisance pests if their populations become too large. In such cases, it is best to call an exterminator to address the problem.

3. Essig’s Carpenter Ant

One of Utah’s most commonly found types of ants is Essig’s carpenter ant, also known as Camponotus essigi. This ant is a small black species and is usually about 8-10mm long.

The Essig’s carpenter ant is found throughout Utah but is more common in higher elevations.

It prefers to live in moist and shady areas, such as rotting logs and stumps, leaf litter, and around wood piles. It will also set up nests in wood structures like houses and other buildings.

The Essig’s carpenter ant is social, living in large colonies of up to several thousand individuals. They feed on various items, including honeydew from aphids, insects, and nectar. The colony will send workers to collect food and return it to the nest.

Essig’s carpenter ants can be a nuisance if they enter homes and buildings and start nesting. It is important to find their nest and remove or eliminate access to food sources to get rid of them.

Additionally, controlling moisture levels around the home can help deter them from entering.

4. Hyatt’s Carpenter Ant

The Hyatt’s Carpenter Ant (Camponotus hyatti) is also one of the types of ants in Utah. It is one of the most common ant species in the region and is often found in urban areas such as gardens, yards, and parks.

The Hyatt’s Carpenter Ant is a medium-sized ant measuring 5 and 7 mm in length. It is black or dark brown with yellowish or red legs and antennae.

The types of ants in Utah are characterized by their large heads, long abdomens, and wings that are usually half the size of their bodies.

The Hyatt’s Carpenter Ant is a wood-dwelling ant that prefers to nest in moist wood such as logs, stumps, and dead trees.

They are omnivores, meaning they feed on plant material and other small insects. They also scavenge for food, including dead insects and other decaying organic matter.

These types of ants in Utah are beneficial to humans as they help control pests and can be used as natural pest control agents.

They are not considered a nuisance species. However, they can sometimes become a problem when they invade buildings searching for food.

If you come across a colony of Hyatt’s Carpenter Ants in your home or garden, contacting a pest control professional is best to determine the best course of action.

5. Saint Valentine Ant

The Saint Valentine ant, Aphaenogaster cockerelli, is a species of ant found primarily in the western United States, particularly in Utah.

It is an attractive ant, with its black and orange coloration and small size (just under an inch). These types of ants in Utah are highly social and live in large colonies, often with many different queens.

The Saint Valentine ant has a unique behavior that sets it apart from other ants. Instead of foraging for food, these ants spend most of their time gathering resources for their colonies, such as wood chips, stones, and other materials. 

They also have an interesting nesting strategy. They dig shallow burrows in the ground and line them with wood chips and other materials they have gathered. This creates a shelter for their colony, protecting them from the elements and predators.

These types of ants in Utah also have an interesting mating ritual. On the day before Valentine’s Day (February 13th), the workers will participate in a group mating event.

During this time, several males fly around looking for a mate while the female workers wait at the colony entrance.

When a male finds a female he likes, he will present her with food, and then they will mate. This ritual has earned them their name, the Saint Valentine ant.

Saint Valentine is an interesting species of ant and can provide hours of observation and entertainment for those who enjoy watching ants.

They are relatively easy to care for, so if you’re looking for an interesting ant species to observe and learn about, Saint Valentine may be perfect!

6. Bicolored Pyramid Ant

The Bicolored Pyramid Ant, also known as the Dorymyrmex bicolor, is an ant in Utah. This ant species is one of the more common types in the state and is often seen near sidewalks, buildings, and yards.

The Bicolored Pyramid Ant is identified by its yellowish-brown coloration with reddish-brown stripes running along its body.

Its antennae are usually long and slender, and its body is marked with a distinctive pyramid shape. This ant species is generally found in small colonies, ranging from a few dozen to several hundred workers.

The Bicolored Pyramid Ant is known for its aggressive behavior and for foraging widely in search of food.

They have been observed to feed on small insects, honeydew from aphids, and nectar from flowers. They are also known to carry bits of debris, such as sand, pebbles, and pieces of bark, back to their nest.

Though they can sometimes be considered an annoyance, the Bicolored Pyramid Ant plays an important role in the environment.

They help to disperse and spread seeds, as well as help break down decaying plant matter. They can also help to protect plants from other pests, making them an important part of the ecosystem.

7. Pyramid Ant

One of the most common types of ants in Utah is the Dorymyrmex insanus, or pyramid ant. This small ant species lives in colonies of up to 30 individuals and builds pyramid-shaped mounds in the soil.

They are dark brown and measure around 5 millimeters in length. These types of ants in Pennsylvania feed mainly on honeydew from aphids and other small insects.

They also eat plant sap and can even scavenge for dead insects. Pyramid ants have strong mandibles, which help them to break apart food sources that are hard to chew.

Pyramid ants can be found in both urban and rural areas of Utah. They are often seen in gardens and lawns but also in wooded areas.

It is important to note that these ants can cause damage to plants, so it is important to take steps to control their numbers if they become a nuisance.

The nest of the pyramid is quite complex, with multiple chambers connected by underground tunnels. The queen lays her eggs in the center of the nest while workers bring food and remove waste from the nest.

If the nest is disturbed, workers quickly swarm the area and release a pheromone to attract other ants from nearby colonies.

So if you’re out exploring in Utah and surrounded by pyramid-shaped mounds of dirt, chances are you’ve stumbled upon a colony of Dorymyrmex insanus ants.

Be sure to avoid disturbing them and watch out for any potential damage they may cause to plants in the area.

8. Red Wood Ant

These ants are an important part of the ecosystem as they help to control the populations of other insects, including some crop-damaging pests. 

These types of ants in Utah typically nest in dead trees or logs, often near conifers. They also nest under rocks and in gardens. 

They feed primarily on sap, nectar, and small insects. The colonies they form can contain thousands of individuals and communicate by releasing chemical signals called pheromones.

9. Shampoo Ant

Formicoxenus provancheri, also known as the shampoo ant, is next on the list of types of Ants in Utah.

Their reddish-brown color and long legs can identify them. It is found primarily in sandy soils and can often be seen digging and foraging in large groups.

The shampoo is an active forager, often traveling long distances in search of food. They feed primarily on other insects but will also eat fruit and vegetable matter.

Colonies are usually found near water sources or where soil moisture levels are higher. These ants in Pennsylvania live in colonies with up to several hundred individuals.

The colony is organized into different social classes, with the queen at the top and workers below.

The workers care for the nest, while the queen is responsible for laying eggs and producing new colony members. Shampoo ants are beneficial insects since they help control other pest species.

They also provide important ecosystem services such as aerating the soil and decomposing organic matter. 

Despite their benefits, these types of ants in Utah can become a nuisance if they invade homes or yards in large numbers.

Fortunately, shampoo ants can be managed with chemical and non-chemical methods, such as using baits or barriers around the home.

10. The Ponerine Ant

One of the most interesting types of ants in Utah is the ponerine ant, Hypoponera opacior. These types of ants in Pennsylvania are unique in how they live and reproduce and their small size.

Ponerine ants are very small, usually between 0.5-1 millimeter long. They have a reddish-brown coloration with a glossy sheen, giving them their scientific name, opacior, which translates to shiny.

Unlike many other ants, these creatures don’t form colonies; instead, they are solitary and live alone or in small groups.

Ponerine ants have specific habitat requirements; they need moist soil with plenty of organic material to feed on.

This makes them most often found in forested areas, although they can also be seen in urban areas near parks or gardens.

These types of ants in Pennsylvania have an unusual way of reproducing; rather than reproducing through eggs and larvae, they clone themselves by budding off from a single-parent organism.

This process creates two identical clones who can become independent and go off independently. 

Ponerine ants aren’t harmful to humans but can be annoying if they enter homes or gardens. As with any ant species, it’s important to properly identify them and take steps to control their population if necessary.

11. Cornfield Ant

These types of ants in Utah live in colonies and can be found in various habitats in Utah, such as woodlands, fields, and gardens.

They often live near other ant species and tend to cohabitate with other ant types. Mossy-thin ants feed on small insects and aphids and scavenge food. 

They tend to be very active during the warmer months when they are most likely to be seen running around searching for food.

Because of their small size, mossy thin ants don’t pose a threat to humans and animals. They are not known to bite or sting, so there is no need to worry about them around your home or garden.

14. Mourning Tree Ant

The Mourning Tree Ant, also known as Liometopum luctuosum, is an ant species found primarily in the western United States, including Utah.

It is a large, black ant that gets its name from its mourning behavior: when a colony member dies, other ants will gather around it and remain motionless for several hours.

The Mourning Tree ants in Utah are species of Formicinae, a subfamily of ants mostly found in North America and parts of Europe.

They prefer habitats with high moisture levels and vegetation, so you’ll find them in damp woods and grasslands. The Mourning Tree Ant is especially abundant in Utah’s Cedar City region.
