Three of the Most Common Types of Ants Found in Colorado

While there are several types of ants in Colorado, all species are very social. In fact, they live and work together in very large colonies that use a caste system. Each colony contains workers, soldiers, and reproductives. Of the ants found in Colorado, below is an overview of the three most common types.

Pavement Ants

At approximately 1/8 of an inch in length, pavement ants are quite small. They are dark brown to black in color. 

True to their name, these ants can be found nesting between the  spaces in pavement and sidewalks as well as in the gaps between landscape pavers and bricks. 

Pavement ants will infest homes in search of food.

Carpenter Ants

The largest ants to be found in Colorado, carpenter ants are approximately 1/4 to 5/8 of an inch in length. They are typically black in color but may also be reddish-black in appearance.

Carpenter ants are drawn to wood that is unstained, unpainted, or that has been damaged by water.

Unlike termites, carpenter ants do not eat the wood they infest. Rather they create tunnels to establish nests and hibernation sites.

Sugar Ants

Sugar ants is a term used to describe many species of ants (such as odorous house ants) that have a fondness for sweets but it is also the specific name for the species of ant known as Camponotus consobrinus.

These ants can range in size from 1/16 – 1/2 an inch in length. They have brownish-orange bodies and distinct black heads and hind sections.

While sugar ants do nest outside, they may also establish nests in undisturbed places such as inside walls or in basements.

Colorado Ants FAQs

While some ants in Colorado are merely nuisance pests, not capable of damaging structures or harming people or pets, others may be considered dangerous. For example, carpenter ants can rend extensive damage to homes and businesses. Other ant species are capable of biting or stinging and while the risk is usually minimal, they can cause problems for some individuals.
Ants are found in and around properties nesting and foraging for food and water. If your home is easy to access and if they can find suitable food sources and nesting sites, they will remain a problem.

Great experience with the pest control service. Alexander did a thorough job spraying both the inside and outside of the home and took the time to explain what they were doing. I especially appreciated that he didn’t just treat the home but also pointed out areas around the house that could allow pests to get inside and recommended repairs and preventative measures to help keep them out. The service was professional, thorough, and informative, and I appreciated the attention to detail. I would definitely recommend them to anyone looking for reliable pest control and helpful advice from Alexander on preventing future pest problems.

Our garage had been infested with mice. They left quite a mess. EnviroPest has systematically worked to eradicated the mice, mitigate entry points, and most recently completed a thorough cleanup and sanitation process. Along the way, they have all been professional, friendly, and have gone out of their way to explain their findings and recommendations. I never felt like we were being upsold. Overall very satisfied and would call them again if needed.
