How Many Types of Ants are in Minnesota?

There are over 100 different species of ants in Minnesota, and the last place you would ever want to find them is in your house. Luckily, there are only a few types of ants you can find in or around your home. While finding any type of ant inside your house may be unsettling, identifying the specific type of ant is crucial for effective pest control. Our experts have provided this ant identification guide, with the  four most common ants our pest technicians find in homes across the Minneapolis and St. Paul area.

How do I know what kind of ants are in my house?

The four most common ant pests you could encounter in your home are pavement ants, carpenter ants, field ants, and odorous house ants. Below we have segmented out these four different ants and how to identify them based on size, location, behavior, and other key identifiers.

Pavement Ant Hill between cracks in pavers

  • Small (around 3 mm)

How did ants get in my house?

Now that you have identified the type of ant in your home, you can better address the issue at hand. The ants you see inside your home are most likely workers scouting for food. A good step in preventing ant problems in the first place is by storing all of your food in air-tight containers. Once worker ants find a food source, other ants will follow close behind by using the previous ant’s trail.

The food source they prefer can differ based on the species, colony, and time of year. This is why our technicians use a combination of baits along with a perimeter treatment around the foundation of your house for our ant treatment service. Learn more about our ant control service.
