Ant Prevention & Guide
Ants are one of the most common pest issues for Calgary homes and businesses—some are just a nuisance, while others can cause serious property damage. Understanding the types of ants you're dealing with is key to preventing infestations and protecting your space. Here's a quick breakdown of the three most common ant species we see in Calgary, what they do, and how to keep them out.
Tips to Prevent Ant Infestations
-
Seal cracks and gaps in your foundation, windows, and walls.
-
Trim back vegetation touching the home.
-
Store firewood and building materials away from your house.
-
Eliminate sources of standing water and reduce excess moisture.
-
Clean up food crumbs and keep food in sealed containers.
Carpenter Ants

Colour - Red to black
Size - Up to 5/8"
Wings - Yes
Habitat - Moist, decaying wood such as porch pillars, rooflines, window sills, dead trees, stumps, and any wood in contact with soil.
Summary
Carpenter ants don’t eat wood, but they do chew through it to build their nests. Over time, this can compromise the structure of your home. They leave behind piles of fine sawdust near entry points and can move from rotting wood into solid framing if left untreated.
Odorous House Ants

Colour - Brown to black
Size - 1/16" to 1/8'
Wings - Yes
Habitat - Wall voids, under floors, and exposed soil near homes.
Summary
These small ants give off a strong, rotten coconut-like smell when crushed. They’re attracted to moisture and sweet foods and often invade kitchens. While they don’t pose health risks, they can contaminate food and are difficult to get rid of without proper treatment.
Pavement Ants

Colour - Brown to black
Size - Up to 1/8"
Wings - Yes
Habitat - Under sidewalks, driveways, concrete slabs, and building foundations.
Summary
Pavement ants often nest under concrete and can enter buildings through small cracks. They’re known to forage for a wide variety of food, including sweets and grease. Though not structurally harmful, they can quickly become a persistent nuisance indoors.
