Seeing large black ants in your home? Carpenter ants can cause serious structural damage by nesting inside wood and expanding their colonies over time.

Carpenter ants are one of the most destructive pests in Calgary. Unlike other ants, they tunnel through wood to build nests, which can lead to serious structural damage over time.
Our treatments are designed to:
Locate hidden nests inside walls and wood structures
Eliminate entire colonies, including the queen
Prevent further damage and reinfestation
We don’t just treat surface activity — we target the source of the infestation.
Early detection is key to preventing costly damage. Common signs include:
Large black ants (6–12 mm) inside your home
Sawdust-like debris (frass) near walls or baseboards
Rustling or faint noises inside walls
Ant activity near windows, doors, or decks
Increased sightings during spring and summer
If you notice any of these signs, it’s important to act quickly.
Carpenter ants prefer damp or damaged wood but can expand into sound wood as colonies grow. Common nesting areas include:
Inside walls and insulation
Wooden beams and framing
Window and door frames
Decks, fences, and exterior structures
Areas with moisture damage
Because nests are often hidden, professional inspection is critical.
We use a proven, step-by-step approach to eliminate carpenter ants completely:
We locate nesting areas, entry points, and signs of structural activity.
We apply professional-grade products directly into nesting zones and high-risk areas.
We focus on eliminating the entire colony, including the queen.
We identify moisture issues and structural vulnerabilities to prevent future infestations.
Store-bought sprays may kill visible ants, but they don’t eliminate the nest inside your structure.
DIY treatments often fail because:
Nests are hidden deep inside walls or wood
Colonies continue growing behind surfaces
Sprays don’t reach the queen
Professional treatment is the only reliable way to stop the infestation and protect your home.
