Common Ant Species in Calgary
Identifying the ant species is critical — each requires a different treatment approach
Camponotus species
Large black ants that damage wood structures by tunneling through them to create nests. The most destructive ant species in Calgary homes.
ID: 6-13mm long, black or dark brown color
Habitat: Wooden structures, tree stumps, firewood
Tetramorium caespitum
Small ants commonly found nesting in cracks of pavement and under stones. Often invade homes in search of food.
ID: 2.5-4mm long, light brown to black color
Habitat: Driveways, sidewalks, building foundations
Monomorium pharaonis
Tiny indoor ants that are extremely difficult to control due to their multiple queen colonies and colony splitting behavior.
ID: 2mm long, pale yellow to reddish color
Habitat: Inside buildings, warm areas near food
Tapinoma sessile
Common household ants that emit a coconut-like smell when crushed. Form large colonies with multiple queens.
ID: 2.5-3mm long, dark brown to black color
Habitat: Indoor areas, particularly kitchens and bathrooms
Our Professional Ant Control Process
Three-step approach that eliminates the entire colony — not just the ants you see
Inspection & Identification
Our licensed technicians locate colonies, identify the ant species, and determine the full extent of the infestation. Different species require different treatment approaches — what works for pavement ants won't work for carpenter ants or pharaoh ants.
Targeted Treatment
We use species-specific baiting systems that target the entire colony including the queen, plus perimeter sprays and dusts for barrier protection. This eliminates the colony at the source rather than just killing foraging workers.
Prevention & Exclusion
We seal entry points, eliminate attractants, and create protective barriers to prevent future infestations. Includes detailed recommendations for long-term ant prevention specific to your property.
Prevention Tips for Homeowners
Seal cracks and crevices around doors, windows, and foundations
Keep kitchen surfaces clean and store food in airtight containers
Fix leaky pipes and eliminate standing water sources
Trim vegetation away from the house exterior
Remove debris, woodpiles, and potential nesting sites
Clean up spills and crumbs immediately
Keep trash cans sealed and away from the house
Repair weatherstripping around doors and windows
Why Professional Ant Control Matters
DIY ant sprays only kill the ants you see — the colony remains intact and keeps producing new workers. Professional ant control targets the colony at its source, including the queen, ensuring complete elimination.
Carpenter ants can cause significant structural damage to your home, tunneling through wooden beams, joists, and framing. Left untreated, carpenter ant damage can be as costly as termite damage.
Pharaoh ants are notoriously difficult to control because spraying causes them to split into multiple colonies, making the infestation worse. Professional baiting is the only effective approach.
Important: Store-bought ant sprays can make some infestations worse by causing colony budding. Professional treatment is the most effective and long-lasting solution.
Ant Control in Calgary — What You Need to Know
Ants are one of the most common household pests in Calgary, particularly during spring and summer when colonies are most active. While ants may seem like a minor nuisance, certain species — especially carpenter ants — can cause significant structural damage to your home. Calgary Pest Guard provides professional ant control services that include species identification, colony elimination, entry point sealing, and long-term prevention strategies.
Calgary's ant season typically runs from April through September, with activity peaking in June and July. The most common species found in Calgary homes include carpenter ants, pavement ants, pharaoh ants, and odorous house ants. Each species requires a different treatment approach: carpenter ants need nest location and direct treatment, pavement ants respond well to perimeter baiting, and pharaoh ants require specialized baiting programs — spraying them actually makes the problem worse by causing colonies to split.
Effective ant control requires eliminating the entire colony, not just the foraging workers you see in your kitchen. Our technicians use targeted baiting systems that worker ants carry back to the colony, eliminating the queen and ending the reproductive cycle. We also identify and seal entry points, remove attractants, and create protective barriers to prevent future infestations. This comprehensive approach ensures long-term ant prevention rather than a temporary fix. Call (825) 760-5364 for a free ant control quote.
Ant Control Calgary — FAQ
How much does ant control cost in Calgary?
Ant control typically starts at $250-$450 depending on the ant species, property size, and severity of the infestation. Carpenter ant treatment may cost more due to the need for nest location and structural inspection. Treatment includes inspection, targeted baiting, perimeter treatment, and prevention advice. For a free quote specific to your situation, call (825) 760-5364.
How long does ant treatment take to work?
Baiting systems typically eliminate the colony within 7-14 days, as worker ants need time to carry the bait back to the queen. You may see increased ant activity in the first few days as ants are attracted to the bait — this is normal and means the treatment is working. Complete colony elimination is typically achieved within 2-3 weeks.
Are ant treatments safe for pets and children?
Yes. We use targeted baiting systems and perimeter treatments applied to cracks and crevices — not broadcast spraying. Baits are placed in tamper-resistant stations, and liquid treatments are applied to areas where ants travel, not living spaces. We provide clear re-entry instructions and offer eco-friendly options upon request.
Do you treat carpenter ants differently?
Yes. Carpenter ants require a specialized approach because they nest in wood. Our technicians locate the nest, assess structural damage, and apply direct treatment to the colony. We also inspect for moisture issues that attract carpenter ants, as they prefer water-damaged wood. Carpenter ant treatment includes a follow-up inspection to ensure complete elimination.
How do I prevent ants from coming back?
Seal cracks and entry points around your foundation, keep food in sealed containers, eliminate moisture sources, trim vegetation away from your home's exterior, and keep kitchen surfaces clean. We provide detailed prevention recommendations after every treatment, and quarterly maintenance treatments are available for properties with recurring ant problems.
