6 Signs You Have an Ant Infestation

🐜

Ant Trails

Lines of ants marching along baseboards, countertops, or windowsills — following pheromone trails laid down by scout ants leading to food sources.

🪵

Sawdust Piles

Small piles of fine wood shavings (frass) near baseboards, windowsills, or structural wood — a telltale sign of carpenter ant nesting activity.

🔊

Rustling in Walls

Faint rustling or crackling sounds inside walls, especially at night, caused by carpenter ants excavating galleries in wood framing.

🥏

Winged Ants Indoors

Swarms of winged ants emerging inside your home, especially in spring, indicate a mature colony is nesting within the structure.

🏔

Soil Mounds

Small mounds of displaced soil along driveways, sidewalks, and foundation walls created by pavement ants building their nests underground.

🍴

Ants in Food Areas

Clusters of ants around pet bowls, fruit bowls, sugar containers, and garbage bins — drawn by sweet, greasy, and protein-rich food sources.

Understanding Ontario's Ant Species

Ontario is home to dozens of ant species, but a handful are responsible for the vast majority of infestations in homes and businesses. Identifying the species is the critical first step in effective treatment because each type responds to different bait formulations and treatment strategies.

Carpenter Ants — Ontario's Most Destructive Ant

Carpenter ants (Camponotus species) are the largest ants in Ontario, with workers ranging from 6 to 13 mm. Unlike termites, they do not eat wood — they excavate it to create smooth, clean galleries for nesting. Over years, this hollowing can weaken floor joists, wall studs, roof rafters, and window frames, leading to costly structural repairs.

Carpenter ants prefer damp, softened wood, making homes with moisture problems especially vulnerable. They commonly nest in areas around leaky roofs, bathrooms, dishwashers, and poorly ventilated crawl spaces. A mature colony can contain 3,000 to 10,000 workers and often establishes satellite colonies throughout the structure, making complete elimination essential.

Pavement Ants — Ontario's Most Common Invader

Pavement ants (Tetramorium immigrans) are small, dark-brown ants about 3 mm long. They nest in soil beneath sidewalks, driveways, and foundations, and enter homes through cracks in concrete slabs and basement walls. While they do not cause structural damage, they contaminate food and can be extremely persistent once established inside a home.

Colony-Based Treatment Approach

Spraying visible ants with off-the-shelf products kills only the foragers you can see — typically less than 10% of the colony. The queen continues to lay eggs, and the colony quickly recovers. ZeroBite uses professional-grade bait systems specifically formulated to be carried back to the colony and shared with the queen, larvae, and workers through a process called trophallaxis. This destroys the entire colony from within.

For carpenter ants, we combine baiting with targeted wall-void injections using residual dust formulations that reach galleries hidden deep inside structural timbers. We also identify and address moisture issues that attracted carpenter ants in the first place, reducing the risk of future infestations.

Carpenter Ant Fact

Carpenter ants do not eat wood — they excavate it to build nesting galleries. A mature colony can contain 3,000 to 10,000 workers and often establishes satellite colonies throughout the structure, making professional colony-level treatment essential.

Our Ant Treatment Checklist

  • Species identification and colony location assessment
  • Targeted bait station placement along foraging trails
  • Wall-void dust injection for carpenter ant galleries
  • Exterior perimeter treatment to block re-entry
  • Moisture source identification and recommendations
  • Follow-up visit to confirm colony elimination
  • 30-day guarantee with free retreatment if ants return

4 Steps to Ant-Free Living

1

Species Identification

Our technician identifies the ant species, locates trails, and determines whether colonies are nesting inside or outside the structure.

2

Targeted Baiting

We place species-specific bait stations along foraging trails. Ants carry the bait back to the colony, spreading it to the queen and workers.

3

Nest Treatment

For carpenter ants, we inject residual dust directly into wall voids and nesting galleries. Exterior perimeter treatments block re-entry.

4

Follow-Up & Prevention

We return to confirm colony elimination and provide recommendations for moisture control, landscaping, and sealing to prevent future infestations.

Ant Extermination FAQ — Ontario

Yes. Carpenter ants do not eat wood like termites, but they excavate galleries inside structural timbers, joists, and wall studs to build their nests. Over time, this hollowing weakens the wood and can compromise the structural integrity of your home. Damage from carpenter ants often goes unnoticed for years because the galleries are hidden inside walls, making regular inspections important.

Ants enter homes through tiny cracks in foundations, gaps around windows and doors, openings around plumbing and electrical lines, and along tree branches or shrubs touching the building. Scout ants leave pheromone trails that guide thousands of colony members to food and water sources inside your home. Sealing entry points and trimming vegetation away from the house helps reduce access.

Ant extermination in Ontario typically costs between $200 and $800 depending on the species, the size of the colony, and the extent of the infestation. Carpenter ant treatments tend to be more expensive due to the need for wall injections and follow-up inspections. ZeroBite provides free inspections and upfront quotes before any work begins.

Most ant colonies can be eliminated within 1 to 3 weeks using professional bait systems. The bait is carried back to the colony by foraging ants and shared with the queen and other members, destroying the colony from within. Carpenter ant treatments may take slightly longer due to the need to locate and treat satellite colonies within the structure.

What Ontario Homeowners Say About Our Ant Service

★★★★★
“We had carpenter ants in our bathroom walls for what turned out to be years. ZeroBite found the main colony and two satellite nests, treated everything, and the problem was gone within two weeks. Saved us from much worse damage.”

★★★★★
“Pavement ants were constantly getting into our kitchen no matter what we tried. The technician placed bait stations and within a week the trails were gone completely. Great service and fair pricing.”

Michael B. Ontario
★★★★★
“Really appreciated that they identified the species first and explained why the bait approach works better than spraying. The eco-friendly approach was important to us with young kids at home. Problem solved in about 10 days.”
