WHAT ATTRACTS INSECTS
Why Ants Enter Homes
Ants usually come inside for food, moisture, and shelter, through gaps most homeowners never notice.
Food Crumbs
Open food, sticky spills, pet bowls, and crumbs left along kitchen counters give foraging ants a scent trail straight to your pantry.
Moisture Sources
Leaky pipes, damp wood, bathrooms, and basements attract moisture-seeking ant species like carpenter ants and odorous house ants.
Entry Gaps
Cracks near windows, doors, foundations, and utility lines are all it takes. Worker ants can exploit gaps smaller than a coin to get inside.
Warm Shelter
Cold or rainy weather pushes ant colonies toward warmer indoor spaces, including wall voids, behind baseboards, and under flooring.
Outdoor Nesting Areas
Mulch, soil, pavement cracks, and woodpiles close to your foundation give ant colonies a staging point right next to your home’s entry gaps.
SPECIES LIBRARY
Common Ant Species
Identifying the ant species correctly determines the treatment. Carpenter, pavement, pharaoh, and odorous house ants all respond to different baiting methods.
Thief Ants
Tiny yellow-to-brown ants known for nesting near other ant colonies and stealing food and larvae. Often confused with pharaoh ants due to their small size, but usually found in dry, hidden areas away from moisture.
Pharaoh Ants
Pale yellow ants that thrive indoors year-round, especially in apartments and multi-unit buildings. Disturbing their trails with over-the-counter spray can cause the colony to bud and spread rather than die off.
Pavement Ants
Small, dark brown ants that nest under slabs, driveways, and foundations. These are typically the ants seen marching in a visible trail along kitchen counters and windowsills.
Odorous House Ants
Named for the rotten-coconut smell they release when crushed. They build large colonies with multiple queens, which is why single-spot spraying rarely solves the problem.
Carpenter Ants
The most damaging species locally. Carpenter ants excavate wood to build their nest rather than eat it, and can weaken structural framing over time if left untreated. Sawdust-like frass near baseboards or window frames is a common warning sign.
Argentine Ants
Highly invasive and known for forming supercolonies with multiple queens and interconnected nests. Argentine ants are aggressive competitors that can quickly overwhelm other ant species in a yard.
WARNING SIGNS
Signs You Have an Ant Infestation, Not Just a Few Strays
A couple of ants on the counter is normal. These signs point to an established colony nearby.
Repeated sightings in the same spot
Seeing ants in the same area over several days, not a one-off, usually means a visible ant trail leading back to an active nest.
Sawdust-like frass near wood
Small piles of wood shavings near window sills, baseboards, or decks are a carpenter ant warning sign, since they excavate wood to build galleries.
Rustling sounds inside walls
A faint, dry rustling noise inside wall voids can indicate carpenter ant activity, particularly at night.
Visible ant trails
A line of worker ants moving in formation toward a food or water source means the colony has already established a reliable route into your home.
Winged ants indoorsWinged ants indoors
Seeing ants with wings inside the house, not just outside, can signal a mature colony preparing to swarm and expand.
Our Process
Our Pest Control Process
our process
Our Ant Control Process
Inspection
We inspect your property for ant trails, nesting sites, and entry points around foundations, window frames, and utility lines. This step identifies whether you are dealing with carpenter ants, pavement ants, pharaoh ants, or odorous house ants.
Identification
Correct species identification determines the treatment plan. Carpenter ants require wood void treatment, while pharaoh ants and odorous house ants respond better to targeted baiting that reaches the full colony.
Treatment
We apply colony-level ant baiting and targeted spot treatment at nests, trails, and entry points, so the colony is eliminated at the source instead of just the worker ants you see on the surface.
Why Choose Us
Why Choose Our Ant Control Service
We inspect, identify the ant species, and treat the colony at its source for lasting ant control across the GTA.
Expert Technicians
Our licensed exterminators are trained to identify carpenter ants, pavement ants, and pharaoh ants accurately, since misidentifying the species is the most common reason DIY ant treatments fail.
Safe Targeted Solutions
We use precise ant baiting and gel application near nesting sites and trails, keeping treatment family and pet safe while still reaching the queen and the rest of the colony.
Effective Treatments
Using Ministry of Environment registered ant control products, we target the nest rather than just the visible trail, preventing the colony from budding into a bigger problem.
Satisfaction Guarantee
If ants return to a treated area between visits, we come back and re-treat it at no extra cost, backed by our satisfaction guarantee.
Preventive Strategies
We identify the entry gaps, moisture sources, and outdoor nesting areas near your foundation that attract ants, and provide a clear prevention plan to stop them coming back.
Comprehensive Approach
From inspection through species identification, colony treatment, and follow up monitoring, our ant control process is built to break the infestation cycle completely, not just clear the surface activity.

FAQs
Pest Control FAQs
What causes ants inside my home?
Ants usually come inside searching for food, moisture, or warm shelter. Crumbs, spills, damp areas near sinks or bathrooms, and small gaps around windows and foundations are the most common entry points.
Are ants dangerous in Canada?
Most common household ants in the GTA, like pavement ants and odorous house ants, are more of a nuisance than a health risk. Carpenter ants are the exception, since they can cause structural wood damage if left untreated.
How do you treat an ant infestation?
Effective ant control means treating the colony, not just the visible trail. Professional baiting placed at entry points and nesting sites reaches the queen and the rest of the colony, which surface sprays don't do.
Can I remove ants myself?
Store-bought sprays can kill visible worker ants but often push the colony to relocate or split into multiple nests, particularly with pharaoh ants. Targeted baiting is more effective for full colony removal.
How long does ant control take?
Most ant baiting treatments show a noticeable drop in activity within a week to ten days, as worker ants carry the bait back to the colony. Full elimination timelines depend on colony size and species.
Do ants come back after treatment?
They can, especially if entry points and outdoor nesting areas near the foundation aren't addressed. That's why our service includes prevention guidance and a satisfaction guarantee covering the treated area.
