Most GTA homeowners assume termites are a southern problem. They are not. Subterranean termites are established in the GTA, and they have been found in homes across Toronto, Mississauga, Brampton, andHamilton. Here is what every GTA homeowner needs to know.
Yes, Toronto Has Termites
Subterranean termites (Reticulitermes flavipes) have been documented in southern Ontario for decades. They are established in the GTA and cause damage every year.
Warm winters and new construction in previously rural areas have expanded the termite range. They are not going away.
Where They Are Found
Termites in the GTA have been documented in:
- Toronto, particularly older neighbourhoods
- Mississauga, especially newer developments
- Brampton
- Hamilton and surrounding areas
- Along Lake Ontario corridor
Signs of Termite Infestation
- Mud tubes. These are the most visible sign. Termites build mud tubes on foundations to travel between soil and wood. Look for pencil-width tubes on concrete foundations, especially where the foundation meets the soil.
- Hollow-sounding wood. Tap on wooden beams, door frames, and baseboards. If it sounds hollow, termites may have eaten the interior.
- Discarded wings. In spring (typically April-May), swarmer termites shed their wings near windows and doors. If you find discarded wings, you have an established colony.
- Swarmers. Winged termites emerging from wood or soil. They look like winged ants but have straight antennae and equal wing pairs.
- Wood damage. Termites eat wood from the inside out. The surface may look intact while the interior is hollow.
Termites vs Carpenter Ants
It is easy to confuse carpenter ants with termites. Here is how to tell the difference:
Termites:
- Straight antennae
- No waist (body is straight)
- Equal-sized wing pairs
- Eat wood (damaged wood has layered mud)
- Often found in soil
Carpenter ants:
- Bent antennae
- Distinct waist
- Wings may be different sizes
- Excavate wood (no mud)
- Often found dry wood
Treatment Approaches
1. Soil Treatment (Liquid Barrier)
Trenches are dug around the foundation and termiticide is applied to create a chemical barrier. This prevents termites from entering the home.
- Most common approach
- Cost: $500 to $800
- Effective for 5-10 years
2. Bait Systems
Bait stations are installed around the property. Termites feed on the bait and carry it back to the colony, eventually eliminating it.
- Less invasive
- Cost: $800 to $1,500+
- Requires ongoing monitoring
What to Do If You Suspect Termites
- Do not disturb the suspected area
- Do not use DIY treatments
- Call a licensed termite professional
- Get multiple quotes
- Review the inspection report carefully
Insurance Coverage
Most standard home insurance policies do not cover termite damage. This is considered preventable damage that falls on the homeowner. The cost of treatment and repair comes out of pocket.
Some policies offer optional coverage. Check your policy.
Cost Summary
- Inspection: Often free for new quotes
- Soil treatment: $500 to $800
- Bait system: $800 to $1,500+
- Full treatment + repair: $1,000 to $5,000+
Prevention
- Keep firewood at least 20 feet from the house
- Fix moisture problems around the foundation
- Remove wood debris near the foundation
- Ensure proper grading away from the foundation
- Inspect annually
