Ant control

Ant Control Services

Ant problems are rarely solved on the counter. We find the nest — or the satellite nest inside your structure — and treat the colony so the trail stops for good.

What we treat

Ant control — what is covered

We treat carpenter ants, pavement ants, pharaoh ants, odorous house ants and field ants across the GTA, Hamilton, KWC, Durham & York Region.

Carpenter ants are the one to take seriously in Ontario. They nest in damp or previously wet wood — window sills, door thresholds, deck ledgers, roof leaks — and the sawdust-like shavings they push out are the clue most homeowners miss.

  • Carpenter ants nesting in damp framing, sills and deck ledgers
  • Pavement ants under interlock, driveways, patios and slabs
  • Pharaoh and odorous house ants in kitchens and bathrooms
  • Exterior colonies pushing indoors in spring and after rain
  • Repeat trails along baseboards, plumbing lines and window frames
  • Commercial kitchens, cafés and food-handling areas

Signs of infestation

What to look for

  • Trails of ants along counters, baseboards or the exterior foundation
  • Coarse sawdust-like shavings near window frames, decks or door sills
  • Large black ants indoors in spring, especially at night
  • A faint rustling in a wall void with carpenter ant activity
  • Winged ants indoors, which can indicate a nest inside the structure

Our process

Inspection, treatment, exclusion, follow-up

  1. 1Species identificationTreatment differs sharply between pavement, pharaoh and carpenter ants, so we identify before we treat.
  2. 2Trail and nest tracingWe follow foraging routes to locate the nest or satellite nest rather than treating symptoms.
  3. 3Colony treatmentBaiting and targeted application designed to be carried back to the colony.
  4. 4Moisture and entry reviewWith carpenter ants we identify the damp wood and access points that made the site attractive.
  5. 5Follow-upWe confirm the trail has collapsed and treat any satellite activity that appears.

Why DIY often fails

What goes wrong without a licensed technician

  • Store sprays kill foragers you can see but leave the queen and nest untouched
  • Repellent products split colonies and create new satellite nests indoors
  • Bait placed in the wrong spot, or with the wrong sugar/protein mix, gets ignored
  • Carpenter ant damage keeps progressing while surface spraying continues
  • The moisture problem feeding the nest is never found or fixed

Prevention

Keeping it from coming back

  • Fix leaks, damp sills and poor drainage against the foundation
  • Keep mulch, soil and firewood away from the wall line
  • Replace water-damaged wood rather than painting over it
  • Trim branches that touch the roof or siding
  • Seal gaps around door thresholds and utility entries

Quick answers

Frequently asked questions

How long does ant treatment take to work?

Trails usually drop within a few days as bait is carried back to the colony. Carpenter ant work can take two to three weeks to fully collapse the nest, which is normal.

Should I stop cleaning the trail?

Leave visible bait placements alone and avoid spraying cleaner over them — the ants need to keep travelling to carry the bait home.

How do I know if they are carpenter ants?

Carpenter ants are large, usually black, and leave coarse shavings that look like pencil sharpenings. Pavement ants are small and trail in numbers along cracks and edges.

Do carpenter ants damage a house like termites?

They do not eat wood, they hollow it out to nest, and they prefer wood that is already damp. Damage is slower than termite damage but still worth addressing early.

What areas do you cover?

We serve Toronto and the GTA, Hamilton and Burlington, Kitchener-Waterloo-Cambridge and Guelph, Durham Region including Oshawa, Whitby, Ajax and Pickering, and York Region including Markham, Richmond Hill, Vaughan, Newmarket and Aurora.

Do you offer same-day or emergency service?

Yes, where the schedule allows. Stinging insects near entrances, rodents in food premises and bed bugs in occupied bedrooms are prioritised. Call 365-293-5253 for the earliest opening.

Is the work guaranteed?

Every treatment program comes with a written service guarantee. If activity persists inside the guarantee window, we return at no additional charge.
