OUR PROCESS

How the intervention works

  1. 1

    Complete inspection

    We identify the species, locate the main and satellite nests, and spot entry points.

  2. 2

    Treatment plan

    We determine the right strategy (baits, targeted treatment, exclusion) based on species and scale.

  3. 3

    Treatment at the source

    Baits carried back to the queen + treatment of galleries and entry points with Health Canada products.

  4. 4

    Exclusion & prevention

    Sealing, moisture and wood management to prevent return.

  5. 5

    Follow-up & guarantee

    Control visit if needed and written guarantee: we come back free if it persists.

  • No guarantee, no species diagnosis

🛡️ 514 professional treatment

  • Targeted baits carried to the queen = colony eliminated
  • Precise species and nest diagnosis
  • Concentrated Health Canada approved products
  • Treatment of satellite nests and entry points
  • Written guarantee + follow-up included

Frequently Asked Questions

How much does ant extermination cost?
The cost depends on the species, infestation scale and building type. The quote is free with no obligation: call (514) 835-2108 for a precise price tailored to your situation.
How do I know if they're carpenter ants?
Carpenter ants are large (6-13 mm), often black, and leave fine sawdust (frass) near wood. Large winged ants indoors in spring indicate a nest established in the structure. When in doubt, our inspection identifies them with certainty.
Do you offer a guarantee?
Yes. All our ant treatments come with a written guarantee. Take advantage of our extended guarantee valid until October 31, 2026 on ant treatments.
Are the products safe for my family?
Yes. We use exclusively Health Canada approved products, safe for children and pets once dry, applied in a targeted way by C5-certified technicians.
