    Here are the signs to watch for:

    • Sawdust or debris near walls and windows.

    • Regular trails of ants on countertops or baseboards.

    • Small insects visible at night in the kitchen.

    • Light scratching noises in the walls (carpenter ant colonies).

    If you notice these signs, contact us promptly for a free inspection in Montreal or Laval.

    Why hire a professional exterminator?

    Over-the-counter products eliminate some workers, but never the queen.
    Without professional treatment, the colony moves and doubles in size.
    Our exterminators use slow-acting baits to reach the queen and satellite nests.

    Each intervention includes:

    • accurate identification of the species; ;

    • a tailored treatment plan; ;

    • post-treatment follow-up; ;

    • a written guarantee.

    💡 Result: complete, safe, and long-lasting extermination, certified by Health Canada.

    Prevent the return of ants

    • Clean surfaces frequently and remove crumbs.

    • Seal cracks around windows, doors, and pipes.

    • Repair any water leaks (source of moisture).

    • Check foundations and wooden structures every spring.

    • Avoid accumulations of wood or leaves around the house.

    These simple actions, combined with a Extermi Pro professional treatment, prevent 90% of reinfestations.
