Pharaoh ants, an invasive species in buildings.

In Montreal, infestations of pharaoh ants in buildings represent a serious and often underestimated problem. This highly invasive species directly establishes itself within the building structure—walls, ceilings, ducts, and crevices—and then rapidly spreads from one unit to another. Very difficult to eradicate, it requires a methodical, rigorous intervention tailored to the reality of multi-unit buildings.

See technical sheet

Pharaoh Ants (Monomorium pharaonis)

The use of repellent insecticides only exacerbates the situation. These products disperse the colonies within the building structure and promote the multiplication of nests and the infestation of other units.


Conversely, a responsible, precise intervention based on a targeted baiting strategy addresses the problem at its source, and that is our specialty.


Complete inspection of the premisesInspection and precise identification of the species. Assessment of the degree of infestation, determination of affected and at-risk units. Fast and professional service.
Tenant awareness and collaborationWe raise awareness among tenants to ensure their cooperation and maximize the effectiveness of treatments.
Establishing a targeted fight strategyAfter gathering all the necessary information about the species, the affected units, and the at-risk sectors, we implement a precise control strategy that outlines the steps for treatment, the locations to target, and the expected collaboration from tenants, in order to sustainably eliminate pharaoh ants from the building.
Housing and building structure processingThe treatment involves targeting colonies, both in the housing and within the building structures, using carefully selected and strategically positioned baits.
Scheduled follow-ups until zero confirmed attendanceTo ensure the eradication of Pharaoh ant populations throughout the building, a minimum of two follow-ups will be scheduled after the initial treatment. These control visits are essential to verify the results obtained, target persistent activity hotspots, adjust the intervention strategy, and maintain pressure on the colonies until their sustainable elimination.
Intervention guaranteeWe offer a total elimination guarantee for pharaoh ant colonies, with extended coverage available to ensure continued protection.
