Pest control specialist Pharaoh ants
The pharaoh antPharaoh antis the most difficult ant species to eliminate in residential and commercial settings in Quebec. Unlike other species that have only one queen, a pharaoh ant colony can have from 15 to 200 queens and up to 300,000 individuals. They live only inside heated buildings and spread quickly between walls, floors, ceilings, and neighboring apartments.
Our professional method relies on delayed-action baits that worker ants bring back to all queens simultaneously. No aerosols are used—improper treatment causes the phenomenon of sprouting (division of the colony into satellite sub-colonies), which worsens the infestation.
✅ Full inspection – ✅ Health Canada professional bait – ✅ Guaranteed multi-visit plan
Why are pharaoh ants the hardest to eliminate
A pharaoh ant infestation is never resolved in less than a month. Spraying a common insecticide triggers a defense mechanism unique to this species: the colony fragments into scattered sub-colonies within walls, false ceilings, and conduits, multiplying the problem by 5 to 10.
Our professional approach rests on three pillars:
1. Precise identification of the species (often confused with thief ants or the sugar ant).
2. Non-repellent gel bait placed on the activity trails — the workers bring them back to all the queens in 7 to 14 days.
3. Plan multiple visits 4 to 8 weeks to break the reproductive cycle and reach the new emerging workers.
Each intervention is tailored to the type of building: house, condo, rental property, restaurant, hospital, school, or clinic.
Insecticide gel treatment
Non-repellent bait gel is the only effective method against Pharaoh ants. Workers carry it back to all the queens (15-200 per colony) through trophallaxis. No aerosols – spraying fragments the colony and worsens the infestation.
Preventive inspection and sealing
Our technicians inspect cracks, entry points, wet areas and nesting sites. Where possible, we recommend sealing access points to greatly reduce the risk of reinfestation.
Targeted spraying and spot treatment
We apply professional products approved by Health Canada to strategic areas such as baseboards, cracks, garages, foundations, windowsills and other points of activity. Treatment is targeted to maximize effectiveness while limiting unnecessary exposure.
Long-lasting professional baits
Our professional gel baits are used in residential, hospital, school, and commercial settings. Targeted application in areas inaccessible to children, without contact with food surfaces.
Why choose us
Why a Pharaoh specialist is essential
An exterminator experienced with Pharaoh ants is essential because this species is also a vector of pathogens in residential settings. WHO and Health Canada Studies: Pharaohs Carry at Least 12 Pathogenic BacteriaSalmonella, Staphylococcus, Pseudomonas, E. coli) on their cuticle. This is why their presence is prohibited in hospitals, long-term care facilities, and food establishments.
Our goal: eliminate 100 % queens, break the reproductive cycle, and certify the building as pest-free.
Our advantages:
👨🔬 Certified Professional Bait Technicians
Specific training on Pharaoh ant and differential identification (vs thief ants, odorous house ants, carpenter ants).🎯 Targeted non-repellent queen baitsNo aerosol — only Health Canada approved insecticide gel that worker bees bring back to all queens in 7 to 14 days.
🏢 Real Estate and Commercial Specialization
Experience in multi-unit residential buildings, restaurants, hospitals, clinics, daycares – places where cockroaches proliferate the most.💯 Plan multiple visits + follow-up
The pharaoh requires 2 to 4 interventions over 4 to 8 weeks. Our structured plan includes post-treatment follow-up and elimination certification.
Our protocol in 4 steps
The protocol for eliminating pharaoh ants relies on 4 steps: mapping trails, choosing bait, strategic placement, and 2-4 follow-up visits. The minuscule size (1.5 to 2 mm) and discretion of this species make visual identification very difficult for a non-specialist.
A single visibly contaminated kitchen or bathroom often reveals an established colony in the walls and ducts for 6 to 12 months.
How identify a pharaoh ant
Physical characteristics (vs. other ants)
The pharaoh antPharaoh antis the smallest household ant in Quebec, not exceeding 2 mm. Here's how to recognize it precisely:
- Size 1.5 to 2 mm — about the size of a sugar grain.
- Color pale yellow to reddish-brown, with a darker abdomen.
- Shape Slender body, two distinct knots on the petiole, antennae with 12 segments ending in a 3-segment club.
- Wedding flight None—the pharaoh never flies. Reproduction by mating inside the nest.
- Activity 24/7, year-round (tropical species, dependent on indoor heat).
- Trails very organized, along baseboards, cracks, electrical conduits and plumbing.
The pharaoh does not see never outside in Quebec. Its presence always indicates a colony established in the building.
Signs of an active infestation
- Trails of small yellow ants in the kitchen, bathroom, near electrical outlets or hot water pipes.
- Focused activity near sweet and fatty food sources (sugar, honey, jams, butter, fats, meats).
- Pharaohs attracted to humidity and heat behind appliances, under sinks, near water heaters.
- Simultaneous appearance in multiple rooms — a sign that the colony is already well established within the walls.
- Neighbors in the same building also infested — the pharaoh passes through the adjoining walls via the conduits.
- Persistence despite cleaning and the traps of commerce — the colony remains hidden within the building's structure.
What health risks for the occupants
The pharaoh ant is classified as a public health pest by Health Canada due to its role as a mechanical vector of pathogenic bacteria. Unlike carpenter ants causing property damage, the pharaoh contaminates food, medical supplies, and kitchen surfaces.
Documented pathogens on pharaohs:
- Salmonella (gastroenteritis, typhoid fever); ;
- Staphylococcus aureus (skin infections, foodborne illnesses); ;
- Pseudomonas aeruginosa Hospital-acquired infections ;
- Streptococcus, Clostridium, Escherichia coli ;
- mold and yeast spores.
That's why the presence of pharaohs is Strictly forbidden in hospitals, CHSLDs, daycare centers, dental clinics, restaurants, and food establishments. An untreated infestation in a rental building can lead to complaints to the Tribunal administratif du logement (TAL) and claims for unsanitary conditions.
Why the The spray NEVER works against the pharaohs
Spraying an insecticide on pharaoh ants is the most costly mistake you can make. This species triggers a defense mechanism called sprouting Under chemical stress, queens disperse and establish new sub-colonies in untreated areas (false ceilings, crawl spaces, other apartments). A single spray can cause an infestation to go from 1 colony to 5-10 sub-colonies in 2 weeks.
The only effective method is non-repellent bait:
- the workers accept the bait as food (sugar, protein, or fat depending on the season); ;
- they bring it back to the nest and distribute it by trophallaxis (mouth-to-mouth food exchange) ;
- All queens receive a lethal dose within 7 to 14 days; ;
- The entire colony dies in 4 to 8 weeks.
Our protocol includes:
- Mapping of activity trails by setting up observation baits; ;
- choice of bait adapted to seasonal food preference ;
- strategic placement at trail intersections ;
- 2 to 4 follow-up visits over 4 to 8 weeks; ;
- Written certification of complete elimination after final inspection.
Prevent the return of Pharaohs after treatment
Pharaoh ant prevention relies on eliminating food sources and sealing adjoining entry points. Since this species depends entirely on human food and indoor heat, controlling its environment is as important as initial treatment.
Recommended measures:
- store all sugary, fatty, and protein-rich foods in airtight containers (glass, waterproof plastic); ;
- Clean crumbs, honey drips, jam, and cooking grease immediately. ;
- empty the garbage daily and clean it with soapy water once a week; ;
- avoid leaving full pet bowls out all night; ;
- Seal cracks around outlets, baseboards, plumbing fixtures, and electrical conduits. ;
- repair water leaks (gaskets, faucets, drains) — dampness attracts Pharaoh ants; ;
- In a building: seal adjoining passages (ducts, joints, technical conduits).
An annual preventive inspection is recommended for residential buildings and commercial establishments at risk.

Fair questions about Pharaoh ants
The Pharaoh antPharaoh antis the smallest domestic ant in Quebec, measuring only 1.5 to 2 mm. It is pale yellow to reddish-brown, with a darker abdomen. Unlike other ants, it never flies and remains active 24/7 all year round. If you see very small yellowish ants trailing along your baseboards or in the kitchen, it is likely an infestation of pharaoh ants.
A A pharaoh ant colony can contain between 15 and 200 queens. and up to 300,000 individuals. Spraying an insecticide triggers the phenomenon of sprouting The colony divides into satellite sub-colonies scattered in neighboring walls, ceilings, and apartments. Improper intervention can multiply the problem by 5 to 10 in a few weeks. Only professional non-repellent baits, brought back to all queens by workers, can eliminate the entire colony.
The price usually ranges between 350 $ and 1,200 $ Depending on the number of affected rooms, the type of building, the need to intervene in several neighboring apartments, and the number of follow-up visits (2 to 4 generally). Pharaoh ants are more expensive to treat than other ants because their treatment necessarily involves multiple visits over 4 to 8 weeks. A preliminary inspection will establish a precise estimate.
The complete elimination of a pharaoh ant colony takes 4 to 8 weeks with a professional bait protocol. Workers bring the bait back to the queens within 7 to 14 days, but because the colony has multiple queens and new workers are continuously emerging from eggs, multiple visits are required to break the full reproductive cycle.
Yes. Health Canada classifies the pharaoh ant as public health nuisance. This species mechanically carries at least 12 pathogenic bacteria on its cuticle: Salmonella, Staphylococcus aureus, Pseudomonas, E. coli, Streptococcus, Clostridium. This is why its presence is prohibited in hospitals, long-term care facilities, daycare centers, and food establishments.
No, absolutely not. Spraying an insecticide on pharaoh ants triggers their defense mechanism via sprouting qui fait éclater la colonie en sous-colonies dispersées. Les pièges traditionnels n’atteignent que les ouvrières visibles (moins de 5 % de la colonie) et laissent les reines intactes. Seuls les appâts professionnels non répulsifs en gel, distribués par trophallaxie aux reines, peuvent éliminer une colonie de pharaons.
Pharaoh ants never live outdoors in Quebec; they are of tropical origin and die below 18°C. They get into buildings via: infested merchandise (groceries, deliveries), potted plants, second-hand furniture, and especially through the party walls of neighboring apartments. In buildings, infestations spread between floors via electrical conduits, plumbing shafts, and foundation joints.
Yes ✅ Gel baits used against pharaoh ants are approved by Health Canada and applied in tiny quantities in inaccessible areas: behind appliances, in crevices, under sinks, in electrical conduits. No aerosols or surface liquid treatments. The method is designed specifically for sensitive environments: hospitals, daycares, clinics.
