Baiting and barrier spray treatments for carpenter ants, pavement ants, pharaoh ants and odorous house ants. Serving homes, rentals and businesses in Edmonton, Calgary and surrounding communities.
Signs of an ant problem at your property
A few ants on the counter can be the edge of a much larger colony. Ants nest in walls, under slabs and in damp wood. These signs tell you when to look closer.
Steady trails indoors
Ants near food and sinks
Sawdust-like piles
Large black ants inside
Anthills along the foundation
Winged ants indoors
A two-part approach to ant control
Our goal is the whole colony, not just the ants on the counter. That includes nests inside walls or under the ground. Many properties benefit from a combination of baiting and spray treatment.
Ant baiting treatment
Dots of sweet or protein gel bait go along trails and nesting areas. Workers carry it back and share it with the queen. The slow-acting bait spreads through the colony until it collapses. Activity may rise briefly, then drops within one to two weeks.
Best for: Ants seen indoors, active trails and nests hidden inside walls
Ant chemical spray treatment
Spray is applied to anthills, along the exterior foundation and, if needed, indoors along baseboards and crevices. It kills on contact and leaves a residual barrier that keeps working for weeks. Indoors, allow six hours before re-entry so surfaces can dry.
Best for: Nests outside, mounds in the yard and ants getting in through foundation cracks

Why ants should be dealt with early
Ants look harmless at first, but a settled colony grows and keeps sending workers into your kitchen. Carpenter ants hollow out damp wood in walls, beams and window frames, and the damage adds up over time. Pharaoh ants can split into new colonies when disturbed, so store-bought sprays can make things worse.

Frequently asked questions
How long does ant baiting take to work?
Baiting is slow on purpose. Workers need time to carry the bait back and share it with the queen. You may see more ants for a short time as they gather it. Activity usually drops within one to two weeks as the colony collapses.
Do I need to leave my home during treatment?
Not for baiting. Bait placements are small and out of the way, and you can stay home. If an interior spray is needed, we ask you to stay out of treated rooms for six hours so surfaces can dry.
Which treatment is right for my ant problem?
Baiting suits indoor infestations, visible trails and colonies inside walls. Spray suits outdoor colonies, anthills and ants coming in through cracks. Many properties need both. The technician recommends a plan after inspecting.
Why do ants keep coming back after I spray them myself?
Retail sprays kill the workers you see but rarely reach the queen. The colony simply sends more. Some species also split into new colonies when sprayed. Professional baiting targets the whole colony, and a residual barrier helps keep new ants out for weeks.
