A line of ants across the kitchen counter is rarely the real problem — it's a symptom of a colony hidden in a wall, under a slab, or out in the yard. Terra13's ant extermination service, from Terra13 Pest Control, targets that colony directly: we identify the species, trace the trail back to the nest, eliminate the queen, and seal the entry points so the trail doesn't come back.
Spraying the ants you can see feels satisfying, but it often makes things worse — it kills a handful of foragers while the colony keeps producing thousands more, and some species even split into new colonies when they feel threatened. Colony-focused baiting works with the ants' own behaviour instead of against it.
Winnipeg homes deal with several very different ant species, and the right treatment depends entirely on which one you have. Carpenter ants tunnel into damp wood and can cause structural damage; pavement and sugar ants are nuisance foragers; pharaoh ants require careful baiting because sprays scatter them.
The Ant Species We Treat in Winnipeg
Correct identification is the whole game with ants — it decides the bait, the placement, and whether the wood in your home is at risk. The species Terra13 handles most across Winnipeg and Manitoba include:
- Carpenter ants — large black ants that excavate galleries in moist or damaged wood; the ones most likely to threaten structure.
- Pavement ants — small dark ants that nest under slabs, driveways, and foundations and forage indoors for food.
- Sugar / odorous house ants — tiny ants drawn to sweets that give off a coconut-like smell when crushed.
- Pharaoh ants — pale indoor ants that must be baited, never sprayed, because sprays cause them to bud into multiple colonies.
- Field, thief, and citronella ants — outdoor and occasional-invader species that Terra13 confirms during the inspection.
How Terra13 Treats an Ant Infestation
After confirming the species, technicians place Health Canada–approved gel and granular baits along active trails and near the nest. Foragers carry the bait back and feed it to the colony and the queen, collapsing the nest from the inside over the following days.
Where carpenter ants or a structural nest is involved, treatment also targets voids and galleries directly, and we identify the moisture or wood issue drawing them in. The visit finishes with entry-point recommendations — sealing gaps around pipes, sills, and foundation cracks — so new colonies can't re-establish the trail.
