Québec ants are not all treated the same way
The common species in Québec are the carpenter ant, the pavement ant and the pharaoh ant. Carpenter ants tunnel through damp wood and can weaken a structure; pharaoh ants require specific baits, because standard sprays fragment the colony and make things worse. Identifying the species is not a detail: it decides the right treatment.
How we work
1. Inspection and diagnosis
A technician examines your home or business, identifies the species, the entry points and the extent of the problem, then walks you through what they found.
2. Targeted treatment
Baits and treatments matched to the identified species, treatment of the nest and trails, and exterior applications where needed to cut off access routes.
3. Prevention and follow-up
We seal what can be sealed, give you practical advice to prevent a comeback, and return if needed. If pests come back, so do we.
FAQ
Do carpenter ants eat wood?
No, they do not eat it: they excavate it to nest, which still damages the structure over time. Acting quickly limits the damage.
Why do the ants come back every year?
If the main nest was never treated, the colony survives and starts again in spring. Treating at the source fixes it for good.
Do I need to prepare my home before the treatment?
Put food away, wipe down surfaces and keep pets clear during the visit. We send you the exact instructions beforehand.
How long does the visit take?
Most visits, inspection and treatment included, take one to two hours depending on the size of the property.
