After treatment — Carpenter Ants
The bait must travel to the main nest and satellite nests. Expect several weeks — and watch the sawdust, your best indicator.
What happens, day by day
Understanding the timeline avoids needless worry — and tells you when something is genuinely wrong.
0–4 h
Returning home
Ventilate and avoid treated areas until the products have fully dried.
3–10 days
Effect on workers
Visible activity decreases. You will find dead ants near baseboards and exit points.
2–4 weeks
Effect on the colony
The carried bait reaches the main nest and satellite nests, progressively eliminating the queen and brood.
4–8 weeks
Confirmation
No new sawdust and no traffic: the colony is gone. Damaged wood can now be replaced.
What to do in the first 48 hours
- 1
Do not clean treated areas or the baits placed along the trails.
- 2
Sweep up existing sawdust once, then watch: any NEW sawdust indicates ongoing activity.
- 3
Photograph and note the location of any new accumulation for your technician.
- 4
Start fixing moisture issues: basement dehumidifier, gutters, crawl space ventilation.
What you must not do
- Do not spray insecticide on the ants or into the galleries: this fragments the colony into satellite nests and worsens the problem.
- Do not plug galleries and holes yet — the technician must be able to track progress.
- Do not replace damaged wood before treatment is complete.
- Do not ignore a new sawdust pile: report it right away.
😌This is normal
- Activity for 1 to 2 weeks, sometimes increasing in the first days (ants are drawn to the bait).
- Dead ants near baseboards, door and window frames.
- A few isolated ants for up to 3 to 4 weeks after treatment.
📞Call us back if…
- Fresh sawdust after 4 weeks.
- Persistent crackling sounds in the walls, especially at night.
- Winged ants indoors: a sign of a mature colony swarming inside the structure.
- Wood that sounds hollow, sags or cracks.

Preventing a return
A successful treatment eliminates the current infestation. These habits prevent the next one.
- Keep basement humidity under 60 % — this is the number one factor in infestations.
- Store firewood 6 metres from the house and raised off the ground.
- Replace wood mulch with gravel along the foundation.
- Trim branches touching or overhanging the house and schedule a preventive inspection each spring.
