Silverfish control in Canada
A humidity problem as much as a pest problem.
How to identify it
Teardrop-shaped silvery insects with three tail filaments; fast, wriggling movement.
Signs of an infestation
- Sightings in bathrooms, basements and storage boxes
- Irregular holes in paper, books or wallpaper
Is it dangerous?
Not harmful to people; they damage paper, books and stored goods.
Can I handle this myself?
DIY may be reasonable
Dehumidifying and decluttering often resolves light activity.
When to call a professional
Call a professional for ongoing sightings despite lower humidity.
Any pesticide used in Canada must be registered here and applied exactly as its label directs. We don't publish application instructions.
Typical professional treatment
Crack-and-crevice treatment, dusts in voids and moisture recommendations.
Visits: 1–2 visits
How to keep them from coming back
- Run a dehumidifier below 50% RH
- Fix leaks and improve ventilation
- Store paper in sealed bins
