Comprehensive approach extermination and prevention
A spider infestation requires a comprehensive approach: diagnosis, treatment, and prevention.
Our approach is based on sustainability and safety.
The types of spiders that we process in Montreal
Wolf spiders (Lycosidae)
Fast, on the ground, visible near baseboards and garages. Enter during seasonal changes.
Cellar spider (Agelenidae)
Weave webs in corners, basements, and poorly ventilated spaces.
Common household spiders
Found in kitchens/bathrooms, attracted by moisture and the presence of insect prey.
Warning signs: multiple webs, threads anchored to window frames, accumulation near light fixtures = proliferation.
Our spider extermination process (clear and transparent)
Understanding your problem: signs and causes
Signs of infestation
- Recurring webs, clusters of threads, egg sacs, insect remains, increased seasonal presence.
Common causes in Montreal
- Damp basements, unsealed cracks, damaged mosquito nets, outdoor lighting attracting prey.
Prevent the return of spiders (expert advice)
Reduce humidity (dehumidifier/basement, bathroom ventilation).
Seal cracks & joints (windows, thresholds, cable outlets).
Maintaining the exterior (trim shrubs against the facade, limit lighting that attracts insects).
Clean the screens after treatment to break the anchor points.
When combined with our treatment, this protocol reduces >80 % reinfestations.
