    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).
