Data from the City of Montreal provides a snapshot of where bed bug infestations are most frequently reported. According to the most recent public data from 2025, the Plateau-Mont-Royal and Ville-Marie boroughs continue to record the highest number of reported cases.
The city's public health authority, the CIUSSS du Centre-Sud-de-l'Île-de-Montréal, manages the official reporting and intervention program. Reports are typically generated from calls to 311, landlord notifications, and interventions by municipal inspectors.
While the data highlights problem areas, experts note that bed bugs are a widespread issue affecting all types of dwellings across the city, not confined to specific neighborhoods. The city advises residents who suspect an infestation to contact their borough immediately to initiate an inspection protocol.
Public health officials emphasize that bed bugs are not linked to unsanitary conditions but are efficient hitchhikers, easily transported in luggage, furniture, and clothing. The city's website provides resources on prevention and the official steps for eradication, which legally require cooperation between tenants and landlords.
