Housing sanitation

Inspection extermination

The OMHM takes action by preventing and intervening

A major challenge

The OMHM's mission is to improve the living conditions of its tenants by offering them quality housing and services. To do so, it needs to ensure that all housing is free of vermin (like bedbugs, cockroaches, rats, mice, etc.).

However, it is important to note that vermin, and especially bedbugs, are a public health matter. Bedbugs exist practically everywhere in Montreal, in libraries, hotels, hospitals and also in private-sector housing. 

Recognizing Bedbugs and taking actions


The OMHM has undertaken several activities to prevent the propagation of vermin in its housing, in particular:

  • by having its housing inspected by an exterminator in high-risk environments. The OMHM performs around 8,000 inspections every year in buildings at risk, which lead to detecting 15% of bedbug cases;
  • preventive visit of housing of any new tenants between 30 to 45 days after their arrival (see Advice to reduce the risk of carrying bedbugs and cockroaches while moving into a new apartment);
  • preventive treatment for housing that is adjacent to a bedbug-infested property;
  • information sessions to increase awareness among tenants and show them how bedbugs, cockroaches etc. look. (watch the video)

Information sheets on vermin

The OMHM has also implemented preventive measures for its employees who have to deal with or enter infested buildings.

Vital collaboration

It is vital that everyone works together to ensure that bedbugs do not enter their homes by adopting good practices, which includes the following:

  • do not pick furniture up off the sidewalk;
  • take all necessary precautions when buying used clothing;
  • do not attempt to treat your own home using commercial products;
  • do not hoard items in your home, as this is an easy way for vermin to hide;
  • contact the OMHM Call Centre as soon as you detect a bug or as soon as you think you have bugs in your home (for example, if you see skin bites, traces of blood, etc.).

If, despite all this, you are discovering bedbugs in your apartment, the OMHM will ask for your cooperation: you will have to be present for each treatment and prepare your apartment properly. You must follow these instructions carefully to ensure the success of the treatment.


The OMHM works together with several community and institutional partners to help its tenants control pests. It is also an active partner in the sanitation project funded by the City of Montreal, which aims to accompany vulnerable households in preparing their homes.

To find out more, please refer to the general information on bedbugs provided by the City of Montreal.

Over the years, the OMHM has developed considerable expertise in controlling parasites and is regularly asked to share this expertise in seminars, including:

  • the 27th seminar of social and community housing technical staff;
  • the seminar on compulsive hoarding.
