When even the heart of public institutions is not spared…
It is a troubling finding that was recently revealed by a Radio-Canada investigation: the Grand Headquarters of the Sûreté du Québec, located on Parthenais Street in Montreal, has been struggling with a persistent cockroach infestation for several years. Between 2020 and 2025, more than 185 extermination interventions were requested, and 95% of them specifically concerned cockroaches.
At Extermination Pro-Nature, we have been asked several times to analyze and comment on the situation. Our president, Martin St-Jacques, highlighted in the report the significant health impact that such a presence in a workplace can have:
“Cockroaches carry bacteria and usually contaminate food. Their feces and urine, in large quantities, can cause respiratory problems and other reactions in the body. »
A problem that goes far beyond aesthetics
Far from being trivial, the presence of cockroaches in institutional settings raises major public health concerns. These insects can survive in the smallest cracks, feed on garbage, and quickly proliferate in ventilation systems, autopsy rooms, restrooms, and even meeting rooms.
The building, which is more than 50 years old, suffers from chronic underfunding, making curative interventions more complex and less effective. In such a context, prevention and a systematic eradication strategy become essential.
Why shock treatment is often necessary
Our team clearly indicated in the article that a shock treatment by area, floor by floor, would be essential to regain control over the infestation. This type of intervention requires not only close coordination with building managers, but also the ability to work discreetly without disrupting essential building operations.
It is this type of integrated and targeted strategy that we rigorously implement in sensitive or high-traffic buildings.
Resistant cockroaches: the challenge of recurrence
Unfortunately, this case is not isolated. A chronic infestation, when poorly controlled, leads to a well-known phenomenon: cockroach resistance to traditional products. This then requires a review of the techniques used, a rotation of biocides and the use of more advanced detection technologies. Our approach at Pro-Nature includes:
- Rotating baits of active ingredients;
- The use of smart traps;
- A thermal map of heat points likely to attract cockroaches;
- And waste management adapted to each environment.
Recognized expertise in sensitive environments
Being quoted in a report of this magnitude, broadcast by Radio-Canada, confirms the institutions’ confidence in our expertise. Whether in schools, hospitals, police stations or private companies, Extermination Pro-Nature accompanies its customers with rigor, discretion and concrete results.
What this situation teaches us
Beyond this emblematic case, this dossier highlights the importance of proactive pest management. Cockroach infestations are not limited to dilapidated kitchens or buildings. Even government buildings can be affected when prevention is neglected or infrastructure is outdated.
