Pools and control of biting insects

Pool maintenance is compulsory from May 15 to September 15, in order to curtail the reproduction of mosquitoes harmful to your health and quality of life, as well as the safety of young children. Your pool must remain accessible for inspection by the green patrol.

Eliminate all sources of stagnant water that foster the reproduction of mosquitoes whose stings could transmit the West Nile Virus if they have fed off the blood of an infected bird. Pay special attention to decorative fountains, children’s toys, wheelbarrows with water, birdbaths or any other receptacle left outdoors.


The West Nile Virus is here. You must protect yourself!

The West Nile Virus, or WNV, is transmitted by mosquitoes. While in most cases, it is benign, it can cause serious diseases in people of all ages, regardless of the state off their health. In 2012, a substantial increase in the number of mosquitoes carrying this virus was noted, and several cases of infections among humans were reported in Québec. In August 2013, the firm of GDG Environnement detected the presence of this virus in samplings of mosquitoes from Rosemère.

To protect yourself against the WNV:

  • Wear light-coloured clothing that covers the arms and legs.
  • Use insect repellent according to the manufacturer’s instructions.
  • Keep screens and screen doors closed.
  • Eliminate mosquitoes that are indoors.
  • Be particularly vigilant in damp and shaded areas during the day, as well as evenings and nighttime, even if mosquitoes are not visible or annoying.

It is also important for you to ensure that areas around your house do not favour the reproduction of mosquitoes. A regular inspection will allow you to empty water that may have accumulated in toys, pails, tools and garden furniture. Inspecting and cleaning eavestroughs can also help you avoid mosquitoes at home.
