Mosquito control program set to begin

Point Edward, ON – Lambton Public Health (LPH) is announcing that catch basin larviciding, designed to control mosquito larvae and reduce the incidence of West Nile virus (WNV) in Lambton County, is set to begin this week.

The St. Clair Region Conservation Authority has been contracted by LPH to conduct larval surveillance and apply larvicide under the Ministry of Environment, Conservation and Parks larviciding permit. Methoprene (Altosid) in pellet formulation (Pest Control Products Act #21809) will be placed in the catch basins.

Vehicles used for larviciding will be equipped with a rooftop flashing yellow light and signs to identify them as part of the West Nile virus program, as well as to encourage other drivers to use of caution since the vehicle makes frequent stops.

Larviciding is one measure used to impede mosquito breeding and control adult mosquito populations. Lambton Public Health also encourages residents to:

  • Remove stagnant water around your property
  • Keep eaves clear of debris
  • Drain water from containers or toys
  • Use insect repellent containing DEET or Icaridin when outside during peak hours (dawn and dusk) or in locations where mosquitos are most active

West Nile virus Surveillance

Mosquito trap surveillance and testing will begin in early July. Positive findings will be reported and health system monitoring of human cases is ongoing.

Lambton Public Health would like to remind the public that there is no collection of dead birds for West Nile virus surveillance.

If residents find a dead bird on their property, they are asked to dispose of it properly using gloves or a bag to pick up the dead bird, followed by discarding the bag and the bird into a garbage container to be disposed of with their regular garbage.
