Mosquito Larviciding Begins July 2

Point Edward, ON – Catch basin larviciding, designed to control mosquito larvae and reduce the incidence of West Nile virus in Lambton County, begins Tuesday, July 2.

Mosquito larval surveillance has indicated the presence of mosquito larvae in catch basins across Lambton County.

Larviciding is only one measure being taken to impede mosquito breeding and control adult mosquito populations. Lambton Public Health (LPH) encourages residents to:

  • Remove stagnant water around their property
  • Keep eaves clear of debris
  • Drain water from containers or toys

To increase the level of personal protection against mosquitoes, use insect repellent (DEET) during peak times or locations where mosquitoes are active.

Reporting Dead Birds

As part of ongoing West Nile virus surveillance, the public is encouraged to report ALL dead bird sightings to LPH. Call the West Nile virus information line to report a dead bird, or for instructions to handle a dead bird:

  • 519-383-3824
  • toll-free 1-800-667-1839 ext. 3824
  • Online Form

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

About Larvaciding

The St. Clair Region Conservation Authority has been contracted by Lambton Public Health to conduct larval surveillance and apply larvicide under the Ministry of Environment and Climate Change 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 rooftop flashing yellow light, West Nile virus signs, and a “Makes Frequent Stops” caution sign. Caution is encouraged.
