press release

2024 mosquito control program begins

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 including Aamjiwnaang First Nation, is set to begin this week.

Pestalto Environmental Health Services Inc. 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 (Pest Control Products Act #21809) and granule (Pest Control Products Act #22676) formulation will be placed in the catch basins.

Pestalto technicians wearing safety vests will apply larvicide by hand to roadside catch basins while on a motorized scooter that has a “Slow-Moving Vehicle” sign, along with an MECP 2024 Applicator sticker on the vehicle. Passenger vehicles may also be used and will be equipped with the same signage, along with a flashing beacon and Pestalto insignia.

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.
