Mosquito Larviciding Begins June 26

This page was reviewed or revised on Wednesday, June 21, 2017 9:57 AM

Point Edward, ON - Catch basin larviciding, designed to control mosquito larvae and reduce the incidence of West Nile virus in Lambton County, begins Monday, June 26 and continues all summer.

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

Larviciding impedes mosquito larvae development, and is only one measure to reduce mosquito breeding and control adult mosquito populations. To eliminate potential breeding sites, Lambton Public Health encourages residents to remove stagnant water around their property.

Reporting Dead Birds

As part of ongoing West Nile virus surveillance, the public is encouraged to report the sighting of ALL dead birds to Lambton Public Health. To report a dead bird, or for instructions on ways to handle a dead bird, call 519-383-3824, toll-free 1-800-667-1839 ext. 3824 or online at

Mosquito trap surveillance and testing will begin 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 the County of Lambton to conduct larval surveillance and apply larvicide under the Ontario Ministry of Environment and Climate Change larviciding permit. Methoprene (Altosid) in pellet formulation (Pest Control Products Act #21809) and Methoprene, Altosid XR Briquet ingot formula, (Pest Control Product Act #27694) will be placed in the catch basins.

Vehicles used for larviciding will be equipped with a flashing yellow rooftop light, West Nile virus signs, and a "Makes Frequent Stops" caution sign. Caution is encouraged.

For more information call the West Nile virus information line at 519-383-3824, toll-free 1-800-667-1839 ext. 3824 or visit
