Sarnia conducting survey to assess gypsy moth infestations

Sarnia has hired “egg counters” to help determine if another aerial spray is needed to control gypsy moths this year.

The survey by BioForest Technologies involves counting the egg masses laid on trees by adult moths to determine how widespread infestations might be this spring.

The survey is being done this month and includes the areas:

* Between Colborne Road and Christina Street, north of Exmouth.

* Blackwell Road, Telfer Road, Clarence Street, Lakeshore Road and Blackwell Glen

* Cathcart Boulevard from Murphy to Modeland Road

* The east side of Oak Acres Park.

In 2020, a helicopter twice sprayed a biological insecticide on 64 hectares (157 acres) of north Sarnia to control the moths, whose caterpillars hatch in vast numbers and can quickly defoliate trees and litter properties with droppings.
