UPDATE: Gypsy Moth helicopter spraying scheduled for June 1
Helicopter spraying for gypsy moths over 63.5 hectares of Sarnia has been delayed again.
Friday’s spraying has been rescheduled to Monday due to weather.
Zimmer Air Services will use a twin-engine chopper to spray prescribed areas between 5 a.m. and 8 a.m. June 1, and again on June 15.
Spraying to mitigate the damage from the invasive species, over each of the four areas, should take about 15 minutes.
Impacted areas include:
– Canatara Park, Lake Chipican Drive
– Oak Acres Park
– Lakeshore Rd East of Modeland Rd
– Colborne Rd N of Michigan, S of Cathcart Blvd East to Errol Rd and Ridgewood Drive
Area homeowners were sent notices.
The city said the spraying is highly dependent on wind and weather conditions, and the development of the host tree species and the gypsy moth larva.
Members of the public are unlikely to experience any health effects, and the city said while no special precautions are necessary or required, certain measures can be taken by those living in the treatment areas.
The helicopter will be applying the biological pesticide Foray 48B Biological Insecticide Aqueous Suspension. The active ingredient in the spray is Bacillus thuringiensis which is registered under the Pest Control Products Act (Canada).
The spraying was initially set to start May 20 but was postponed at the last minute. A vote to reconsider the program was defeated by Sarnia Council at a special meeting on May 22.
The anticipated spray schedule will be published on the City of Sarnia website, as through social media feeds 48 hours prior to spraying.
Zimmer Air Services has bases in Blenheim, St. Thomas and Thunder Bay.
