Sarnia has approved another round of aerial spraying to control gypsy moths this year.
The $60,000 program will target the invasive moth caterpillars at Lakeview Cemetery, Sarnia Golf and Curling Club, Newell Street, Canatara Park and Marcin Park.
Sarnia spent $80,000 last years dousing infestations in Canatara Park and Lake Chipican Drive, Oak Acres Park, and parts of Lakeshore Road and Colborne Road.
There is visible improvement in the areas sprayed last year, city staff said.
An assessment based on egg casings indicates the most severe defoliation this year would be at the golf club and Lakeview Cemetery.
Trees near Newell Street, Marcin Park, Oak Acres and Canatara Park face moderate to severe defoliation.
The biological insecticide used is a bacterium found naturally in soil that’s been used for 30 years as a pest control agent on woods and agricultural crops.
