Aerial spray treatment spraying has been approved for Greater Victoria in an attempt to eradicate the invasive spongy moth and minimize the risk they pose to forests and farms.
Under the direction of the provincial Spongy Moth Technical Advisory Committee, 170 hectares in North Saanich, 120 hectares in the Gorge-Tillicum area, 31 hectares in Esquimalt and Victoria West and 430 hectares in Belmont will undergo the spray treatment.
