Aerial spraying for the tree-damaging LDD moth continues in various neighborhoods in Toronto tomorrow.
Weather permitting, on Friday, June 3, from 5 a.m. to 8:30 p.m., the biological pesticide will be distributed to sections 4 (Parkdale-High Park), 6 (York Center), 15 (Don Valley West), 16 (Don Valley East), 17 (Don Valley North), 18 (Willowdale) and 21 (Scarborough Center).
Drivers should keep in mind that High Park will be banned from vehicles during this time.
All insecticides used are non-toxic to humans, birds, mammals, adult moths, butterflies, bees and other insects.
Anyone who is worried about the negative impact should avoid the area during and after spraying.
Residents can visit Toronto’s LDD interactive moth treatment map to see if their neighborhood is in a spray zone.
The city of Toronto sprayed part of the roof of trees for the first time last weekend.
Aerial spraying is one of the most effective ways to control the outbreak of this non-native moth, which feeds on tree leaves and can cause extensive defoliation of the tree crown. The last time the city used this method was in 2020.
Other ways to control LDD moths include injecting trees, removing egg mass and spraying the ground.
In recent years, populations of LDD moths have increased in Toronto.
According to the Department of Northern Development, Mines, Natural Resources and Forestry of Ontario, this is the worst contamination in Ontario in 30 years.
Last summer, a significant portion of the tree canopy in Toronto was destroyed by LDD moths. To manage the situation this year, the city will spray about 80,000 acres of private and public land in the coming weeks.
Anyone with additional questions or concerns should contact 311.
