The spongy moth is a non-native insect found throughout southern Ontario that feeds on a variety of tree species such as oak, birch and maple. They eat leaves, which can cause trees to lose some or all of their canopy, however, long-term effects can be reduced and prevented through management techniques.
Southern Ontario, including Richmond Hill has been experiencing a spongy moth outbreak since 2019. Outbreaks typically last 3 to 4 years.
Recent York Region survey results indicate that the impacts of spongy moth are expected to be minimal this year. As a result, the City will continue to monitor trees on public property, but no city-wide management activities are planned.
Residents are encouraged to continue monitoring the trees on their property for any signs of infestation and take action if necessary.
