It's almost Spongy Moth time!

The good news is it shouldn't be so bad this year.

From early May to mid-July - Remove caterpillars using burlap traps.

Starting April 3, residents can pick up a free burlap kit at the Operations Centre (1200 Elgin Mills Rd. E) during regular business hours, Monday to Friday, 8:30 a.m. to 4:30 p.m. while quantities last.

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.

  • Educational resources and more information can be found on the City’s website at
