Update on Tent Caterpillars

The Town of Whitchurch-Stouffville, forwarded your concern to the Region, as Aurora Road is a Regional Road. Thank you for bring this issue to our attention. Forestry staff inspected the area today and confirmed that the insect is fall webworm (a species similar to forest tent caterpillar). This year has been particular bad for fall webworm. While the tents and damage to leaves is unsightly, it has minimal impact on tree health. Since this pest is not consider a threat to tree health we do not undertake an control of the insect.

We appreciate your diligence in reporting this issue and if you have any further questions please give me a call at 905-830-4444 ext. 75271.

Thank you again.
