Annual Cankerworm Spray Program Begins

The City began its annual cankerworm spray program today in areas with high insect counts and where trees are most at risk. 

“This program helps protect trees from cankerworms,” said Russell Eirich, Director of Parks & Open Space Services. “We’re targeting areas where cankerworm numbers are highest so we can reduce damage and keep our trees in good shape.” 

More than 4,000 trees are scheduled to be sprayed this year to help protect them from cankerworm damage. Crews will use BTK, an organic product approved by Health Canada, which effectively kills cankerworms but is harmless to pets, wildlife and humans. Cankerworms feed on young leaves, causing significant leaf loss that can weaken or kill trees over time. 

At least 48 hours in advance, residents in designated spraying areas will receive a hand-delivered notification that spraying will take place near their homes. The notice will include tips to help residents prepare, including:  

• Keeping family members and pets away from spray crews.
• Closing windows and doors.
• Moving cars off the street, if possible.

The cankerworm spray program protects Regina’s trees and ensures that residents can continue to enjoy a healthy urban forest for years to come.  

Residents can find more information, including a spray sitemap, at Regina.ca/Pests or by calling the City Pesticide Advisory Line at 306-777-7777.
