Winnipeg Squirrels Face Lethal Bait & Foam
8 Apr
Summary
- Winnipeg is using Rozol RTU and RoCon for ground squirrel control.
- The methods involve lethal bait causing internal bleeding and suffocation.
- Animal advocates are appealing the provincial permit for these methods.

Winnipeg has initiated a pest management program involving deadly bait and suffocating foam to control its ground squirrel population, beginning Tuesday. The methods, utilizing Rozol RTU and RoCon, were approved by the province in March for use at athletic fields in nine city parks.
Animal welfare organizations, including the Winnipeg Humane Society and Animal Justice, have voiced strong opposition. They argue the products cause needless suffering and are not effective pest control. Animal Justice is appealing the provincial permit, urging the environment minister to suspend it due to procedural concerns.
The City of Winnipeg acknowledges the safety hazards posed by ground squirrel holes, which have led to park closures. The current license is valid only for the 2026 season. An environmental advisory committee will explore future pest management options. Daily monitoring will occur to minimize harm to other wildlife, with dead squirrels removed promptly and signage posted.
