Saskatchewan SPCA opposes use of strychnine for pest control

Apr 15, 2026 | 12:08 PM

The Saskatchewan SPCA is speaking out against an emergency registration for liquid strychnine to control a growing gopher population in Saskatchewan and Alberta.  

Education Coordinator Mikayla Basset said SPCA understands farmers do need to control these populations but there are repurcussions. 

“We sympathize with them, but we also need to be aware of the risks that putting poison in the environment can have especially as secondary poisoning is a big concern,” Basset said. “Secondary poisoning is when an animal eats a baited ground squirrel. A ground squirrel that has been poisoned dies and then gets eaten by a predator and that predator then gets poisoned and dies itself.” 

Basset said the spread through the food web is very concerning for the SPCA and can cause very damaging ecological issues.    

She added liquid strychnine leads to significant suffering for the gopher.    

“It’s a horrible death as it causes severe muscle spasms, seizures and respiratory failure and it can take hours to die. That’s significant suffering and not humane.”    

Basset believes there are other gopher control options available for farmers and ranchers to control gophers. 

“Things like habitat modifications, like promoting tall vegetation, as ground squirrels prefer open fields. Dense vegetation is a useful tool in slowing or preventing colony expansion,” she said “Predation plays a significant part in natural population control. Installing raptor platforms and nest boxes can be really great for increasing that natural predation. Also, preserving habitat for ground predators, such as retaining vegetation around water and fence lines and sloughs to support those habitats.” 

Basset said farmers can also use mechanical controls like disrupting burrows by plowing or cultivating, using traps or shooting the gophers if the producer has a license in an area that allows for it.  

“Poisons are maybe a little bit faster, but they cause a lot of harm to the environment, and those environmental risks are really unacceptable.”   

SPCA added gophers play a key role in the Prairie ecosystem, primarily being a key food source for a variety of natural predators.
