Consultation on Strychnine and Its Associated End-use Products (Ground Squirrel Use), Proposed Re evaluation Decision PRVD2018-13

Strychnine is a registered pesticide used by growers to control ground squirrels. Products containing strychnine for ground squirrel control include Maxim 2% Liquid Strychnine Concentrate and S.A.R.M Gopher Poison R.T.U.

Following a scheduled re-evaluation under the Re-evaluation Program, Health Canada’s Pest Management Regulatory Agency (PMRA) is consulting Canadians on the proposal to cancel the use of strychnine for ground squirrel control due to effects on non-target animals.

This review identified environmental concerns in the potential poisoning of non-target animals, including species at risk such as the swift fox and burrowing owl. There is concern mitigation measures would not be practical.

As such, Health Canada is proposing to cancel the registration of Maxim 2% Liquid Strychnine Concentrate, and to require removal of ground squirrel use from the label of S.A.R.M Gopher Poison R.T.U.
