History of rat control in Alberta

The province has had no breeding populations of rats for over 70 years thanks to its storied Rat Control Program.

They gradually spread westward over most of the continent as North America became settled, farms were built closer together, and cultivated land began to dominate the landscape. Conferences on rat control were held in 6 towns in eastern Alberta, and 2,000 posters and 1,500 pamphlets were distributed to grain elevator, railway station, school and post office staff, as well as private citizens. Recommended toxicants were red squill, antu, barium carbonate, zinc phosphide, 1080, thallium sulfate, arsenic, strychnine alkaloid and warfarin.
