Early Poster for Rat Control (1955)
Today, provincial legislation requires all Albertans take measures to control rats.

In the fall, rats are on the move, seeking food and shelter before winter sets in. They take up residence in what ever is available and close to the ground, such as rubbish, lumber, warehouses, outbuildings, and machinery. As long as they are close to food and sheltered from the weather and predators, a pair of rats will thrive and produce as many as 15,000 more rats every year.

Large Incisor Teeth that Grow Continuously
Rats are very destructive. A rat's front teeth never stop growing, so to keep them short, they gnaw on almost anything including wooden beams, plastic siding, electrical wiring, insulation, and even concrete.

Rats can exist on an incredible diet that includes:
  • Grain/forage
  • Green vegetation
  • Bread
  • Fat, grease
  • Candy, sugar
  • Fish, meat
  • Pet food
  • Spoiled or rotten food
  • Dead animals
