Alberta continues to maintain it's rat-free status since the establishment of Alberta's Rat Control Program in 1950.
Though Alberta continues to maintain a Rat Control Zone on the eastern border of the province, rats are known to hitch-hike, and may still enter our border on transport trucks or personal vehicles. The most common rat found in the Canadian prairies is the Norway Rat.
It is important to understand how to prevent, identify, and report rats to ensure we remain rat-free.
Prevention
- Remove food sources
Eliminate anything that may attract rats, including garbage, spilled grain or feed, empty food containers, and pet or livestock feed. Rats are opportunistic and will eat almost anything available.
- Eliminate shelter
Keep yards, farmyards, and storage areas clean and uncluttered. Rats will shelter under almost any object on the ground, such as tires, boards, pallets, or bales, until they find more permanent cover.
- Rat-proof buildings
Reduce access to barns, sheds, granaries, and other structures by sealing gaps around doors, windows, and utility openings. Elevating outbuildings and regularly rotating stored grain or forage bales can also discourage rat activity.
- Check vehicles after travel
Inspect vehicle undercarriages after returning from out-of-province travel to ensure rats haven’t been transported unintentionally.
- Manage bale stacks and waste sites
Rats commonly inhabit hay and straw stacks. When stacking bales, consider placing bait in the lower one or two layers. Municipal waste sites should continue to manage garbage through burial or burning and use fencing to limit rat access.
Identification
Most reported rat sightings turn out to be muskrats, pocket gophers, ground squirrels, bushy-tailed wood rats or mice. However, local or provincial field staff investigate all suspected infestations.
The Norway rat has many distinguishing characteristics and clues. However, some other rodents can be mistaken for rats. Find out how to identify rats, and animals mistaken for rats.

Rat on Rats! Program
To raise awareness, the Alberta Invasive Species Council (AISC) worked with Alberta Agriculture and Irrigation's Rat Control Program to develop the new ‘Rat on Rats!’ campaign, which encourages the public to report observations of rats in the province.
