Norway rats live in fields, farm lands, structures and woodpiles in the Calgary area. Because much of Alberta is agricultural farmland, and has a harsh climate the rats need to live as close to humans as they possibly can. Structures and food sources are sought out to survive. Rats are excellent climbers and often enter a building in the fall when outside food sources become scarce. They can gain entry to a home through a hole the size of a quarter. Because they are opportunistic scavengers, the Norway Rat is host to a number of pathogens and diseases. If that weren’t enough, rats are known to be fond of chewing through wiring, a definite fire hazard.
