As temperatures start to cool with the changing seasons, southern Albertans are being reminded that prairie rattlesnakes are still on the move.
According to the City of Lethbridge, prairie rattlesnakes begin their seasonal migration back toward their winter den sites in August. They typically remain close to their dens in September and may periodically enter them during cold weather in October.
Prairie rattlesnakes are commonly found throughout southern Alberta, including along dry coulee slopes and areas of cottonwood and river-bottom habitat. Their movements can occasionally bring them into neighbourhoods located close to coulees.
If residents come across a rattlesnake, they should stay calm and avoid approaching it. After noting where the snake is, they should slowly move away and leave plenty of space between themselves and the animal.
Rattlesnakes generally avoid people and will typically retreat rather than strike, according to the City of Lethbridge.
Pet owners should also take precautions. Dogs should be kept on a leash while walking in areas where rattlesnakes may be present.
For more information, residents can consult local guidance on avoiding rattlesnake encounters and what to do if they encounter one.
Anyone who needs a rattlesnake removed from an urban or recreational area in Lethbridge between April and December can call the Rattlesnake Call Line at 403-332-6806.
The snakes will eventually retreat to their winter dens, but until then, residents are encouraged to remain alert and give them plenty of room.
