The University of Lethbridge is built into the coulee slopes along the Oldman River, an area that’s also habitat for the prairie rattlesnake.
Rattlesnakes are periodically seen on campus during the spring, summer and fall months as they travel in search of food. The rattlesnakes will soon start migrating back to their den site for the winter but they may still make an appearance on campus as the fall semester gets rolling.
The prairie rattlesnake can be identified by its arrow-shaped head and its olive green, yellow and brown colouring.
Often the first indication of a rattlesnake is the sound of its rattle. Rattlesnakes are shy by nature and will retreat rather than strike if they have the choice. But if they are surprised, cornered or stepped on, they can strike at a distance of up to half their length. Their venom is not especially lethal and no one in Alberta has died from a prairie rattlesnake bite.
If you encounter a rattlesnake on campus, back away slowly, remain calm, and give the snake plenty of space. Call U of L Security Services at 403-329-2345 and they will stand by and make arrangements for the snake to be relocated.
In the event a rattlesnake bites you, remain calm and get to a hospital as soon as possible. Do not try to suck or cut the venom out as it is quickly absorbed into the blood stream. Early treatment of rattlesnake bites usually results in a full recovery.
In Alberta, it’s illegal to kill a rattlesnake, possess rattlesnakes or their parts, or damage their denning areas.
More information is available on the City of Lethbridge website and information pamphlets are available at U of L Security Services. A locally made video of a rattlesnake relocation can be found on YouTube at Rattlesnake at Piikani House.
