Do Rattlesnakes Hibernate?

With lifespans lasting upwards of twenty years, rattlesnakes quickly learn how to survive in the cold. This can be difficult because their cold-blooded bodies keep them at the same temperature as their surroundings. Rattlesnakes do not hibernate during winter. However, they become much less active while in a state known as brumation.

Survival of the Fittest

During brumation, rattlesnakes lower their metabolic rates by nearly 70 percent, allowing them to live for months with little or no food. On warmer days, a rattlesnake in winter will bask in the open and soak up as much sun as possible. It will also hunt for small rodents that may serve as a much-needed meal.

Where Do Rattlesnakes Hibernate?

In warm weather, the pests hide near homes among rocks and thick brush. When temperatures drop, rattlesnakes avoid sub-zero conditions and find safe havens below the ground.

Rattlesnakes in the winter take refuge in animal dens and may curl up under a porch or shed to find warmth. The pests return to the same denning sites year after year, which can create conflicts with humans or other animals in the area.

Removal

A female rattlesnake reproduces every two or three years and has about 24 babies in each litter. Because of their birth rate and denning instincts, rattlesnakes around the home can become an urgent issue. Concerned property owners should contact Critter Control for expert rattlesnake removal.
