Do Snakes Hibernate?

Snakes do not hibernate. Snakes enter a state called burmation. 

Snakes are a member of the reptile family. Over 3,000 species of snakes live all around the world except Antarctica, Iceland, New Zealand, Ireland, and Greenland—all islands. All snakes have scales, which not only help them reduce friction to move more easily but hold in moisture for them in arid climates. And, like their reptile relatives, snakes are ectothermic creatures. This means they are cold-blooded and must rely on their environment to regulate their body temperature.

Snakes During the Winter

It is believed that snakes originated in the warm and forested environments of the southern hemisphere about 128 million years ago. Because they are expert travelers, able to traverse up to about 68,000 square miles, they have been able to spread far beyond their original territory. This ability also led them to inhabit regions with colder climates than their warm origins. Over the millennia, snakes have adapted incredibly well to ensure their viability in these colder climates including their ability to brumate.

Brumation is roughly equivalent to hibernation among mammals. When a snake goes into brumation, it becomes lethargic in an environment that is sufficiently insulated enough for survival in colder temperatures. Within nature, this environment can be a burrow, rock crevices, caves, and even beneath a pile of leaves. As a general rule, snakes begin and end brumation at 60 degrees Fahrenheit.

In the northern parts of the United States, as the weather cools to 60 degrees, the snake seeks out a place to brumate. In these colder climates, this could be around September or October. It then comes out of brumation when the weather once again is above 60 degrees in about May. This brumation period can be much shorter in more moderate climates of the nation. And, in warm climates such as the south or southwest, snakes have no need to brumate at all.

The main difference between hibernation and brumation is that when a mammal nears its time to hibernate, it eats more to gain enough fat to sustain it through its winter’s sleep. Snakes nearing brumation eat less because they do not want food in their system during brumation. During a snake’s brumation period, they are lethargic but not totally asleep. They will rouse to find the water they need to survive and will sometimes even be found sitting on a warm rock in the sun on a warmish day in January!

When a Snake Comes into Your House

In residential areas, snakes will use our homes, sheds, barns, and other manmade structures to help them regulate their body temperature. In hotter regions of the country, they are looking to cool off, while in colder regions, they are looking for warmth. Snakes do not cause any damage to a structure, and they cannot create an opening in your home like a raccoon or squirrel can.

Unfortunately, regardless of climate, no one wants a snake in the house, even though they are pretty fascinating creatures. Snakes will most likely choose a crawlspace, shed, or underneath a porch to take up residence. If a snake is in your home, it is for one of two reasons:

  • It made a wrong turn and found its way into your home through a gap in the foundation door.
  • You have a rodent problem, and it smells food.

Should you suspect a snake in your home or other structure, do not try to find it or get rid of it yourself. Because snakes are relatively shy of people, you might never actually see the snake but might find its shed skin. If you do see the snake, leave it alone. A snake rarely attacks unless provoked. But, you do not want to scare it into finding a hiding spot where you lose track of its whereabouts.

Call Critter Control to safely remove the snake and to repair areas where it entered so it or another creature cannot return. Critter Control uses only humane methods to remove snakes as they fulfill an essential function in our ecosystem. In addition, we can evaluate whether or not the cause of your snake infestation is due to brumation or a rodent infestation. If we find rodents, we can eliminate and repair any damage they may have caused.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
