Do Snakes Hibernate in Houses? 10 Tips to Keep Snakes Out

As winter sets in and nature’s creatures prepare for the cold months ahead, one question that often arises is where snakes go during hibernation.

One might imagine the wilderness as the ideal habitat for hibernation, but occasionally, the line between nature and our homes blurs, leaving us wondering if some unexpected guests might be seeking warmth and shelter within our own living spaces. 

The notion of snakes seeking refuge in our homes during hibernation may spark curiosity and concern alike. So, do snakes hibernate in houses?

Snakes may hibernate in houses if conditions suit them. If you suspect a snake is inside your house, look for hiding spots, droppings, or shed skin. To prevent snakes from hibernating in your house, make sure to seal any cracks, remove debris, trim plants, and use snake repellents outdoors.

Do Snakes Hibernate?

In general, snakes do not hibernate in the same way that some mammals, such as bears or groundhogs, do. However, they do undergo a period of inactivity during colder months in regions with harsh winters or during dry seasons in arid areas. This inactivity is often referred to as “brumation.”

The primary difference between hibernation and brumation is that hibernating animals enter a state of deep sleep with a reduced metabolic rate, whereas snakes in brumation maintain a degree of responsiveness and can occasionally emerge to bask in the sun on milder days.

It’s essential to remember that not all snakes undergo brumation. Tropical and subtropical species usually remain active year-round since they experience milder environmental fluctuations.

When Do Snakes Start Hibernating?

The timing of when snakes start hibernating or enter brumation depends on the species and the climate in which they live. Generally, snakes begin their preparation for hibernation as the weather starts to cool down. 

In temperate regions with distinct seasons, this typically occurs in the late summer or early fall. In colder climates, snakes will enter their hibernacula (hibernation sites) sometime between October and November. 

During this period, their metabolic rate decreases significantly, and their activity level diminishes. They may still occasionally emerge from their hibernation sites on warmer days to bask in the sun, but for the most part, they remain in a state of torpor until spring arrives.

Why Do Snakes Hibernate?

Snakes hibernate as a survival strategy to cope with harsh environmental conditions, particularly in regions with cold winters or dry seasons. During hibernation, snakes enter a state of dormancy to conserve energy when resources are scarce and temperatures are unfavorable for their usual activities.

Where Do Snakes Normally Hibernate?

Snakes normally hibernate in locations that offer protection and insulation from harsh environmental conditions, especially during colder months or dry seasons. 

The specific hibernation sites can vary depending on the snake species and the geographical region, but some common locations include:

  1. Communal Dens: Some snake species, such as garter snakes and timber rattlesnakes, may hibernate in communal dens with other snakes. These dens are often found in rocky outcrops, underground burrows, or abandoned mammal burrows.
  2. Rocky Crevices: Snakes may seek out crevices and fissures in rocky areas, like cliffs or boulder piles, as hibernation sites. These natural openings provide insulation and protection from the elements.
  3. Burrows: Some snakes, like the eastern indigo snake, may hibernate in burrows they dig themselves or use abandoned burrows of other animals, such as rodents.
  4. Underground Holes: Snakes may choose to hibernate in holes or tunnels in the ground, which provide a stable and protected environment.
  5. Tree Hollows: Arboreal snake species may hibernate in tree hollows or other protected cavities in trees.
  6. Caves and Caverns: In certain regions, snakes might hibernate in caves and caverns where the temperature remains relatively stable throughout the winter.
  7. Man-made Structures: In urban or suburban areas, snakes might also seek shelter in man-made structures, such as basements, crawl spaces, or abandoned buildings, as hibernation sites.

It’s essential to respect snakes’ hibernation sites and not disturb them during this critical period of survival. If you encounter hibernating snakes on your property or in the wild, it’s best to leave them undisturbed and seek guidance from local wildlife experts or conservation authorities if needed.

Do Snakes Hibernate in Houses?

Snakes do not typically hibernate inside houses as their natural hibernation sites are outdoors in protected areas like communal dens, rocky crevices, burrows, or underground holes. However, there are rare instances where snakes might accidentally hibernate inside houses if the conditions suit them.

If a snake does enter a house, it will likely prefer areas that resemble its natural hibernation spots—places that offer darkness, insulation, and protection. 

Common areas inside a house where a snake might choose to hide or hibernate include:

  1. Basements: Snakes may seek out dark and undisturbed corners or gaps in basement walls or floors.
  2. Crawl Spaces: If a house has a crawl space, snakes might find it appealing for hibernation, especially if there are openings or cracks.
  3. Attics: Attics can provide suitable hiding spots for snakes due to their relative isolation and quietness.
  4. Closets: Snakes might seek shelter in closets, especially if they are cluttered or have gaps where a snake can hide.
  5. Wall Voids: Wall voids or gaps between walls can offer snakes an ideal hiding place with some insulation from temperature fluctuations.
  6. Chimneys: Snakes might accidentally fall into chimneys and end up inside the house.

It’s important to note that instances of snakes entering houses are rare and usually happen unintentionally. To deter snakes from finding their way inside your house, you need to regularly inspect the house for any potential entry points and promptly addressing them can help. 

How to Tell If A Snake Is Hibernating In Your House?

Determining if a snake is hibernating inside your house can be challenging since snakes are skilled at hiding and may choose secluded spots. However, here are some signs that might indicate a snake’s presence and potential hibernation:

  1. Shed Skin: Snakes shed their skin periodically, and finding shed skin in or around your house is a clear indication that a snake might be present.
  2. Droppings: Snake droppings, also known as feces or scat, may be found in areas where a snake is hiding or moving. Snake droppings are usually long and tubular with a whitish color.
  3. Tracks and Trails: In dusty or sandy areas, you might spot snake tracks or trails as they move around.
  4. Unusual Odors: Some snakes emit a musky or pungent odor, especially when they are in hibernation or stressed.
  5. Disappearing Food: If you have rodents or other small animals in your house, and suddenly their numbers decrease or they seem to vanish, it could be a sign that a snake is preying on them.

Remember that snakes are generally shy and prefer to avoid humans. If you suspect a snake is hibernating in your house or notice any of these signs, it’s essential to approach the situation with caution and avoid disturbing the snake

Trying to handle or remove the snake yourself can be dangerous, especially if you are unfamiliar with snake species and behaviors. So, it’s best to contact a local wildlife expert or a professional snake removal service to assess the situation and safely handle the situation without harming the snake or putting yourself at risk.

How to Prevent Snakes from Hibernating in Your House?

To prevent snakes from hibernating in your house, follow these steps:

  1. Seal Entry Points: Inspect your house for any gaps, cracks, or openings in the foundation, walls, doors, and windows. Seal these entry points to prevent snakes from getting inside.
  2. Keep the Surroundings Clean: Remove debris, piles of leaves, and other clutter near your house. Snakes are attracted to areas with hiding spots and shelter.
  3. Trim Vegetation: Keep grass and shrubs well-trimmed, especially around the house’s perimeter. Avoid tall vegetation that snakes could use as cover.
  4. Secure Garbage: Ensure that your garbage cans have tight-fitting lids. Rodents attracted to unsecured trash can lure snakes to your property.
  5. Check Crawl Spaces and Basements: Inspect crawl spaces and basements regularly for signs of snake activity. Seal any openings or cracks that might allow snakes to enter.
  6. Install Screens: Use mesh screens on vents, windows, and other openings to prevent snakes from getting inside.
  7. Use Snake Repellents: Consider using commercially available snake repellents around the perimeter of your house. These products emit odors that deter snakes from approaching.
  8. Educate Yourself: Learn about the snake species common in your area and their habits. Knowing their preferences will help you tailor prevention methods.
  9. Avoid Attracting Prey: Taking measures to control rodent populations around your property will reduce the likelihood of snakes being drawn to your house for food.
  10. Seek Professional Help: If you encounter a snake on your property or suspect a snake might be hibernating in your house, contact a local wildlife expert or a professional snake removal service. They can safely assess the situation and handle any snakes present without harming them.

By following these preventive measures, you can minimize the chances of snakes seeking shelter or hibernating in your house and create an environment that is less attractive to them.


In conclusion, understanding snakes’ hibernation behavior is essential for coexisting peacefully with these remarkable creatures. While snakes do not typically hibernate inside houses, they may accidentally find their way indoors if conditions are favorable. 

To minimize the risk of snakes hibernating in houses, homeowners should remain vigilant and take preventive measures. It is also crucial to seek professional assistance from wildlife experts or professional snake handlers is crucial to safely and responsibly handle the situation.
