How Do Snakes Get into the Basement?

Snakes are long, cylindrical, and legless, which means they are not typically skilled climbers. When the pests invade homes, they must enter though openings found in the building’s foundation. This may include cracks in the bedrock, slits under doorways, pet flaps, tunnels that lead under structures, and warped siding. Once inside, snakes search for secluded locations with plenty of food and often end up in basements or crawlspaces.

What Makes Basements So Attractive?

When snakes enter homes intentionally, they are usually following prey or looking for suitable locations for hibernation. In the wild, the pests frequently rest in the spaces under rocks, and basements provide a similar environment. They offer consistent temperatures, moisture, darkness, relative quiet, and minimal activity, which makes them perfect for overwintering.

Property owners may also find snakes in the basement when rodent or insect infestations are present. Though different species of snakes prefer different food sources, rats, mice, and various types of insects are common prey. These pests are all commonly found in basements when they infest homes, thus making the basement attractive to hungry snakes.


Non-venomous snakes do not actually damage the structural integrity of buildings or threaten the lives of house residents. However, since venomous snakes are deadly and people are typically unable to distinguish between species of venomous and non-venomous snakes without getting close enough to be bitten, property owners are encouraged to contact a wildlife removal expert when they come across a snake in the basement. Wildlife control professionals have the ability to identify and remove snakes safely and efficiently.
