How Long Do Corn Snakes Live?

Corn snakes, scientifically known as Pantherophis guttatus, are a species commonly kept as pets. Though captively-bred corn snakes live a shorter lifespan, their wild counterparts can live up to 10-15 years or more. They typically reach full adult size within just one or two years after birth.

Factors That Impact Corn Snake Lifespan

To get the most out of your pet snake, it’s important to understand the conditions which affect your corn snake’s lifespan. Surrounding environment, nutrition, and genetics are all key factors that can play a role in their longevity.


Living in captivity means the environment can be 100% in control of their owner. All factors of their habitat should be taken into account, such as:

  • Temperature: Provides ideal environment for corn snakes
  • Humidity: A humidity level of 40-60% is best for corn snakes
  • Space: They prefer small, enclosed spaces, and should never be kept in fish tanks or other containers with limited airflow
  • Lighting: Provide essential UVA and UVB lighting throughout the day


Adequate nutrition is crucial for any pet, including corn snakes. Their diet should be high in protein, as they are most attracted to meals that resemble their natural prey. Feeding corn snakes live prey, such as small mice, crickets, or earthworms, is the best way to meet their dietary needs. Vitamins and minerals can be supplemented to ensure the best nutrients.


Some snakes naturally have a longer lifespan than others. This is mainly determined by their genetics, but it can also depend on their breeding. Responsible breeding practices are necessary when looking for a corn snake with the highest potential for a longer lifespan.

In Conclusion

Given that corn snakes are known for being hardy companions, providing them with the best care possible can lead to a longer life. The expected lifespan of a wild corn snake can range from 10-15 years or more, but those in captivity have shorter lifespans due to various factors. By providing proper nutrition, a suitable habitat, and a genetics, there’s a chance for their lifespan to reach the expected 15 years—or longer.
