Corn snakes are a nocturnal species that visit burrows of other species, and explore tree canopies looking for food and shelter. They prefer to remain hidden during the day, residing under bark, logs, rocks and other matter. Corn snakes will hibernate over winter.

Life cycle and breeding

Corn snakes become reproductively active as they reach two years of age. They can lay between 10-30 eggs, which normally hatch at about 65 days. They can live up to 25 years in captivity.


Corn snakes prefer open and dry habitats such as fields, woodlands, grasslands and rocky areas. They can tolerate a range of habitats including forests, agricultural farm land and semi-urban landscapes. They are a ground dwelling species, however, may also climb trees and can be found in farm sheds or abandoned buildings. Because of these habitat features, they are highly suited to Australian conditions. Outside of their natural geographic range, populations have established in the Cayman and Virgin Islands, and the Bahamas.

For these reasons, the following precautions should be followed:
• Contact a wildlife handler or local vet to assist with safely containing the animal.
• Wear disposable gloves when handling animals. 
• Wash hands well in warm soapy water after handling animals.
