Corn Snake Facts

Average Adult Size 4 to 6 feet long
Average Life Span up to 20 years with proper care
Diet carnivore

Will reach adult size in 2 to 3 years, under ideal conditions; upgrade habitat size as your snake grows.

Diet

A well-balanced corn snake diet consists of:

  • Appropriately sized frozen rodents, thawed/warmed to above room temperature.
  • Do not use a microwave to defrost frozen rodents and do not prepare them in the same area that you prepare food. If it is unavoidable, be sure to thoroughly disinfect the area. See the Feeding Frozen/Thawed Foods Care Sheet for more information.
  • If feeding your snake live rodents, do not leave them unattended. Live rodents can injure the snake, sometimes fatally.

Feeding

Things to remember when feeding your corn snake:

  • Feed juveniles once a week, adults every one to two weeks.
  • Feed in a separate tank so that your snake doesn't associate your hand or the habitat being opened with feeding.

Housing

  • Size – Appropriately sized and shaped habitat for an baby colubrid to accommodate normal behavior and exercise. At least a 20L to 40B is recommended.
  • Substrate – Aspen shavings, mulch-type such as coconut fiber bedding or reptile bark; dampened sphagnum moss.
  • Habitat – Provide a hiding area just large enough for your snake to fit inside and a branch or décor to climb on. Maintain 40 to 60% humidity; higher during shedding.
  • Temperature – Temperature gradient (85°F for the warm end; recommend radiant heat.
  • Lighting – Provide 8 to 12 hours of light daily. Don't leave white light on at all times; a nocturnal or infrared light should be used at night.
  • Adult corn snakes can be housed together but do not house different snake species together.

Normal Behavior

  • As your snake gets ready to shed, their eyes will turn a milky blue/grey over the course of a few days and their body color will start to dull and develop a whitish sheen. May become irritable; avoid handling if possible.
  • Appetite may vary.

Habitat Maintenance

  • Thoroughly clean and disinfect the habitat at least once a week: place snake in a secure habitat; scrub the tank and furnishings with a 3% bleach solution; rinse thoroughly with water, removing all traces of bleach smell; dry the tank and furnishings completely and add clean substrate.

Grooming & Hygiene

  • Snakes will regularly shed their skin; ensure humidity of habitat is at appropriate level to allow snake to shed properly.
  • Never try to remove eye caps by yourself. Seek veterinary care.
