Species Overview
Common name: Corn Snake
Scientific name: Pantherophis guttatus
Origin: Southeastern USA — woodlands, grasslands and farmland edges
Lifespan: 15–20 years (some over 25 with excellent care)
Adult size: 90–150 cm (3–5 ft)
Temperament: Docile, calm, easy to handle
Activity: Primarily crepuscular/nocturnal; occasionally active by day
Housing and Enclosure Setup
Enclosure Size
Hatchlings: Ideally, a cluttered 2ft vivarium; however, as babies are agoraphobic, sometimes a RUB suits them better.
Juveniles: 3ft vivarium.
Adults: Ideally, a 4x2x2ft vivarium.
Larger enclosures are recommended for enrichment and natural behaviour.
Must be secure and escape-proof, as corn snakes are strong and curious.
Substrate
Aspen, lignocel or a soil/sand mix for burrowing behaviour.
Provide a few centimetres of depth for digging and thermoregulation.
Avoid pine or cedar shavings (toxic oils).
Furnishings & Enrichment
Provide at least two hides — one at each end of the thermal gradient.
Include branches, cork bark, and foliage for cover and climbing.
Ensure you have a water bowl large enough for bathing.
Provide enrichment by changing the enclosure layout periodically.
Temperature, Lighting & Humidity
Temperature Gradient
Warm end 30–32°C Controlled by thermostat
Cool end 22–25°C
Night 20–22°C
Always use a thermostat (whether using a heat mat or ceramic bulb).
Monitor with digital thermometers at both ends.
Lighting
Corn snakes benefit from a low-level UVB (2.4–7%) for a natural circadian rhythm.
Maintain a 12 h light / 12 h dark cycle.
Humidity
Keep humidity between 40–60 %.
Provide a slightly moist hide during shedding periods.
Avoid excessive dampness — this can cause scale rot.
Diet & Feeding
Diet
Feed appropriately sized thawed frozen rodents (either mice or rats, depending on size and BCI of your corn).
Prey should be approximately the size of the snake’s mid-body width.
They will do best on primarily mice, although a mix of mice, rats and chicks would be great to promote natural behaviours.
Feeding Frequency
Hatchlings: Every 5–6 days
Juveniles: Every 7 days
Adults: Every 10–14 days
Always defrost prey fully before feeding.
Feed using tongs to avoid accidental bites.
Water & Hydration
Provide fresh water daily.
Replace immediately if soiled.
A suitably sized bowl should allow for soaking, especially before shedding.
Handling & Behaviour
Calm, regular handling helps maintain a docile temperament.
Handle for short sessions (10–15 minutes), several times weekly.
Always support the full body and avoid sudden movements.
Avoid handling for 48 hours after feeding to prevent regurgitation.
Snakes in shed should not be handled unnecessarily.
Cleaning & Hygiene
Daily: Spot clean faeces/urates and refresh water.
Weekly: Wipe down glass and decor with F10 disinfectant.
Monthly: Replace substrate and deep clean enclosure.
Health & Welfare Monitoring
Common Health Issues
Respiratory infection: Wheezing, mouth open and mucus. Review the temperatures and book them a vet check.
Mites: Tiny black dots and signs of irritation, such as soaking. Quarantine them, clean all decor, change substrate to a clean paper towel and remove and pourus decor.
Retained shed: Dull patches or visible eye caps. Give them a humid hide or warm bath.
Scale rot: Discoloured belly scales. Monitor them, apply a topical providone iodine and if you don’t see improvement, seek vet care. This is caused by incorrect substrate and increased moisture.
