Kingsnake Care

What is a Kingsnake?

A Kingsnake is a beginner-friendly snake from Southwestern United States and Baja California. Adults reach 2.5–4 ft and can live 20+ years in captivity — a long-term commitment. California kingsnakes are hardy, active colubrids with voracious appetites and immunity to rattlesnake venom, making them excellent beginner snakes — but their snake-eating habit means they must always be housed alone.

What size enclosure does a Kingsnake need?

The minimum enclosure for an adult Kingsnake is 4×2×2 ft. Bigger is always better — Kingsnakes benefit from extra space to thermoregulate and express natural behaviours.

What you need:

1. Secure enclosure with tight lid — snakes are escape artists; latches or locks required.
2. Thermostat-controlled heat source — under-tank mat, radiant heat panel, or ceramic heat emitter.
3. Two hides minimum — one on the warm side, one on the cool side (security reduces stress).
4. Water bowl — large enough to soak in; changed frequently.
5. Appropriate substrate — aspen, coconut fiber, or bioactive blend; adequate depth to burrow.

What temperature does a Kingsnake need?

Kingsnakes need a thermal gradient: warm side 90–95°F, cool side 72–80°F. Use an under-tank heat mat, ceramic heat emitter, or radiant heat panel — all on a thermostat. Measure with a digital thermometer, not the stick-on strip gauges. Temperatures can drop to 68–75°F at night.

Do Kingsnakes need UVB?

Kingsnakes need low UVB — target UVI 1–2. A T5 HO 5–6% tube (e.g., Arcadia ShadeDweller) is recommended over supplementation alone. Use the UVB Calculator above to find the correct bulb and mounting height. Replace bulbs every 12 months regardless of whether they still emit visible light.

What humidity does a Kingsnake need?

Maintain humidity at 40–60%. Moderate humidity suits most commonly available substrates. Maintain a moist hide in one corner to support proper shedding. A digital hygrometer is essential.

What do Kingsnakes eat?

Kingsnakes are carnivores that eat whole prey — primarily mice and rats. Appropriately-sized whole prey (mice, rats, chicks, quail); hatchlings every 5–7 days, adults every 10–14 days; ophiophagous in the wild — never cohouse with other snakes Always offer prey frozen-thawed. Feed juveniles more frequently than adults; established adults can go weeks between meals without issue.

1. Whole prey — appropriately sized mice, rats, or other whole prey items.
2. Frozen-thawed preferred — never feed live prey; live prey can injure your Kingsnake.
3. Feeding frequency — juveniles every 5–7 days; adults every 1–4 weeks depending on size.
4. No supplementation needed — whole prey provides complete nutrition; no dusting required.

Can you house Kingsnakes together?

solitary — house individually; will eat other snakes including conspecifics Start with brief, calm handling sessions (5–10 minutes) and gradually increase as your Kingsnake becomes accustomed to you. Wash hands before and after every handling session.

Are Kingsnakes good for beginners?

Yes — Kingsnakes are an excellent first reptile. Animals cost 60–100 (standard banded), morphs 100–200+ depending on morph/locality. The main ongoing costs are frozen prey items, UVB bulb replacements (if used), and occasional vet visits.
