Western Hognose Snake (Heterodon nasicus)

Western hognose snakes are charming, comical, and mildly venomous rear-fanged snakes native to the central plains of North America. Their venom is mild and primarily affects amphibians — bites in humans are rare and typically cause only local swelling, though some people may have allergic reactions.

⚠️ Note: Hognose snakes are rear-fanged and technically venomous. While bites are generally harmless, monitor for allergic reactions and consult a doctor if bitten.

Housing

A 20-gallon (75L) enclosure is sufficient for most adults. Hognose snakes love to burrow — provide at least 4–6 inches of loose substrate (aspen, coconut fibre). They are escape-prone, so secure your lid.

Temperature

• Warm side: 85–90°F (29–32°C)
• Cool side: 70–75°F (21–24°C)
• Humidity: 40–50%

Feeding

In the wild they eat toads and frogs, but captive hognose snakes can usually be transitioned to frozen/thawed mice (sometimes scented with toad or frog). Scenting with salmon oil or frog scent can help reluctant feeders.

Defence Behaviour

Hognose snakes are famous for their dramatic death feigning — they will roll onto their back, writhe, and play dead. They may also flatten their necks and hiss theatrically. This is all bluff; they rarely actually bite.
