Western Hognose Snake Care
Heterodon nasicus
Western hognose snakes are a fossorial (burrowing) species native to western North America and the most common hognose available in the pet trade, though Mexican, Eastern, and Southern hognoses are occasionally available as well. Females grow larger than males, with adults reaching up to 35″ in length.
Western hognoses are considered venomous — they are rear-fanged and their venom is typically not life-threatening to humans, but bites can be painful and individual reactions may vary. Care should be taken during handling and feeding. Thin leather gloves are an option when handling. This species is solitary and should never be housed together.
Life expectancy: 10–15 years in captivity.
Behavior
When threatened, hognose snakes may puff up, hiss, flatten the skin behind the head, emit foul-smelling musk, or play dead by rolling onto their back, spasming, and opening their mouth. Biting when threatened is rare but possible.
Enclosure
Floor space is more important than vertical height for this species. A minimum 40-gallon enclosure is recommended. Front-opening enclosures are ideal, as they allow you to approach and handle the snake from the side rather than from above.
Substrate
Choose a substrate that supports burrowing, at least 4 inches deep. Good options include:
- Aspen shavings
- Zoo Med Reptisoil
- Zilla Jungle Mix
Spot clean as needed and replace fully every 3 months.
Decor & Enrichment
Provide several hides and caves, cork bark flats, and branches to give the snake places to shelter and explore.
Humidity
Maintain 30–50% humidity, measured with a digital hygrometer.
Heating
Provide a consistent temperature gradient throughout the enclosure:
- Cool end: 70°F
- Warm end: 90°F
- Basking area: 95°F
Monitor with digital probe thermometers at both ends and spot-check with an infrared thermometer gun. Basking bulbs or ceramic heat emitters are recommended.
UVB Lighting
Western hognoses are diurnal (active during the day) and benefit from UVB lighting on a timer for 10–12 hours per day. Zoo Med Reptisun T8 5.0 bulbs or similar are a good choice. Place the bulb approximately 12 inches from the basking area, adjusting based on bulb type and whether a mesh screen top is present. Replace bulbs every 6–12 months per manufacturer guidelines.
Diet & Feeding
Hognose snakes are carnivores requiring whole prey. In the wild they eat toads; in captivity, suitable food items include:
- Feeder rodents (frozen/thawed or fresh killed only)
- Quail eggs
- Repti-links micro and mini sausages (made from whole frogs or quail)
Picky snakes can be encouraged to eat rodents by scenting prey with frog or lizard scent juices. Always feed with tongs and off substrate to prevent accidental bites and reduce the risk of ingestion and impaction.
- Juveniles: every 3–4 days
- Adults: once weekly, or when actively exhibiting hunting behavior
Prey items should be no larger than the width of the snake’s head. Captive snakes are prone to obesity — feeding on demand rather than on a strict schedule helps prevent this. Do not handle for at least 2 days after feeding to reduce the risk of regurgitation.
Weigh your snake at least monthly and keep a journal to track growth. Unexpected weight loss warrants an examination by a veterinarian familiar with snakes.
Water
Provide a clean bowl of fresh water large enough for the snake to soak in, changed daily.
Veterinary Care
An annual wellness examination and fecal screening for parasites is recommended for all reptiles.
