Meet the animal
Heterodon nasicus is distinct from eastern and southern hognose snakes. Its upturned snout helps with burrowing, and females usually grow much larger than males. Flattening and death-feigning are defensive responses; do not provoke them for photographs.
Before you choose one
Confirm sex, stage and established frozen-thawed feeding before buying. Rear-fanged bites can cause significant local reactions, especially with prolonged chewing. Never hand-feed. Seek medical advice for substantial swelling or other concerning symptoms, and make sure holiday keepers understand this risk.
Set up its home
The adult layout proposed here is 120 × 60 × 60 cm. This allows more space than the cited UK starting size of 90 × 60 × 60 cm. Provide substantial safe digging depth, cover, warm and cool hides and a humid refuge. Scale the layout to actual size and secure gaps hidden beneath substrate.
Temperature and safe heating
Provide sheltered warmer and cooler areas with thermostat-controlled heat. Guides describe a hot area around 30–32°C and a basking surface around 32–35°C; those readings measure different things. Have one complete air, surface and night plan checked before use. Cooler air around 22–26°C is a starting proposal, rather than a reason to heat the whole enclosure evenly.
Daylight, shade and UV
Provide about 12 hours of daytime light and no night light. The UK guide proposes UVI 2–3, subject to individual review, particularly for reduced-pigment forms. Measure exposure at reachable positions and preserve deep shade; bulb percentage is not measured UV Index.
Water, moisture and airflow
The UK guide gives 30–50% enclosure humidity, with mostly relatively dry substrate, fresh water and a humid refuge. Avoid saturating the digging layer or using fine dusty sand alone. Check the selected hiding place as well as the air gauge.
Food and nutrition
Offer suitable frozen-thawed whole prey. UK starting intervals are about 5–7 days for hatchlings, 7–10 for juveniles and 14–21 for adults, adjusted to condition. Repeated daily offers are not a refusal plan. Check conditions and weight and seek a vet for prolonged refusal or illness.
Behaviour and handling
Use feeding tools and washed hands to separate food cues from handling. Let a settled snake move on supported hands near a safe surface. Do not force defensive displays, test bite reactions or attempt to make a frightened snake tolerate prolonged restraint.
Health and life stages
Record meals, weight and sheds. Sudden weight loss, respiratory signs, swelling, repeated regurgitation or abnormal stools need a reptile vet. Avoid force-feeding and improvised scenting chemicals without an individual plan. Do not impose seasonal cooling on a young, thin or unwell snake.
Buying and keeping records
Choose documented captive-bred H. nasicus and ask about morph-associated health and feeding reliability. Other Heterodon profiles do not automatically apply. Confirm current requirements separately for a cross-border transaction.
Your care routine
Prepare digging space, secure vents and reviewed heat and UV before arrival. Each day, check water, controls and condition. Locate the snake carefully during substrate work. Keep feeding and refusal instructions available for anyone providing cover.

Equipment checklist
Equipment examples for Western hognose snake, grouped by care need. Read the checks before choosing. Shop links are Amazon affiliate links. Items without a verified Amazon match have no shop link.
Plan the whole setup: These examples cover only part of the setup. Meet every care need and test the finished enclosure before arrival. Suitable equipment you already own may meet the need; optional tools are labelled.
Check each item for your animal’s size and life stage, safe access, compatible controls and measured conditions. The list does not certify an installation.

Alternative equipment
Repti-Life 72 × 24 × 24 inch vivarium — black
Amazon-selected 72 × 24 × 24 inch black flat-pack; 18 mm MFC, 4 mm toughened glass, six vents. External/nominal sizing, not certified usable space.
Secure doors, cables and vents; check the smallest life stage and actual usable space. External dimensions are not usable internal space. Check actual individual size, access, secure gaps, load support, furnishing clearance and any substrate depth before choosing this example.
This is an 18 mm melamine-faced chipboard enclosure with glass doors. Check the delivered internal length, depth and height against the care requirement after substrate, guards and furnishings; the inch label is external/nominal and is not proof of usable dimensions. Fit a suitable lock, protect board edges and keep water in watertight containers. Do not use unprotected board for a wet substrate build. Choose larger housing if any usable dimension or full-body extension fails.
Also plan for: Add the substrate, hides, cover and secure supports described in the care guide. The enclosure alone does not provide them.
Temperature and safe heating

Exo Terra Digital Thermometer
Model: PT2472
Records minimum and maximum air temperatures near a shelter your animal uses, to help you check the temperature plan.
Fit check: The remote probe measures air at one location. Keep it away from direct lamp heat, secure it safely and keep the display outside. Use separate probes for warm and cool areas where needed. Minimum/maximum readings help track changes; this device does not measure surfaces or control heating. Use a water-rated thermometer for submerged readings.
HabiStat Digital Dimming Thermostat Day/Night + Timer
Model: HTDD
Only for a compatible heater when extra heat is needed
Controls a compatible heater and allows separate day/night settings.
Fit check: HTDD controls compatible heaters up to 600 W, with no minimum load and a 0–50°C setting range. Socket I regulates the heater; socket II switches a separately verified load on a timer without temperature control. Never connect UVB to the dimming heater socket; the 600 W rating does not confirm T5 ballast compatibility. Guard the heater, secure the probe as instructed without tape and keep electrics dry. Check warm and cool areas with independent thermometers. The controller cannot cool a hot enclosure.
Zoo Med ReptiTemp Digital Infrared Thermometer
Model: RT-1
Checks basking and other occupied surface temperatures separately from air readings.
Fit check: Use this for surface temperatures, with air probes for air readings. Follow the distance and spot-size instructions, and account for reflective surfaces. It cannot measure internal body temperature.
Lighting, shade and UV
Read the care guidance for this need
Existing lighting may already provide a suitable day-night cycle. If you need extra lighting, use a switch or timer confirmed as compatible with its exact load, including any UVB ballast.
Arcadia ProT5 Forest 6% UV-B Kit 24 W
Model: RARTP24F
A UVB fitting to assess against the individual exposure plan, with complete shade available.
Fit check: RARTP24F is a 24 W, 570 mm UK 220–240 V fitting. Keep it away from water and spray; IP20 is not waterproof. Follow the manufacturer’s minimum animal clearance of 250 mm. This is a safety limit, not a recommended mounting height or UVI target. Check the complete fitting length, guards and reachable animal positions. Measure UV Index through the installed screen at each reachable height, with full shade available. Use a separately verified lighting circuit, never a heater’s dimming outlet.
Solarmeter Model 6.5R UV Index Meter
Model: 6.5R
Use your own meter or arrange an exposure check
Measures UV Index at the animal’s reachable back height, with the screen and guards fitted.
Fit check: Use a 6.5 or 6.5R UV Index meter, rather than a UVB irradiance meter. Measure all reachable positions and shaded retreats through the fitted screen and guards. You can borrow a suitable meter or arrange a competent exposure check instead of buying one. Confirm UK supply if buying.
Water, humidity and ventilation
Read the care guidance for this need
Exo Terra Digital Hygrometer
Model: PT2477
Tracks the air humidity cycle near an occupied area.
Fit check: Place the remote humidity sensor inside the enclosure, away from direct heat. The reading describes air at that point, so record its position and check other areas where needed. Inspect the substrate and damp retreats directly, and keep ventilation clear. A humidity reading cannot show whether an animal has drinking water.
Also plan for: Provide the drinking water, damp retreats or safe water area described in the care guide. A sprayer and humidity gauge cannot provide these on their own.
