📋 Quick reference

🏠 Enclosure

Provide at least 120 × 60 × 60 cm for one adult and allow the snake to stretch fully. Check door gaps, vents and cable holes against the smallest animal housed. Fix rocks directly to the enclosure base so excavation cannot undermine them; retain clear sightlines to shift doors. Avoid sharp gravel, aromatic wood and unstable piles. Remove waste after securing the snake.

🪨 Substrate and furnishings

• Use at least the practical 120 × 60 × 60 cm layout in the table and allow the snake to stretch fully. Check door gaps, vents and cable holes against the smallest animal housed. Fix rocks directly to the enclosure base so excavation cannot undermine them; retain clear sightlines to shift doors. Avoid sharp gravel, aromatic wood and unstable piles. Remove waste after securing the snake.

• Provide about 5-8 cm of compactable soil mixed with washed sand, leaf litter and fixed low bark or stone retreats. Offer cover in both warm and cool areas without hiding the shift-door opening. Avoid a desert-sand display simply because some populations live in Texas. Paper keeps quarantine records easier to interpret.

💡 Lighting

• Provide about 12-14 hours of visible light during the active season, with darkness at night and shaded retreats. A species-specific UVB requirement has not been demonstrated. If low-level UVB is used, measure exposure and retain complete shade; do not infer lamp strength from habitat photographs. Guard lamps and wiring against contact.

🌡️ Heating and temperature

• Basking spot: 29-31 °C
• Warm zone: 23-27 °C
• Cool zone: 20-23 °C
• Night: 18-22 °C

💧 Humidity and water

• Air humidity: 45–65%.

• Use 45-65% relative humidity as an initial management band, with ventilation and a mostly dry resting surface. Provide a small locally moist retreat during shedding without wetting the whole enclosure. Offer clean drinking water continuously in a stable, shallow bowl, serviced through the protected system. Dry habitat does not mean absence of water. Persistent condensation or repeated retained sheds needs review; never peel skin or force soaking.

🐁 Feeding

Copperhead diets include mammals, insects and other small animals, varying with age and locality. An established thawed-mouse feeder is the most manageable acquisition. Offer modest whole prey matched to body width; small juveniles often need meals every 7-10 days and an experienced breeder’s protocol. Do not assume insect observations justify an insect-only diet.

An initial adult feeding interval is 10-14 days; adjust portions and timing to weight trend and condition. Deliver food through the collection’s protected feeding system. Avoid live rodents and substrate-coated food; dehydration, low temperatures and oversized meals increase regurgitation and impaction concerns. Whole prey normally needs no routine calcium or vitamin dusting. Do not improvise supplementation or force-feeding.

⚖️ Legal status

No CITES or specific EU wildlife-trade annex listing was found. Texas nongame take, possession and sale rules and Mexican wildlife rules still need checking, including older contortrix names. A permit category for non-native snakes must not be mistaken for the entire law governing native copperheads.

The Bern Convention is not a relevant native-range protection framework for this American species; this does not remove national wildlife or dangerous-animal restrictions.

Legal review: 17 September 2026. National capture, possession, registration, breeding, sale and transport rules may be stricter. Verify permits before transfer and keep invoices, breeder identity, parentage and import records. Trade status does not itself authorize keeping a venomous snake.

☠️ Venom

Copperhead envenoming can cause substantial pain, swelling, impaired limb function and tissue injury; serious systemic or clotting effects remain possible. “Usually survivable” is not a first-aid assessment. FDA-labelled North American pit-viper antivenom is a hospital option, not a guarantee of local access or a reason to delay emergency care. Severity varies; a small wound does not rule out serious or delayed envenoming.

Treat every bite as an emergency, including an apparently dry bite. Move away, call emergency services, keep the person still, remove rings and support the limb without compression. Do not cut, suck, ice or tourniquet the wound, and do not catch the snake. Follow poison-centre instructions. Agree a receiving hospital and antivenom access before acquisition; treatment belongs in hospital.

🩺 Common problems

• Overheating: repeated escape attempts or unusual exposed resting require immediate measurement of the cool retreat.
• Dysecdysis and dehydration: review drinking access and the moist refuge; repeated problems need veterinary assessment.
• Respiratory infection or stomatitis: wheezing, bubbles or oral discharge require prompt professional care.
• Dermatitis, impaction, obesity and parasites: dirty wet bedding, substrate ingestion, excessive feeding or persistent weight loss need correction and diagnosis. Do not use automatic deworming or home restraint.
