Eastern Copperhead — Care Sheet & Morphs

Husbandry requirements

Eastern Copperhead — origin: Eastern and central United States (North America); deciduous forests, woodland edges, rocky talus slopes and wooded wetlands..

Terrarium temperature gradient

Night min18 °C

Cool side20–24 °C

Warm side27–30 °C

Basking spot30–32 °C

A temperate species: maintain a clear thermal gradient. A moderate warm spot under the lamp, never scorching. A night-time drop is beneficial in summer. For breeding, a winter brumation lasting several months at low temperatures with a shortened photoperiod is required.

Enclosure (adult)

120 × 60 × 45 cm

Sturdy terrestrial terrarium with a LOCKABLE, escape-proof closure (venomous species — safety standards essential: latches, a 'venomous' warning label, controlled access).

Floor length at least equal to the snake's length; the species is terrestrial and barely climbs. Provide sealed hides on both the warm and cool sides, plus a humid hide. In France/the EU, keeping requires a certificate of competence and an establishment-opening permit; the species is NOT listed under CITES, but its venomous nature places its keeping under strict regulation.

Humidity

40–60 %

Moderate humidity. Provide a humid hide (sphagnum), especially during shedding; avoid a permanently waterlogged substrate, which promotes scale rot.

Substrate

Shredded aspenCoconut fibreCypress mulchUntreated leaf litterOrchid bark

A loose substrate that allows partial burrowing and suits moderate humidity; clean it regularly to prevent skin infections and parasites.

UVB

Optional

Low-level UVB is beneficial (a low-percentage tube, low Ferguson zone) although not strictly essential for a partly nocturnal species; it improves calcium metabolism and natural behaviour. Provide a shaded area.

Water source

Always available

Clean water available at all times in a stable bowl wide enough for soaking; refresh it frequently. Tend the water source with the same safety precautions (hook).

Origin

Viperidae (Crotalinae — vipère à fossettes)

Eastern and central United States (North America); deciduous forests, woodland edges, rocky talus slopes and wooded wetlands.

Feeding & health

Diet

Carnivore (insectivorous/vertebrate-eating depending on age) — In captivity: appropriately sized rodents (mice, young rats). In the wild: rodents, amphibians, lizards, birds and insects — cicadas make up a notable seasonal feast.

Feed thawed prey with tongs/hook, never bringing your hand close. Adults at spaced-out intervals; juveniles more often. Neonates attract their prey by 'caudal luring' (wiggling the yellow tail). Avoid overfeeding, as this species readily becomes overweight.

Breeding

Viviparous

Litter of live young. Mating occurs in spring and autumn; a winter brumation at low temperatures is generally required to trigger breeding. The neonates are fully venomous from birth.

Health watch points

Respiratory infections (inadequate heating or ventilation)
Stomatitis (mouth rot)
Dysecdysis / incomplete sheds from insufficient humidity
Dermatitis and scale rot (blister disease) on a too-damp or dirty substrate
Internal parasites, common in wild-caught individuals

Frequently asked questions

Answers to the most common questions about keeping the eastern copperhead.

Is the copperhead dangerous?▾

Yes, it is a venomous species (a pit viper) reserved for experienced keepers holding the appropriate legal permits. Its hemotoxic venom makes every bite painful and medically serious: rarely fatal in a healthy adult, but always requiring hospital care. Handling must be done only with a hook or tongs, never with bare hands.

Why does it cause accidental bites?▾

Unlike rattlesnakes, which give a warning, this cryptic snake relies entirely on its camouflage and freezes instead of fleeing: it gets stepped on or handled without being noticed, which triggers the bite. It nevertheless remains reluctant to bite as long as it is not touched.

Is it a species for beginners?▾

Absolutely not: it is classed as an expert-level species. Even though it is sometimes presented as a starter venomous snake, it remains dangerous, and in France keeping it requires a certificate of competence as well as an establishment-opening permit.

How big does it get?▾

Its average adult size is 60 to 90 cm, with a record exceeding 130 cm, and a stout build though less bulky than the water moccasin. Neonates measure about 20 to 25 cm and sport a bright yellow tail tip used to lure prey.

What terrarium and safety measures are needed?▾

A sturdy terrestrial terrarium with a lockable, escape-proof closure, at least 120 × 60 × 45 cm, fitted with latches, a 'venomous' warning label and controlled access. As a terrestrial species that barely climbs, it needs at least two sealed hides (a warm side and a cold side) and a humid hide.

What temperatures should it be offered?▾

Maintain a clear gradient: a cool side of 20 to 24 °C, a warm zone of 27 to 30 °C and a moderate basking spot of 30 to 32 °C, never scorching, with a beneficial night-time drop to around 18-20 °C in summer. This is a temperate species that needs these variations.

What does it eat?▾

In captivity it feeds on appropriately sized rodents (mice, young rats), given thawed with tongs or a hook, never bringing your hand close. Allow one prey item every 10 to 14 days for an adult, more often for juveniles, avoiding overfeeding since this species readily becomes overweight.

Does it need UVB?▾

Low-level UVB (a 5-6% T5 tube, UV index of about 1 to 3) benefits calcium metabolism and natural behaviour, without being strictly essential for a partly nocturnal species. Always provide a shaded area.

How does its activity change with the season?▾

It is diurnal in spring and autumn, then becomes nocturnal or crepuscular in summer, adjusting its rhythm to the ambient temperature. This behaviour should be respected when managing lighting and heating.

How does it reproduce?▾

It is viviparous and gives birth to 4 to 15 live young, already fully venomous from birth. Breeding generally requires a winter brumation of 2 to 3 months at 10-13 °C with a shortened photoperiod, with matings taking place in spring and autumn.

How long does it live?▾

Commonly 15 to 20 years, and up to 25 years or even more in captivity under good conditions.

What health problems should be monitored?▾

Watch for respiratory infections (inadequate heating or ventilation), stomatitis (mouth rot), incomplete sheds from insufficient humidity, dermatitis and scale rot on a substrate that is too damp or dirty, as well as internal parasites, which are common in wild-caught individuals.
