PUFF ADDER (Bitis arietans) CARE SHEET
The Puff Adder (Bitis arietans) is a large, heavy-bodied venomous viper with one of the widest distributions of any African snake. It occurs across much of sub-Saharan Africa and also extends into parts of North Africa and the Arabian Peninsula.
Unlike the Gaboon Viper, which is strongly associated with humid forest habitats, Puff Adders occupy an enormous range of environments including savannah, grassland, scrub, woodland, semi-arid country and agricultural margins.
This wide distribution means there is no single humidity figure or seasonal pattern that perfectly represents every population.
Puff Adders are primarily terrestrial ambush predators. They commonly remain motionless for long periods and rely heavily on camouflage, but they are capable of an extremely rapid defensive strike.
Their tendency to remain still or hiss before striking must never be interpreted as predictability or safety.
The species is capable of causing severe and potentially fatal envenomation and is suitable only for appropriately experienced specialist venomous-reptile keepers.
This care sheet provides comprehensive husbandry guidance. It is not a venomous-snake handling or restraint manual.
Captive-bred animals of documented provenance should be strongly preferred.

IMPORTANT VENOMOUS SPECIES WARNING
The Puff Adder is a dangerously venomous snake.
A bite constitutes a medical emergency.
Keeping this species requires considerably more than ordinary reptile experience.
Before acquisition, a prospective keeper should already have:
- Appropriate specialist venomous-reptile experience
- Secure purpose-built accommodation
- Secondary containment
- Effective escape prevention
- Written emergency procedures
- Appropriate veterinary arrangements
- Knowledge of appropriate emergency medical facilities
- A plan for accidental escape
- A plan should the primary keeper become incapacitated
- Appropriate legal permissions where required
- A responsible backup person who knows what animals are present and how to summon appropriate assistance
The animal should never be acquired before these systems are in place.
SPECIES OVERVIEW
The Puff Adder is one of Africa’s most widespread vipers.
Its geographic range includes a remarkable variety of climates and habitats. The Reptile Database records the species across much of sub-Saharan Africa and into Morocco, south-western Saudi Arabia and Oman.
Habitats can include:
- Savannah
- Grassland
- Open woodland
- Scrub
- Semi-arid country
- Bushveld
- Agricultural areas
- Forest margins
- Rocky areas
The species generally avoids the deepest rainforest and the most extreme desert environments.
Puff Adders are ambush predators.
Their cryptic colouration allows them to remain exceptionally difficult to detect against:
- Soil
- Leaf litter
- Dry vegetation
- Grass
- Rocks
Normal behaviour may include:
- Remaining motionless for long periods
- Basking
- Slow deliberate movement
- Nocturnal movement
- Defensive inflation
- Loud hissing
The common name comes from the characteristic inflation and forceful hissing displayed when threatened.
However:
HISSING IS A WARNING BEHAVIOUR — NOT A GUARANTEED PRE-STRIKE SIGNAL.
The snake’s behaviour should never be relied upon as a safety system.
ADULT SIZE & LIFESPAN
Most adults are approximately:
3–4 ft (90–120 cm)
although larger animals occur.
Females may become particularly:
- Broad
- Heavy
- Substantial
The naturally robust body shape can make obesity difficult to recognise.
LIFESPAN
Approximately:
12–18+ years
may be achievable in captivity.
The commitment involved should therefore be considered before acquisition.
ENCLOSURE
Puff Adders are terrestrial.
Floor space is substantially more important than excessive height.
For a substantial adult, approximately:
5 × 2.5 × 2 ft
(approximately 150 × 75 × 60 cm)
should be regarded as a practical modern starting point.
Larger accommodation is encouraged where it can be safely managed.
The enclosure should allow the animal to:
- Move freely
- Fully reposition its body
- Thermoregulate
- Use multiple secure resting positions
- Retreat from illumination
- Access water
- Remain separated from the keeper during routine servicing where possible
SECURITY
Accommodation for any dangerously venomous snake requires substantially greater security than a conventional pet-snake enclosure.
The enclosure should be:
- Robust
- Escape-resistant
- Lockable
- Resistant to accidental opening
- Appropriately identified
- Located within a secure dedicated room or facility
All:
- Doors
- Sliding panels
- Vents
- Cable openings
- Service ports
must be designed so the snake cannot exploit them.
A small gap that would be irrelevant for a large adult may still matter for a juvenile.
SECONDARY CONTAINMENT
The enclosure itself should not be the only barrier preventing escape into an uncontrolled area.
A secure reptile room or equivalent facility should provide secondary containment.
The principle is:
PRIMARY ENCLOSURE + SECONDARY ROOM CONTAINMENT
Unauthorised people should not have access to the secure area.
ROUTINE HUSBANDRY DESIGN
Good venomous husbandry begins with enclosure design.
Routine tasks such as:
- Refilling water
- Spot cleaning
- Inspection
- Equipment maintenance
should be possible while minimising unnecessary exposure to the snake.
Secure retreat areas or separated enclosure sections can make routine servicing considerably safer.
A well-designed enclosure reduces the number of occasions on which the animal needs to be physically moved.
JUVENILE ENCLOSURES
Juveniles require secure accommodation scaled appropriately to their size.
They should still receive:
- Appropriate thermal gradient
- Secure retreats
- Suitable humidity
- Ventilation
- Clean water
- Appropriate lighting
- Absolute escape prevention
A juvenile Puff Adder is fully venomous.
Its small size does not reduce the need for specialist containment.
TEMPERATURE & HEATING
Puff Adders should be provided with a thermal gradient rather than maintained uniformly warm.
AMBIENT TEMPERATURE
Approximately:
24–28°C (75–82°F)
WARM AREA
Provide a local warm resting or basking area around:
30–32°C (86–90°F)
COOL RETREAT
Approximately:
22–25°C (72–77°F)
NIGHT
Approximately:
21–24°C (70–75°F)
Current specialist captive guidance supports these ranges as useful general targets.
LOCALITY MATTERS
Bitis arietans occurs across a vast geographic range.
Animals originating from:
- Arid regions
- Temperate southern populations
- Tropical East Africa
- Coastal areas
- Higher elevations
may experience different seasonal conditions.
Where locality is known, retain it and investigate the climate associated with that population.
Do not assume every Puff Adder should receive identical seasonal cycling.
OVERHEATING
Avoid heating the entire enclosure to the warm-area temperature.
A snake must be able to move between:
WARM AREA → MODERATE AREA → COOL RETREAT
Excessive heat combined with inability to retreat can cause:
- Dehydration
- Chronic stress
- Neurological compromise
- Death
HEATING EQUIPMENT
Suitable options may include:
- Secure overhead radiant heating
- Radiant heat panels
- Appropriately protected ceramic heating
- Controlled room heating
All heating systems should be:
- Thermostatically controlled
- Protected from direct animal contact
- Securely installed
- Checked independently with thermometers
Avoid:
- Heat rocks
- Exposed heating elements
- Uncontrolled heat mats
MEASURING TEMPERATURES
Use reliable digital probe thermometers.
Monitor at least:
- Warm area
- General ambient area
- Cool retreat
An infrared thermometer is useful for checking surface temperatures.
Remember:
THE THERMOSTAT SETTING IS NOT THE SAME AS THE ACTUAL ENCLOSURE TEMPERATURE.
Measure the conditions at snake level.
HUMIDITY
Because Puff Adders inhabit such a broad geographic range, humidity should not be treated as one universal fixed figure.
For many savannah and woodland localities, approximately:
40–60% relative humidity
provides a useful general starting range.
A more humid retreat around:
60–75%
can be useful during shedding.
The snake should still be maintained on a generally dry surface rather than constantly wet substrate.
HUMIDITY GRADIENT
A well-designed enclosure can provide:
drier exposed surface → moderate ambient humidity → locally more humid retreat
This is preferable to repeatedly soaking the entire enclosure.
HUMIDITY DOES NOT MEAN WET
Persistent dampness can contribute to:
- Dermatitis
- Scale problems
- Fungal growth
- Bacterial growth
- Respiratory disease
Keep the main surface reasonably dry.
Moisture can be retained deeper in the substrate or within a dedicated humid retreat where appropriate.
VENTILATION
Good ventilation is essential.
Avoid creating:
WARM + DAMP + STAGNANT
conditions.
The objective is:
APPROPRIATE HUMIDITY + GOOD AIR EXCHANGE
WATER
Fresh clean water should remain available continuously.
Use a water container that is:
- Stable
- Difficult to overturn
- Appropriately sized
- Positioned for safe servicing
Replace contaminated water promptly.
Some individuals may soak, particularly around shedding.
SUBSTRATE
Suitable substrates can include:
- Appropriate soil-based mixes
- Cypress-type mulch
- Aspen in appropriately dry setups
- Coco-based mixes used carefully
- Suitable bark products
A naturalistic mixture can be particularly useful.
The substrate should:
- Provide traction
- Remain relatively low-dust
- Allow some moisture gradient
- Be easy to spot-clean
- Avoid remaining permanently saturated
LEAF LITTER & COVER
Naturalistic ground cover can include:
- Dry leaves
- Cork pieces
- Low vegetation
- Stable low hides
- Visual barriers
Cover provides:
- Security
- Environmental complexity
- More natural resting behaviour
However, furnishings should not make it impossible to locate the snake before the enclosure is serviced.
HIDES
Provide at least:
- Warm secure retreat
- Cool secure retreat
A more humid retreat can also be useful, particularly during shedding.
A Puff Adder should not have to choose between:
SECURITY
and:
CORRECT TEMPERATURE
LIGHTING
Provide a clear day/night cycle.
Approximately:
10–12 hours of daytime illumination
is appropriate.
The enclosure should become properly dark at night.
Avoid visible:
- Red
- Blue
- Purple
night lighting.
UVB
Puff Adders are not intense high-UVI basking reptiles.
They spend substantial time:
- Beneath vegetation
- In grass
- Under cover
- Active during lower-light periods
Low-level UVB may nevertheless be offered over part of the enclosure as part of comprehensive modern husbandry.
Specialist guidance describes this as a low-exposure/Ferguson Zone 1 opportunity rather than an essential high-output setup.
The snake must always be able to remain completely shaded.
TARGET UVI
A practical low-level target is approximately:
UVI 0.5–1.5
in an accessible illuminated area.
Provide:
LOWER UV → SHADE → COMPLETE UV RETREAT
elsewhere.
PRACTICAL UVB EQUIPMENT GUIDANCE
A quality:
LOW-OUTPUT LINEAR UVB SYSTEM
can provide appropriate exposure.
The exact lamp required depends upon:
- Enclosure height
- Lamp model
- Reflector
- Distance
- Mesh
- Lamp age
- Mounting position
The target is approximately:
UVI 0.5–1.5 AT SNAKE LEVEL
rather than a particular percentage printed on the lamp.
WHY PERCENTAGE ALONE IS NOT ENOUGH
Two keepers can use the same UVB tube but produce very different exposure.
In general:
CLOSER = MORE UV
FARTHER AWAY = LESS UV
MESH = USUALLY LESS UV
A lower-output tube installed relatively close can sometimes provide more UV at the animal than a stronger tube positioned much farther away.
This is why the actual UVI matters.
UV GRADIENT
A suitable arrangement can provide:
ILLUMINATED AREA: UVI approximately 0.5–1.5
↓
LOWER-UV AREA: Below UVI 0.5
↓
FULL SHADE: Approaching UVI 0
Do not illuminate the entire enclosure with UVB.
UV METER
An appropriate UV Index meter is the best way to verify actual exposure.
Measure approximately:
AT THE HEIGHT OF THE SNAKE
rather than directly beneath the lamp.
IF A UV METER IS NOT AVAILABLE
Use:
- A reputable linear UVB product
- Manufacturer’s current distance guidance
- Correct reflector
- Correct mesh guidance
- Extensive shaded areas
Do not compensate for uncertainty by installing an unnecessarily powerful lamp.
HEAT, UVB & VISIBLE LIGHT
These are separate components.
HEATING SYSTEM = WARMTH
UVB SYSTEM = ULTRAVIOLET
DAYLIGHT LIGHTING = VISIBLE LIGHT
One does not automatically replace another.
FEEDING
Puff Adders are ambush predators.
Rodents make up a major proportion of the natural diet; one dietary study cited by the Reptile Database found rodents comprised approximately 76% of prey.
Captive animals can generally be maintained successfully on appropriately sized whole rodents.
Suitable prey may include:
- Mice for small juveniles
- Rats for larger animals
- Other appropriate whole prey where justified
Dietary variety can be offered, but nutritional adequacy and appropriate body condition are more important than constantly changing prey species.
FROZEN-THAWED PREY
Where accepted:
APPROPRIATELY PREPARED FROZEN-THAWED PREY
is preferable to routine live vertebrate feeding.
Live rodents can injure snakes.
PREY SIZE
Avoid routinely feeding excessively large prey.
A moderate meal is preferable to extreme distension.
Large ambush vipers are capable of consuming substantial prey, but this does not mean maximal prey size produces better health.
FEEDING FREQUENCY
Puff Adders have relatively slow metabolisms.
Current specialist captive guidance commonly uses moderate whole-prey feeding rather than frequent meals.
JUVENILES
Approximately:
every 7–14 days
depending upon:
- Prey size
- Growth
- Body condition
SUBADULTS
Approximately:
every 14–21 days
may be suitable.
ADULTS
Many healthy adults may be fed approximately:
every 2–4 weeks
depending upon:
- Meal size
- Sex
- Activity
- Season
- Body condition
These are guidelines rather than rigid schedules.
OBESITY
Puff Adders are naturally thick-bodied.
This makes excessive weight easy to overlook.
A healthy animal should be:
ROBUST AND MUSCULAR
rather than simply very fat.
Chronic overfeeding may contribute to:
- Reduced mobility
- Excessive fat deposition
- Organ disease
- Poor reproductive health
- Reduced longevity
Monitor:
- Weight trends
- Body contour
- Activity
- Feeding history
FEEDING RESPONSE & SAFETY
Puff Adders are ambush predators with extremely rapid strikes.
Routine husbandry should be designed to minimise unnecessary exposure during feeding.
Food should not be presented directly by hand.
This care sheet deliberately does not provide step-by-step venomous-snake manipulation techniques.
Specialist practical competence is required for safe management.
HANDLING & TEMPERAMENT
Puff Adders should not be casually handled.
Normal defensive behaviour may include:
- Body inflation
- Loud hissing
- Remaining motionless
- Sudden striking
The characteristic hiss can create a dangerous misconception that a Puff Adder will always provide warning before a strike.
Never rely upon this.
A quiet Puff Adder is still dangerous.
Routine husbandry should focus on:
SECURE SYSTEMS + MINIMAL DIRECT INTERACTION
rather than testing the temperament of the animal.
COHABITATION
Individual housing is recommended.
Benefits include easier monitoring of:
- Feeding
- Weight
- Faeces
- Shedding
- Behaviour
- Health
It also reduces unnecessary complexity and risk.
Temporary reproductive introductions are different from routine permanent housing.
CLEANING & ROUTINE CARE
Regularly inspect:
- Water
- Faeces
- Urates
- Shed skin
- Substrate condition
- Humidity
- Temperatures
- Equipment
- Signs of mites
- General behaviour
Spot-clean contamination promptly.
The enclosure should be designed so routine maintenance can occur without unnecessary exposure to an uncontained venomous animal.
QUARANTINE
New animals should undergo strict quarantine.
Approximately:
90 DAYS MINIMUM
is a sensible starting point.
Longer may be appropriate for:
- Wild-caught animals
- Imports
- Animals of uncertain origin
- Animals showing clinical problems
Current specialist husbandry guidance particularly highlights risks including mites, internal parasites, dehydration, stomatitis and respiratory disease in imports.
Use dedicated:
- Water bowls
- Cleaning tools
- Husbandry equipment
where practical.
Monitor:
- Weight
- Appetite
- Faeces
- Shedding
- Respiration
- Oral appearance
- Skin
- Behaviour
Veterinary examination and parasite screening are strongly recommended.
COMMON HEALTH CONCERNS
OBESITY
One of the most preventable captive problems.
Control feeding according to body condition.
RESPIRATORY DISEASE
Possible signs include:
- Wheezing
- Clicking
- Nasal discharge
- Excess mucus
- Persistent abnormal open-mouth breathing
Potential contributors include:
- Excessive cooling
- Poor ventilation
- Persistently damp conditions
STOMATITIS
Possible signs include:
- Swelling
- Oral discharge
- Abnormal mouth position
- Damaged tissue
Veterinary treatment is required.
SKIN DISEASE
Persistently damp, dirty substrate can contribute to:
- Dermatitis
- Scale damage
- Bacterial infection
PARASITES
Particularly important in imported or wild-caught animals.
Signs may include:
- Weight loss
- Poor condition
- Abnormal faeces
- Visible mites
- Reduced feeding
DYSECDYSIS
Poor shedding may result from:
- Inappropriate humidity
- Dehydration
- Parasites
- Underlying illness
Provide an appropriate humid microclimate rather than saturating the entire enclosure.
SIGNS OF GOOD HEALTH
A healthy Puff Adder should generally show:
- Clear eyes outside shedding
- Clean nostrils
- Quiet respiration
- Intact scales
- Good muscle tone
- Appropriate body condition
- Normal tongue-flicking
- Appropriate feeding response
- Normal faeces
- Healthy shedding
WHEN TO SEEK VETERINARY ADVICE
Consult a veterinarian appropriately equipped to manage venomous reptiles for:
- Respiratory symptoms
- Oral or nasal discharge
- Significant unexplained weight loss
- Severe lethargy
- Regurgitation
- Persistent abnormal food refusal
- Skin lesions
- Burns
- Abnormal swelling
- Persistent abnormal faeces
- Injuries
- Reproductive problems
- Major unexplained behavioural changes
VETERINARY PLANNING
An appropriate veterinarian should be identified before acquiring the animal.
A veterinary practice that treats reptiles may still not be equipped to safely manage a dangerously venomous snake.
The practice should know:
- Exact species
- Venomous status
- Approximate size
- Reason for presentation
before the animal is brought to the premises.
Never arrive unexpectedly at a clinic carrying a venomous snake.
EMERGENCY PLANNING
A written emergency plan should exist before the snake enters the facility.
It should identify:
- Exact species present
- Appropriate emergency medical arrangements
- Relevant emergency contacts
- What happens if the keeper is incapacitated
- Who is appropriately competent to assist with the animal if necessary
Other responsible people associated with the premises should know that venomous reptiles are present and know how to summon appropriate assistance without entering the secure reptile area.
Any suspected Puff Adder bite requires:
IMMEDIATE EMERGENCY MEDICAL ASSESSMENT.
Do not rely on improvised home treatment.
ESCAPE PLANNING
The facility should also have a written escape procedure.
The secure room should be designed to reduce the chance that an escaped snake could leave the dedicated reptile area.
People without appropriate specialist competence should not attempt to capture an escaped Puff Adder.
Good containment should make escape extremely unlikely in the first place.
BREEDING
Puff Adders are:
VIVIPAROUS — LIVE-BEARING
The Reptile Database records live-bearing reproduction for the species.
Breeding should only be undertaken by appropriately experienced venomous-reptile keepers with:
- Mature healthy animals
- Secure breeding facilities
- Separate accommodation for offspring
- Appropriate emergency planning
- Legal compliance
- A realistic plan for every neonate produced
SEXUAL DIMORPHISM
Females generally become:
- Larger
- Broader
- Heavier
than males.
Physical sex determination should only be performed by appropriately competent people familiar with venomous reptiles.
SEASONALITY
The enormous distribution of the species means breeding seasonality varies by locality.
Potential environmental influences include:
- Temperature
- Photoperiod
- Rainfall
- Humidity
- Feeding
Known locality information is therefore valuable.
Do not apply one extreme generic cooling regime to animals from every population.
GESTATION
Gestation is prolonged.
A gravid female may:
- Become considerably broader
- Reduce feeding
- Alter basking behaviour
- Change thermal preference
- Spend longer resting
Excellent body condition before breeding is important.
LITTER SIZE
Puff Adders are capable of producing:
VERY LARGE LITTERS.
Litter size can vary enormously and several dozen offspring are possible.
Exceptionally large litters have been reported.
Anyone considering breeding should be prepared for the possibility of producing a very substantial number of venomous neonates.
NEONATES
Newborn Puff Adders are:
VENOMOUS FROM BIRTH.
Each neonate requires appropriate secure containment from the moment it is born.
Breeding therefore requires advance planning for:
- Individual secure accommodation
- Identification
- Record keeping
- Feeding
- Long-term placement
- Legal compliance
A large litter should never be produced without facilities already available.
LEGAL CONSIDERATIONS — REPUBLIC OF IRELAND
The Republic of Ireland is not governed by the UK’s Dangerous Wild Animals Act.
A British DWA licence should therefore never be presented as a legal requirement for keeping a Puff Adder in the Republic of Ireland.
However, anyone acquiring, keeping, breeding, transporting, importing, exporting or transferring a venomous reptile in the Republic of Ireland must check all legislation and requirements applicable at the time.
Relevant considerations can include:
- Animal health and welfare legislation
- Import and export requirements
- CITES requirements where applicable
- Transport requirements
- Public safety obligations
- Property, tenancy or insurance restrictions
The legal position should be verified before acquisition or transfer rather than relying upon assumptions based on UK legislation.
LEGAL CONSIDERATIONS — NORTHERN IRELAND
Northern Ireland has its own dangerous wild animal legislation.
DAERA’s guidance on venomous snakes is issued under the:
Dangerous Wild Animals (Northern Ireland) Order 2004.
A prospective keeper must check the current licensing requirements and obtain the required authorisation before acquiring a covered animal.
The Northern Ireland system should not be confused with the legislation applying in Great Britain.
LEGAL CONSIDERATIONS — GREAT BRITAIN
In Great Britain, dangerous wild animal keeping is governed by the:
Dangerous Wild Animals Act 1976
and the applicable current schedule and subsequent legislation.
Viperidae are included within the dangerous-wild-animal schedule.
Anyone intending to keep a Puff Adder in England, Scotland or Wales should verify the current requirements with the relevant local authority before acquiring the animal.
IMPORTANT JURISDICTION DISTINCTION
For readers in Ireland and the UK:
REPUBLIC OF IRELAND ≠ NORTHERN IRELAND ≠ GREAT BRITAIN
Their legal frameworks are not interchangeable.
Compliance in one jurisdiction does not automatically establish compliance in another.
This becomes particularly important when animals are:
- Purchased
- Sold
- Transported
- Imported
- Exported
- Moved between jurisdictions
RESPONSIBLE OWNERSHIP CHECKLIST
Before acquiring a Puff Adder, ensure you can provide:
- Specialist venomous-reptile experience
- Secure dedicated reptile facility
- Lockable escape-resistant enclosure
- Secondary containment
- Approximately 5 × 2.5 × 2 ft or larger adult accommodation
- Correct thermal gradient
- Appropriate humidity for the animal’s locality
- Good ventilation
- Clean drinking water
- Secure hides
- Suitable substrate
- Appropriate visible lighting
- Low-level optional UVB
- Whole-prey feeding
- Controlled body condition
- Strict quarantine
- Specialist veterinary arrangements
- Written bite emergency plan
- Written escape plan
- Responsible backup arrangements
- Secure transport arrangements
- Correct legal permissions
- Long-term financial resources
COMMON HUSBANDRY MISTAKES
Assuming a Puff Adder will always hiss before striking
Never rely on warning behaviour.
Assuming stillness means safety
An ambush predator may remain motionless until it reacts.
Enclosure too small
Provide meaningful floor space and a genuine thermal gradient.
Keeping the whole enclosure too warm
A cool retreat is essential.
Using Gaboon Viper humidity for every Puff Adder
Puff Adders occupy many drier environments.
Keeping substrate permanently wet
Most individuals require a predominantly dry surface.
No humid retreat during shedding
Provide a local moisture option where appropriate.
Poor ventilation
Avoid stagnant conditions.
No cover
Provide secure retreats and visual cover.
Using high-intensity desert UVB
Only low-level optional UVB is appropriate.
Choosing UVB solely by lamp percentage
Actual UVI at the animal matters.
Overfeeding
Heavy-bodied does not mean obese.
Casual handling
This is a dangerously venomous species.
Depending upon temperament for safety
Containment systems should provide safety.
No secondary containment
Use a secure surrounding room or facility.
No emergency plan
Planning must occur before acquisition.
No veterinary plan
Identify appropriate veterinary support in advance.
Breeding without planning for large litters
Puff Adders can produce many venomous neonates.
Assuming UK DWA legislation applies in the Republic of Ireland
It does not.

PRACTICAL UVB SUMMARY
Puff Adders require only:
LOW-LEVEL OPTIONAL UVB + EXTENSIVE SHADE.
A quality linear UVB system may be used to create approximately:
UVI 0.5–1.5
in part of the usable enclosure.
The exact lamp depends upon:
- Lamp model
- Reflector
- Distance
- Mesh
- Installation
Remember:
CLOSER = GENERALLY MORE UV
FARTHER AWAY = GENERALLY LESS UV
MESH = USUALLY LESS UV
and:
HEAT = TEMPERATURE
UVB = ULTRAVIOLET
DAYLIGHT LIGHTING = VISIBLE LIGHT
Do not expose the entire enclosure to UVB.
The snake should always be able to remain completely shaded.
IMPORTANT INFORMATION
This care sheet provides general husbandry guidance and does not replace species-specific research, specialist practical training, legal advice or veterinary advice. Individual requirements may vary, particularly because Bitis arietans occupies an exceptionally broad geographic range.
The Puff Adder is a dangerously venomous snake capable of causing severe and potentially fatal envenomation. It is suitable only for appropriately experienced specialist keepers with secure facilities, emergency procedures and all legally required permissions.
This care sheet deliberately does not provide step-by-step instructions for handling, restraint or physical manipulation of venomous snakes.
The Dangerous Wild Animals legislation applicable in Great Britain does not apply in the Republic of Ireland. Northern Ireland has separate dangerous wild animal legislation. Always verify the current requirements for the jurisdiction in which the animal will actually be kept.
Captive-bred animals of documented provenance should be strongly preferred.
If you have concerns about an animal’s health or care, consult a suitably experienced reptile veterinarian who is prepared and equipped to work with dangerously venomous reptiles.
Information correct at the date of publication.
