COMMON / ASIAN HOUSE GECKO (HEMIDACTYLUS FRENATUS) CARE SHEET
The Common House Gecko (Hemidactylus frenatus), also widely called the Asian House Gecko or South Asian House Gecko, is one of the most successful and widely distributed gecko species in the world.
Originally associated with tropical and subtropical Asia and the Indo-Pacific, it has been transported extensively by humans and is now established across many tropical and subtropical regions worldwide.
Its success around human habitation has sometimes led to the mistaken belief that it is a species requiring very little husbandry.
In captivity, however, it should be provided with the same standard of care expected for any other reptile: a secure vertically orientated enclosure, extensive climbing surfaces and hiding crevices, appropriate warmth, low-level UVB, moderate-to-high fluctuating humidity, excellent ventilation, reliable hydration and a varied diet of appropriately supplemented live invertebrates.
It is a fast, alert nocturnal gecko and should be regarded primarily as a display animal rather than a species for frequent handling.
Captive-bred animals should be preferred whenever available.

TAXONOMY
The accepted scientific name is:
Hemidactylus frenatus
The species was described by Duméril and Bibron in 1836 and remains recognised as a valid species.
It belongs to the diverse genus:
Hemidactylus
which contains many superficially similar house geckos.
Correct identification is therefore important.
COMMON NAMES
Common names include:
- Common House Gecko
- Asian House Gecko
- South Asian House Gecko
- Bridled House Gecko
- Chichak
Because “House Gecko” is used for numerous species, always use the scientific name when:
- Purchasing
- Breeding
- Recording locality
- Researching husbandry
NATURAL DISTRIBUTION
The species is native broadly across tropical and subtropical parts of:
- South Asia
- Southeast Asia
- East Asia
- Indonesia
- Philippines
- New Guinea
- Indo-Pacific islands
Its type locality is Java.
INTRODUCED DISTRIBUTION
Hemidactylus frenatus has been introduced to an extraordinary number of locations.
Established populations occur in parts of:
- Africa
- Madagascar region
- Australia
- Pacific islands
- Central America
- South America
- Caribbean islands
- United States
- Galápagos Islands
among many others.
INVASIVE POTENTIAL
This species is particularly important from an ecological perspective.
In some introduced areas it competes strongly with native geckos.
The Reptile Database notes that its arrival in the Mascarene Islands was associated with severe declines and extinctions within native Nactus gecko populations.
For this reason:
never release captive Common House Geckos outdoors.
IDENTIFICATION
Typical characteristics include:
- Grey, beige or light brown body
- Irregular darker markings
- Pale underside
- Broad adhesive toe pads
- Large lidless eyes
- Vertical pupils
- Relatively smooth body compared with some other house geckos
- Tail often showing bands or mottling
Colour can change significantly depending upon:
- Temperature
- Background
- Stress
- Light level
NATURAL HABITAT
Common House Geckos are extraordinarily adaptable.
They occupy:
- Tropical forest edges
- Tree trunks
- Rock faces
- Buildings
- Walls
- Ceilings
- Roof spaces
- Fences
- Artificial structures
HUMAN-ASSOCIATED HABITAT
They frequently thrive around human settlement.
Common resting sites include:
- Roof cavities
- Wall gaps
- Window frames
- Behind signs
- Beneath shutters
- Crevices in masonry
ARTIFICIAL LIGHTS
Wild individuals commonly congregate around lights at night.
Artificial lights attract insects such as:
- Moths
- Flies
- Beetles
- Mosquitoes
The geckos exploit these feeding opportunities.
This does not mean night lighting should remain illuminated in captivity.
ACTIVITY
The species is primarily:
nocturnal.
Activity usually increases around dusk.
VOCALISATION
Common House Geckos are relatively vocal.
Males may produce:
- Chirps
- Clicks
- Short repetitive calls
Vocalisation plays a role in:
- Territorial behaviour
- Courtship
- Social communication
ENCLOSURE SIZE
For one adult, provide at least approximately:
18 × 18 × 24 in (45 × 45 × 60 cm).
Larger accommodation is preferable.
An enclosure around:
18 × 18 × 36 in (45 × 45 × 90 cm)
provides excellent additional vertical space.
WHY NOT USE A VERY SMALL ENCLOSURE?
Although small geckos can physically survive in tiny containers, appropriate long-term housing should allow:
- Climbing
- Hunting
- Thermoregulation
- UV regulation
- Hiding
- Exploration
- Behavioural choice
ENCLOSURE ORIENTATION
Use a:
vertically orientated enclosure.
This species spends much of its time above ground.
ENCLOSURE TYPE
Suitable options include:
- Glass arboreal terrariums
- PVC arboreal vivariums
- Purpose-built tropical enclosures
- Naturalistic planted vivariums
ESCAPE SECURITY
Escape prevention is extremely important.
House Geckos are:
- Fast
- Small
- Flattened
- Excellent climbers
- Able to adhere to smooth surfaces
Check:
- Door gaps
- Cable holes
- Mesh seams
- Ventilation openings
- Sliding-door tracks
- Background gaps
HATCHLING ESCAPE RISK
Hatchlings can squeeze through openings that appear impossibly small.
Any enclosure used for juveniles must be especially secure.
FURNISHINGS
Provide abundant:
- Cork flats
- Cork tubes
- Natural branches
- Vines
- Vertical bark
- Rock-effect surfaces
- Crevices
- Live plants
- Dense foliage
VERTICAL SURFACES
Large vertical surfaces are extremely useful.
These geckos naturally spend much of their time on:
- Walls
- Tree trunks
- Bark
- Rock faces
HIDES
Provide several hides at different heights.
Useful retreats include:
- Cork tubes
- Narrow bark gaps
- Artificial rock crevices
- Plant cover
CREVICE SECURITY
House Geckos often prefer tight retreats where much of the body contacts surrounding surfaces.
Loose open shelters are less useful than genuine narrow crevices.
BRANCHES
Provide branches in several orientations:
- Vertical
- Diagonal
- Horizontal
FOLIAGE
Dense foliage provides:
- Security
- Drinking surfaces
- Visual barriers
- Humidity retention
- Shade
- UV refuge
LIVE PLANTS
Suitable plants may include:
- Pothos
- Ficus
- Schefflera
- Philodendron
- Dracaena
- Other safe tropical plants
PLANT SAFETY
Avoid plants recently treated with:
- Insecticides
- Systemic pesticides
- Miticides
- Herbicides
- Leaf-polishing products
Prepare plants appropriately before introduction.
TEMPERATURE
Maintain much of the enclosure during the day around:
77–84°F (25–29°C).
WARM AREA
Provide a warmer upper area around:
86–90°F (30–32°C).
This should occupy only part of the enclosure.
THERMAL GRADIENT
The enclosure should provide:
warm zone → moderate zone → cooler shaded zone.
Do not maintain every surface at the same temperature.
NIGHT TEMPERATURE
Allow nighttime temperatures to fall to approximately:
70–77°F (21–25°C).
Healthy adults can tolerate brief modest drops below this range, but chronic cool conditions are inappropriate for this tropical species.
OVERHEATING
Avoid allowing the entire enclosure to remain above:
86°F (30°C).
Even tropical reptiles require cooler retreat areas.
HEATING
Where additional heating is required, use:
thermostatically controlled overhead heating.
Possible options include:
- Low-wattage halogen lamp
- Appropriate radiant heating
UNDER-TANK HEATING
Under-tank heating is not ideal as a primary heat source for this strongly arboreal species.
Most useful thermal opportunities should occur above ground.
THERMOSTAT
Every significant heating source should be controlled by an:
appropriate thermostat.
TEMPERATURE MONITORING
Use digital thermometers at:
- Upper warm area
- Mid enclosure
- Lower cool area
An infrared thermometer is useful for checking surface temperatures.
LIGHTING
Provide a clear photoperiod.
Approximately:
12 hours light / 12 hours dark
is suitable for routine husbandry.
NIGHT LIGHTING
Provide true darkness at night.
Do not use permanently illuminated:
- Red lamps
- Blue lamps
- Purple lamps
- Moonlight bulbs
UVB
Low-level UVB is recommended.
Although primarily nocturnal, Common House Geckos commonly shelter close to openings and exposed surfaces where low levels of UV may be available naturally.
UV INDEX
A suitable target is approximately:
UVI 1–2
at accessible exposed upper positions.
Provide abundant shade approaching:
UVI 0.
UVB EQUIPMENT
A:
low-output linear UVB lamp
is generally appropriate.
The exact lamp depends upon:
- Distance
- Mesh
- Reflector
- Enclosure height
- Plant cover
MESH REDUCTION
Mesh can reduce UVB output considerably.
The percentage printed on a UVB lamp does not directly tell you the UVI reaching the animal.
UV METER
Where possible, measure actual UVI using an appropriate UV meter.
Measure at the branch or wall surface where the gecko can physically sit.
HUMIDITY
Maintain general humidity around:
55–75%.
HUMIDITY AFTER MISTING
Humidity can temporarily rise toward:
75–90%
following misting.
Allow it to decrease again as surfaces dry.
HUMIDITY CYCLE
A healthy pattern is:
mist → humidity rises → drinking droplets remain → enclosure gradually dries → repeat.
DO NOT KEEP THE ENCLOSURE SATURATED
Permanently wet conditions can encourage:
- Bacterial growth
- Fungal growth
- Skin disease
- Respiratory disease
- Mould
VENTILATION
Excellent ventilation is essential.
Warm tropical conditions combined with stagnant humidity are particularly problematic.
MISTING
Light misting:
once daily or several times per week
may be appropriate depending upon:
- Ventilation
- Ambient room humidity
- Temperature
- Planting
In dry homes, twice-daily light misting may sometimes be necessary.
EVENING MISTING
An evening mist shortly before or around lights-out is particularly useful because it provides drinking droplets as the gecko becomes active.
DRINKING
Common House Geckos frequently lick droplets from:
- Glass
- Bark
- Plants
- Walls
WATER DISH
Provide:
fresh clean drinking water at all times.
A small elevated dish can be useful.
SUBSTRATE
Suitable substrate options include:
- Organic topsoil mixtures
- Coco-based tropical substrate
- Orchid bark
- Leaf litter
- Commercial tropical bioactive substrate
SUBSTRATE MOISTURE
Maintain the substrate:
slightly moist rather than saturated.
Allow upper layers to dry somewhat between misting periods.
DRAINAGE
A drainage layer is useful in heavily planted enclosures receiving frequent misting.
LEAF LITTER
Leaf litter helps provide:
- Moisture buffering
- Natural cover
- Microfauna habitat
- Enrichment
BIOACTIVE HOUSING
Common House Geckos can be maintained successfully in bioactive enclosures.
Suitable clean-up crew organisms include:
- Springtails
- Small tropical isopods
BIOACTIVE DOES NOT MEAN MAINTENANCE-FREE
Continue to:
- Clean water dishes
- Remove dead feeder insects
- Monitor drainage
- Maintain plants
- Remove excessive waste
- Inspect equipment

They can:
- Disturb resting geckos
- Bite animals
- Damage plants
BODY CONDITION
Monitor:
- Weight
- Tail base
- Muscle condition
- Grip strength
- Activity
- Feeding response
A small digital gram scale is useful.
HANDLING
Common House Geckos should primarily be regarded as:
display animals.
WHY MINIMAL HANDLING?
They are:
- Fast
- Easily stressed
- Capable of jumping
- Vulnerable to tail loss
- Very difficult to recapture after escape
NECESSARY TRANSFERS
When movement is required:
- Work in a secure closed room
- Close windows
- Move slowly
- Encourage the gecko into a container
- Avoid grabbing
- Keep handling brief
TAIL AUTOTOMY
Never restrain a Common House Gecko by:
the tail.
The tail may detach as an anti-predator defence.
REGENERATED TAIL
A regenerated tail can differ from the original in:
- Shape
- Pattern
- Texture
- Colour
SOCIAL BEHAVIOUR
This species can show considerable social and territorial behaviour.
Males may:
- Call
- Chase rivals
- Defend preferred areas
- Bite competing males
SOCIAL HOUSING
Individual housing is the:
safest default.
MALES
Do not routinely house:
adult males together.
Territorial conflict can result in:
- Bite wounds
- Chronic stress
- Reduced feeding
- Exclusion from preferred areas
FEMALES
Females may sometimes coexist in large, densely structured enclosures.
However, group housing can make it difficult to monitor individual:
- Feeding
- Weight
- Reproduction
- Faeces
MALE/FEMALE PAIRS
Male/female pairs can breed readily.
Permanent pair housing can lead to repeated reproductive pressure on the female.
Separate housing allows better breeding control.
SEXING
Adult males typically possess:
- Distinct preanal pores
- Hemipenal bulges
Females lack prominent hemipenal bulges.
BREEDING
The species is:
oviparous.
In tropical climates breeding can occur for much of the year.
BREEDING FEMALES
Females intended for breeding should have excellent:
- Body condition
- Calcium reserves
- Hydration
- Nutrition
- Vitamin status
COURTSHIP
Courtship may involve:
- Male approach
- Snout contact
- Vocalisation
- Neck gripping
Males may briefly hold females around the neck during mating.
EGG PRODUCTION
Females typically produce:
two eggs per clutch.
These eggs are:
- Rounded
- Hard-shelled
- Usually deposited together
Published accounts describe females depositing two eggs several weeks after fertilisation.
EGG-LAYING SITES
Eggs may be deposited in:
- Crevices
- Beneath bark
- Behind enclosure furnishings
- Rock gaps
- Cork tubes
- Sheltered elevated surfaces
EGG ADHESION
The eggs can become:
partly adhered to the laying surface.
Do not forcibly detach firmly attached eggs.
COMMUNAL NESTING
Multiple females may use the same suitable laying site.
This can result in groups of eggs accumulating within protected crevices.
REMOVABLE LAYING SURFACES
Useful breeding furnishings include:
- Removable cork panels
- Bark pieces
- Narrow removable tubes
- Artificial crevice structures
These increase the chance that eggs can be relocated without damage.
INCUBATION TEMPERATURE
A useful captive incubation range is approximately:
79–84°F (26–29°C).
Avoid unnecessarily extreme incubation temperatures.
INCUBATION HUMIDITY
Maintain moderate-to-high humidity around the eggs without keeping them directly wet.
INCUBATION TIME
Incubation duration varies substantially with temperature.
Under warm conditions, hatching commonly occurs after approximately:
6–10 weeks.
Cooler conditions can extend incubation considerably.
TEMPERATURE AND SEX
Research on Hemidactylus frenatus indicates that incubation temperature can influence offspring sex.
For hobby husbandry, prioritise safe, stable incubation temperatures rather than pushing eggs to thermal extremes simply to manipulate sex ratio.
HATCHLING SIZE
Hatchlings are very small and require exceptionally secure accommodation.
HATCHLING HOUSING
Provide:
- Fine branches
- Vertical cork
- Small hides
- Dense foliage
- Fresh water
- Appropriate humidity

SUMMARY
The Common / Asian House Gecko (Hemidactylus frenatus) is a small, highly adaptable nocturnal gecko originally associated with tropical and subtropical Asia and the Indo-Pacific but now introduced throughout much of the tropical world.
For one adult, provide at least approximately:
18 × 18 × 24 in (45 × 45 × 60 cm),
with larger vertically orientated housing preferred.
Provide abundant:
- Cork
- Vertical surfaces
- Branches
- Crevices
- Dense foliage
- Elevated hiding areas
Maintain daytime temperatures primarily around:
77–84°F (25–29°C)
with a limited warmer area around:
86–90°F (30–32°C).
Allow nighttime temperatures to fall to approximately:
70–77°F (21–25°C).
Maintain humidity generally around:
55–75%
with temporary higher peaks after misting and partial drying between misting periods.
Excellent ventilation is essential.
Provide low-level UVB with approximately:
UVI 1–2
at exposed upper positions and shaded retreats approaching zero.
Feed a varied diet of appropriately sized, gut-loaded and correctly supplemented live insects.
Fresh drinking water should always be available.
Individual housing is the safest default, particularly for males.
Females generally produce:
two hard-shelled eggs per clutch.
The species breeds readily under suitable tropical conditions and may reproduce throughout much of the year.
Handling should be minimal.
Captive-bred animals should be preferred whenever possible.
Because H. frenatus is an exceptionally successful introduced species and has negatively affected native reptiles in some ecosystems, secure containment and responsible ownership are particularly important.
