Mediterranean House Gecko

Hemidactylus turcicus

The Mediterranean house gecko is a small, pale, translucent-skinned nocturnal gecko best known outside the pet trade for the chirping calls it makes around porch lights on warm nights across much of the southern US, where it's become a familiar, naturalized 'commensal' species living alongside people rather than a deliberately introduced pet import. In the hobby, it's a genuinely low-cost, low-footprint, hardy beginner gecko β€” smaller and simpler to house than a leopard gecko or crested gecko β€” though its thin, delicate skin and famously easy tail-drop reflex mean it needs gentler, more minimal handling than either of those more robust, more commonly recommended beginner species.

Lifespan

5-9 years in captivity with correct husbandry

Size

4-5 inches total length as an adult, including a proportionally long, thin tail

Origin

Native to the Mediterranean basin (southern Europe, North Africa, the Middle East); now widely naturalized around human structures across the southern United States and elsewhere through incidental introduction

Husbandry

Enclosure size
A 10-gallon (38L) enclosure comfortably houses a single adult, or a small same-species group given this gecko's naturally more tolerant, loosely social wild behavior around shared shelter and light sources
Source: Association of Reptilian and Amphibian Veterinarians (ARAV) husbandry guidance (checked 2026-07-13)
Temperature gradient
Ambient 75-85Β°F (24-29Β°C) with a modest basking area around 88Β°F (31Β°C); nighttime drop to 68-72Β°F (20-22Β°C) is well tolerated and reflects this species' Mediterranean climate origin

Humidity
50-60% ambient β€” moderate, with a slightly damp hide available for shedding support, though this species tolerates a drier range better than a tropical forest gecko would

UVB lighting
Low-level UVB (2-5%) is increasingly recommended for this crepuscular-to-nocturnal species, mirroring the same evolving practice applied to other nocturnal geckos on this site

Diet
Small gut-loaded insects sized to this gecko's small mouth β€” fruit flies for hatchlings, small crickets or roaches for adults β€” offered every 1-2 days
Source: ARAV husbandry guidance (checked 2026-07-13)
Supplementation
A light dusting of calcium without D3 on most feedings, with a calcium-D3-and-multivitamin combination worked in roughly weekly given this species' small size and correspondingly small margin for over-supplementation
Source: ARAV husbandry guidance (checked 2026-07-13)
Cohabitation
More tolerant of same-species company than most geckos on this site β€” small groups of females, or a male with several females, can often be housed together successfully, though males housed together will fight
Source: Merck Veterinary Manual β€” Reptile Husbandry (checked 2026-07-13)
Substrate
Paper towel, coconut fiber, or a thin layer of reptile-safe soil substrate all work well; this species doesn't burrow extensively, so substrate choice matters less here than dΓ©cor and vertical climbing surface

Honest disagreement among sources

Group housing

Current best practice: Small, carefully sexed female groups or a single male with multiple females generally do well in a sufficiently sized, well-decorated enclosure

Noted disagreement: Some keepers still default to strictly solitary housing out of general reptile-keeping caution; this species' documented tolerance for conspecifics, genuinely higher than most geckos on this site, makes modest group housing a reasonable, well-supported option rather than a risky exception

Handling

This species is not a good candidate for regular handling, and that's a genuine, species-specific caution rather than boilerplate reptile advice β€” its skin is thin and delicate even by gecko standards, and its tail-drop (autotomy) reflex triggers with less provocation than a leopard gecko's or crested gecko's. A dropped tail regrows but looks visually different afterward, and repeated stress from handling attempts is a real, avoidable welfare cost for an animal this small and this easily startled. This is best appreciated as a low-maintenance display and observation animal β€” genuinely fascinating to watch forage and vocalize at dusk β€” rather than a hands-on pet.

Setting up the enclosure

A 10-gallon enclosure is genuinely adequate for this small species, and vertical space matters more than floor footprint given how much time this gecko spends climbing smooth surfaces β€” multiple pieces of cork bark, driftwood, and secure vertical dΓ©cor let it exercise its climbing adhesive toe pads across essentially every enclosure surface, walls included.

Several tight-fitting hides at different heights and in different microclimates (a cooler, drier spot and a slightly damper one) give this gecko genuine choice, which matters for a species that in the wild shelters in narrow cracks, under bark, and behind human structures like shutters and siding rather than in a single fixed retreat.

A secure, well-fitted lid is essential despite this gecko's small size β€” its climbing ability on smooth glass is excellent, and even a small gap is a real escape risk for an animal this size and this good at scaling vertical surfaces.

Why the lighting and heating numbers matter

The 75-85Β°F ambient range with a modest 88Β°F basking area reflects this species' Mediterranean-basin origin β€” a warm-temperate rather than tropical or desert climate β€” and this gecko doesn't need or benefit from the higher basking temperatures a desert lizard like a uromastyx requires.

Low-level UVB provision is a genuinely evolving area of husbandry practice for this crepuscular-to-nocturnal species, mirroring the same shift seen with other nocturnal geckos on this site β€” some incidental low-intensity UV exposure likely occurs at dusk and dawn in the wild, and there's little downside to a low, correctly shielded dose provided alongside dietary supplementation.

A slightly damp hide, rather than raised overall ambient humidity, supports clean shedding without pushing this drier-climate-adapted species into the higher humidity range a tropical forest gecko would need.

Feeding in practice

This species' small mouth size is the defining constraint on feeding β€” fruit flies work well for hatchlings, and even adults do best on small crickets or roaches rather than anything sized for a larger gecko like a tokay or leopard gecko.

Feeding every 1-2 days for adults, slightly more frequently for growing juveniles, matches this small, fast-metabolism species' actual needs, and uneaten insects should be removed within a day since loose crickets can occasionally nibble at a resting gecko's skin or tail.

Calcium dusting on most feedings, with a D3-inclusive combination worked in weekly, provides the supplementation base this species needs β€” the small quantity of food consumed at each feeding means dusting technique (a light, even coating rather than a heavy dose) matters more here than for a larger reptile that eats bigger portions less often.

Common mistakes with this species

Treating this species like a hands-on pet the way a leopard gecko or crested gecko might be handled is the single most common welfare mistake β€” this gecko's skin and tail are considerably more delicate, and frequent handling attempts produce a chronically stressed animal with an elevated tail-drop risk.

Undersizing prey less often causes problems here than oversizing it does β€” a keeper offering insects sized for a larger gecko species risks a genuine feeding or minor injury problem given this animal's small mouth.

Assuming this species needs desert-level heat or tropical-level humidity, rather than the moderate Mediterranean-climate range it's actually adapted to, is a common setup mismatch that produces a chronically stressed or poorly-shedding gecko.

Lifespan and what to expect

At 5-9 years with correct husbandry, this is one of the shorter-lived reptiles on this site, though still a genuine multi-year commitment for an animal this size and this inexpensive to house.

Growth to adult size happens relatively quickly compared to larger reptiles, and this species reaches sexual maturity within its first year, after which a female housed with a male will produce small clutches of one or two eggs on a recurring basis.

Because this species is so commonly encountered as a wild, naturalized 'house gecko' around porch lights in parts of the southern US, some keepers acquire one informally rather than through the pet trade β€” a wild-caught individual carries meaningfully higher parasite risk and should go through the same quarantine discipline as any other newly acquired reptile before being treated as established.

A female's egg-laying continues on a recurring cycle throughout her adult life once mature, whether or not a male is present, similar to the pattern seen in other reptiles on this site, and a keeper of a female should expect small, regularly recurring clutches rather than a one-time event tied only to active breeding.

Temperament in more depth

This species' temperament is best described as skittish and fast rather than defensive β€” it doesn't bite or display aggressively so much as bolt, and its speed and small size make an escaped Mediterranean house gecko genuinely difficult to recapture in a cluttered room.

Because tail-drop triggers so readily in this species, any necessary handling (for a health check or enclosure transfer) should use a cupped-hands or container-transfer method rather than grasping, and never any contact with the tail specifically.

This gecko's nighttime chirping call, the same vocalization behind its common wild association with porch lights, is normal territorial and social communication rather than a distress signal, and it's one of the more genuinely engaging things about keeping this otherwise low-interaction species β€” many keepers describe simply observing and listening to an active, calling gecko at dusk as the actual appeal of the animal.

Individual temperament does vary somewhat β€” captive-bred, long-established individuals in a stable enclosure often become noticeably less flighty around routine enclosure maintenance over time than a recently wild-caught animal, even without ever becoming genuinely hand-tolerant the way a crested gecko can.

Recommended gear for this taxon

Equipment categories that are genuinely correct for this species' welfare needs β€” see the full Gear Guide for the complete list.

Digital infrared temperature gun

Measures actual basking SURFACE temperature, not just ambient air β€” a stick-on dial thermometer reads air temp, which is a poor proxy for the surface temp that drives digestion and thermoregulation.

Proportional (not on/off) thermostat

Holds a heat source at a stable target temperature rather than the wider swings an on/off thermostat allows β€” meaningfully reduces both overheating and cold-snap risk.

T5 HO UVB tube + reflector fixture

T5 HO output is more consistent across the basking area than compact/coil UVB bulbs, and a reflector fixture roughly doubles usable UVB output from the same bulb β€” match the % output to your species' sourced requirement and replace every 6-12 months regardless of visible light output.
