Mediterranean House Gecko

Explore all 4 supporting guides ↓

The Mediterranean house gecko is a small, pale lizard that clings to walls near porch lights. It waits there for insects drawn to the glow. Adults rarely pass five inches from nose to tail.

The species is native to the Mediterranean basin. It has ridden cargo and nursery plants across the globe. It now lives on buildings from Texas to Buenos Aires.

Herpetologists know this animal as Hemidactylus turcicus. Everyone else uses a shorter list of names. Mediterranean gecko, Turkish gecko, or just med gecko among keepers.

The Turkish gecko name comes from Turkey. That country sits well inside the species’ native range. The name stuck long before the gecko spread worldwide.

That native range covers Portugal, Spain, southern France, Italy, Greece and its islands, and Turkey. It continues through North Africa from Morocco to Egypt. From there it crosses the Middle East into Pakistan and parts of India.

The species has since spread through the pet trade, nursery stock, and shipping crates. It now lives in the southern United States, Mexico, Cuba, Puerto Rico, and Bermuda. It also turns up in Panama, Argentina, and parts of England around heated buildings.

The spread continues. Herpetologists were already recording range extensions along the northeastern Gulf Coast by 1993. A 2014 survey in the Journal of North American Herpetology found the species in 17 of 21 northern Louisiana parishes, nearly always on buildings.

In most of its introduced range, the Mediterranean house gecko is not a pet at all. It is a feral, self sustaining population. It shows up on stucco walls and under porch eaves every summer night.

Keepers who want one usually catch a local gecko rather than buy one. The species is rarely bred or sold commercially. Most captive individuals started out wild.

Color runs pale pink to grayish tan by day. It can shift lighter or darker with temperature and mood. Many geckos share this trait.

The skin looks slightly translucent. Small bumpy tubercles run down the back. Large lidless eyes give it strong night vision.

Toe pads let it grip smooth vertical surfaces with ease. Glass and painted stucco pose no problem. That grip is part of why it thrives on human buildings.

Mediterranean House Gecko Care

Mediterranean house gecko care is simple compared to many popular pet lizards. The species is small, hardy, and already adapted to life around people. A single adult does well in a modest, secure terrarium with climbing surfaces, a temperature gradient, and small insects on a regular schedule.

The main challenge is keeping the enclosure escape proof. This gecko is a strong climber and can squeeze through tiny gaps. The second challenge is offering prey small enough for its narrow jaws.

Most captive individuals are wild caught rather than captive bred. A new keeper should expect a shy, fast moving animal at first. Calm, regular feeding sessions help it settle over time.

Handling should stay rare and brief. This species is delicate and stresses easily. It is better suited to watching than to daily handling.

Enclosure Setup for a Mediterranean House Gecko

A single adult does well in a terrarium of at least 10 gallons. More floor space and especially more height count as a bonus. This gecko spends most of its time vertical, so tank height matters more than floor space.

Use bark, cork rounds, or textured backgrounds for climbing. A tightly fitted, well ventilated lid is essential. This species can squeeze through surprisingly small gaps.

Substrate can be a simple mix of coconut fiber and sand. Keep it mostly dry with one slightly damper corner. Add cork bark, driftwood, and a few plants for cover.

Multiple hides at different heights help the gecko pick its preferred temperature. This reduces stress and encourages natural behavior. A gecko with choices settles in faster.

A shallow water dish helps, though this species often prefers droplets. It licks moisture off misted glass and leaves. Light nightly misting keeps humidity comfortable without soaking the tank.

Heating and Lighting

This species comes from a hot, dry to semi arid climate. Daytime basking areas should reach roughly 85 to 90°F (29 to 32°C). The cooler end should sit around 75 to 80°F (24 to 27°C).

Nighttime temperatures can drop into the upper 60s or low 70s Fahrenheit. This mirrors the cool nights typical of Mediterranean summers. No extra heat is needed after dark in most homes.

Humidity should stay moderate, generally 40 to 60 percent. That is higher than a true desert setup but far short of a rainforest tank. A digital thermometer and hygrometer give a far more accurate read than adhesive strips.

This species is nocturnal, so it does not bask under direct light like a daytime gecko. A low level UVB bulb, such as the Arcadia ProT5 Kit Forest 6%, on a daytime cycle still supports vitamin D and normal activity. Pair it with about 12 hours of light and 12 of dark, and avoid bright light around the clock.

What Mediterranean House Geckos Eat

In the wild, this species hunts insects, pillbugs, spiders, and other small arthropods. It takes whatever fits its mouth and moves within reach. Juveniles target tiny prey such as leafhoppers, while adults tackle small grasshoppers and caterpillars.

In captivity, a rotating diet works best. Offer appropriately sized crickets and small dubia roaches for adults. Use fruit flies for juveniles that cannot yet manage larger prey.

Feed insects no wider than the gap between the gecko’s eyes. This is a small species with a small mouth. Oversized prey can injure it or simply get ignored.

Dust prey with a calcium supplement, such as the Zoo Med Repti Calcium without D3, at most feedings. Add a general reptile multivitamin once or twice a week. This is typical practice for small insectivorous geckos.

Offer food two to three times a week for adults. Growing juveniles need slightly more frequent meals. Remove uneaten live insects so they cannot nip a resting gecko overnight, a routine covered in our Mediterranean house gecko diet guide.

Health and Common Problems

Mediterranean house geckos are generally hardy. Like all small geckos, they can develop metabolic bone disease from poor calcium or UVB. A cold, damp enclosure can also bring on respiratory infections.

Watch for stuck shed around the toes and tail tip. This usually points to low humidity during a shed cycle. A quick, gentle mist often solves it.

Other warning signs include lethargy, a swollen or soft jaw, and labored breathing. Retained skin over the eyes is another red flag. Any of these calls for a closer look.

This species drops its tail readily as a predator defense. Expect occasional tail loss from rough handling or a startled grab. The tail regrows, usually shorter and less patterned, and this on its own is not an emergency.

See a reptile veterinarian if a gecko stops eating for more than a couple weeks. The same goes for noticeable weight loss or discharge from the eyes or mouth. Early care matters more in an animal this small, since dehydration progresses fast.

Behavior and Temperament

This is a nocturnal, insect hunting gecko. It spends daylight hours tucked into a crack, under bark, or behind a picture frame. It emerges after dark to forage.

In the wild, it is famous for gathering near porch and street lights. It picks off moths and other insects drawn to the glow. This habit is why so many people first meet the species by accident.

Mediterranean house geckos are territorial toward each other. They can behave aggressively if housed together, especially two males in a small space. They communicate with soft clicks and squeaks, a trait shared with several other Hemidactylus geckos.

Toward keepers, this species tends to be flighty and quick. Most individuals settle into a predictable feeding routine. Few ever become geckos that enjoy handling.

This suits a keeper who wants an animal to watch rather than hold. It is a poor match for anyone hoping for a tame lizard. Its charm is in its speed and its wild behavior.

Breeding

Mediterranean house geckos breed seasonally, generally from spring through late summer. This lines up with warmer temperatures and longer days. A female typically lays a small clutch of two hard shelled eggs at a time.

She can produce several clutches across a single breeding season. Eggs are often glued to a hidden surface, a crack, or the underside of bark. This anchors them safely away from most predators.

Eggs take roughly 40 days to hatch near 88°F (31°C), based on field studies. Hatchlings are fully independent the moment they emerge. They receive no parental care at all.

Sexual maturity arrives fast for such a small lizard. Females can mature in as little as four to five months, though around 18 months is more typical. Males average about a year.

This quick turnaround is part of why the species establishes so readily. A few founding geckos can seed a whole neighborhood population within a couple of years. That speed explains its wide introduced range today.

Lifespan and Size

A Mediterranean house gecko reaches roughly 4 to 5 inches (10 to 13 cm) as an adult. A few individuals reach about 6 inches (15 cm). It remains one of the smaller geckos a keeper is likely to encounter.

Males and females stay close in size. Animal Diversity Web lists males as slightly larger. The difference is small enough that size alone will not reliably sex a gecko.

Lifespan in captivity runs up to about 8 years with attentive care. Field studies of wild Turkish populations found adults living 4 to 9 years, with none recorded past 9. Wild and captive figures line up closely for this species.

Cost of Keeping a Mediterranean House Gecko

This species is rarely bred commercially. It is instead an established feral population across much of the southern United States. It is not sold the way popular pet geckos, like the leopard gecko or crested gecko, are sold.

Most keepers who own one either caught it locally, where legal, or got it informally from another keeper. Few buy one from a store. This keeps the direct acquisition cost close to zero for most owners.

Setup costs matter more than acquisition cost here. A basic terrarium, heating, low level UVB lighting, a thermometer and hygrometer, and furnishings add up to a typical small gecko starter budget. Ongoing costs cover feeder insects and supplements, similar to what a keeper of a gargoyle gecko or mourning gecko would expect to spend.

Because the species is already widespread and treated as a pest in many areas, rules vary by state and country. Confirm local regulations before collecting or keeping a wild gecko. Some regions restrict possession of invasive wildlife even when the animal is common.

For readers comparing geckos before choosing one to keep, the Mediterranean house gecko sits at the opposite end of the hobby from showpiece species like the tokay gecko or gold dust day gecko. It rewards patience and observation rather than handling. Details on general enclosure planning live in the housing guide, and broader feeding guidance sits in the feeding guide.

Anyone unsure a small, skittish gecko fits their goals should also read the wider geckos overview, or check the health guide before bringing one home.

Frequently Asked Questions

Is a Mediterranean house gecko a good pet?

It can work well for a keeper who wants a small, low maintenance, nocturnal gecko to observe rather than handle. It is not the best choice for someone who wants a tame, interactive lizard.

Are Mediterranean house geckos invasive?

Yes, in much of the southern United States and several other regions outside their native Mediterranean range. These geckos live as an established, self sustaining feral population rather than a controlled captive species.

What is the difference between a Mediterranean gecko and a Turkish gecko?

They are the same animal. Mediterranean gecko, Turkish gecko, and med gecko are all common names for Hemidactylus turcicus.

How big does a Mediterranean house gecko get?

Most adults reach about 4 to 5 inches (10 to 13 cm) in total length. A maximum around 6 inches (15 cm) has been reported for the species.

What do Mediterranean house geckos eat in captivity?

Appropriately sized crickets, small roaches, and fruit flies for juveniles cover the basic diet. Dust prey with calcium and offer it a few times a week.

How long do Mediterranean house geckos live?

Captive lifespan runs up to about 8 years. That closely matches lifespans recorded in wild populations studied in the field.
