Mediterranean House Gecko: Care, Lifespan, Diet & Size

Mediterranean house geckos are one of the most underrated beginner reptiles available. They’re small, hardy, genuinely easy to care for, and have a personality that makes them surprisingly engaging to watch. I’ve seen new keepers thrive with these geckos where they might have struggled with a more demanding species, and that’s exactly why I recommend them so readily. This guide covers everything you need to get their care right from day one.

Quick Care Reference

Species Summary

The Mediterranean house gecko (Hemidactylus turcicus) is a unique reptile that entered the pet trade by unconventional means. Native to the Mediterranean basin — most prevalent in countries like Cyprus, Turkey, and Spain — this lizard is so widespread in its home range that it’s genuinely considered a household fixture. Many cultures regard harming them as taboo, partly due to their gentle nature and their value as natural insect controllers.

In 1915, Mediterranean house geckos appeared in Florida — almost certainly introduced as escaped or released pets. Their adaptability allowed them to establish thriving populations in Florida, Texas, and neighbouring warm states, where they are now considered an invasive species. If you live in Florida or the Gulf Coast states, you’ve almost certainly seen them on walls and ceilings at night. That same adaptability makes them one of the most straightforward gecko species to keep in captivity.

Appearance and Colours

Mediterranean house geckos are easy to identify among types of geckos. The body is typically grey, brown, or tan with pink and purple undertones, bumpy skin texture, and darker mottled spots. The tail features bands rather than spots, creating a distinct pattern from the body. The underbelly is white and translucent enough that you can sometimes see the heart beating or developing eggs through the skin.

The head is wide with a rounded snout. Eyes are large, lidless, and feature vertical slit pupils — characteristic of nocturnal hunters. Like all geckos, they have short stocky limbs with dexterous fingers and adhesive toe pads that allow them to climb smooth vertical surfaces with ease.

Can You Keep Them as Pets?

Yes — Mediterranean house geckos make excellent pet lizards, particularly for beginners. They’re easy to care for, peaceful, and their small size makes them suitable for most living situations. If you live in Florida or a Gulf Coast state where these geckos are common in the wild, the temptation to catch one is understandable — but resist it. Wild-caught geckos carry higher parasite loads, have unknown ages and health histories, and are significantly more stressed by captivity than animals raised in it from birth.

Where to buy: Look for a captive-bred animal from a specialist reptile breeder or a reputable exotic pet store. Mediterranean house geckos are widely available and generally inexpensive — expect to pay $10 to $30 for a healthy captive-bred gecko. Prices above that range without a clear reason (unusual colouration, proven lineage) should be questioned.

What to look for in a healthy gecko: When selecting your animal, look for clear, alert eyes, all toes intact and free of retained shed, a plump tail base (indicates good body condition), and active movement when gently disturbed. Avoid animals that appear lethargic during their active hours, have sunken eyes, visible ribs, or any discharge around the nose or mouth. In my experience, spending an extra few minutes assessing the animal at purchase saves a lot of heartache and vet bills down the line.

Mediterranean House Gecko Lifespan

The average Mediterranean house gecko lifespan in captivity ranges from 3 to 9 years. That’s a wide range, and care quality is the biggest variable. Geckos kept in stable, clean enclosures with appropriate temperatures, humidity, and a nutritious varied diet consistently live toward the upper end of that range. Wild-caught animals or those kept in suboptimal conditions typically live shorter lives regardless of how well they’re cared for after acquisition.

Expert Tip: Buying captive-bred from a reputable breeder is the single most impactful decision you can make for lifespan. Wild-caught geckos often arrive with parasite loads, stress-related health issues, and unknown ages — all of which shorten their lives in captivity regardless of how good their ongoing care is.

Average Size

Full-grown Mediterranean house geckos reach 4 to 5 inches in length. Occasionally a large specimen will slightly exceed 5 inches, but they never get significantly bigger than that. Their small size is one of their appeals — they don’t require large enclosures, they’re easy to handle, and they’re much less intimidating for new keepers than larger gecko species like the tokay gecko or leachianus gecko.

Mediterranean House Gecko Care

A species resilient enough to establish invasive populations on a different continent is more than capable of thriving in captivity. Mediterranean house gecko care is genuinely beginner-friendly — get the basics right and these little geckos will take care of themselves.

Enclosure Size

A 10-gallon glass aquarium is the minimum for a single adult. Hatchlings can start in a 5-gallon tank. For the optimal setup, a 20-gallon vertically-oriented terrarium is the best choice — these geckos are climbers and the extra vertical height gives them the wall space and enrichment they use constantly.

Expert Tip: For groups, a 20-gallon is the minimum for three geckos — add approximately 5 gallons per additional animal. Always secure a metal mesh lid — these geckos are escape artists and will find any gap in a loose-fitting cover.

What To Put In Their Habitat

Mediterranean house geckos are adaptable and do well in a range of setups. The goal is to create a habitat with plenty of climbing surfaces, adequate hiding spots, and appropriate moisture retention in the substrate.

For substrate, paper towels are the most practical option — easy to replace, impossible to accidentally ingest, and makes monitoring droppings for health changes straightforward. Reptile carpet works but requires frequent cleaning. For a more naturalistic setup, additive-free cypress mulch, orchid bark, or organic topsoil all work well and help maintain humidity. Adding sphagnum moss or leaf litter completes the look and gives your gecko additional hiding cover.

Expert Tip: Whatever substrate you use, avoid loose particulate that could cause impaction if ingested during feeding. This is particularly important for juveniles, who are more likely to accidentally swallow substrate while striking at insects.

Add cork bark, branches, vines, and dense foliage — real or artificial — to create multiple climbing routes and hiding spots. Mediterranean house geckos spend most of their daytime hours tucked away in hides, so having several options at different heights gives them the security they need to stay settled and stress-free. See our guide on reptile thermostat options to keep temperatures consistent without manual adjustment.

Temperature and Lighting

Mediterranean house geckos need a temperature gradient to thermoregulate effectively:

• Ambient temperature: 75°F (24°C)
• Basking spot: 90°F (32°C) — on one side of the enclosure
• Night minimum: 65°F (18°C) — don’t let it drop below this

Use a combination of incandescent or halogen basking bulb and a heating pad to achieve these gradients. Always run heat sources through a quality thermostat — this prevents temperature spikes and reduces electricity use.

Expert Tip: This species is largely nocturnal so full-spectrum UVB lighting is not required. That said, a low-output UVB tube does help maintain a natural day/night cycle and won’t cause harm. If you choose to use one, run it on a timer for 10–12 hours daily and switch it off completely at night.

Humidity

Keep humidity between 60 and 75 percent. A hygrometer is essential — guessing at humidity levels leads to chronic respiratory issues or skin problems that develop slowly and are easy to miss until they’re serious. Mist the enclosure once or twice daily to maintain levels; the substrate and plants will hold moisture between sessions. If humidity runs too high, increase ventilation by using a mesh-top enclosure or partially uncovering the lid.

Water

Include a shallow water dish large enough for the gecko to soak in. Mediterranean house geckos primarily drink by lapping water droplets from misted surfaces rather than from a bowl — which is another reason why daily misting is important. Refresh the water dish every 2–3 days and disinfect it weekly.

Mediterranean House Gecko Food and Diet

Mediterranean house geckos are true insectivores. Their diet consists entirely of live insects — they typically won’t touch plant-based foods at all. In the wild they eat moths, cockroaches, small beetles, and whatever else they can catch. In captivity, rotate between crickets, dubia roaches, mealworms, and waxworms to provide nutritional variety.

Always gut-load feeder insects for 24–48 hours before offering them — the nutritional content of the insect directly affects your gecko’s health. Never offer insects larger than the width of the gecko’s head to prevent choking and impaction. Feed 4–5 insects per session, 3–4 times per week.

Expert Tip: Dust feeder insects with a calcium and vitamin D3 supplement at every other feeding. Without supplementation, even a varied insect diet will leave your gecko deficient over time — calcium deficiency is one of the most common and most preventable health issues in captive insectivores.

Potential Health Issues

Mediterranean house geckos are hardy animals — their invasive success in multiple countries on two continents is a testament to that. With appropriate husbandry they rarely get sick. The conditions to watch for are almost all caused by environmental problems rather than bad luck:

• Respiratory infections — caused by incorrect temperature or humidity. Signs include laboured breathing, mucus around the nostrils, and inflamed mouth tissue. Requires veterinary antibiotics. Prevent by keeping enclosure parameters stable
• Skin infections and fungal issues — caused by unsanitary conditions. Spot clean daily, do a full disinfection monthly using reptile-safe cleaner or a 10% bleach solution. Healthy droppings are long, light brown with a white tip — runny or crumbly poop indicates a problem
• Impaction — occurs when a gecko ingests too much loose substrate while hunting. Signs include loss of appetite, lethargy, and visible abdominal swelling. Preventable by using non-loose substrate, particularly for juveniles. Contact a reptile-experienced vet if impaction is suspected

Behaviour and Temperament

Mediterranean house geckos are gentle, relaxed animals that rarely show aggression. They spend their days hidden in hides and become most active after dark — you’ll see the most behaviour in the hours around midnight. Geckos can bite when threatened or mishandled, but Mediterranean house geckos are among the least likely gecko species to do so once settled.

Expert Tip: Don’t judge your gecko’s health or behaviour based on daytime observations. These are nocturnal animals and will spend most daylight hours tucked into a hide looking completely inactive. Check on them in the evening when their natural activity window begins.

Vocalisation — one of the more surprising things about Mediterranean house geckos is that they’re vocal. They produce chirping and squeaking sounds, particularly during territorial disputes and when startled or threatened. If you hear a rapid series of clicks or high-pitched squeaks from the enclosure, it usually means one gecko is warning off another. A single gecko that chirps at you during handling is expressing mild discomfort — put it back and try again later. The sound takes new owners by surprise every time but is completely normal.

Wall climbing — Mediterranean house geckos are exceptional climbers and will use every surface available to them. Their adhesive toe pads work via van der Waals forces — millions of microscopic hair-like structures called setae that create intermolecular attraction between the pad and the surface. This is why they can walk upside down on glass with ease and why a mesh lid is non-negotiable — they will find the ceiling of their enclosure and test every corner for gaps. Watching them navigate vertical surfaces at speed is genuinely one of the most entertaining things about keeping this species.

Mediterranean house geckos can be kept in groups, but planning the composition carefully matters. Males are territorial and will fight, often resulting in tail drops. The safest group configuration is one male with multiple females. Even with a single-sex group, ensure the enclosure is large enough that each gecko can establish its own territory without constant conflict. A squeaking call is a territorial warning — persistent squeaking in a group enclosure means someone is being stressed and the group composition or enclosure size may need to change.

Handling

Mediterranean house geckos tolerate handling well once trust is established, but they move fast and require a calm, confident approach. A nervous, tentative hand actually makes things worse — geckos read hesitation as a threat. Slow, deliberate movements are far more reassuring than quick grabs.

Taming a new gecko — step by step:

1. Leave it alone for the first week. A new gecko needs time to settle and establish that the enclosure is safe. Handling too early sets taming back significantly
2. Start with hand presence. Rest your hand inside the enclosure without trying to pick it up. Let the gecko investigate on its own terms — it will lick your hand and approach when it’s ready
3. Short sessions first. Once the gecko approaches calmly, gently scoop from below rather than grabbing from above. Keep initial sessions to 2–3 minutes and end before the gecko shows stress signals
4. Build duration gradually. Over several weeks, increase session length as confidence grows. A well-handled Mediterranean house gecko will eventually crawl onto your hand voluntarily

Support the body fully at all times and never grip the tail. Tail drop is easily triggered by any sensation of being grabbed around the tail — the gecko releases it as a predator distraction mechanism. The tail regenerates, but it grows back as cartilage rather than bone and never looks quite the same. I always handle these geckos over a low surface or close to the ground for the first few sessions — they’re fast, and a short drop is far better than a long one if they bolt unexpectedly.

If your gecko shows discomfort — rapid movement, chirping, or attempting to hide in your hands — return it to the enclosure immediately. End on a calm note rather than persisting through stress. Consistent, patient handling over several weeks produces a gecko that’s genuinely comfortable. Rushing the process produces the opposite. Always wash hands before handling to remove any food scent, and wash after. See our lizard names guide if you’re still deciding what to call your new gecko.
