Behavior

The Mediterranean House Gecko is a master of suburban adaptation, often referred to as the 'Moon Lizard' due to its strictly nocturnal lifestyle. Unlike many lizards that flee at the sight of humans, these geckos have learned that human habitations are prime hunting grounds. They are frequently seen upside down on ceilings or clinging to window screens, waiting patiently for insects attracted to the glow of indoor lights.

These lizards are surprisingly vocal, which is a rarity among reptiles. If you are near a colony on a quiet night, you might hear a series of high-pitched squeaks or clicking sounds used to defend territory or attract mates. While they are territorial with other geckos, they are completely harmless to humans and are generally welcomed by homeowners for their role in natural pest control.

Camera Tips

To capture high-quality footage of a Mediterranean House Gecko, focus your camera on vertical surfaces near external light sources. Porch lights, security LEDs, or even glowing windows are 'hotspots' because they attract the moths and insects the geckos prey upon. Position your camera 2 to 4 feet away from the wall to ensure the gecko is large enough in the frame to trigger the motion sensor, as their small size and cold-blooded nature can sometimes fail to trip less sensitive PIR sensors.

Because these geckos are most active in total darkness, IR (infrared) night vision is essential. Most backyard cameras use a 'No-Glow' or 'Low-Glow' IR flash which won't startle the lizard. If your camera allows for macro-focusing or has a close-up lens attachment, use it; these geckos have fascinating skin textures and eye patterns that look incredible in close-up photography. Angle the camera slightly upward to capture them as they traverse the 'vertical horizon' of your home's siding or brickwork.

Sensitivity settings are the most critical factor for this species. Set your camera to its highest motion sensitivity and use 'Burst Mode' or short video clips (10-15 seconds). Since geckos move in a 'dash-and-stop' pattern, a single photo might miss the action, while a video will capture the dramatic moment they lunge for a moth. If you are struggling to get them to appear, try leaving a small light on for an hour before turning it off and letting the camera take over; the lingering insects will keep the geckos active in that specific spot.

During the warmer months, look for 'territory junctions'—corners of walls or areas where two different siding materials meet. Geckos often hide in these crevices during the day and emerge from the same spot every night. Placing your camera near these exits will guarantee a 'money shot' of them emerging for their nightly hunt. In the winter, they may still appear on unusually warm nights, but their movements will be much slower, making them easier to photograph but harder to trigger via motion detection.

Similar Species

Species that look similar or are commonly confused with Mediterranean House Gecko.

Common House Gecko

The Common House Gecko has much smoother skin, lacking the prominent raised bumps (tubercles) found on the Mediterranean variety.

Green Anole

Anoles are diurnal (active during the day), have smooth skin, pointed snouts, and can change color from green to brown.

Tropical House Gecko

Very similar but usually larger with more distinct dark bands on the tail and a slightly different arrangement of scales on the underside of the toes.

Frequently Asked Questions

Mediterranean House Geckos are strictly nocturnal. They typically emerge shortly after sunset and reach their peak activity levels between 9:00 PM and 2:00 AM, when insect activity around artificial lights is highest.

The best way to attract them is to provide a food source by keeping outdoor porch lights on. These lights attract moths and other insects, which in turn attract the geckos. Providing small crevices or 'gecko houses' made of stacked PVC pipes or wood can also provide them with daytime hiding spots.

They are insectivores that eat almost any small invertebrate they can catch, including moths, spiders, small cockroaches, crickets, and beetles. They are famous for 'sit-and-wait' predation near light fixtures.

Yes, they are highly common in suburban and urban areas throughout the Southern and Southeastern United States. They have adapted specifically to live on human structures like brick walls, warehouses, and houses.

Look for their distinct bumpy skin (tubercles) and large, lidless eyes with vertical pupils. Unlike the smooth-skinned Green Anole, the Mediterranean House Gecko has a translucent appearance and specialized toe pads that allow it to walk easily across glass and ceilings.
