Common house gecko
The common house gecko (Hemidactylus frenatus), also known as the Asian house gecko, is a small, nocturnal lizard native to South and Southeast Asia and Near Oceania. Easily recognizable by its chirping vocalizations, it thrives in warm, humid environments, particularly within urban landscapes where it forages for insects attracted to artificial lights. This adaptable species has a wide distribution and can be found on walls of buildings and in various natural habitats.

About Common house gecko
The common house gecko, scientifically known as Hemidactylus frenatus, is a widespread gecko species native to South and Southeast Asia and Near Oceania. It is also recognized by several other common names, including the Asian house gecko, Pacific house gecko, and wall gecko. This small to medium-sized reptile is easily identified by its characteristic chirping vocalizations, which have inspired various cultural beliefs and superstitions in different regions.
Habitat and Distribution
This species demonstrates a strong preference for warm, humid environments and has become highly successful in urban landscapes. Common house geckos are frequently found on the walls of houses and other buildings, where they forage for insects attracted to artificial lights. While they can inhabit bushland and woodlands, their distribution is largely defined by proximity to urban areas. Their adaptability has led to introductions across the globe, including parts of the Americas, Australia, and various islands.
Diet and Behavior
The common house gecko is primarily nocturnal, emerging at night to hunt for its prey. Its diet consists mainly of invertebrates such as cockroaches, termites, moths, flies, and spiders, but they are also known to consume mollusks and smaller geckos. They are non-venomous and generally pose no threat to humans, though they may bite if handled or distressed. Males can exhibit territorial behavior, with some displaying larger head sizes, suggesting a selective pressure favoring biting force.
Reproduction and Biology
Common house geckos are oviparous, with females typically laying a maximum of two hard-shelled eggs at a time, though up to four eggs can be in various stages of development in their ovaries. Males have mature sperm year-round, which can be stored by females for extended periods, facilitating reproduction in new habitats. The species exhibits a range of thermoregulatory behaviors, seeking out warmer or cooler spots to maintain bodily temperature. While largely nocturnal, they also display activity during the day for thermoregulation. Their physiological adaptations are geared towards tropical and subtropical conditions, which may limit their presence in arid environments.

Where does the common house gecko live?
This species is native to South and Southeast Asia and Near Oceania. It has also been introduced to many other regions around the world, including parts of the United States, Australia, Mexico, and various islands in the Caribbean, often establishing itself in urban areas.
What do common house geckos eat?
The diet of the common house gecko primarily consists of invertebrates, which they hunt around urban structures. This includes insects like cockroaches, termites, moths, and flies, as well as spiders, mollusks, and even smaller geckos.
Are common house geckos dangerous to humans?
No, common house geckos are non-venomous and not harmful to humans. While they may bite if distressed, these bites are generally not capable of piercing skin and are not venomous.
What are the distinctive sounds made by common house geckos?
Common house geckos are immediately recognizable by their characteristic chirping sounds. In some cultures, these chirps are associated with various omens or predictions.
What is the typical size and lifespan of a common house gecko?
Common house geckos grow to a length of between 7.5 to 15 cm (3 to 6 inches). Their typical lifespan is around 7 years.
Why are common house geckos considered an invasive species in some areas?
In certain regions, common house geckos have negatively impacted native gecko populations through exclusionary behavior and competition for resources. Their adaptability, aggressive territoriality in males, and ability to thrive in urban environments contribute to their invasive success.

Hemidactylus frenatus
Hemidactylus frenatus, commonly known as the common house gecko, is a nocturnal lizard native to South and Southeast Asia and Near Oceania. These adaptable geckos are easily recognizable by their chirping sounds and are often found in urban environments, climbing walls of buildings to hunt insects attracted to lights. They are non-venomous and generally docile but can bite if threatened.
Sphenops sepsoides
Sphenops sepsoides, also known as the wedge-snouted skink, is a common and widespread skink species found across North Africa and the Middle East. This viviparous lizard is a sand specialist, adept at 'swimming' beneath the sand with its reduced limbs, rarely emerging onto the surface. It inhabits sandy areas and dunes, exhibiting nocturnal behavior in summer and diurnal activity in winter.
Hemidactylus mabouia
The tropical house gecko (Hemidactylus mabouia) is a small lizard native to sub-Saharan Africa, now widespread in the Americas and Caribbean due to human introduction. Characterized by its ability to change color based on temperature and light, it possesses specialized toe lamellae for climbing vertical surfaces. This nocturnal hunter primarily inhabits urban environments, preying on a variety of insects and small invertebrates.
