The common house gecko (Hemidactylus frenatus) (not to be confused with the Mediterranean species Hemidactylus turcicus known as Mediterranean house gecko), is a gecko native of Southeast Asia. It is also known as the Pacific house gecko, the Asian house gecko, wall gecko, house lizard, or moon lizard.

Most geckos are nocturnal, hiding during the day and foraging for insects at night. They can be seen climbing walls of houses and other buildings in search of insects attracted to porch lights and is immediately recognisable by its characteristic chirp.

They grow to a length of between 75–150 mm (3–6 in), and live for about 5 years. These small geckos are non-venomous and not harmful to humans. Medium to large geckos may bite if distressed; however, their bite is gentle and will not pierce skin. A tropical gecko, Hemidactylus frenatus thrives in warm, humid areas where it can crawl around on rotting wood in search of the insects it eats, as well as within urban landscapes. The animal is very adaptable and may prey on insects and spiders, displacing other gecko species which are less robust.
