The common house gecko is very prevalent in Asia. The tropical rainforest, with its humidity varying between 70 and 90%, is its natural habitat, but it has also adapted well to human habitations.
Although native to southern Asia, the species is now pantropical, having been introduced to India, Australia, China, Japan, Africa, South America, Central America and the United States.
A perianthropic species, it is commonly found on the walls of houses in these regions. People are normally happy to see them, as they eat unwanted insects in and around homes.
The common house gecko frequents rainforests, savannahs and deserts. Originally a land animal, it is now seen in trees and on fences and houses, especially if there is light nearby. It is also found under large rocks, decaying logs or on bare ground.
The common house gecko is active when the temperature varies between 19 and 34°C, moving about at night and hiding in nooks and crannies during the day.
