Hemidactylus frenatus or the Asian house Gecko or simply, the house lizard. They can be seen climbing walls of houses and other buildings in search of insects attracted to porch lights, hence their name. Spread around the world by ships, these geckos are now common in the southern half of the United States, large parts of tropical and sub-tropical Australia, and many other countries in South and Central America, Africa, Asia, and the Middle East. They grow to a length of between three to six inches (about 7.5–15 cm), and live for about five years.
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. The animal is very adaptable and may prey on insects and spiders, displacing other reptiles.
Like many geckos, this species can lose its tail when alarmed. Its call or chirp rather resembles the sound “gecko, gecko”. However, this is an interpretation, and the sound may also be described as “tchak tchak tchak” (often sounded three times in sequence).
