common house gecko

a common gecko found climbing on the wall;
They can be seen climbing walls of houses and other buildings in search of insects attracted to porch lights, hence their name.
They grow to a length of between three to six inches (about 7.5–15 cm), and live for about five years.
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).
