Description

This species can attain a maximum length, from snout to vent, of 12.7 cm (5 in). Being nocturnal, it has very large eyes which are useful in spotting prey in low light conditions. It can change color (slowly) from light brown to a darker brown to better match its surroundings.

Human impact

In some Caribbean cultures it is considered good luck to have a tropical house gecko residing in one's home, and certainly they do eat a lot of household insect pests. However, the feces of the tropical house gecko are approximately long, wide, and dark brown (almost black) in color. The gecko will usually confine its feces to one area of a home, but if that area happens to be a pale-colored carpet, drapes, or any other easily stained surface, the stains are not easily removed, and the droppings have to be physically scooped up as well. Despite being harmless, the common house gecko or 'woodslave' is considered by some in Trinidad & Tobago to be a bad omen and to have a poisonous touch. This is an old superstition and, in actuality, the house gecko is harmless and very useful due to hunting spiders and cockroaches.
