Known as the Pacific house gecko, the Asian house gecko, or simply, the house lizard, it is the most recently discovered member of a quartet of small, prolific and aggressive lizards (or Gekkonids) that are nocturnal. 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 as well as large parts of Australia. 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.
