Common house gecko

The common house gecko (Hemidactylus frenatus) is a small, nocturnal gecko native to South and Southeast Asia. It has spread to warm regions worldwide, where it often lives on buildings.

Gecko feet: Gecko feet use microscopic structures on their toes to adhere to many surfaces without liquid glue. Its toe pads let it climb walls and ceilings while hunting around buildings.
South Asia: South Asia is a region of Asia that includes the Indian subcontinent and neighboring countries. The gecko's native range includes parts of this region.
Biological pest control: Biological pest control uses living organisms to suppress populations of pests. By eating insects, the gecko can reduce some insect activity around buildings.
Common house gecko in Florida: The common house gecko is an introduced species established in parts of Florida. Florida illustrates its establishment in a warm region outside its native range.
Setae: Setae are microscopic, hairlike structures that cover the adhesive surfaces of gecko toes. These structures create the close contact that lets the gecko cling to smooth surfaces.
Southeast Asia: Southeast Asia is the region between the Indian subcontinent, China, and Australia. The species is native to parts of this region as well as South Asia.
Insect light trap: An insect light trap attracts flying insects with light and captures or kills them. Lights concentrate prey that the gecko hunts on nearby walls.
Common house gecko in Australia: The common house gecko is an introduced gecko established in parts of Australia. Australian populations show how it occupies buildings beyond its Asian homeland.
Van der Waals force: Van der Waals forces are weak attractions between atoms and molecules that act at very short distances. They contribute to adhesion between gecko toe structures and surfaces.
Biological invasion: A biological invasion occurs when a species establishes and spreads beyond its native range. Human transport and settlement have helped this gecko establish populations worldwide.
