Species overview
About the Common House Gecko
The common house gecko is usually pale gray, beige or brownish. Broad toe pads help it grip walls, while its large eyes suit life in dim light. It may wait near outdoor lights where insects gather.
This species is introduced in Costa Rica. Familiar does not always mean native. Watch without catching it, and do not transport geckos, their eggs or hiding materials to other places. Comparing a wall gecko with a native forest gecko can open a useful conversation about how people change the places where animals live.
