Hemidactylus turcicus, commonly known as the Mediterranean house gecko, is native to the Mediterranean region. Its geographical distribution includes Southern Europe (Portugal, Spain, Italy, Greece), Northern Africa (Egypt, Libya, Tunisia), and parts of Western Asia (Turkey, Cyprus, Israel).

The Mediterranean house gecko typically inhabits warm, temperate environments characterized by dry summers and wet winters. It is often found in rocky habitats, open woodlands, and urban areas where it can exploit human-made structures.

This species is primarily nocturnal and insectivorous, preying on small insects and arthropods. It is well-adapted to human environments, frequently found on and in buildings, taking advantage of artificial lighting to hunt for insects. In its native range, it occupies a versatile ecological niche allowing it to thrive in both wild and urbanized landscapes.
