This study examined the diversity and distribution of gecko species within the newly constructed Danjuma Hostel, University of Benin (UNIBEN), Ugbowo Campus, Edo State, Nigeria. The survey was conducted from August to October 2025 to determine how quickly Hemidactylus species establish in modern human dwellings. Visual encounter surveys were carried out during both day and night, focusing on walls, ceilings, corridors, and nearby vegetation. A total of 18 geckos were recorded, comprising Hemidactylus mabouia (10 individuals, 55.6%) and Hemidactylus angulatus (8 individuals, 44.4%). Despite the hostel’s recent construction, both species displayed remarkable adaptability, indicating early colonization facilitated by artificial lighting, insect availability, and microhabitat conditions. H. mabouia was predominantly observed in light-exposed areas, while H. angulatus occupied more secluded and shaded sections, suggesting niche differentiation within a shared environment. These findings reveal that ecological succession in human structures can occur much faster than previously assumed, particularly among synanthropic reptiles. The presence of both species in near-equal proportions implies a balanced micro-ecosystem, where competition and resource partitioning allow coexistence. Beyond its local significance, this study underscores the broader ecological principle that nature wastes no opportunity to reclaim and inhabit newly available niches, even those fashioned by human hands
