Olive House Snake

Fascinating facts about the Olive House Snake

• Elaiophis inornatus commonly reaches a total length of 45–75 cm, with a recorded maximum of 130 cm.
• When night falls along South Africa’s eastern coast, it hunts lizards, tiny rodents and other snakes from the ground; it is nocturnal and generally terrestrial.
• It may bite when molested and is preyed upon by raptors such as the snake eagle and the secretary bird, as well as by other snakes.
• Found from the southwestern Cape up to Limpopo, this snake tolerates coastal bushveld, fynbos and even gardens near human homes, but no confirmed records exist from Namibia. Its presence near people underscores how wildlife can adapt to, and coexist with, urban fringes.

About the Olive House Snake

Elaiophis inornatus, the olive house snake, is a sleek, non-venomous lamprophiid that typically measures 45–75 cm, though some individuals have been recorded at a striking 130 cm. Its coloration ranges from dark olive to deep black, while lighter forms display a uniform light brown to olive-grey-green hue, often with a slightly paler belly and a subtly lighter chin, throat, and neck. This modest size and muted palette allow the snake to blend seamlessly into the moist coastal bushveld, fynbos, and grassveld of South Africa and Eswatini, where it frequents low-veld regions from the southwestern Cape through East London to the Transkei, and extends into the KwaZulu-Natal escarpment, Mpumalanga, and Limpopo Province. Nocturnal and primarily terrestrial, the olive house snake prowls the ground under the cover of night, moving slowly and displaying a docile temperament unless provoked. Its diet is opportunistic, comprising lizards, small rodents, and even other snakes, while females lay clutches of five to fifteen eggs. A surprising trait for a modest snake is its role as both predator and prey: raptors such as the snake eagle and secretary bird, as well as larger snakes, regularly hunt it, weaving the olive house snake into a dynamic nocturnal food web that pulses through southern Africa’s moist habitats.
