Key identifying features
The Olive House Snake is identified primarily by its uniform olive-brown to olive-green body coloration, generally lacking strong blotches, bands, or stripes, giving it a relatively plain but distinctively toned appearance. Its smooth, glossy scales and slender build are consistent with other house snakes, but the olive cast to its coloring helps separate it from browner or grayer relatives.
Coloration & pattern
The body is typically a consistent olive-brown, olive-gray, or olive-green, sometimes with very faint darker speckling that is easily overlooked at a distance. Unlike species with a distinct stripe or blotch pattern, the Olive House Snake usually appears almost uniformly colored along its length. The belly is pale, often cream, yellow, or light gray.
Head, eyes & scales
The head is small and rounded, not triangular, blending smoothly into the neck. Eyes are moderate in size with round pupils. Scales are smooth and glossy, giving the body a sleek, polished look, particularly evident in fresh-shed individuals.
Size & body shape
Adults typically measure 24 to 36 inches, with a slender, lightly built body and a tail tapering to a fine point. The build favors flexibility and speed for maneuvering through crevices and tight spaces rather than bulk.
Range & habitat where you'll see it
Olive House Snakes are found across parts of southern and eastern Africa, inhabiting grassland, savanna, rocky hillsides, and areas around human habitation, including gardens, farms, and outbuildings, where they hunt rodents and other small prey. They are largely nocturnal, sheltering by day under rocks, debris, or within wall cavities and emerging at night to forage.
How to tell it apart from look-alikes
The plain olive coloration, generally lacking bold pattern elements, helps distinguish this species from house snakes with visible stripes or streaking, such as the Aurora House Snake's bright dorsal stripe. It can closely resemble other subtly patterned house snakes in overlapping ranges, where color tone and minor scale characteristics are needed to differentiate them precisely. Its smooth scales, small non-triangular head, and round pupils confirm its identity as a nonvenomous species distinct from venomous snakes that might share similar habitats.
