Copuetta lacustris occurs in Central, East, and Southern Africa, including Botswana, Eswatini, Lesotho, Mozambique, Zimbabwe, and South Africa.[2] In South Africa, it is found in all nine provinces at altitudes ranging from 4 to 1,676 m above sea level.[2]
The species has been recorded from numerous locations across South Africa, including Karoo National Park, Free State National Botanical Gardens, Kruger National Park, and Lowveld National Botanical Gardens.[2]
The species is frequently collected in urban areas and is often seen inside houses at night, especially during spring.[2] Egg sacs are approximately 8 mm in diameter and are constructed under bark in natural habitats and under window sills, door frames, and wooden structures in and around houses.
