Watch out for snakes, expert warns as heavy rain brings increased reptile activity

Durban’s heavy rainfall is likely to bring to the surface certain potentially dangerous snakes, as well as less harmful ones.

James Wittstock, reptile curator at Crocworld Conservation Centre, on the KwaZulu-Natal south coast, said these species of snakes were seeking safety above the ground.

“With the rain comes the smaller fossorial species, which are snakes that spend most of their time beneath the surface of the ground. As the water levels rise, the oxygen levels diminish and these snakes are forced to leave their subterranean homes.

“While most of these are harmless to humans, there are certain species that could be potentially dangerous,” he said.

Wittstock said the most common fossorial snakes in the area are the Bibron's blind snake, which is harmless, and southern stiletto snake, which has a potent cytotoxic venom.

“A bite from a southern stiletto snake is very painful and causes moderate to severe swelling in most cases. If left untreated, it could lead to the loss of a limb or digit, as the venom breaks down the tissue cells surrounding the bite.”

Wittstock said the heavy rains were likely to see these species of snakes seeking refuge in and around homes.

“This is generally because they are seeking warmth and food. It is not uncommon for snakes to be found in the roofs of houses, where it is dry and they can hunt rats and geckos.”

He said if a snake is encountered, the best thing to do is to keep an eye on it from a safe distance, while calling a professional to retrieve it.

“Attempting to capture or kill the snake is both unnecessary and incredibly dangerous, as it is when most bites occur.”
