Stein expressed concern that the snakes might return to the same mulch pile next year to give birth again, prompting him to plan its removal soon.

On February 7, 2025, a remarkable incident unfolded in Horsley Park, a suburb of Sydney, where snake catcher Dylan uncovered a total of 102 red-bellied black snakes, including 97 newborns and five adults, while searching through the mulch in a homeowner's yard.

The homeowners, David Stein and his partner, had been observing snakes in their mulch for over two weeks and initially believed only four snakes were present before contacting Reptile Relocation Sydney.

Cory Kerewaro, the owner of Reptile Relocation Sydney, led the team that was initially called to capture two snakes but ended up discovering an unusually large gathering of pregnant females.

Experts are puzzled by the congregation of so many pregnant snakes, speculating that it could be due to safety in numbers or habitat shortages, possibly exacerbated by recent hot weather.

Red-bellied black snakes are known for their behavior of congregating before giving birth, which led to this extraordinary find.

This incident marks the largest group of venomous snakes Kerewaro has encountered in a removal job, surpassing previous cases of 30 non-venomous carpet pythons.

The final count of the captured snakes included five adult females and 95 babies, making this a uniquely fortuitous event in snake-catching circles.

Due to the large number of snakes, Kerewaro received special permission to release them into a national park, ensuring their safe return to the wild away from human interaction.

Australian law requires that reptiles be released within a 20 km radius of their capture site, which Kerewaro complied with by relocating them to a designated isolated area.

Kerewaro humorously referenced the classic children's story 'The Hundred and One Dalmatians' in a social media post, stating 'How about 102 redbellies!'

The incident has been documented in a video shared by Reptile Relocation Sydney, showing dozens of red-bellied black snakes writhing in a bucket.
