In a surprising and unsettling discovery, a resident of Horsley Park, a suburb in western Sydney, uncovered a nest of 102 venomous snakes in their backyard. The incident, which was handled by snake experts from Reptile Relocation Sydney, served as a stark reminder of the co-existing habitats of humans and reptiles, brought closer by urban expansion.
David Stein, the homeowner, had initially detected a group of about six snakes slithering in a mulch pile within his yard. Concerned for his safety and that of his family, he called in professional assistance. What followed was an ordeal that revealed a much larger problem than anyone had anticipated. The team led by Cory Kerewaro, an experienced snake catcher, arrived expecting to deal with a handful of reptiles. However, the situation escalated rapidly as 102 red-bellied black snakes, including five adult females and 97 recently birthed juveniles, were found hidden within the mulch.
“We were stunned, to say the least,” reported Kerewaro. “You don’t often see this level of congregation among these snakes. It was a clear case of multiple females grouping to give birth in what seemed like a relatively safe environment—a phenomenon likely caused by habitat fragmentation.”
The red-bellied black snake, native to eastern Australia, is known for its glossy black scales and crimson underbelly. Although their venom is considered less dangerous compared to other Australian snakes, they are still highly venomous and capable of delivering serious bites. Their preferred habitats include swamps, grasslands, and forests, but they are increasingly being pushed into urban environments.
Stein recounted the moment he unearthed the snake population: “When I first saw a few snakes in the mulch pile, I thought it was alarming enough. I could never have imagined that there were around a hundred, some no bigger than a shoelace.”
The snakes were carefully removed over a span of several hours. Each was bagged and taken to a designated relocation site far from residential areas. The relocation team emphasized the importance of not harming such reptiles, which play a crucial role in controlling rodent populations and maintaining ecological balance.
The incident comes amid a broader pattern in Australian suburban locales, where rapid urban sprawl is forcing native wildlife to adapt or move closer to human settlements. Experts warn that findings like these could become more frequent, particularly as conservation of natural habitats continues to lag behind development.
“Such incidents highlight the need for urban planning that prioritizes the natural ecosystems of our native fauna. Retaining green spaces and ensuring safe corridors for wildlife movement is essential if we want to reduce these interactions,” said Professor Sarah Turnbull, a wildlife conservationist from the University of Sydney.
Beyond habitat considerations, authorities also urge homeowners to regularly inspect their properties for favorable snake shelters, especially during warmer months. Mulch piles, wood stacks, and dense bushes are common areas where snakes may take refuge.
Despite the frightening discovery, Stein commended the swift and professional response of the snake relocation service. “They stayed calm, kept us informed throughout, and handled all the snakes humanely. It’s reassuring to know such professionals are available when something this scary happens.”
He has since cleared the mulch pile, installed barriers, and consulted a local pest control expert to further ensure his property is less hospitable to uninvited guests. Yet, he admits it will take some time for his family to feel entirely at ease outdoors.
As summer temperatures drive more snakes out of hiding in search of water and prey, experts recommend other Sydney residents remain vigilant. They estimate that over the next few months, cases of human-snake encounters could rise, given the overlapping living spaces of both species.
This extraordinary event stands as both a cautionary tale and a call to action for urban residents across Australia to better coexist with their native wildlife. It also sheds light on the necessity for innovative urban planning that features harmony rather than confrontation with nature.
