Grantham Farm is at the leading edge of the Blacktown LGA growth corridor — one of the newer suburbs in the Riverstone / Marsden Park development zone, with construction still active across substantial parts of the area. The pattern that produces is consistent across growth-corridor suburbs in Western Sydney: as paddock and Cumberland Plain woodland are progressively cleared and replaced with new homes, the resident snake population doesn’t disappear. It gets pushed sideways. Some of it ends up on the next paddock over, waiting to be displaced again. Some of it ends up on the active building site itself. And a substantial proportion of it ends up in the brand-new yards that have just been completed — where the residents have only just moved in, have no history with the area, and are not expecting to be sharing the backyard with an Eastern Brown.
We attend Grantham Farm regularly, and the work here is genuinely seasonal in character — heavy through the construction-active warmer months, with a clear concentration of callouts on the streets where building is most active.
If you have spotted a snake in Grantham Farm, call Sydney Snake Catcher on 1300 599 938. We are the original and longest-running snake catching business of its kind in NSW, licensed, insured, and available every day of the year.
Stay calm and step back. Bring children and pets indoors. On a building site, stop work in the affected area and move workers to a safe distance. If possible, keep watching the snake until we arrive. Call 1300 599 938.
You do not need to take a photo. You do not need to identify the snake. You do not need to follow it or get close. But if you can, try to keep a visual on the snake from a safe distance. If it disappears into cover, keep watching the spot where you last saw it — snakes will often reappear within minutes once the area goes quiet. Knowing where the snake last was makes our job much faster when we arrive. We stay on the phone with you, explain everything clearly, and guide you through the process from the moment you call.
Grantham Farm sits within the South Creek catchment, bordered by Riverstone, Marsden Park and Schofields. The land it occupies was, until very recently, a mix of farmland, paddock and Cumberland Plain woodland — the kind of landscape that supports a steady population of Eastern Brown Snakes through the dry margins and Red-bellied Black Snakes along the creek lines. That population has been in this corner of Western Sydney for far longer than the modern suburb, and the construction of the estate has not removed it. It has simply rearranged it.
The pattern we see consistently in growth-corridor suburbs like Grantham Farm: snake callouts spike during the years a new estate is being built and stay elevated for several seasons afterwards while the landscape settles. Active construction displaces snakes from cleared land into adjoining yards, into under-construction blocks and into the brand-new homes that have just been completed. Stockpiled bricks, pavers, dunnage, demountable site offices, retained vegetation strips and unmowed verges along under-construction blocks all act as snake habitat in the meantime.
Properties on the development edge see the most activity. Properties backing onto retained vegetation, drainage corridors or active construction blocks see almost as much. Once the streets settle — landscaping completes, gardens mature, surrounding development stabilises — callout volumes drop, but they don’t go to zero. The South Creek catchment keeps delivering snakes through the creek and drainage corridors.
Eastern Brown Snake — the species we encounter most often in Grantham Farm. Browns thrive in the open grassland, disturbed bushland, paddock margins and active construction zones that define a growth-corridor suburb. They follow mice and rats, and construction sites, recently graded blocks and the edges of new estates are rodent-rich environments. Browns will travel along fence lines, drainage easements and undeveloped corridors without warning. Fast, alert, highly venomous. Step back, keep a visual from a safe distance, and call us.
Red-bellied Black Snake. Common along the South Creek and First Ponds Creek tributaries that thread through the wider area, and in the wetter sections of retained reserve and drainage corridor. They will move into adjoining backyards from these corridors — particularly properties with pools, ponds or thick garden beds, and properties along the wetter retained vegetation. Venomous, but generally far less defensive than browns. They will move away if given the chance.
Blue-tongued Lizard. Not a snake, but the reptile we are called for almost as often. Blue-tongues are large, slow-moving native skinks that get mistaken for snakes because of their size and the way they flatten their bodies when threatened. They are harmless, beneficial, and good for a garden — they eat snails, slugs and beetles. We will attend, identify the animal on site, and where appropriate either leave it where it is or relocate it to a safer part of the property.
The hiding spots vary based on whether the property is residential and complete, brand-new, or still under construction.
On active building sites: stockpiled bricks, pavers and rubble. Dunnage piles and stacked materials. Demountable site offices and storage containers — particularly the corners and bases. Long grass strips around the perimeter of a build. Retained vegetation between blocks. Unmowed verges along the boundary. Under tarps and covered material stacks that haven’t been moved for days.
On newly completed homes in their first one or two seasons: garage corners and the gaps under garage rollers — particularly common on properties where the garage seals haven’t bedded down yet. Retaining walls and rock features (Grantham Farm uses a lot of them). Newly planted garden beds with thick mulch, before they have grown in. Pool pump housings on properties with completed pools. Sheds and storage areas. Around chicken coops and outdoor pet bowls.
On established residential blocks: the standard pattern across the suburb. Pool pump housings, garden beds with mulch, retaining walls, under decks and verandahs, along fences backing onto retained vegetation, drainage corridors or under-construction blocks.
The reptile-deterrent products at hardware stores — powders, sprays, ultrasonic devices — do not work. Skip them. What does help in a growth-corridor suburb like Grantham Farm is anything that addresses the specific conditions of a new estate.
For residents in newly completed homes, the most useful things are: reducing rodent activity around the property, sealing gaps around the garage roller and under external doors (new homes often have unsealed gaps for the first season or two), keeping grass short along boundary fences (particularly the side facing retained vegetation, drainage corridor or under-construction blocks), thinning out new garden beds before they grow thick enough to harbour snakes, and keeping pool pump housings clear and unappealing as shelter.
For active building sites, the most useful things are organised stockpiles, materials moved rather than left in place for weeks, mowed grass along the build perimeter, tarps lifted and stacked materials rotated regularly, and active rodent control on the site. Reducing the rodent population is by far the single most effective measure for Eastern Browns specifically.
A snake inside a Grantham Farm home or on an active building site is an emergency. New builds with unsealed garage rollers and partially landscaped yards are particularly vulnerable in their first one or two seasons — we attend snake-inside-the-house jobs across Grantham Farm regularly through the warmer months. Building site sightings are equally common, and we attend these as required, working alongside site WHS protocols and providing documentation for incident records on request.
We respond as quickly as we can, locate the snake, remove it safely, and check the building or site is secure before we leave.
Sydney Snake Catcher is the original and longest-running snake catching business of its kind in NSW. We operate the largest network of qualified snake catchers in the state — when you call, the catcher closest to you is dispatched. Grantham Farm sits in the Marsden Park / Riverstone growth corridor, which is one of our highest-volume work zones across the entire network, and we have catchers in the corridor on most operational days through the season.
We work calmly, without panic, and without making anyone feel judged about the state of their property or site. Snakes turn up in Grantham Farm because the suburb is being built on top of active snake country — that is the landscape, not the housekeeping. We explain what we are doing, what species we are dealing with, why the snake is there, and what — if anything — can be done to reduce the chance of the next one settling in. For builders and site managers, we provide the documentation you need for WHS and incident records.
If you see movement, hear rustling, or notice your pet, your kids or your workers fixated on one area, call 1300 599 938 immediately.
Why are there so many snakes in new estates like Grantham Farm?
Active construction displaces snakes from former farmland and Cumberland Plain woodland into adjoining yards, building sites and the brand-new homes that have just been completed. The resident snake population doesn’t disappear when an estate is built — it gets pushed sideways. New estates also offer warm slabs, retaining walls, fresh landscaping and rodent activity. We see consistently elevated callout numbers across new-build suburbs in their first several seasons.
What snake is most common in Grantham Farm?
The Eastern Brown Snake, by a clear margin. The mix of paddock margins, active construction, disturbed bushland and rodent-rich new-build environments favours them. Red-bellied Black Snakes are second, generally closer to the South Creek drainage corridors.
What should I do if I find a snake on a building site in Grantham Farm?
Stop work in the affected area and move workers to a safe distance. Keep a visual on the snake if you can do so safely. Do not attempt to move it. Call Sydney Snake Catcher on 1300 599 938. We will attend, remove the snake and provide documentation for incident records on request.
My home is brand new — why am I seeing snakes already?
This is the most common pattern across Grantham Farm. The snake population was here before the house was. New garages and new builds also have small gaps and unsealed seams that bed down over the first season or two. Sealing those gaps, keeping rodents down, and managing the immediate surrounds of the property all help.
How quickly can a snake catcher get to Grantham Farm?
We operate the largest network of snake catchers in NSW and dispatch the catcher closest to you. Grantham Farm sits in our high-priority growth-corridor service zone and we have catchers in the area on most operational days. Response times vary with traffic and existing jobs, and we prioritise active sightings.
