A snake that's disappeared will often reappear, but if we arrive and can't find it, we will need to leave. You don't need to take a photo or identify the species, just watch where it goes.

Why Thornleigh Gets the Snake Activity It Does
Thornleigh sits between Normanhurst and Westleigh, with the eastern side dropping into the Pennant Hills Park and Berowra Valley bushland system, and the western side running into the gully drainages that feed down toward Carlingford and Cherrybrook. The Pacific Highway and railway line bisect the suburb, with the residential streets on both sides backing onto reserve or gully country. The eastern side carries the heaviest bushland exposure and the highest concentration of callouts. There's also a light-industrial pocket on the western side along the railway and Bridge Street, which produces its own commercial and warehouse callout work.
Older Federation and mid-century homes on large blocks with deep established gardens through the central residential streets, newer infill and townhouse complexes around the station and along the Pacific Highway, and acreage-style holdings on the deeper bushland-edge streets. Pool density is high across the established sections. The combination of bushland exposure, sandstone country, mature gardens and the small industrial pocket produces a varied callout profile.
The Reptiles We Attend in Thornleigh
Diamond Python. A major species in our Thornleigh work, particularly on streets backing onto Pennant Hills Park, the Berowra Valley bushland or the connecting gully systems. Non-venomous, but large, adults reach two to three metres and they're powerfully built. The bushland exposure, mature gardens and older tiled-roof homes sustain a resident Python population, and roof cavities are a major job category. Pythons follow rodents into the roof and settle in. We also find them stretched across warm retaining walls, curled behind shrubs, on sandstone steps, in pergolas, along gutters and on warm driveways. They rely on camouflage rather than speed and usually stay still when you find them. If you hear soft movement in the ceiling or see one anywhere on the property, call 1300 599 938.
Red-bellied Black Snake. A substantial proportion of our Thornleigh work. Common along the gully drainages running through Pennant Hills Park and the Berowra Valley headwaters, and on properties with pools, ponds or thick damp garden beds. They follow frogs, so frog activity (particularly after rain and through the warmer months) tends to bring them through. Pool pump housings come up consistently. Venomous, but generally far less defensive than Browns. They will move away if given the chance.
Golden-crowned Snake. Common in Thornleigh, although most residents never see one. Small, nocturnal, with a pale crown-like marking across the head and a pink belly. During the day they shelter under sandstone blocks, loose bark, timber sleepers, pot plants, garden edging and leaf litter. The sandstone country and deep established gardens of Thornleigh give them ideal habitat. Venomous, but the bite causes only local symptoms in most cases and is not regarded as dangerous to adults, still warrants professional handling.
Green Tree Snake. Common in Thornleigh, particularly in mature gardens, along fences, in pergolas and around roof lines. Slender, bright green or olive, fast-moving, completely harmless. They feed on skinks, geckos and small frogs and are excellent climbers, which is why they sometimes turn up at elevated parts of the property.
Eastern Brown Snake. Present in Thornleigh, particularly on the drier blocks, around the light-industrial pocket along the railway and on properties with rodent activity, chicken coops or accumulated yard storage. Browns work the warehouse perimeters and back-of-house surrounds on the industrial side. Highly venomous. Step back, keep a visual from a safe distance, and call us on 1300 599 938.
Blue-tongued Lizard. Not a snake, but the reptile we are called for almost as often. 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 insects.
Which Species Follows What
The species mix in Thornleigh makes more sense once you know what each one is following. Diamond Pythons follow rats and mice, which is why they end up in roof cavities. Red-bellied Black Snakes follow frogs and moisture, which is why they concentrate along the gully drainages and around pool pump housings. Golden-crowned Snakes follow small lizards and skinks under leaf litter and sandstone. Green Tree Snakes follow skinks and geckos through gardens and along fence lines. Eastern Browns follow rodents through the drier blocks and along the industrial perimeter.
Where We Find Reptiles on Thornleigh Properties
For Diamond Pythons: roof cavities are the standout, particularly on older homes with tiled roofs and small gaps under the eaves. Also on sandstone retaining walls, in pergolas and outdoor entertainment areas, along gutters, curled behind thick shrubs, on sunny driveways and along fence lines facing Pennant Hills Park or the gully drainages.
For Red-bellied Black Snakes: pool pump housings, pool surrounds and water features, garden beds with thick mulch against boundary fences, under decks and verandahs in shaded damp corners, along fences backing onto the gully drainages or the wetter sections of reserve.
For Eastern Browns: garages, sheds with accumulated yard storage, around hot water systems, along long boundary fences. On the industrial side, around loading docks, behind warehouses, back-of-house bin surrounds, in maintenance yards and along long boundary fences.
For Golden-crowned Snakes: under sandstone blocks, around rockeries and leaf litter, beneath timber piles, paths and outdoor tiles, around damp sheltered corners of the garden.
For Green Tree Snakes: along fences, through pergolas, around roof lines, in mature shrubs and along garden edges.
What to Do If You See a Snake in Thornleigh
Step back. Bring children and pets indoors. If you're at a commercial premises in the Bridge Street industrial pocket, keep staff back and call us. If possible, keep a visual on the snake from a safe distance. Don't try to move it, contain it, photograph it from up close or identify the species. Call 1300 599 938. We'll talk you through what to do until we arrive.
If you hear movement in the roof through the warmer months and you live on a bushland-edge or gully street, a Diamond Python is one of the more likely explanations. Possums and rats are the others. We can tell the difference on site.
Snake Bite First Aid
A snake bite is a medical emergency. Treat every bite as if it's venomous, even if the snake looked harmless. Symptoms can take time to appear, and that's exactly why fast action matters.
If someone is bitten:
Australian antivenom is highly effective when administered promptly. Time matters.
What Actually Reduces Reptile Activity on a Thornleigh Property
Deterrent products sold at hardware stores, powders, sprays, ultrasonic devices, are not effective. Don't waste money on them.
For Diamond Pythons specifically, reducing rodent activity in the roof is the single most useful thing. Pythons follow rats. If a Python turns up in the ceiling, the rats got there first. Seal roof entry points where you can, keep the roof clear of stored items that draw rodents, and address roof rodent activity through proper rodent control.
For Red-bellied Black Snakes, keep pool pump housings clear and unappealing as shelter. Thin out heavy garden beds along boundary fences, particularly the side facing gully line or reserve. Manage frog activity where it has concentrated against the house, without killing the frogs, they're protected.
For Eastern Browns on residential blocks, reducing rodent activity is the most effective measure. Tidy sheds and outdoor storage. Seal gaps under structures. Keep grass short along boundary fences. On industrial sites, manage back-of-house bins, lift stored materials off the ground and maintain perimeter grass.
