To prevent snakes, keep gardens tidy, mow lawns regularly, remove piles of debris, control rodents, store pet food securely and reduce hiding places around your property. Snakes are often attracted by shelter, water and prey sources, so removing these attractants can make your home less appealing

Australia has around 140 land snake species, but only 10-15% pose fatal risk to humans. Bite fatalities in Australia average less than 2 per year — source: Australian Museum.

Do rats attract snakes in Sydney yards?

Yes — rodents are the single biggest food source for most venomous and non‑venomous snakes found across Sydney suburbs. Remove rats, and you remove the main reason many snakes choose to stay on your property.

Our 2024–2025 service records show 70% of residential snake call‑outs were to homes with confirmed rodent activity. Eastern Brown Snakes, the species responsible for most Australian bite incidents, feed up to 80% on small mammals like mice and rats — source: Australian Museum.

In Sydney, warmer spring and summer months bring both rodent breeding peaks and increased snake movement. Where you see regular rat droppings, gnaw marks, or burrows near the house, you are statistically far more likely to also have snakes hunting those same areas.

How the rat‑to‑snake chain works

  1. Pet food, fallen fruit, or rubbish attracts rats and mice
  2. Rodents breed quickly — a single pair can produce 50+ offspring in 6 months
  3. Snakes detect the scent and movement from 50+ metres away
  4. They move in, find shelter nearby, and keep returning while food remains

Rat activity vs. snake visit risk

Rat activity level Signs you will see Snake attraction risk
Low / Occasional Droppings once in a while, no gnawing Low — snakes may pass through
Moderate Regular droppings, chewed food packets Medium — higher chance of hunting visits
High / Infestation Noises in roof/walls, burrows, runways Very High — snakes may take up residence

For Sydney businesses, rodent presence is also a critical non‑conformance under the Australia New Zealand Food Standards Code — source: Food Standards Australia New Zealand. Combined with snake risk, it creates both health and legal exposure.

Breaking the cycle means treating rodents first, then closing up access points and removing shelter. Snake‑proofing alone rarely works long‑term if a reliable food source is still available on the property.

Section Summary: Rats are the #1 reason snakes visit Sydney yards. 70% of snake call‑outs link to rodent activity. Control rats first, then remove shelter and water to stop snakes returning.

Why do snakes come into Sydney yards and houses?

Snakes enter areas for three simple reasons — they are looking for food, water, or shelter. If you remove these, you remove the main reason they stay.

Rodent activity is the number one trigger: 70% of snake call-outs we attend link back to mice or rats nearby — our 2025 service data.

  • Food source: rodents, frogs, birds, insects
  • Water source: dripping taps, ponds, pet bowls
  • Shelter: long grass, piles of wood, leaves, rubble
Section Summary: Snakes follow food, water, and cover. Fixing rodent issues and removing hiding spots stops most visits.

What should I do if I find a snake in my home or yard?

Stay calm — snakes usually avoid people. Panic and sudden movement can trigger defensive behaviour.

  1. Stop and keep still
  2. Move children and pets indoors immediately
  3. Watch from a safe distance — do not chase or corner it
  4. Do NOT touch, pick up, or try to move it
  5. Call a licensed snake catcher or pest controller

Killing snakes is illegal in NSW without a permit — penalties can exceed $5,000 — source: NSW Department of Planning and Environment. They control rodents and keep ecosystems balanced.
