It starts with a sound.
A faint scratching. You lie in bed at 2am, ears perked, telling yourself it’s just the house settling. Maybe the wind. Maybe the cat.
But the cat is right there with you — wide awake, staring at the ceiling.
That sound is almost certainly rats or mice. And by the time you hear it, the infestation is already well underway.
Across Melbourne’s south east, rodent calls spike every autumn and winter as temperatures drop and rats and mice go looking for somewhere warm to nest. Properties in Cranbourne, Berwick, Dandenong, Springvale, Noble Park, Rowville, Keysborough, and surrounding suburbs are particularly vulnerable — thanks to older housing stock, established garden corridors, and proximity to open paddocks and waterways.
If you’ve heard that sound — or found any of the signs we’re about to describe — this guide is for you. We’ll walk you through exactly what to look for, why rodents are a far bigger threat than most people realise, and how Abby’s Pest Control removes them safely and completely.
Important: Rats and mice don’t stay small infestations for long. A female rat can produce up to 84 pups per year. A single mouse pair can grow into a colony of hundreds within months. Every week you wait makes the problem harder — and more expensive — to fix.
Melbourne’s south east corridor — stretching from Dandenong down through Cranbourne, Berwick, Clyde, and Langwarrin — has specific conditions that make rodent problems particularly common.
Suburbs like Springvale, Noble Park, and parts of Keysborough and Mulgrave have a large proportion of homes built in the 1970s and 1980s. These properties have more gaps, cracks, and ageing roof cavities than newer builds. Mice can squeeze through a gap as small as 6mm. Rats can enter through a hole the size of a 20-cent coin.
The Cranbourne–Berwick–Clyde area borders significant green corridors, wetlands, and rural land. These areas support large wild rodent populations that move into residential streets as the seasons change. Properties in Lynbrook, Lyndhurst, Devon Meadows, and Beaconsfield are at elevated risk.
As temperatures drop across Melbourne, rodents move inward. Roof voids, wall cavities, subfloors, garages, and kitchen cabinetry become prime nesting spots. By the time most homeowners in Rowville or Heatherton notice the problem, the colony is already established.
Knowing which rodent you’re dealing with matters for treatment. Rats and mice have different behaviours, habitats, and respond to different control methods.
The most common rodent in Melbourne homes. Small body (70–95mm), light brown to grey, large ears and thin tail. Mice are curious and explore new objects, which can help with trapping. They nest close to food sources — most often in kitchens, pantries, and inside cabinetry.
Also called the black rat. Slender body with a long tail (150–200mm). An agile climber. When you hear scratching in the ceiling in Berwick or Rowville, there’s a good chance it’s roof rats. They enter through roof tiles, eaves, and gaps in fascia boards.
The large brown rat — heavy-bodied (200–280mm), shorter thick tail. Norway rats burrow and invade from ground level — through subfloor spaces, drainage pipes, and gaps at ground level. Common near older sewer lines in Dandenong, Springvale, and Noble Park. They cause the most structural damage.
Rodents are experts at staying hidden. Most homeowners only realise they have a serious infestation after several of these signs appear together. The earlier you act, the easier and cheaper the fix.
Most people think of rodents as unpleasant but not dangerous. That’s a serious underestimation.
The fire risk nobody talks about: Rodents have continuously growing incisors and must gnaw constantly. Inside roof voids and wall cavities, the most accessible things to gnaw on are electrical cables. If you have an active rodent infestation in Mulgrave, Dandenong, or Heatherton, your wiring may already be at risk. This is not a problem that can wait.
A trap catches a rodent. It doesn’t find the nest, doesn’t seal the entry points, and doesn’t address the colony. Here is how Abby’s Pest Control approaches a rodent job properly.

Here’s why DIY traps keep selling and rodent problems keep coming back:
Walk the perimeter of your home and look for gaps around pipes, cracks in the foundation, open eaves, and poorly fitted door seals. Steel wool and expanding foam sealant are your best tools. Remember: mice need a gap of only 6mm.
Store pet food, birdseed, and dry goods in hard plastic or metal containers with sealed lids. Do not leave food scraps on the bench overnight. Keep compost bins sealed and away from the house wall. In gardens across Beaconsfield and Devon Meadows, clean up fallen fruit regularly.
Overgrown gardens, wood piles, compost heaps, and dense ground cover close to the house are rodent highways. Keep at least 30cm of clear space around the house perimeter and move wood stacks away from the building.
Dripping taps, blocked drains, and standing water attract rodents as much as food. Fix leaks promptly and ensure gutters drain properly — especially important for homes in Lyndhurst and Lynbrook near low-lying areas.
The most cost-effective rodent control is catching problems before they become infestations. An annual inspection from Abby’s Pest Control gives you visibility on the parts of your property — roof voids, subfloors, wall cavities — that you cannot check yourself.
Abby’s Pest Control is a family-owned business based right here in Melbourne’s south east. When you call 0431 270 152, you speak to Abeer directly — the licensed technician who will come to your home.
Why choose Abby’s:
Rat droppings are larger (12–18mm, blunt ends), while mouse droppings are smaller (3–5mm, pointed ends). Rats also make louder noises in the ceiling. If you’re unsure, Abby’s Pest Control offers same-day inspections across Cranbourne, Berwick, and surrounding areas.
Yes. Abby’s Pest Control uses child and pet-friendly products that meet Australian safety standards. Bait stations are tamper-resistant and placed in locations inaccessible to children and animals.
Very fast. A female rat can produce up to 84 offspring per year. A pair of mice can grow into a colony of hundreds within months. In Dandenong’s older housing stock, rodents can spread through roof voids and wall cavities to the entire property within weeks.
Yes. Abby’s Pest Control provides same-day service across Springvale, Noble Park, Keysborough, Lynbrook, and all surrounding suburbs. Call 0431 270 152 to book an urgent inspection.
Yes — this is one of the most serious risks. Rodents gnaw through electrical wiring inside wall cavities and roof voids. Many unexplained house fires across Melbourne’s south east are caused by chewed wiring. Don’t wait if you’re hearing noises in the ceiling.
DIY traps catch individual rodents but never address the colony, the entry points, or the nesting sites. Professional rodent control involves a full property inspection, strategic baiting, entry-point sealing, and follow-up to fully resolve the infestation.
A standard residential treatment takes 60–90 minutes. Most infestations show significant reduction within 48–72 hours. A follow-up visit is usually scheduled 2–4 weeks later to confirm elimination.
