Rat & Mouse Control Sydney
Rats and mice do real damage, chewing wiring, spreading disease and breeding fast in roof voids and wall cavities. We clear them with a proper program, then seal the gaps so they cannot come back.
A rodent problem rarely stays small. Rats and mice breed quickly, and a few that move into the roof in autumn can become a serious infestation by winter. Beyond the noise and the mess, they gnaw through electrical wiring, which is a genuine fire risk, and they spread disease through their droppings and urine.
Bob Pest Control clears rats and mice across Bankstown, Liverpool, Fairfield and the wider South West. We do more than scatter a bit of bait. We find how they are getting in, treat the active areas safely, and seal the entry points so the problem is actually solved rather than paused.
Sydney Rat and Mouse Species
Three rodents account for almost every job we see across the South West. Each lives differently, which changes where we treat.
Roof Rat
A nimble climber, also called the black rat. It nests up high in roof voids and ceilings, which is why so many people first hear it overhead at night.
Norway Rat
The larger brown rat. It burrows at ground level, under slabs, in gardens and around drains and the subfloor, rather than climbing.
House Mouse
Small and curious, nesting in wall cavities and cupboards. They breed very fast, so a couple of mice can become a real problem in weeks.
Signs of Rodent Activity
Rodents are mostly active at night, so you often notice the evidence before you see one. These are the giveaways.
Droppings
Small dark droppings along walls, in cupboards and in the roof void.
Noises at Night
Scratching or scurrying in the ceiling and walls after dark.
Gnaw Marks
Chewed wiring, food packaging, skirting and stored items.
Smear Marks
Greasy brown marks along the runways they use again and again.
Musty Smell
A sharp, ammonia-like odour that builds as numbers grow.
Nests
Shredded paper, insulation and fabric tucked into hidden corners.
Our Rodent Treatment Process
A complete program of baiting, trapping and exclusion, because clearing the rodents and sealing the gaps go hand in hand.
Inspect & Identify
We work out which rodent it is, how many, and where they are getting in and nesting.
Bait & Trap
We place bait in tamper-resistant stations and set traps in the active areas, kept safely out of reach.
Seal Entry Points
We find and block the gaps, pipes and eaves gaps they use, which is the part most people miss.
Follow-Up
We check back to confirm the activity has stopped and top up where a heavy infestation needs it.
Roof Void Treatment
In Sydney, the roof void is where most rat problems live. Roof rats are agile climbers that follow tree branches, fences and pipes up to the roofline, then slip in through surprisingly small gaps in the eaves and around penetrations. Once inside, the warm, undisturbed ceiling space is the perfect nesting spot.
We treat the roof void directly, placing bait and traps where the rats are active, and just as importantly we trace and seal the entry points feeding the problem. Sealing those gaps is what stops a fresh family of rats simply replacing the last one a few weeks later.
Common Entry Points
- Gaps in the eaves and roofline
- Around pipes, cables and air-con penetrations
- Overhanging branches that reach the roof
- Weep holes and gaps in brickwork
- Damaged vents and broken tiles
Why DIY Traps Don't Work for Infestations
A couple of snap traps from the hardware store can catch the odd mouse, and for a single stray that is often enough. The trouble starts with an actual infestation. Rodents breed faster than you can trap them, so for every one you catch there are several more breeding out of sight. You end up emptying traps for weeks while the numbers barely move.
There are two other problems. Rats in particular are wary of new objects, so they often avoid traps and shop-bought bait altogether. And even if you knock the numbers down, doing nothing about the entry points means a new group simply moves into the same warm roof void. A professional program clears the active rodents and seals the way in, which is the combination that actually ends it. Our guide on how to get rid of rats covers what you can do alongside a treatment.
