Learn Everything About Rodent Control in Melbourne. You must have knowledge about the signs you have of rats or mice and what you must do.
Introduction
There are few things more unsettling than scratching sounds in your walls at night. Or finding droppings along your kitchen bench. Or discovering something has chewed through the corner of your cereal box.
Rats and mice are a reality for many Melbourne households, particularly as the weather cools and rodents start looking for warm places to nest. And once they’re in, they don’t leave on their own. Our professional rodent control service is designed to deal with the problem thoroughly, at the source, not just at the surface.
In this guide, let’s explore rodent control in Melbourne, including the signs to look for, why DIY solutions fall short, and what professional treatment actually involves.
Why Rodents Are a Bigger Problem Than You Might Think
A single pair of mice can produce up to 60 offspring in a year. What starts as one or two quickly becomes a significant infestation. Beyond numbers, rodents chew through electrical wiring (a serious fire hazard), gnaw on timber, insulation, and plumbing, and contaminate food with droppings and urine.
As we detail in our blog on the dangers and health threats of rats and rodents, they’re also known carriers of leptospirosis, salmonella, and hantavirus. Our post on protecting your family against diseases carried by mice and rats is worth reading if you have children or elderly family members in the home.
For business owners the stakes are even higher, a rodent sighting in a restaurant or retail space can trigger council inspections and cause severe reputational damage. We cover this specifically in our post on how to ensure your restaurant stays rodent-free.
How to Tell If You Have Rats or Mice
Correct identification matters because rats and mice require different treatment approaches.
Signs of mice
- Small dark droppings (3–5mm, like grains of rice)
- Fine gnaw marks on food packaging, timber, or cables
- Nests of shredded paper or fabric in quiet corners
- A faint musty smell in cupboards or behind appliances
Signs of rats
- Larger droppings (10–20mm, dark and oval)
- Burrow holes in gardens or under structures
- Grease marks along walls where they regularly travel
- Heavier gnaw damage on harder materials like plastic pipes
- Loud scratching in walls, ceilings, or subfloor, especially at night

Where Rodents Hide in Your Home
Rats nest in subfloors, roof voids, garden areas, under concrete slabs, and overgrown vegetation. They’re strong climbers and can access roof spaces via downpipes, trees, and cables.
Mice can squeeze through gaps as small as 6mm and nest inside wall cavities, behind kitchen units, and inside appliances. Common entry points include gaps around pipes, damaged roof tiles, open vents, broken door seals, and foundation cracks.

Why DIY Rodent Control Usually Fails
Most DIY products, traps, bait stations, ultrasonic repellers, deal with the symptom, not the source. Trapping a few mice doesn’t address the colony or the entry points. Snap traps and glue boards require precise placement based on rodent behaviour that most homeowners simply don’t have knowledge of.
Rodenticide baits carry real risks when used without professional knowledge, particularly around pets and children. Getting placement and dosage wrong can make a rodent problem harder to resolve.
Ultrasonic devices have very limited evidence behind them. Rodents adapt quickly to environmental disturbances. For a proper solution, our rodent control service targets the problem systematically, colony, travel routes, entry points, and all.
What Professional Rodent Control Involves
When you call Positive Pest Solutions for rodent control in Melbourne, here’s what happens:
- Thorough inspection – inside and out, identifying species, entry points, nesting areas, and travel routes.
- Targeted bait station placement – tamper-resistant professional-grade stations placed strategically, not randomly.
- Exclusion advice – sealing gaps, repairing vents, and removing easy access points to prevent reinfestation.
- Follow-up monitoring – checking stations and assessing activity levels. Rodent control often takes more than one visit.
- Practical guidance – securing bins, managing compost, and removing food attractants.

Preventing Rodents From Coming Back
Treatment deals with the current problem. Prevention stops it returning. The most effective steps:
- Store all food – including pet food and bird seed – in airtight containers
- Keep rubbish bins sealed and positioned away from the house
- Eliminate clutter in garages, sheds, and storage areas
- Trim trees and shrubs away from the roofline
- Seal gaps around pipes, vents, and entry points
- Fix leaking taps and remove standing water sources
- Consider a regular pest control maintenance program for ongoing monitoring
