How to Control Rodents in Your Home

Rodents are more than a nuisance. Once rats or mice get inside, they can contaminate food, damage insulation, chew wiring, and leave droppings in hidden areas. The longer they stay, the harder they are to remove.

The good news is that rodent control does not start with guesswork. It starts with a clear plan that works effectively. Remove what attracts them, block how they get in, and deal with active infestations properly.

At Eco Pest Control Perth, we always recommend starting with the basics before the problem grows.

How to Get Rid of Rats and Mice?

1. Remove what attracts rodents

According to the Victorian Department of Health, the most common pest rodents around homes are the Norway rat, roof rat and house mouse. The department says effective control starts with hygiene, less access to food and water, less shelter and sealed entry points.

In practical terms, that means keeping pantry items in sealed containers, cleaning up crumbs and spills quickly, keeping bins tightly closed, fixing leaking taps and reducing clutter in sheds, garages and storage areas.

It also helps to remove fallen fruit, outdoor pet food and garden waste, and to regularly check that bin lids are secure. Even small gaps around doors, vents, pipes and walls can be enough for mice to squeeze through. Blocking those holes with mesh or another durable material can help prevent them from getting in.

That is why prevention is such an important part of long-term rodent control.

2. Know the warning signs

Most rodent infestations show early clues before you see an animal. You may notice droppings in cupboards, gnaw marks on packaging, scratching sounds in the roof, or greasy rub marks along skirting boards and walls.

Another warning sign can be a strong urine smell or activity along a regular path inside the home. These signs usually mean rodents are already active inside or around the property.

Rodents are often most active at night, so noises after dark should not be ignored. Catching the issue early can make a major difference. A small problem is much easier to manage than a widespread infestation. Once activity spreads into the roof void, wall cavities or outdoor nesting areas, the job becomes harder.

3. Use traps carefully for smaller infestations

Based on guidance from NSW Health, traps can be a practical option for a smaller indoor rodent problem, especially after you reduce food access and seal likely entry points. A trap may be possible for a single problem area, but larger infestations usually need a broader response.

They are usually most effective along walls, behind appliances or in areas where rodent activity is obvious. They should not be placed near food preparation surfaces. The same guidance also notes that rodent-related infections are rare.

Even so, sensible hygiene precautions are still recommended when handling rodent droppings, nests or contaminated materials. Open the air flow if you can and clean the area safely.

4. Be cautious with rodent bait

The NSW EPA notes that pesticide products in Australia must be registered and used strictly according to the label, including directions for safe use, storage and disposal.

That means baits should never be used casually. It should not be placed where children and pets, or non-target animals may be exposed.

Householders should also never use agricultural bait products in domestic settings unless the product is specifically approved for that use. Used incorrectly, bait can create extra risks and still fail to solve the underlying problem.

Why rodent problems keep coming back

One of the biggest mistakes property owners make is treating only the visible activity. Traps may catch one or two mice. But if food is still available, shelter is still nearby and entry points remain open, new rodents can move in again.

They will keep returning to the same building for food, warmth and shelter, which can allow the problem to spread.

That is why proper rodent control is not just about removal. It is about stopping the conditions that allow the infestation to continue. A complete solution usually includes inspection, proofing, sanitation advice and targeted treatment where needed.

When to call a professional rodent control service

If you are hearing movement in the roof, noticing repeated rodent activity, or dealing with a larger infestation, it is usually time to bring in a professional. A trained technician can identify nesting sites, locate access points and recommend the safest and most effective treatment for the property.

At Eco Pest Control Perth, we help homeowners deal with rodent problems using practical treatment plans. These plans support managing larger infestations and controlling the risk of rodents coming back.

If you are unsure what to do next, contact a professional to ensure the problem is handled properly.

Final thoughts

Rodent control works best when you deal with the cause, not just the symptoms. Remove food and water sources, reduce clutter, seal access points, and use traps or bait carefully where appropriate. When the infestation is larger or keeps coming back, professional help can save time, reduce risk and give you a more reliable result.
