Common Household Pests in Melbourne and How to Deal With Them

Aug 10, 2026

A pest problem rarely starts with a dramatic invasion. It might be a few ants around the kitchen bench, a cockroach disappearing behind the fridge or a mouse scratching somewhere behind the walls at night. Before long, you’re seeing them more often and wondering where they are coming from. Pest Control in Melbourne can help when household pests become difficult to manage, but knowing what attracts them is just as useful. Different pests behave differently, so the right response depends on what you’re dealing with.

Why do pests get into Melbourne homes?

Pests come inside for fairly simple reasons. They are looking for food, water, warmth or somewhere sheltered.

A home can offer all four without you realising it. Food crumbs under appliances, a dripping tap, an overgrown garden or a small gap under a door can be enough to make a property easier for pests to enter and stay in.

Melbourne’s changing weather can also affect pest activity. You may notice more insects during warmer periods, while mice and other pests may look for sheltered places when outdoor conditions become less comfortable.

The first step is to work out what has attracted the pest. Otherwise, you can spend a lot of time dealing with the ones you see while the reason they keep returning remains untouched.

1. Ants

Ants are one of those pests that seem to appear out of nowhere.

One day the kitchen is clear. The next, there is a line of ants heading towards a cupboard or food left on the bench.

They are usually looking for food or water. Once they find a reliable source, other ants can follow the same route.

What can you do?

Start by removing whatever is attracting them. Keep food in sealed containers, wipe down surfaces and clean up spills as soon as possible. Pay attention to where the ants are entering, too.

Killing the ants you can see may give you a temporary break, but it may not deal with the colony. If ants keep returning, it is worth finding out where they are coming from and why they have chosen that route.

2. Cockroaches

Cockroaches are not always easy to spot. They tend to stay hidden during the day and become more active when the house is quiet.

Kitchens and bathrooms are common problem areas because cockroaches can find food, moisture and shelter there. They can also hide behind appliances, inside cupboards and in small gaps.

What can you do?

Keep food sealed and clean crumbs and spills promptly. Empty rubbish regularly and deal with leaking taps or other moisture problems.

If you are seeing cockroaches repeatedly, especially during the day, don’t assume the one you saw is the only one there. Repeated sightings are a good reason to have the property assessed.

3. Spiders

A spider in the garden is not unusual. Finding webs around your windows, garage and inside the house every few days is more frustrating.

Spiders are often attracted to areas where insects are plentiful. Gardens, outdoor lights, sheds and quiet corners can give them both food and shelter.

What can you do?

Clear webs when you find them and keep vegetation trimmed away from the house. Check gaps around windows and doors, particularly where you regularly see spider activity.

It also helps to look at the insect population around the property. If there are plenty of insects, there is a reason for spiders to stay.

If spider activity keeps coming back, professional Pest Control in Melbourne can help identify what is supporting the problem.

4. Mice

Mice can be surprisingly difficult to locate. You may hear scratching at night without seeing a mouse at all.

They can squeeze through small openings and settle in roof spaces, wall cavities, cupboards, garages and other quiet areas.

Signs to watch for include:

  • Small droppings around food or storage areas
  • Gnaw marks
  • Scratching sounds
  • Nesting material
  • A noticeable smell in enclosed areas

What can you do?

Store food properly and keep rubbish covered. Check for gaps around doors, pipes and other possible entry points.

If you are hearing scratching regularly or finding repeated signs of mice, don’t wait for the problem to become obvious. Rodents can reproduce quickly, and finding where they are getting in is an important part of controlling them.

5. Rats

Rats are more than an unpleasant sight. They can damage property, contaminate food and create problems in areas where people live or work.

They may enter through gaps around buildings, drains or other openings and can settle in roof spaces, garages and outdoor structures.

What can you do?

Keep rubbish bins closed and avoid leaving food waste exposed. Remove clutter around the property and check for gaps that could provide access.

If you suspect rats, avoid relying on traps alone without understanding where the activity is coming from. A proper assessment can help identify access points and areas where rats are moving around.

6. Termites

Termites deserve a different level of attention because you may not know they are there until damage has already occurred.

They feed on timber and can affect parts of a property that are difficult to see. Wooden structures, flooring, door frames and other timber elements can be vulnerable.

Signs can include damaged timber, discarded wings, mud tubes or changes in doors and windows that become difficult to open or close.

What can you do?

Do not disturb suspected termite activity more than necessary. If you think termites may be present, arrange a professional inspection.

Termite control is not simply a matter of spraying the insects you happen to find. The colony and conditions around the property need to be considered.

7. Bed bugs

Bed bugs are small, difficult to spot and very good at hiding.

They can settle around mattresses, bed frames, furniture and other areas where people spend long periods resting. Finding bites does not automatically prove that bed bugs are present, but repeated unexplained bites combined with other signs deserve attention.

What can you do?

Wash bedding and clothing according to the appropriate care instructions and reduce clutter around sleeping areas. Avoid moving infested furniture into other rooms, as this can spread the problem.

If you suspect bed bugs, professional treatment is often the safer option because finding every hiding place can be difficult.

8. Fleas

Fleas are often associated with pets, but they can remain in carpets, soft furnishings and other parts of the home.

You may notice bites around the ankles or see pets scratching more than usual.

What can you do?

Wash pet bedding regularly and vacuum carpets and upholstered areas thoroughly. Speak with your vet about suitable flea treatment for pets.

If fleas continue to appear despite treating the pet and cleaning the house, the infestation may have spread into the wider property and require professional pest treatment.

9. Wasps

Wasps can become a concern when they build nests close to areas used by people.

Nests may be found under eaves, in roof spaces, sheds or other sheltered parts of a property. Trying to remove an active nest yourself can result in multiple stings.

What can you do?

Keep food and rubbish covered, particularly outdoors. If you discover a nest, keep your distance rather than disturbing it.

A pest professional can assess the nest and determine the appropriate way to deal with it.

What attracts household pests?

Although each pest behaves differently, the same household conditions can create problems for several species.

Look around your property for:

  • Uncovered food or rubbish
  • Standing water or leaks
  • Overgrown vegetation
  • Cluttered storage areas
  • Gaps around doors and windows
  • Cracks and other openings
  • Areas that are rarely cleaned or disturbed

You don’t have to make your home completely pest-proof. That isn’t realistic. The aim is to remove the easy opportunities that make your property attractive to pests.

When should you call a pest control professional?

Some pest problems can be handled with better cleaning, storage and a few repairs around the property.

Others keep coming back.

Consider professional Pest Control in Melbourne if:

  • You are seeing pests repeatedly.
  • DIY treatment has not made a lasting difference.
  • You cannot find where the pests are coming from.
  • There are signs of rodents or termites.
  • Pests are getting into roof spaces, wall cavities or other difficult areas.
  • You are concerned about handling a nest or unfamiliar pest yourself.

A technician can look at the property as a whole rather than treating one isolated sighting.
