Is Wagga in a mouse plague right now?

We can't say. Plagues rise and fall with the seasons, and the most recent CSIRO statement in our sources dates from May 2021. What's happening in your house matters more: droppings, gnawing and nibbled grain.

Can I sort out German cockroaches myself?

Keeping crumbs, grease and cardboard under control helps any treatment work. They hide inside appliances and the joins of cupboards, which makes them hard to reach. We'd call a pest business and ask which product they'll use and how many visits to expect.

Do you cover Junee and the villages?

Yes. Give us your postcode with what you've seen.

Pest control Wagga Wagga: mice, cockroaches and wasps

What's different in Wagga

European wasps across the Riverina

The Australian Museum says European wasps are found in Wagga, Junee, Narrandera and Griffith. Their nests are usually hidden in the ground or a wall cavity, so you notice the traffic before the nest.

Ross River at the Botanic Gardens

NSW Health found Ross River virus in mosquitoes trapped at the Wagga Wagga Botanical Gardens on 28 January 2025. As at 30 July 2026, it also lists Wagga Wagga as a Japanese encephalitis high risk area. Both are NSW Health matters, and its advice on bites is the one to follow.

Water on the plains

Inland NSW mosquito numbers are driven by rainfall and irrigation, NSW Health says. In the 2024 to 2025 season Culex annulirostris was the most abundant inland mosquito over summer.

Fire ants

A suspected fire ant anywhere in the state is a report to the NSW Biosecurity Helpline, never a treatment.

Mice after a good season

House mouse numbers can climb to plague levels. The Australian Museum says they seem to rise after rainfall and about 18 months after a fire, and in May 2021 CSIRO said favourable conditions had pushed numbers up in parts of NSW and Queensland.

CSIRO also says mice can breed from about six weeks old, every 19 to 21 days. That's why a few droppings in the shed in autumn are worth acting on before winter, when the cold drives them inside.

Small cockroaches in the kitchen

Amber cockroaches about 12 to 15 mm long with two dark stripes running lengthways are German cockroaches. They live in kitchens, under sinks and inside cupboards and appliances, and often arrive as stowaways in cardboard boxes.

The Australian Museum calls the German cockroach the hardest pest cockroach to get rid of, and seeing them out during the day usually means a large population. The big brown cockroaches that wander in from outside are a different job, so tell the pest business which kind you're seeing. The cockroach control page explains the difference.

Before the cold sets in

Fill gaps around pipes, cables and under doors: Victoria's Department of Health says mice gnaw holes up to 20 mm wide.
Keep pet food, chook feed and grain in sealed metal or hard plastic bins.
Get flattened cardboard boxes out of the kitchen and laundry.
Wipe benches at night and don't leave pet bowls out.
Tip out water from pot plant bases, tyres and buckets each week.

If it were our house in Wagga Wagga

We'd deal with mice the first week we saw droppings in autumn rather than waiting for winter, and we'd bring in a pest business early for German cockroaches instead of buying spray after spray. Tap what you've seen and your postcode.
