Meteorologists say the combination of a dry winter and humid summer will create the perfect conditions for cockroaches to thrive, with millions of the insects expected to settle in Australian properties over the coming weeks.

Cockroaches are attracted to moist environments, meaning kitchens and bathrooms are usually at the top of their hit list.

Australians are advised to fix any leaking pipes and take extra care when wiping surfaces to minimise the risk of homing unwanted guests.

The recent bushfire crisis and widespread drought has also influenced the roaches to migrate indoors.

According to 7 News, Queensland currently bears the brunt of the cockroach crisis - although Sydney in New South Wales has also seen an influx of the insects between January and March.

The Pest Company says homeowners should remember that just because cockroaches aren't visible, doesn't mean they're not lurking.

"We don't know many homeowners that can see through walls, but we know many cockroaches that love to live in these areas," the company says on its site.

The business recommends caulking up crevices in residential and commercial properties to help limit hiding spots in kitchens and bathrooms.
