Australians are no strangers to odd creepy-crawlies making an unwelcome appearance in their homes.

However, on the very streets Aussies walk on lies a hidden network that could be ushering in a more insidious invader.


Pest control experts have warned homeowners about 'cockroach highways' that could infiltrate homes.

These pathways are from underground sewage tunnels that crisscross beneath cities, and they give cockroaches direct routes into homes.

Last week, pest control specialist Christopher Moschella visited a property in Rockdale after the homeowner reported a significant cockroach problem.


Cockroaches aren't just a nuisance; they are also a health hazard.

They carry a high level of bacteria on their bodies, and their journey through sewers poses significant health risks.

Christopher then found an access point to these subterranean passages in the homeowner's backyard, teeming with cockroaches.


Christopher showed footage of a pit swarmed with these pests, which also 'reeked' of cockroaches' smell.

However, it's not just Sydney that's affected; most major cities are also grappling with similar challenges.

While Aussies might not be able to do much about the location of these tunnels, understanding the risk they pose is crucial.

Christopher warned that 'there's almost a 100 per cent chance you're going to see cockroaches all the time,', especially for homes near these access points.

Homeowners cannot poison the pits directly, as it could contaminate waterways.

However, there are steps homeowners can take to protect their homes from swarms of cockroaches.


Standard pest control treatments available from hardware stores could create a barrier that kills cockroaches as they enter.

To keep these unwelcome guests at bay, Christopher also recommended general pest control treatments every six months to a year.

This regular maintenance could keep homes cockroach-free until the next pest control treatment.

Senior homeowners who want to keep their homes pest-free should inspect their property for any potential access points to these 'cockroach highways'.

If you're dealing with an infestation or want to prevent one, consider sealing these 'cockroach highways' and schedule a professional pest control treatment.

Keep an eye out for signs of cockroaches and act swiftly to protect your home and health.
