Portuguese millipedes are an invasive pest that were accidentally brought into Australia in the 1950s. Since then, they have spread across much of the country. Because they have no natural predators here, their numbers grow quickly—especially during cool, damp weather. When conditions are right, large groups can suddenly appear around homes, gardens and outdoor areas.
Although Portuguese millipedes are not dangerous to people, they can be a major nuisance. They often crawl into houses in large numbers, especially at night or after rain. Crushing them is not recommended, as they release hydrogen cyanide when squashed. This chemical has a strong smell, can irritate the eyes and skin, and may leave permanent stains on surfaces.
These pests have caused issues in unexpected places too. In one incident in Clarkson, a group of millipedes on the tracks was linked to a train slipping accident, showing how serious infestations can become.
