You have probably seen 100s of Millipedes in the last couple of days in your garden and your home in Melbourne. Just after the first heavy rains in Autumn after a long dry Summer, they will be on the move. They will come inside under doors and through cracks as they are attracted to light. They generally live in and feed on organic material such as leaf litter and mulches in the garden. When disturbed they deposit a yellow stinky substance to deter predators. They don’t do much harm other than being annoying. You can try putting down a barrier spray or sticky tape on the bottom of doorways to deter them from coming indoors.
