Have you noticed millipedes in your house recently?
In Adelaide, millipedes (most commonly the invasive Portuguese millipede) migrate into homes during late autumn and winter seeking warmth, shelter, and a mate. The cold, wet winter weather makes the outdoors unfavorable, and these critters are also highly attracted to interior lights shining out into the night.
How to keep them out.
Apply a residual pesticide (e.g., products containing bifenthrin or fipronil) about 1 meter out and 1 meter up around your home’s foundation and entry points.
Do not squash them. They don't bite, but when squashed, they release an unpleasant, foul-smelling, and yellowish-brown liquid that can stain carpets, tiles, clothing, and skin. Just vacuum them up or pick them up with a tissue and dispose.
