I have thousands of small thin worms stuck to my outdoor windows, walls, and pavers. They are all dead. They are all in one corner of my house. I have never seen them alive. We clean then off and then they just come back. There is a downpipe nearby, if that is relevant. I would like to get rid of the worms but do not want to kill any of the plants in the same area. The dead worms are mainly straight, few are curled up. The worms are a bit brown, red, see through with what looks like black food through the centre of the worm. They do not have legs. I live in Australia and the downpipe mentioned above is connected to guttering. I am not sure if the worms appear after rain, I have only seen one alive.
