About a week ago I left the main door of my building and there were LOADS of these wormy/larve all over the tiled floor. The porch area is covered so unlikely that they have blown in, it was as if there had been a huge hatch of them. There is no bin area or anything like that round there so I can't work out where they are coming from? Eventually they seemed to disappear/been eaten by birds/stood on! So I was relieved and thought that was the end of it however I went out yesterday and the same thing had happened again!
I looked online and in books but cant find anything that looks like them? They are about and inch long, quite fat and don’t appear to have any legs as they just roll about on the spot.
I have attached some photos. Could someone help me work out what they are and where they could be coming from!
