Deposits of mud (worm casts) are found on the surface of lawns, and are particularly noticeable if the turf is of fine quality. Worms are great at improving the condition of the soil by pulling down and incorporating organic matter. The tunnels that they make as they wend their way around, provide perfect aeration and drainage tunnels. The casts can become smeared by lawnmowers and feet, making the turf muddy and slippery. Moss and weeds can also develop on these muddy spots.

Spot them

Earthworm is the common name for the largest members of the Oligochaeta, of which there are about 3,000 types.

worm casts

Comment from laura condron

In the last month or so I have noticed worm casts on my grass. Sometimes it looks like when you are on the beach and you see thos squiggles (sorry for the description!!) in the sand, I am getting that but mud. I recently cleaned up after my dog and when I picked up some soil there were loads of brown worm type creatures, lookd a bit like mealworms but have no idea what they are or how to treat mt lawn to get rid of them. The closest I can find anything that looks like them are leatherbacks. Can you help me at all?
