If you’ve noticed earthworms wiggling about in your lawn, you should celebrate!
Earthworms and nightcrawlers are considered beneficial insects for lawns, because they help with decomposition of turfgrass thatch and grass clippings. This process helps recycle nutrients and organic matter back into the soil. Tunneling and burrowing caused by the earthworms act as natural aerators. These tunnels help oxygen, light and water to penetrate the root zone allowing for better root growth, therefore healthier grass plants.
