When I walk in my grass, especially in the evening, little moths(?)fly up out of the grass. Should I be concerned? Do I need to do something about them?

The lawn moths you are seeing are not damaging your lawn but if they lay eggs and the eggs hatch into larvae (called sod webworms), their feeding can cause damage to the roots of your lawn. If you begin to see damage you can treat your lawn to kill off the larvae. The bacterium Bacillus thuringiensis, or BT is registered for sod webworm management. It's readily available in garden centers. Be sure to apply according to label directions.
