During the fall, they start digging deeper into the soil and stay there all winter. As the soil starts to warm up in the spring, they return to the surface with a voracious appetite. The second year of their life-cycle is the most destructive part of their life-cycle. Your lawn has grubs n various stages of their life-cycle.
