Early Fall Grub Information

Grubs can cause severe damage to turfgrass in Maryland. They are the larvae of several species of beetles but the most common here in Maryland is the Japanese Beetle grub. Their life cycle takes one year to complete. The beetles emerge from the soil in late June/early July and feed on trees and shrubs. During July and into early August, they mate and lay eggs in the soil. The eggs hatch in August and begin feeding on turfgrass roots, especially when there is adequate soil moisture.

Most grub damage occurs in September and early October. The optimal time to prevent grubs is from late April through mid-July. Curative treatments in August through October are less effective and require immediate irrigation for effective results.
