European Chafer
Rhizotrogus majalis
European chafers are common pests of turf in the northeastern U.S. and parts of the northern Midwest where they are more damaging than Japanese beetles. Their larvae (grubs) feed on all types of grasses; however, they may move into vegetable plantings when populations are high.
Damage occurs as a result of two things: grubs feeding on roots and animals feeding on grubs. If grub feeding coincides with dry conditions, damage to turf can be severe as the grass cannot replace injured roots. This can lead to large patches of browning or even lawn death. As stated earlier, grubs encourage animals like skunks and raccoons to uproot patches of turf, peel back sod and leave behind unsightly messes.
Controlling European Chafers: Control begins in spring when grubs becomes active and continues through the summer season.
- Apply Hb NemaSeek beneficial nematodes after the last frost date to target grubs. Applications can be repeated in early fall to reduce overwintering populations.
- Frequent irrigation in late June can deter female European chafers from laying eggs.
- Fall irrigation can also increase the turf's ability to tolerate the grub's root pruning.
