How do I control grubs?
Grubs are the larval stage of beetles. Problems arise when the grubs consume more roots than the plant can naturally regenerate.
Since most grubs feed primarily in the spring and early fall, that is the time to attack them with insecticides such as Sevin and Dylox. Another insecticide, Merit, will prevent grubs from doing any damage when they hatch in late summer. However, Merit must be applied in July before the eggs hatch; it has little to no effect on mature grubs. Continue to apply Merit each July. Be sure to follow the manufacturer’s instructions when using pesticides.
