GRUB CONTROL SUB-SURFACE ROOT
The 2 cycles of Grub damage occurs in the spring as ground temps warm into the 50 to 60 degree range and in the
late summer from the middle of August through November. Continued damage can occur for years if left unattended,
the cost to reseed and the eye sore will always remind you to never let it happen again. If you are capable of
spraying, you will save lots of service fees and also save your landscape investment. Areas that are more heat and
drought stressed will often show symptoms first, These areas are often in full sun, and have a south-facing slope.
Turf that is well-drained, moist, and have high organic matter are especially susceptible. Grub damage is easily
determined by pulling back the sod. If the turf pulls back easily as if to lift pieces of sod, this is often grub
damage. Grubs feed on the roots at the thatch/soil interface, which results in the turf being easily “peeled back”.
Often times the grubs will be present where the sod has been removed. If the soil is dry, digging down a short
distance may reveal the grubs.
