If perfect turf is your goal, use Grass Pad recommended two-step white grub solution. The first line of defense against white grubs is to apply systemic Long Lasting Grub Contol, in mid-June to early-July. Long Lasting Grub Control gives greater flexibility in timing and continuous protection. The second line of protection is an application of Quick Kill Grub Control in mid-August while white grubs are at their most vulnerable life stage. Quick Kill Grub Control kills by contact and when applied will stop grubs in 72 hours.
White grubs can be one of the most damaging insects to your turf and unfortunately, the better the turf, the more likely the grubs are to attack.
Grubs are the larval stage of several large beetles – June Bugs, May Beetles, Masked Chafer Beetles and Japanese Beetles. The grubs feed on the roots of your lawn and can kill large sections in a very short amount of time.
While some grubs reproduce on a three-year cycle, the annual white grubs that reproduces on a one-year cycle do the most damage here in the Mid-West.
Most folks first spot grubs while planting their spring flowers and gardens in late April or May, just before the time the grubs will pupate and change into the adult beetle. They don’t do excessive damage during this period.
When adult beetles emerge in late May or June, they will be most noticeable around street lamps, porch lights, patio screens and pool skimmers. At this point, beetles will mate and lay eggs in the most attractive lawn they can find. Eggs will hatch weeks later, and young grubs begin feeding voraciously, on grass roots. Grubs continue to grow and consume larger amounts of roots. Visible grub damage may not appear until September or October.
Grub damage can occur from August through October. Identification of grub damage can be tricky as it occurs when lawns can be stressed by summer drought or lawn disease. Grub damage is the most severe when turf is dry or under stress from lack of proper fertilization.
The best way to check for grub damage is to grab a handful of the affected turf and gently tug. The grass will peel back like a carpet, exposing the grubs that have eaten the roots. Grubs are often discovered after turf has been disturbed by foraging skunks and raccoons. In these cases of visible signs of grub damage, an application of Grass Pad recommended Quick Kill will stop grubs in 72 hours. LoveLand Renovator fertilizer and an aggressive watering regime can help reduce the amount of damage that occurs. A thorough, fall renovating will be necessary to complete the repair process.
