Can you treat for grubs in the late fall?
Treating in late summer or early fall is ideal, as that is when the smaller, young grubs are most susceptible to nematodes.

The site gives no recommendation for mixing straight fertilizer and GrubEx, so it may be wisest to apply one product at a time.
Why are there grubs in my lawn in August?
Adequate moisture in mid-summer will favor beetle activity and grub development. If plentiful rainfall or irrigation continues through August and September (when grubs are actively feeding) damage may not be noticeable because the grass continues to grow and masks the root injury symptoms.
When should I spray my lawn for grubs in July?
Use them in June or July to control grubs that would be damaging turf in the fall. Applying them now will allow some of the chemical to leach through the turf or break down to the point that not enough insecticide will be there in July to control grubs.
How long do grubs stay in your lawn in winter?
They spend the winter as large grubs (0.75 inches long) some 2-6 inches below the soil surface. When the ground warms up in spring, they resume feeding and can cause damage from the time the grass turns green until they pupate in mid-May. Grub damage may appear in home lawns from mid-September to November or from March to early May.
