Controlling habitat, encouraging natural enemies and predators,
and pursuing treatment schedules are ways to kill grubs. An
aerated, shaded lawn whose irrigation timetable is set at 1 inch
(2.54 centimeters) weekly discourages grubs, whose preference is
for buzz-cut, compacted, moist surfaces. Birds, milky
spore-carrying bacteria, parasitic nematodes and wasps, and pet
amphibians and mammals number among a grub's food chain enemies and
predators whereas chlorantraniliprole-, halofenozide-,
imidacloprid-, and trichlorfon-active sprays work chemically and
diatomaceous earth, insecticidal soap, and neem oil work
organically.
