What would one recommend to pretreat my lawn with for the prevention of grub worms?
Thanks, Robert Doesn’t work that way – you can’t pretreat for an insect problem which may or may not exist. Keep your lawn in good health and avoid over fertilizing and over watering, both of which create environments conducive to grubs. Monitor during the growing season and if grubs are detected in sufficient populations, treat with a biocontrol like milky spore or nematodes.
