The Effects of Grubs in a Lawn
Scarab Beetle Grub Effects

The treatment edge for covered chafer and Japanese scarab grubs is 8 to 10 grubs for every square foot, for May/June creepy-crawly grubs 3 to 5 grubs for each square foot, and for the little ataenius grubs 30 to 50 grubs for each square foot. One billbug grub for each square foot of yard is viewed as adequate for beginning treatment.
