What are Lawn Grubs?
Lawn grubs are simply leaf eating caterpillars. There are 3 main types you may encounter which are: • Armyworm: These caterpillars are dark green, smooth and hairless, 25 to 300mm long with distinctive stripes along the sides of their body, feeding at night through the growing season. From 1 to 6 generations may occur in the course of a normal growing season. They feed voraciously on the grass blades attacking on various fronts like soldiers (hence the name Armyworm) and sometimes devastating the entire lawn. • Sod Webworm: This particular grub is greyish to tan in colour, about 20mm long and spotted, also feeding at night through the warmer months. From 2 to 5 generations may occur throughout the growing season. The adult moth drops her eggs at random during the night, eggs hatch in one week.
