Grub Worms

Grub WormDespite their names, grub worms are actually the larvae of a few different kinds of beetles. Depending on the region you live in, this would include Japanese beetles, European chafers, and June bugs. Indeed, grub worms are not actually a single species, but rather a common term for beetle larvae that damage grass by feeding on its roots. 

Grub worms typically hatch in the summer, and they reside largely beneath the surface of a yard’s soil. As they grow, they subsist mainly on roots, which is what makes them problematic. While the adult forms of these insects might be harmless (if not a bit annoying at times), it’s the larvae that threaten the health of a lush green turf. 

Dry PatchWith fat, C-shaped bodies that are typically milky in color and around 1-2 inches long, hungry grub worms will create dry patches in your lawn. Large, amorphous expanses of dying grass that don’t respond well to watering, overseeding, etc. are a fairly sure sign of grub worms.

The trick is, other pests- such as chinch worms- can cause a similar pattern in affected grass, so it is important to know how to determine what you are dealing with. If 5 or more grub worms are identified in a square foot of lawn (dug up for inspection), then it is time to take action.
