What are Signs of Grub Damage?

  • Irregular shaped, dead areas in your yard. If you peel your grass back, these areas of lawn will roll back like a carpet.

  • Roots: When you pull back the dead areas, you will notice that the roots of the grass were eaten. 

  • Mole holes: Grubs are a favorite snack of moles. If you notice mole holes or tunnels in your lawn, there's a good chance you have grubs around as well. 

  • Weeds: When grubs eat grass roots, this weakens your grass. Weakened grass has less resistance to weeds.

  • Spongy feeling grass. You will notice a sponge-like texture when you walk on damaged areas of your turf. 

  • Edges: Grubs feed on the edges of the dead areas and work their way into your healthier, greener grass.

Pro tip: To see if you have active grubs pull back a section of grass and you will see what looks like little, white worms. These are your grubs!
