The Grub Damaged Lawn

Grow Rite Lawn Care and Landscaping has been providing lawn care services since 2000. Over the years we have heard many questions from our customers. One of the most common questions relates to grub damaged lawns. More often than not the question sounds something like this. 

Q: I see insects on my property and now my lawn is dying. What’s happening to my lawn?

A: Insects and grubs are likely damaging the root system of your lawn.

Why Do Grubs Damage Lawns?

White grubs are c-shaped, cream-colored larvae of several species of beetle. They can be found underground and cause damage to your lawn by feeding on your lawns root system. Grubs do most of their damage during late summer and into the early fall, when grubworm populations are at their highest. If nothing is done to prevent grub damage the result may be a spongy, discolored turf that can be easily rolled back like a carpet. If your grubworms are making their home in your lawn you may have additional problems with wildlife. Raccoons, skunks and birds often dig for grubs, causing further damage to your lawn.  

Spot Grubs By Looking For…

  • Brown Patches– As your lawn greens up in spring, keep an eye out for brown patches that never turn green. Those dead patches may be due to grubs feeding that occurred the previous fall. To check, lift a piece of your turf. If grubs are the responsible the dead patch of turf will roll up like a carpet or you’ll be able to pull up the grass and see that it has no roots.
  • Dead Patches- Irregularly shaped dead patches that appear in a regularly watered lawn late in the summer or early in the fall. If grubs are the responsible the dead patch of turf will roll up like a carpet or you’ll be able to pull up the grass and see that it has no roots.
  • Unwanted Animals- Birds, skunks, armadillos, raccoons or moles will tear up your lawn as they hunt for grubs to eat. These animals also dig for earthworms, so confirm grubs are present before pursuing any grub treatment.
  • Spongy Turf- Sometimes you can detect sponginess before extensive brown patches appear. With well-watered lawns sponginess may be the first clue that grubs are present

Treating Grubs

Grubs can be treated by preventative measures taken in the early summer or you can begin treatment as soon as you notice that grubs are damaging your lawn. If you suspect a grub infestation on your property it is best that you contact us for a professional consultation.

Grubs Are Not Going Away

Each season the beetle population is increasing and putting more larvae into the soil. Increased beetle population means more grubs in the soil to ruin your lawn. The Minnesota summer season brings along unwanted critters, insect damage is a common complaint. If you’ve noticed rapid turf discoloration or drought-like symptoms that do not improve with regular watering, then it is best to contact us.  We will prescribe an insect control and maintenance program that is right for your lawn. Insect damage can lead to costly lawns repairs and even total lawn renovation if not addressed in a timely manner. Why wait?
