Grubs are one of the sneakiest pests lurking in our lawns. You likely won’t see them above the surface, but you’ll certainly take notice of the damage they cause. They are a huge problem for thousands of homeowners across Michigan. Many people think it’s not something their lawn needs. You might even be in that camp if you’ve never had a problem with grubs before. However, if you’ve got stubborn brown spots that won’t go away, you might have grubs to blame.

Why Grub Control Could Clear Up Those Brown Spotsgrub damaged lawn

If you take good care of your yard, you might think you can exempt yourself from grub control. However, grubs are actually attracted to healthy lawns because that means a regular source of food. As we’ll discuss in a bit, the term “grubs” is the common word we use to describe the larvae of Japanese beetles. They look nothing like their parents, which is one of the reasons you may not realize you have a problem. Adult Japanese beetles look like, well, beetles! You might see them in your yard, but if you don’t see the white caterpillar-like larvae, what we in the lawn care industry call grubs, you might not make the connection. Adult Japanese beetles are between 1/3 and 1/2 inch in length with metallic-green heads and thoraxes and copper-colored wing covers. Parts of their body also have small whitish hairs.

How Grubs Grow

When adult Japanese beetles lay their eggs, they seek out a healthy turfgrass. Once the eggs hatch, they will grow into C-shaped caterpillar-like bugs with brown heads and white bodies – the characteristic grubs we all love to hate. They will eat the grassroots for their primary food source until they reach adulthood, when they begin eating the grass from the surface above. Once they reach maturity, they emerge from the soil, looking like a garden variety beetle. In fact, grubs are reaching maturity right now and will remain active through September.

As adults, Japanese beetles will switch up their meal choice. Instead of munching on the roots, they will eat the blades of grass, and as they do so, the grass will emit an odor produced when it is under duress. This odor lets other Japanese beetles nearby know that there’s good eating on your lawn! More beetles will arrive, lay their eggs that will become grubs, and the cycle starts all over again. You can see why ignoring a grub problem and waiting to get grub control will make the situation worse. If you haven’t already opted for grub control this year, it’s still not too late! Go Green can rid your lawn of reproducing adults and make sure their offspring don’t make it to spring.

How To Tell If You Have Grubs

Do You Notice More Wild Animals?

When grubs are in abundance beneath your soil, you may notice possums, raccoons, birds, or other wild animals in your yard, more so than usual. That’s because these animals love to eat grubs! Unfortunately, the only way to reach the grubs is to dig into your turfgrass. Animals have no regard for the appearance of your lawn or how hard you work to keep your lawn healthy. They’ll leave your grass in tatters and move on. This is a common problem we see in lawns with extensive grub issues. Fortunately, Go Green can help repair the damage, but the best way to prevent the damage is to get rid of the grubs that brought critters to your lawn in the first place.

Can You Peel Back Your Turf?

If your turf can be peeled back like freshly laid sod, that’s a major red flag in the grub department. If you can do this, you should be able to see some grubs when you roll back the turf. This happens because they damage the turfgrass roots. When those roots are damaged, they can no longer cling to the soil.

Is It Harder To Mow The Lawn?

A healthy lawn should be relatively smooth, and the lawnmower should glide across it – no problem. When you’ve got grubs, their activity can create divets, bumps, uneven areas, or craters. Spongy grass is another problem. Healthy, hydrated grass should be soft, but if your turf feels like you’re walking on an exercise mat, it may be caused by grubs. All those uneven areas can lead to puddling water, which brings a whole slew of other problems like diseases and pests. When your lawn doesn’t drain easily and is littered with holes and bumps, mowing the lawn becomes a headache.

Do You Have A Brown Spot(s) That Won’t Go Away?

When turfgrass loses its root system, it turns brown and begins to die off. When you see a brown patch, you might think it just needs more fertilizer or water. It’s a common tragedy of grub damage. Homeowners don’t realize they’re dealing with grubs, so they try many other remedies first. And all the while, the grubs are continuing to damage the lawns.
