When lawn insects make a meal out of your grass, it can be incredibly frustrating. After all, it’s a major barrier standing in your way to a great-looking lawn.
These lawn destroying insects will ultimately wind up killing your grass if they’re not stopped in their tracks. Unfortunately, lawn pest damage often goes unnoticed until it becomes severe. If your grass is suddenly turning brown, you might be wondering whether your lawn has become an all-you-can-eat buffet.
Let’s look at the 3 main culprits that might be causing you problems so that you can answer the question of, “What’s eating my lawn?!”
Grubs, which is the collective name for several species of beetles in the larval stage, are tiny white c-shaped pests that have the potential to do a tremendous amount of damage. That’s because these are bugs that eat grass roots.
Finding one or two grubs in your grass is no reason to panic. However, a large population of grubs can definitely do serious, sometimes irreversible, damage.
Beetles lay their eggs in the summer. Grubs are born in the soil and typically start feeding on the roots of your lawn around mid-August. Unfortunately, damage from these pests can occur rapidly.
How to Get Rid of Lawn Grubs
In terms of how to deal with this pest, prevention is the best solution. Preventative products work by taking care of young grubs as they hatch. Preventative grub control will keep your lawn protected all season.
However, it’s important to note that the timing is essential to its success. Preventative products must be applied before grubs mature as it won’t work effectively on adult pests.
If you’ve missed the timeline for a preventative product and are now dealing with a grub problem in late summer or early fall, a curative product will be needed. Curative grub control products are more costly, which is another reason why focusing on prevention is best.
Of course, any damage that has already been done will need to be addressed. Damaged grass areas will need to be seeded in the fall.
2. Chinch Bugs
Of the lawn destroying insects that might be eating your grass, chinch bugs are another one to watch out for. These pests have blackish gray bodies with fine hairs and white wings. However, since the adult is only about a ⅙ inch long, chances are, you won’t notice those details. What you are sure to notice is their damage (at least when it becomes severe enough).
Chinch bugs use their piercing mouthparts to suck the moisture out of your grass blades. Then, they inject their toxic saliva into the blades that will disrupt water movement within the grass, causing it to die.
Chinch bug damage often occurs in the heart of the summer when these insects are actively feeding. A chinch bug infestation may bring as many as 200 insects per square foot of turfgrass. Both young chinch bugs (called nymphs) and adults feed on grass, making them a serious problem. Unfortunately, the damage is not always noticed until it’s severe. The first sign of a chinch bug problem is usually yellowed grass, which occurs as these pests suck the plant fluids from it.
Oftentimes, it is damage that alerts homeowners to a potential chinch bug problem. If you have a lawn that is changing colors, lawn insects are certainly one potential culprit.
Start by performing a visual inspection. This should be performed on the fringe of where the grass is still green because chinch bugs will move out once they’ve consumed an entire area. You’ll need to get down close to the grass and pull the thatch layer apart at various areas. Watch closely for movement for at least a half a minute.
Another way to scout chinch bugs is flooding a small area with a metal tube. This could even be a metal coffee can with the top and bottom removed. Insert this into the ground one or two inches deep and fill it with water. Chinch bugs will float to the top. Give it 10 minutes and then count the number of pests in order to determine a population density for your chinch bug problem.

Removing excess thatch and having lawn aeration performed will help break up compacted soil and remove the favorable environment where chinch bugs prefer to live. However, if you’re already dealing with an infestation, then an application of a curative product will likely also be necessary.
3. Sod Webworms
Also referred to as “lawn moths,” sod webworms are another destructive lawn pest that might be causing you trouble. Adult sod webworms are dull-colored moths that can reach a ¾ inch in size. The adult is characterized by a pair of projections on its head, resembling a snout. However, it is the sod webworm larvae that you need to worry about.
Sod webworms overwinter as mature larvae in silken tunnels that they have constructed. They will begin feeding in the spring, at which time damage may not be noticeable. Sod webworm larvae feed at night on grass leaves and stems near the soil surface.
The most serious damage generally occurs in July and August as the webworms grow (and the damage becomes more severe). Larval damage is often observed as brown patches up to the size of a baseball. These brown patches may include puncture holes where birds have searched for a webworm meal.
If you suspect sod webworm damage, examine your grass for their silken tunnels. You can also sample for the larvae by using a soap disclosing solution (soapy water) that irritates the body of the insect and then forces the insect to the surface of the turfgrass.

If you have an infestation of sod webworms, then you’ll require a control product that will suppress larval populations while they are actively feeding. Going forward, using a preventative product each year (at the time when they are likely to feed) will keep these destructive lawn insects away.
Is it Lawn Insects or Something Else?
If you’re experiencing some of the problems we’ve described above with your lawn, then there’s certainly a good chance that you have lawn destroying insects on your property. Maybe you’ve even scouted the lawn, as we’ve explained how to do, and you’ve spotted these pests with your own eyes.
Even so, it’s important that we mention that there are sometimes more than one issue at play. While you certainly might have a lawn insect problem, you might also have something else going on at the same time. And if you haven’t scouted these insects, you could potentially have something else (entirely different) happening.
For instance, a lawn that is changing colors and browning could also be experiencing disease or drought. The point is, a proper diagnosis is really important when it comes to the right course of treatment.
