Identifying Lawn Pests vs. Another LawnProblem 

Lawn pests can wreak havoc on your grass, but so can otherfactors like too much or too little water, poor soil quality, or even mowingtoo short. You can start by looking for signs of lawn pest damage to rule outother causes. 

General signs that you have lawn pests include:

  • Visible insects: You may see actual pests near the soil level or emerging from the     ground. Look for C-shaped grubs in the dirt, caterpillars above the     surface, or tiny chinch bugs. If you see any unusual insects on your lawn,     it's worth taking a photo and contacting a professional for help     identifying them. 
  • Increased bird or animal activity: You can also keep an eye out for increased     bird activity in your lawn. You might see birds pulling worms or other     bugs from the ground. Moles, raccoons, and skunks also feed on lawn pests     and might dig up your lawn to access them, increasing the damage. 
  • Spongy turf: If you have noticed that areas of your lawn feel spongy when     walking on them, this is often a tell-tale sign of insect damage. 
  • Irregular brown patches: Your lawn may develop brown patches from     inconsistent watering or scorching in certain areas. But if you notice     brown or dead spots in irregular shapes, these could be due to a pest     infestation. 

If you're following maintenance tips and still notice signs of distress, you may have lawnpests. 

Signs of Common Types of Lawn Pests 

Along with knowing the general signs of lawn pests, it canbe helpful to understand the specific indicators of some of the most commonpests. 

  • Grub worms: Grub worms, or "grubs," are white beetles with C-shaped     larvae. They feed on grass roots below the surface of the soil. You might     notice signs like wilted grass blades that eventually turn brown and die,     or you can try peeling back the turf to see if it peels easily and look     for grubs underneath. 
  • Chinch bugs: These are sap-sucking bugs that lay eggs in the grass,     reproducing quickly. They cause the turf to take on a purple tint, then     eventually wilt and turn brown. Chinch bugs create dry-looking patches of     grass, which can often be mistaken for drought stress. 
  • Sod webworms: These lawn pests are the larvae of the sod webworm moth. The     larva is about one inch long with a green or brown color and dark     spotting. Meanwhile, the moths are a grayish tan color. 
  • Billbugs: These larvae have reddish-brown heads and look similar to white     grubs, but they have smaller legs. Billbug damage leads to grass that you     can pull out of the ground easily and grass stems that have been hollowed     out. 
  • Armyworms: Armyworms are between one and two inches long and can be gray,     pink, or yellow in appearance. They eat grass blades and stems, along with     other plants. Their invasions create circular bare spots in the     grass.

How To Identify Common Lawn Pests

If your lawn is looking thin, brown, or unhealthy, lawn pests may be the cause. While issues like improper watering, poor soil, or mowing too short can damage grass, insects often create distinct signs you can spot. You may notice visible insects such as C-shaped grubs in the soil, caterpillars on the surface, or tiny chinch bugs near the base of your grass. Increased bird, mole, raccoon, or skunk activity can also signal pests beneath the surface. If your lawn feels spongy when you walk on it or develops irregular brown patches that don’t improve with watering, insects could be damaging the roots. Different pests leave different clues. Grubs feed on grass roots and cause turf to peel up easily. Chinch bugs suck sap from grass blades, creating dry, brown patches that resemble drought stress. Sod webworms chew grass blades, while billbugs hollow out stems and make grass easy to pull from the soil. Armyworms feed aggressively on grass blades and can create circular bare spots. Identifying the problem is the first step, but proper treatment and prevention are essential to restore your lawn’s healthy, green appearance. Professional lawn care can help you accurately diagnose pest issues and apply the right treatment to protect your yard long-term.

How to Spot If Your Lawn Is Getting Too Much Water

If your lawn is getting too much water, you’ll start to notice clear warning signs. You might see puddles that don’t drain, feel soggy ground under your feet, or notice more weeds thriving in the damp conditions. Your grass may even turn yellow as excess water suffocates the roots, and in worse cases, dead patches can appear due to fungal disease. To keep your lawn healthy, you should water early in the morning, focus on deeper but less frequent watering, aerate the soil to prevent compaction, avoid cutting the grass too short, and remove weeds quickly. By paying attention to these signs and adjusting how you care for your yard, you can maintain the right balance of moisture and keep your grass strong and vibrant.

When To Stop Watering Your Lawn

Proper lawn watering is essential for maintaining healthy, green grass—but knowing when to stop watering your lawn is just as important as knowing when to start. Overwatering can lead to yellowing grass, fungal diseases, pests, and wasted water. Tatum Lawn Care LLC, serving Moses Lake, recommends adjusting your watering schedule based on weather, soil conditions, and seasonal changes. You should pause watering when rainfall has already provided sufficient moisture, as watering during rainy periods can cause weed growth and lawn disease. If your lawn is showing signs of fungus or pest infestations, excess water can make the problem worse—professional treatment and controlled watering are key. Soil type also matters: sandy soil drains quickly and may need more frequent watering, while clay or loamy soil retains moisture and is more prone to overwatering. As fall approaches, continue watering only as long as the ground remains unfrozen. Once nighttime temperatures stay below 50°F or the first hard frost hits, it’s time to stop watering for the season. Watering frozen soil won’t benefit your grass and can damage your lawn. For expert lawn care, irrigation services, and seasonal watering guidance in Moses Lake, trust Tatum Lawn Care LLC.
