How to Spot Chinch Bug Damage and Kill Chinch Bugs in Your Lawn
Summary
If your grass is looking rough and you’re not sure why, chinch bugs might be the culprits. In this post, I’ll walk you through how to spot chinch bug damage, figure out if they’re really the problem, and what you can do to get rid of them—plus a few tips to help your lawn bounce back. Let’s get your yard looking green and healthy again!
The Usual Suspects: What Are Chinch Bugs?
Alright, folks, let’s talk about one of the most common summertime headaches for Houston lawns—chinch bugs. These little pests love the heat and dry weather, and they can turn a beautiful St. Augustine lawn into a patchy mess before you know it.
How to Spot Chinch Bug Damage
So, how do you know if chinch bugs are causing trouble in your yard? The first thing you’ll notice is what looks like a “hot spot” in your grass. It’s usually right where the concrete meets the lawn—think sidewalks and driveways. Those areas heat up fast, and chinch bugs are drawn to the stressed-out grass there.
The damage starts out looking like drought stress: the grass turns yellow, then brown, and eventually dies off. If you’re watering like you should and still seeing these dead patches, it’s time to get suspicious.
Getting Down to the Root: Confirming Chinch Bugs
Now, don’t just assume it’s chinch bugs—let’s make sure. Get down on your hands and knees at the edge of the damaged area (not the middle, that’s usually already dead). Part the grass and look real close. You’re searching for tiny black bugs that look a bit like gnats. The adults have a little white “X” on their backs—pretty distinctive once you know what to look for.
Time to Take Action: Treating with Cyonara
Alright, you’ve found chinch bugs—now what? My go-to is Cyonara, which you can pick up at our office in Arcola. It comes in a bottle that attaches right to your hose. Start in the far corner of your yard and walk backwards, fanning the spray back and forth to cover the area. You’ll probably need to do this a couple of times, about five days apart, to make sure you get them all.
Liquids like Cyonara work fast, which is what you want. Granular products just don’t give you that instant knockdown.
Prevention and Recovery Tips
The best way to keep chinch bugs away is to keep your lawn healthy and well-watered. They love drought-stressed grass, so make sure your sprinkler is covering every inch of your yard. If you do get hit, act fast—chinch bugs can kill St. Augustine grass for good, and you might end up with Bermuda grass taking over those bare spots.
If you catch the problem early and treat it right away, your lawn has a good shot at recovering. But if the damage is already done, you may need to replace some patches.
Final Thoughts
Chinch bugs are a pain, but with a little vigilance and the right treatment, you can keep your lawn looking great all summer long. Walk your yard, keep an eye out for trouble, and don’t be afraid to get down in the grass and investigate.

FAQs
How do I know if it’s chinch bugs or just drought?
Great question! Chinch bug damage looks a lot like drought stress, but if you’re watering regularly and still seeing dead patches—especially near concrete or in sunny spots—chinch bugs are a likely suspect. Get down and look for those little black bugs with the white “X” on their backs to be sure.
Can chinch bugs kill my whole lawn?
Unfortunately, yes. If you don’t catch them early, chinch bugs can wipe out big sections of St. Augustine grass. The dead areas usually don’t come back, and you might end up with Bermuda grass taking over. That’s why it’s so important to act fast!
How often should I treat my lawn for chinch bugs?
If you find chinch bugs, treat the area right away with a product like Cyonara. You’ll probably need to spray again about five days later to catch any stragglers. There’s no need to treat preventatively unless you’ve had problems before—just keep your lawn healthy and keep an eye out.
Is Cyonara safe for pets and kids?
Once Cyonara has dried on the grass, it’s generally safe for pets and kids to go back on the lawn. Always follow the label instructions and keep everyone off the treated area until it’s completely dry.
Can I use something besides Cyonara?
Absolutely! There are other products out there that will kill chinch bugs—just make sure whatever you use lists chinch bugs on the label. I like the hose-end liquids because they’re easy and work fast, but granular products can work too (they just take a little longer).
Will my grass grow back after chinch bug damage?
If you catch the problem early, your grass might recover on its own. But if the area is totally dead, you’ll probably need to re-sod those spots. The sooner you treat, the better your chances of saving your lawn!
How can I prevent chinch bugs in the future?
The best prevention is a healthy, well-watered lawn. Chinch bugs love stressed, dry grass, so make sure your sprinkler is hitting every part of your yard. Walk your lawn regularly and jump on any problems as soon as you spot them.
