At Westfall’s Lawn and Pest Control, we know how important it is to keep your lawn looking lush and green. But if you’ve noticed dry, patchy areas that seem to spread despite watering, you may have a chinch bug problem. These tiny insects are a major threat to St. Augustine grass, the most common turfgrass in Manatee and Sarasota counties. If left unchecked, they can quickly devastate a healthy lawn.
What Are Chinch Bugs?
Chinch bugs are small, black insects with white wings, measuring about 1/5 of an inch long. While they may seem harmless, they are notorious for damaging lawns by feeding on grass blades and injecting a toxin that causes the grass to turn brown and die.
These pests thrive in hot, dry conditions, making Florida’s summer months their prime time to attack. Because chinch bugs multiply rapidly, a small infestation can become a full-blown lawn disaster in just a few weeks.
Chinch bug damage can often be mistaken for drought stress or fungal disease. Here’s what to look for:
• Irregular Brown Patches – Unlike drought stress, which affects the entire lawn evenly, chinch bug damage appears in scattered, irregular patches.
• Spreading Damage – The patches start small but grow larger as the bugs move outward, killing more grass.
• Live Bugs – If you look closely at the edges of the damaged areas, you may see chinch bugs crawling in the grass.
• Flotation Test – To confirm an infestation, cut both ends off a metal can (like a coffee can), push it a few inches into the soil near the damaged area, fill it with water, and wait a few minutes. If chinch bugs are present, they will float to the surface.
How to Treat Chinch Bugs in Sarasota & Manatee Counties
The most effective way to eliminate chinch bugs is with a professional lawn treatment plan. At Westfall’s Lawn and Pest Control, we use specialized insecticides that target chinch bugs while being safe for your lawn, pets, and family. Our treatments not only eliminate existing infestations but also help prevent future outbreaks.
A healthy lawn is your best defense against chinch bugs. Here’s how to keep your grass strong and resilient:
• Mow at the Right Height – Keep St. Augustine grass at about 3.5 to 4 inches tall. Taller grass provides shade and helps retain moisture, making it less inviting for chinch bugs.
• Water Correctly – Overwatering creates ideal conditions for chinch bugs, while underwatering weakens the lawn. Water deeply but infrequently, about twice a week during dry months.
• Fertilize Wisely – Excess nitrogen encourages chinch bugs, so use a balanced fertilizer and follow recommended application rates.
If you catch an infestation early, you may be able to reduce chinch bug numbers with these methods:
• Diatomaceous Earth – Sprinkling this natural powder on affected areas can help dehydrate and kill chinch bugs.
• Neem Oil – This organic pesticide disrupts chinch bug reproduction and feeding.
• Aeration & Dethatching – Removing thatch (the layer of dead grass and roots) reduces chinch bug hiding spots and improves lawn health.
