Chinch Bugs and Hunting Billbugs: The Memphis Lawn Pests That Look Like Drought

You've been watering. You've been mowing right. And yet patches of your lawn keep turning brown and spreading no matter what you do. Before you crank up the sprinklers again, consider that you might not have a watering problem at all. You might have a pest problem.
Over the past few years, Memphis and the surrounding Mid-South have seen a rise in two turf-damaging insects that masquerade as drought stress: chinch bugs and hunting billbugs. Both quietly kill warm-season grass, and both get misdiagnosed until the damage is widespread.
Know the Culprits
Chinch bugs are tiny at about one-sixth of an inch. Adults are black with white wings; the younger nymphs are bright orange-red. They thrive in the hottest, sunniest, most drought-stressed parts of a lawn and go after Bermuda and Zoysia. They pierce the grass and suck out the sap, then march outward into healthy turf as each patch dies.
Hunting billbugs are dark, reddish-brown weevils less than half an inch long, with a long curved snout. The adults chew at the crown where the grass meets the soil, but the real damage comes from the larvae: small, legless grubs that hollow out the stems from the inside. Because so much happens inside the plant, billbugs are one of the most misdiagnosed lawn problems in the Mid-South.
Two Quick Tests Before You Blame the Weather
Check the border. Where brown grass meets green, part the turf and look closely. Chinch bugs gather right at that edge, so if you see tiny black-and-white insects, that's your answer.
Do the tug test. Grab the grass at the edge of a dead patch and pull. If it pops off easily at the crown and the broken ends look packed with sawdust, that's billbug damage. Healthy, just-thirsty grass holds firm.
If your lawn is browning in the hottest, sunniest spots and more water isn't fixing it — stop watering and start scouting. Water won't cure a bug problem, and overwatering invites fungus on top of it.
How We Treat It
Because both pests damage turf in a similar way, the control strategy is similar too. Our approach combines contact and systemic insecticide applications in late spring and early fall, smart irrigation to keep the lawn healthy, and controlled-release fertilizer to push new growth. The goal is a lawn strong enough to resist the next wave.
If you've got spreading brown patches that more water won't fix, let us take a look. We've been telling thirsty lawns apart from infested ones across the Mid-South since 1987.
