Lawn Insect Control

Chinch bugs, grubs and armyworms. This is the one nobody else in town is qualified to argue with us about.

We treat chinch bugs, grubs and armyworms as part of the yard coverage on our year-round plans. The hard part is not the product, it is the diagnosis: chinch damage looks exactly like drought, and treating the wrong insect at the wrong soil depth wastes the whole application.

Why the Diagnosis Matters More Than the Product

We have been reading North Texas turf since 2016, and that matters here more than on any other service, because the number one cause of a failed lawn insect treatment is misdiagnosis. Brown patches in July could be heat, drought, dollar spot, brown patch, chinch bugs, grubs or armyworms, and four of those seven are not insect problems at all.

A pest company that cannot read turf will sell you an insecticide for a disease. We would rather tell you it is a watering problem and not sell you anything.

The Three Insects That Actually Kill North Texas Lawns

  • Chinch bugs feed on the blade and inject a toxin that blocks water movement, so damage looks like drought. It starts in the hottest, driest strips along driveways and sidewalks and does not recover with more water. Worst in St. Augustine.
  • Grubs are beetle larvae eating roots from below. Turf goes spongy and lifts like loose carpet. Birds and armadillos digging up the lawn is a second sign, because they are after the grubs.
  • Fall armyworms arrive in a moving front and can strip a lawn overnight. If it looked fine yesterday and looks scalped today, go out at dusk and look.

The Two Field Tests You Can Run Yourself

For grubs, the tug test: grab the grass at the edge of a brown patch and pull. Healthy turf resists. Grub-damaged turf lifts with no root resistance. Peel back a square foot and count, and more than five white C-shaped larvae is treatable.

For chinch bugs, the float test: cut the ends out of a coffee can, push it two inches into the soil at a green-to-brown edge, fill it with water and keep it topped up for ten minutes. Chinch bugs float up. Both pests get the full treatment in our pest library: chinch bugs and grubs.

What Does It Cost?

Lawn insects are not sold as a one-off treatment. Whole-yard insect coverage is part of Complete Home Defense at $49.99 to $69.99 a month, and Home Defender includes the applicable lawn treatment out to about 25 feet at $35.99 to $59 a month. Both are year-round, both are priced on the square footage of the house, and neither is a contract.

Depth Is the Whole Game

Chinch bugs live in the thatch at the soil surface, so their treatment targets that layer and works best on turf that is not soaked. Grubs live two to four inches down at the root zone, so their product has to be watered in to reach them, and young grubs in late summer die far more easily than large ones in fall. Apply the right product at the wrong depth or the wrong month and you have paid for nothing.

Lawn Insect Control Questions

My lawn is brown. Is it bugs or heat?

Run the tug test and the float test first, both described above and both free. If the patches do not green back up after a proper watering, stop watering harder and start looking for insects.

Can you fix the damage or just stop it?

We stop the insect. Recovery after that is a turf job: watering, fertility and sometimes resodding the worst patches. We will tell you what it needs.

When are armyworms a risk?

Late summer into fall, usually after a wet stretch. They move fast, so if you see them, call the same day rather than waiting for the next scheduled visit.

Do grubs come back every year?

Not necessarily. Beetle pressure varies year to year. What matters is checking in late summer when grubs are small, rather than discovering them in October when they are large and hard to kill.

Is this the same as the perimeter plan?

They are two halves of the same plan. Home Defender protects the structure and the ring around it from ants, fire ants, spiders and roaches. Complete Home Defense adds the rest of the yard, which is where the turf insects live.
