If you’re frustrated by the challenges of lawn care in Oklahoma, you’re not alone. With insects, diseases, watering, mowing, weeding, fertilizing and species selection, it can be a challenge to actually sit and enjoy a beautiful turf. This time of the year, some of the most unwelcome visitors to lawns are grubs.
What are grubs?
Grubs are nothing more than the larval stage of several different beetles. The most common grubs to damage Oklahoma lawns are the larvae of June bugs. Damage might start out as small, thin areas of dying turf, but often grow into large, irregular sections of spongy soil and dead sod. The patches are most commonly seen in late spring, late summer and early fall, after grubs eat and destroy the grass roots.
How do I know if I have grubs?
It can be difficult to distinguish grub damage from drought damage in hot summer months because both will appear as yellow or brown patches in an otherwise green lawn. Often, the best clue to alert a homeowner of grub damage is the sponginess of the soil – a hollow feeling when walking on the lawn. If your lawn is properly watered but still feels spongy, try pulling up a section of the sod. If grubs are present, you should be able to peel it up like carpet and see the white, c-shaped larvae feeding on your soil. Grubs love thick, flourishing grass and are very common around tree trunks.
Why are grubs killing my grass?
Certain beetles, including June bugs, lay eggs every year. The optimal environment for their eggs to flourish is thick, moist grass with healthy soil. When these eggs become larvae, or grubs, they need organic matter to feed on. The roots of your grass are grubs’ favorite food. A diet of grassroots help the larvae grow into adult beetles that will eventually lay eggs and start the cycle all over again.
Beetle larvae can destroy large sections of grass roots in a very short time period, often causing significant damage to your lawn before you can even notice, much less prevent, the grubs from taking hold. That’s why professional lawn treatment is key.
How do I get rid of grubs and restore my lawn?
The experts at Acenitec recommend treatment in late spring or early summer to combat grubs at the optimal time. “It’s a good idea to water both before and after treatment so the active insecticidal ingredient can get down into the soil where the grubs are active,” says Acenitec owner Gary Roberts. After grubs are effectively treated, re-seeding of the damaged patches will be necessary to re-grow healthy grass.
