We call them lawn ghosts because you never see them. Their common name is grubs. Grubs are prevalent in Lubbock lawns. They are essentially invisible to us because they hatch, grow, and feed underground. Grubs hatch from beetle eggs including June bugs. The larvae feed on the roots of your grass in July and August. You don’t usually see the damage until late August or early September.
Timing for Treatment of Grubs Is Critical
The best time to treat for grubs is at the end of July and the beginning of August because that is when grubs are most easily killed. That is when the grubs emerge from their eggs and burrow up into the top layer of soil where they eat the roots of the grass. At this stage, the grubs are young and more fragile, but most importantly, accessible. In early fall, they burrow down four to eight inches into the soil away from the cold (and down where any treatments can’t reach them). When they return in the spring, they will be older and hardier. Get your grub treatment down by the end of July or early August to make sure it is the most effective.
Signs to Look for on Your Lawn
With a bit of general knowledge, you will have a better chance to diagnose lawn damaging pests. Then, you’ll know right away when it’s time to call in the professionals.
A few things that might point to an invasion of grubs in your lawn include:
- Your lawn feels spongy. This can occur before the actual browning of your lawn and can indicate grubs as well. It can actually be one of the first signs.
- You see signs that animals such as raccoons and moles are tearing up your yard. They enjoy eating grubs, but they also like eating red worms too, so if your lawn is looking rough, make sure you’ve checked for other signs of grubs.
- Brown patches in your lawn that never turn green. This could be the result of grub feedings from the previous fall. Try pulling up on a piece of the dead patch, and if it rolls up like a roll of carpet, you most likely have a serious grub problem in that area. If you find dead patches that come up easily, your grub infestation is nothing to joke about. To save your lawn, we recommend calling a lawn care company with an insect management program IMMEDIATELY.
