How to Get Rid of Lawn Grubs

While grubs may be present in small amounts on lawns, their presence can cause lawn grub problems. The larvae attract larger animals that consider them tasty. We offer expert advice to help you get rid of lawn bugs and prevent them from returning.

What are grubs?

The term "grub" can be used to describe the larvae of various species of beetles. Their eggs are dormant during the winter months and then hatch in spring when the ground heats up. Lawn grubs feed on the roots of plants and, once they're grown up, lay more eggs to perpetuate the cycle.



Lawn grubs can be small and pale in color, with a darker-colored head. After being exposed, they curl up into a "C," and usually measure one-half to one inch in length.

Signs you Have Lawn Grubs

Grub damage is often confused with other lawn issues. However, if you are aware of what to look for, you can save your time and regain control. The following signs can be seen:

Increased Activity

Birds, moles, and raccoons all love lawn grubs as a source of food. Grubs may be responsible for increased activity, especially during the morning or evening hours.

Spongy Texture

Because grubs love roots, it is possible that there is nothing to anchor the grass to the soil. The grubs below may be exposed by removing the spongey patches.

Discoloration

When the roots are damaged, the grass will start to turn yellow and eventually die. You'll see brown patches in your lawn.

High Concentrations

You can test for grubs by waiting until the rain has stopped. After that, you will need to dig up one square foot of the lawn where the grass is brown. A treatment plan will be beneficial if your lawn has more than five grubs.

Nematodes

Natural treatments that do not involve chemical use include nematodes. These microscopic worms are released into the soil and then make their way into grubs' bodies. Once they are inside the soil, they release infectious bacteria that eventually multiply and prove fatal. The lawn may need to be treated with nematodes in liquid form. It can take many years for the nematode plant to establish itself.

Pesticides

If you find five or greater grubs per square meter, follow the label instructions to apply the appropriate treatment. To move pesticides from the root zone to which grubs feed, thoroughly water the treatment (1/2 to 1 inch of irrigation). All pesticide containers should be disposed of according to the label instructions. Never pour leftover pesticide down drains for storm sewers.

It all depends on where you are located as to when and how often pesticides should be applied. Get the best advice about pesticides from professionals by contacting your local landscaping experts.
