How do I know if I have Active Grubs or Grub Damage?

As fall begins to approach, the cooler weather may provide your lawn relief from the stress of the summer heat and humidity, but it also brings another threat to your lawn’s health. The month of September and into early October can bring grubs to your yard. These grubs can cause serious damage to your lawn, ruining the hard work you put into maintaining it over the summer.

What are Grubs?

Grubs are the larvae of beetles, typically hatching between late August and early October. Common beetles in Southwestern PA include:

  • Japanese beetles
  • May/June beetles
  • Oriental beetles

Throughout the summer, beetles like the oriental beetles and other similar beetle insects will begin to attach themselves to your grass and other plants, eating them. After the beetles have had a hearty meal, they will mate and then lay eggs. Their eggs will gestate over the course of a month or two, and when they hatch, they become hungry grubs.grubs, grub control, grub dmaage

Grubs feed on the roots of your grass in the early fall months and then burrow into the ground when the season ends. When the warm spring weather comes back around, they come out of their dormant state to feed on your lawn again, turning into beetles.

Signs You Have Active Grubs or Grub Damage

During this time of year, there are a few ways you can determine whether you have active grubs or grub damage by simply looking at or feeling your lawn. Since grubs feed on the roots of your grass, they tend to damage the root to the point that it can no longer deliver water or nutrients to the grass. This can cause patches of grass to turn brown or yellow and begin wilting in those patches.

Your yard may also feel soft and spongy, and you may even be able to easily pull up sections of our lawn or roll it back like a carpet to expose grubs on the surface of the soil. Try pulling up the yellow or brown sections of grass, if it pulls up easily, be sure to check the soil surface for c-shaped, white insects that are roughly the size of a penny. If they are present, then you have active grubs.

Another sign of grub activity is the presence of raccoons, birds, or skunks digging up your lawn in search of grubs to eat.
