Identification: It’s common for white grubs to infest grass, causing damage to your lawn. Adult grubs are typically C-shaped, white or gray in appearance, and have brown heads with six distinguishable legs. The damage they leave on your lawn appears similar to drought stress, but the grass will come up easily when pulled. This is because the grubs have eaten the root system. A heavy infestation consists of at least 10-12 grubs per square foot.
Life Cycle: Grubs begin the year deep in your soil, then make their way toward the surface eating roots and reaching pupae level in the summer. At this stage, they also lay eggs before heading back into the soil in the fall. See the life cycle picture for a better description.
