How do lawn grubs affect lawns?

During spring and early summer, lawn grubs live in the thatch layer of the soil. This is the layer of dead grass and debris that lays just on top of the soil. This spongy layer protects the grubs and provides adequate food and water. White grubs actually eat the roots of the grass killing it over time, while cutworms eat the blades killing the tops first and then not allowing nutrients from the sun and air to reach the roots. Over time the lawn dies and you will find yourself having to put in a whole new yard.

Keep up a healthy lawn. If you have very little or no thatch for the white grubs to live in, they will pass by your yard and move to your neighbors (although ideally you want them neighborhoods away not just neighbors away). Although you may have plenty of desirable food in good healthy green grass, grubs can survive in an environment that is perfectly warm and moist. This will not happen without thatch.
