- The thatch layer in your lawn should be less than 1/2 inch thick. If the thatch layer is thicker than 1/2 inch you will need to remove it. Thatch layers encourage pests and also stop insecticide applications from getting down into the soil where grubs are present.
- Apply a product that is labeled for active grubs. Curative grub products typically come in two formulations, liquids and granules.

Most curative grub products require the application to be watered in to move the product down into to the soil where grubs are active. Be sure to read and follow the product label for best results.

It does take about 2 years to see the initial results but the spore keeps working to control grubs for at least 10 years.
