Merit, or the active ingredient in Merit, Imidacloprid, is the best product for grub control. It is important to start treatment prior to egg hatch. For optimum control irrigation or rainfall needs to occur within 24 hours of the application to move the product through the thatch layer and into the soil. You can contact your local cooperative extension office to see when egg hatch normally occurs in you region. Dominion 2L contains the same active ingredient as Merit and can be used as a money saving alternative.
