Mole Scram Professional should be watered in immediately to activate the oils in the granules to begin the repelling process. We would not recommend waiting more than at least a couple of hours, especially if windy conditions are expected.
Please view the product label for more information.
The label does not indicate a specific time that you have to wait after fertilization when using the Mole Scram Professional. Depending on the type of fertilizer used, we suggest waiting 24-72 hours after fertilizing, which will give the fertilizer time to settle.
