You can wait up 36 to 48 hours before watering in the Milky Spore. Make sure you water the Milky Spore before raking or mowing your lawn. The whole idea is to soak the Milky Spore into the soil where it will become available to grubs feeding on the roots of grass. Simply use an oscillating hose sprayer for 15 to 20 minutes over the entire treated area. There may still be some white residue but this is chalk used as carrier for the spores.
