Would the rain wash away or decrease the effectiveness of the product?
Milky Spore Powder does need to be watered into the soil with rainfall or irrigation after application, so rainfall actually helps the Milky Spore to reach the grubs in the soil. If you has so much rain and flooding that the soil was physically removed from the area and needed to be replaced, then we would recommend reapplying in those areas.
