Last year was a very bad year in our area for grubs, so I am expecting (and starting to see) many, many Chafers flying around now. These Chafers will eventually mate and lay eggs. When would you apply granular Merit (with fertilizer combo)? I'm planning to apply June 9th - June 20th. Since I'm starting to see Chafers now, is June 20th too late? I've heard up to July 4th is fine, but I'm concerned since I'm seeing Chafers now.
