conflicting recommendations about japanese beetle grub control timing

Asked August 21, 2018, 4:28 PM EDT

U of MN Extension Service recommends application in late summer while Scotts (GrubEx) and our lawn service (TruGreen) recommends late spring (i.e., around Memorial Day). What should we do? Is doing it either time better than not doing it at all? (This is a repeat question that I just sent in but I think I forgot to insert my email address.)
