Hello! I live in Michigan and in my particular area we are having a HUGE problem with white grubs. There are whole yards wiped out in my sub from grub damage. Even worse, since it is a country sub, the skunks and sandhill cranes are killing yards digging up the grubs. Luckily, I have been relatively unharmed to this point. Anyway, my homeowner's association (I hate these associations, but that is another topic...) is encouraging everyone to get their yard treated with milky spore, to the tune of $250/acre. My lot is about 2 acres. While this sounds relatively affordable, from what I have read, a single tratment of milky spore will not cut it and multiple applications will be needed. Is this correct? I'd like to avoid the constant expense of buying Merit each season, but I also don't want to drop $500 on something that will not work. Any insights on how many applications would be needed to work for the Michigan climate?
