I don't believe we have Japanese Beetle in Arizona so thinking it is not necessary.
It would be unlikely for you to find Japanese Beetles and therefore need a treatment like Milky Spore Powder. in Arizona since the climate is so dry and hot. We have an Inspection Guide for white grubs which shows how to check your lawn for this pest. Milky Spore will not harm the grass, so if see that Japanese Beetles have been found in your area, then you can use Milky Spore as a preventative treatment so that you do not get an infestation.
