The other thing to remember is that Nosema cannot be shipped just anywhere.
I used it several years ago and it worked beautifully. Got control for 5
years or more. But now, it cannot be shipped into Kentucky (in fact to most
of the southeast!) because of an endangered locust!!!!! My neighbor can
spray with a non-selective insecticide that will, of course target that
endangered locust along with all the others, but I cannot use nosema. Go
figure!
