eclayne said:I laid down Milky Spore 2 yrs. ago on part of the lawn and garden where I plant Callas, which JB love. This year I've seen only a handful and less than a handful of blooms chewed up. I'd heard very mixed reviews but am glad I tried it. Has anyone here tried it?

Milky Spore is a bacteria, although my niece informed me they're not called bacteria anymore, which creates a disease specific to JB. By creating this milky spore which the beetle larvae eat, the infected larvae eventually die and burst, releasing more bacteria into the soil. As I remember it takes a few years to reach maximum effect. I think I also remember Lee Reich mentioning that it's effectiveness is mixed, depending on your soil and climate. Anyway the JAPANESE BEETLES, which were a real menace, are now simply a nuisance.

I didn't get it precisely right but here's a link to further explain:
