I thought that the nematodes were difficult to apply properly because (IIRC)
they only act at certain stages of insect development and under particular
weather conditions. Also, the adult beetles may come from anywhere, not
just the yard that you own and can spray.

Since the beetle populations have seemed to vary with the harshness of our
winters, it's hard to tell if the nematodes have had any effect.

Where do you find these nematodes? Web site, catalog, garden center??
