Your Japanese beetles are only around for TWO WEEKS??? They must have
come here (TN). It's my understanding that they are now mating; the
grubs will begin feeding in the yard later in August (time for milky
spore), and next year they'll be back. I read that four o'clocks are
tasty and lethal to JB, so I am ordering some seeds. I have been
gardening since 1969, but this only the 2nd year I have had a JB
problem.
