Killing Japanese Beetles

I know hate is a strong word used too easily in phrases such as I hate beets.  On the other hand, it is not hard to use the word hate when I am talking about Japanese beetles who destroy plants as you can see in my extra of the rose bush where I got most of the ones in the bucket above.  They develop from white grub worms that live in the ground and in season like right now they are especially destructive to roses, crepe myrtles, and the roots of grasses before they fully emerge to fly into various flowers and bushes.  I have taken about 4  buckets of them from the bushes in the last two days.  Good riddance.
