.....so maybe I just didn't have many Japanese Beetles because of that 
or because they just aren't around me that thick.  I know they were 
there because there were some weeds they REALLY liked that were 
completely defoliated when I would come across, -- 

Japanese Beetles love to eat my grape vines and raspberry bushes.

Japanese Beetles emit a phermone that attract more JBs.  A classic case 
of positive feedback (in the engineering sense) results.  The first few 
plants that they set up camp on results in the numbers on that plant 
snowballing.  The mob spills over to nearby plants.  

I think that it is extremely critical to control infestations early in 
the season.  Otherwise you become a beacon to every beetle downwind of 
your vines.

Japanese Beetles do not respect property lines.  You would have to 
treat all the property in a plume for a considerable distance downwind 
of your grapes.   Difficult in the best of times.  Impossible if the 
wind changes direction.

JBs are slow and stupid in the cool of the morning.  A possible organic 
control is to open the door to the chicken house first thing in the 
morning, throw some scratch feed under the vines, and then vigorously 
agitate the vines.  The beetles will fall to the ground and remain 
immobile for a few seconds while they figure out what happened.

In my next life time I plan on tacking several of the phermone baited 
traps to a dock.  I will slit the bag.  Should have outstanding fishing 
next to that dock.

Problems are misplaced resources.
