viburnum under attack

Last year, a lovely viburnum shrub appeared in the very inhospitable gravel around a drainage pipe in our front yard.  I carefully dug it up, and made a new home for it in rich soil in the back.  It looked green and healthy last year, and leafed out well this year.
Then I noticed holes in the leaves, and soon there was nothing left but the veins.
Viburnum beetles have been a growing problem in the US and Canada in the last few years.  Adults bore rows of holes in the thin branches, and lay eggs that hatch in the spring.
The larvae eat the green leaves, leaving only the tough veins behind.  Then the larvae fall to the ground, pupate, and in the autumn, the new adults crawl back up the plant, bore holes, and lay more eggs.
In the mean time, the plant eventually puts out a few new leaves, but is considerably weakened, and does not have the energy to flower.                     
Online research recommends waiting until fall, cutting off and destroying the branches with the tiny holes, which will break the cycle.  That chore is on my to-do list in October.
