Id rather not use any pesticides to protect my viburnums from viburnum leaf beetle. Are there any non-chemical control options?
Again, note the most effective means of control for viburnum leaf beetle is pruning and destroying (by burning or composting) infested twigs after egg laying has ceased in the fall — anytime from October to April.
