Asian longhorned beetles (ALBs), which are harmful to many broadleaf trees, have been spotted in eight European countries to date. The city of Winterthur (Switzerland) is the first place in Europe to eradicate a large beetle infestation in just four years; elsewhere, this has so far only been achieved in over ten years. According to a specialist, the recipe for success requires systematic action against the beetles, well-coordinated control measures and active information of the public.
