But which species is our worst offender?

Tiny elm beetles eating the leaves and slowly killing some of our most historic trees have forced Orange City Council to spend $1000 a litre on insecticide to fight them.

The problem in Newman Park was highlighted this week.

But as the bugs bit, the bats were also preparing to bite.

Colonies making their annual migration west have stripped trees on Ploughmans Lane, taken roost in Cook Park and taken over Bathurst’s main park.

Now they have their radar set on bigger prizes – the next apple crop. Beware.
