Ants
|
While it may seem
improbable, ants can be a serious pest in
nestboxes. However, ants are a natural
component of every tree's ecosystem and many
species will utilise a hollow as protection for
their eggs, particularly from rain. We
must assume that most of these can coexist with
other hollow-users without conflict.
|
The ants that do create
conflict are Polyrachis sp, and these
can monopolise hollows to the detriment of other
users. These are the ants that weave nests
in the leaves of trees using chewed vegetation.
They
are aggressive, give a nasty bite (although
not quickly) and emit an offensive odour when
disturbed.
|
They will also attempt to seal the
entrance to a nestbox using the same
material. The photo adjacent shows the
remnants of one such attempt.
They
seem to be most of a problem on broad-leafed
trees, or in trees with flaky bark such as
hoop pine.
The
best solution is to relocate the box to
another tree. We know of no other
long-term solution.
