Ants – on the bright side

Ants can be good – but when is the last
time you heard that? Sadly, ants are
much maligned and misunderstood.
The diversity of the total ant species in an
ecosystem can be an indicator of overall
environmental health. Having a diverse
community of ants and other insects helps
keep the entire ecosystem in balance,
which is important for all the plants, fungi,
and animals (including us) that share the
environment.
Ants are important components of an
ecosystem for several reasons. They
disperse seeds for propagation and their
tunnelling skills make them important in
nutrient cycling and soil aeration. They
prey on pest insects such as flies, termites
and cockroaches, but are also a food
source for many other animals.
There are more than 2000 ant species in
Australia, but less than a dozen of these
are commonly considered pests. The
majority of ant complaints received by
DPIRD concern mainly three species -
coastal brown ants, odorous garden ants
and white footed house ants.
Ants are social insects, existing in perfect
communal harmony. More than 95% of
ants exist underground with their queen,
and we never see them. Ants are in fact
so numerous, that if all the ants on the
planet were gathered up and weighed,
they’d outweigh all the humans put
together.
But what happens if your ants are one of
the exotic pest species and are outstaying
their welcome? Don’t feel too bad about
controlling them! They are usually not
friends of the native ant fauna, often
displacing them and then building up in
high numbers to the detriment of the entire
local environment.
Control when needed
As different ants require different control
methods, we suggest sending in ants for
identification. This also helps us screen
for exotic pests. We have a fantastic
webpage called ‘Ant identification, the key
to successful control’ (Google it!) or phone
our Pest and Disease Information Service
(PaDIS) for advice regarding sample
submission on (08) 9368 3080.
