The
common name for numerous species of social insects
that can damage wooden structures such as furniture
or houses. Of about 2000 known species, most are
distributed in tropical countries and some inhabit
the temperate regions. Termites are sometimes
referred to as 'white ants' because of their creamy
oloring and ant-like appearance. There are over 350
species of termites in Australia of which some 20
species can damage timber in houses. In nature, they
assist in the recycling of organic matter and
nutrients back to the soil.
There
only 6 families of cockroaches found worldwide,
consisting of 4000 species. Australia has
representatives of 5 of these families but with only
428 species present. Half of a the cockroaches in
Australia can be found in the Blattidae family which
includes both the native and introduced species. Go
to our links section to find out more about the
families of cockroaches.
Spiders are invertebrates with a two part body (phalo
thorax and abdomen), biting chelicerae and silk
glands that discharge through spinnerets. They have
4 pairs of legs and additional pair of short
appendages (pedipalps) beside the chelicerae. Eight
is not only the number of legs spiders have. The
original spiders and most still have eight eyes and
if that is not enough spiders still live today which
have the original complement of eight spinnerets.
Almost
too familiar to need description, mature female
redbacks are jet black spiders with a variable red
stripe on the back of their spherical abdomen. Their
tough, untidy webs are usually near the ground with
the spider hiding in a shelter in a corner, often
guarding her round woolly egg sacs. Immature females
are smaller, usually brown with whitish markings.
Males are rarely seen; they are small and brown with
red and white markings.
Ants
are social insects which live in nests. The nests
vary in size depending on their age and the species
of ant. They are generally found in the ground, in
wood or under rocks, although ants can also nest in
walls, fireplaces, under paths and in buildings. />
Ants are a very successful insect group with over
1200 species occurring in Australia. All species can
be beneficial to the environment. Some eat insect
pests such as termites, their nests improve the
soil, they quickly recycle nutrients back into the
soil and they are food for a wide range of native
birds, reptiles and other small animals.
Red
Imported Fire Ant, enopsis invicta, is a serious new
pest which has been detected in Queensland,
Australia. They inflict a painful sting and if not
eradicated will seriously affect our lifestyle. They
are the greatest ecological threat to Australia
since the introduction of the rabbit and are
potentially worse than the cane toad.
In
Australia, a number of rodent species are
agricultural pests. Two species, the house mouse
(Mus domesticus) and black rat (Rattus rattus),
were introduced around the time of European
settlement. House mice are found throughout
agricultural cropping areas, and around sheds and
houses. When conditions are favourable, their
numbers can increase to plague levels. Black rats
are found throughout temperate and tropical
Australia in human-modified environments.
There
are 16 different families of fleas worldwide,
consisting of about 2380 species. In Australia 9 of
these families are represented with just 90
different species. About half of the endemic species
that occur in Australia are found in the iopsyllidae
family. The Pulicidae family contains many of the
introduced fleas such as the cat, dog and human
flea, as well as some native species. Go to our
links section to find out more aboutout more about
the different families of fleas.
Bees
belong to the insect Order Hymenoptera, which
includes wasps, ants and sawflies. In Australia
there are four main bee families: Apidae, Colletidae,
Halictidae and Megachilidae. Many of these bees are
solitary nesters, while others may share a nest.
Others are fully social species. Although some bees
sting, they are not considered to be pests as they
play an important role in the Australian environment
as key pollinators of many native plant species.
Wasps
are a diverse group of insects. In Australia alone
there are over 12,000 species, ranging from the tiny
priid wasps, which are barely visible to the naked
eye, to the spider and cicada-killer wasps, capable
of taking large prey. Most wasps have carnivorous
larvae that feed on other insects and spiders. The
adults provide food for them by capturing prey or by
laying the egg on or near the food source, which
might be an egg, larva or pupa of another insect.
Lice
are small, wingless insects that are parasites of
birds and mammals. They are usually less than 10
millimetres in length and are rarely seen without
the aid of a microscope or magnifying glass. Lice
are short lived and usually host cific.A few species
of lice have adapted to live and feed on humans,
such as the head louse (Pediculus capitis), the eggs
of which are commonly called nits and the body louse
(Pediculus humanus).
There
are only 4 families of silverfish found worldwide,
consisting of about 370 species. In Australia just 2
of these families are represented with 28 species
present. The 2 Australian families are easily
separated from others found throughout the world as
the oletiidae family are eyeless and the
Lepismatidae have only small compound eyes. Go to
our links section to find out more about about the
families of silverfish.
This is one of the largest insect orders in the
world and includes many familiar insects such as
mosquitoes, midges, sand flies, house flies and
blowflies. Many species of Diptera are important due
to the role they play in disease transmission, which
includes such things as mosquitoes that spread
malaria in many underdeveloped countries
Carpet
beetles damage fabrics, furnishings and clothing
that contain wool, silk, hair, bristles, fur, or
feathers. Synthetic items are resistant to attack,
but mixtures of synthetic and natural fibres can be
damaged. The natural habitats of carpet beetles are
nests of birds, rodents, insects, and spiders. The
beetles are pollen feeders and can be found in large
numbers in flowers; they can be brought into the
house in cut flowers.
Although less common than carpet beetles,
clothes moths are commonly experienced in similar environments
to carpet beetles, namely woollen materials, felt, fur and
other materials of animal gin.The two most common species of
clothes moths are the case making clothes moth (Tinea
pellionella) and the common clothes moth (Tineola bisselliella).
Wood borer are insects which damage wood
by tunnelling at the larval (grub) stage for food or leaving
an emergence hole on the surface of the wood after becoming
an adult (beetle). These emergence holes ('pin holes') are
quite visible and are usually the first signs of an active
infestation of wood borer.
The
fruiting bodies of wood decay fungi vary in size,
shape and colour. The type of fungi encountered by
building inspectors & pest controllers usually
reside in poorly ventilated sub-floors, below wet
areas of the home, exterior timbers and in areas
that retain water in the soil. The durability and
type of timbers are factors along with the
temperature and environment. Destruction of affected
timbers varies with the symptoms involved.
