| Soil Barrier Chemicals - |
| There
are FOUR chemicals registered by the relevant Federal Government
- National Registration Authority for use in termite control
as a soil treatment chemical, namely; |
| |
chlorpyrifos |
| |
| |
bifenthrin |
|
| |
|
|
| |
imidacloprid |
|
| |
|
|
| |
fipronil |

| About
the Chemicals |
|
Termidor and
Premise are water based, odourless and of low hazard to
humans, dogs, cats and other mammals. Both are registered
as a low hazard Schedule 5 insecticide with a CAUTION
notation on the registered label. Fipronil - the active
ingredient in Termidor, has been used in the USA and Australia
since 1995 for flea and tick control on millions of cats
and dogs.
Termidor and
Premise do NOT have an obnoxious
odour or emit airborne residues or fumes. Termidor and
Premise represent modern technology... they are NOT organo-chlorine
or organo-phosphate pesticides.
Dursban and Biflex have a strong
repellency action to deter foraging termites. Whereas
Termidor and Premise are non-repellant to the termites.
Termites can enter the treated soil barrier without detecting
the Termidor or Premise chemical. The repellant nature
of Dursban and Biflex mean the termites can detect and
move along the soil barrier seeking a gap to gain entry
into the building.
Biflex Aqua, The new water based termicide
and insecticide from FMC is manufactured with the same
bifenthrin active as Biflex Aqua, except it's practically
odourless, which means it can be used indoors and outdoors.
It's this level of convenience, where one product virtually
does it all that's winning over time-poor pest controllers
in their droves.

| Intrigue |
Intrigue being
a dust is not an ideal product, as some termite activity
areas are moist causing the Intrigue dust to coagulate.
This is where the skill and judgment of the termite controller
is important to assess any high activity areas as being
sufficiently dry to be treated with Intrigue dust. Intrigue
should be used in conjunction with a complete chemical
soil barrier treatment using Termidor or Premise.
An insect growth regulator affects termites
by stopping the moulting process required for the termites
to grow. As the worker termites die off, the termite colony
declines to the point where it can no longer sustain itself,
ultimately leading to it's collapse and elimination. |

|
|
| Premise |
| Premise
has been used as soil treatment barrier against termites
for more than six years in Australia (more than eight
years in the USA) with excellent results for long term
termite control. We are not aware of any significant problems
during this period.
Premise will act to kill termites, in
the higher concentration treated soil areas abutting the
building. With Premise, termites that forage in the lower
concentrated treated soil areas, will become disorientated,
stop feeding, and are fatally diseased by natural fungi
and micro-organisms in the soil. |
| How
safe are these products ? |
Intrigue termite
dust is classified as a schedule 5 insecticide with a
CAUTION notation on the registered label - indicating
it is of low hazard to people, dogs, cats and other mammals.
Exterra and Sentricon termite baits are not scheduled
as hazardous products.
All the above termite baiting systems
are subject to regular inspection and monitoring by the
termite controller. The larger the number of termites
that consume the bait, the quicker and more certain is
the termite colony elimination process. It is usual to
reinspect the bait stations and the buildings and surrounds
every month to reposition, reapply or replenish the bait,
if necessary. This process is labour intensive so that
the long term cost of the monitoring / baiting system
may accumulate out of hand before the chance of success
or otherwise, is realised.
Intrigue termite dust can be applied
directly to live termites in their mud tube galleries
or infested timbers, whereas the Sentricon baits are placed
in their in-ground bait stations after removal of the
termite infested timber therein... which involves major
disruption of the termites and thereby cause them to avoid
the in-ground Sentricon bait station, entirely.
Sentricon was developed for use against
American termites, a different species that are not as
disturbance-wary as some of the destructive Australian
termite species. This serious short-coming is overcome
by the patented Exterra Termite Stations where the timber
is aligned around the cylinder such that the bait can
be inserted without such disturbance of the termites present. |

| Termidor |
Termidor is registered for
application as a chemical soil barrier to buildings, fences,
stumps and posts. Termidor will kill termites foraging in
the high concentration treated soil area next to the building.
However what's unique about Termidor is it's effect on the
termite colony. Termites foraging in the lower concentration
treated soil area pick up the chemical on their external
skin and it's delayed lethal effect is transferred back
to the central colony nest, where it is unknowingly spread
to the other termites by the regular feeding and grooming
of each other.
The Termidor fipronil product works quite
differently from other termiticide active ingredients. Most
other termiticides are repellents, which means they keep
termites away from a treated area, rather than killing them.
This means a gap in the barrier is more easily detected
by the termites, a major short-coming of the old-fashioned
termite control alternatives.
Termites tunneling in the Termidor treated
soil area abutting the building (of high concentration -
near the point of application) are killed outright.
Termites tunneling in the outer parts of
a Termidor treated soil area (of low concentration) will
not detect the Termidor which adheres to their bodies and
has a delayed lethal effect of several days - enough time
to be transferred back to the central colony nest. |
| Why Termidor? |
It appears that Termidor
in cases of a severe infestation, usually takes several
weeks to stop the termites in their tracks. In our opinion,
based upon a range of attributes, Termidor is the top of
the range "stand-alone" product in most circumstances
to protect a building under attack from subterranean termites.
Termidor has been used in almost 750,000
homes in the USA and field tested extensively in Australia.
Termidor was approved in November 2002 for use against Australian
destructive termite species. |
| How Termidor
affects termites |
The Termidor fipronil chemical
adheres to the termite exoskeleton and is readily adsorbed
through the exoskeleton and into the termite's body to immobilise
and kill the affected termite within a few days.
The termites spread the fipronil to other
termites during regular physical contact, particularly when
working together in close proximity, grooming and feeding
the rest of the colony, a regular function of their daily
life.
The termites cannot detect the fipronil
as it has no odour, taste or smell to the termites. Termites
carry away or cannibalise other dead termites, further spreading
the deadly effect of the fipronil chemical throughout the
colony. |

| Exterra
& Sentricon |
The Exterra termite monitoring
and baiting system was introduced in July 2002 by Ensystex
USA into the Australian market. The Exterra termite bait,
chlorfluazuron, is also an insect growth regulator.
Both Sentricon and Exterra systems have
their own plastic bait stations which must be used with
their product. These bait stations can be placed in the
ground and checked regularly.
Both the Sentricon and Exterra termite
baits are designed to be slow acting, non-repellant and
therefore spread to other termites in the colony before
the colony can detect where the deadly effect is coming
from. Termites have acute survival instincts. The location
of a toxic food source if detected, will be abandoned. Too
much disturbance of the foraging termites (workers and soldiers)
in a particular location, will alert the termite colony
to abandon the area. The termites appear to be gone, but
may in fact be entering the building in other areas. Your
home is a much bigger bait station. |
