The treated zone approach to termite control involves two stages:
Stage1: colony elimination using termiticide dust, baiting or foaming.
Australian Standards 3660.2 - 2000 states that in cases where active termites are present and where possible, a method of colony eradication should be used prior to the installation of a chemical treated zone. Active termites are skilfully dusted with a termiticide dust such as Termidor or Intrigue by an Austrapest professional and qualified technician. This system exploits termites grooming and transfer of food behaviour and the dust particles are carried back to their nest with the aim of colony elimination. This is not a “stand alone” method and needs to be followed through after a few weeks with a follow inspection and with a continuous soil treatment. Baiting or foaming can also be used for colony elimination.
Stage 2: continuous chemical soil treatment zone:
Chemical treated zones have been used in termite management extensively since WW2. Products used have changed over the time. The Organochlorines have not been used since 1995.
While these products were very effective in the control of white ants (termites) and when used properly posed minimal risk, the concern was that they were persistent and bioaccumulated in the food chain and they were often misused.
Today with Environmental concerns and much research, we have a choice of lower toxicity products which will give long term control against termites. Austrapest uses the non repellant termiticides such as Imidaclopird (Premise - developed by Bayer) and Fipronil (Termidor by BASF).
Products are applied with the lowest doses and according to the labels. The soil treatment method is very cost effective and achieves long term protection for the building with a single application.
Termites will come into contact with products (such as Termidor or Premise) on the edge of a treated zone. Termites while foraging, will pick up the product and also transfer the termiticide to others in the nest. The treated zone protects the building.
Austrapest only uses products approved by the APVMA (Australian Pharmaceutical Veterinary Medicines Authority). We also like to use R & D (Research and Development) companies as they offer scientific advice or back up should it be needed.
Products used to the label requirements are relatively safe to the occupants, pets and the environment. Some of these products are used on pets for flea control.
While the chemical treated zone is a single application, it is important to follow up with an inspection 6 months later in accordance with the new Code of Practice for Prior to Purchase Timber Pest Inspections and Australian Standard 3660.2 - 2000, then at regular 6-12 month intervals as recommended by by Austrapest professional Pest Managers.
