There are 2 different types of termite barriers; a chemical soil treatment and a baiting and monitoring system. Both are installed around your home and both target the elimination of termites and protect your home against future termite attack.
Chemical Soil Treatment
So the chemical soil treatment is effective it must be installed a maximum of 150 mm from the external wall of your home and go all the way around the perimeter of the dwelling.
If you have alot of concrete, then drill holes must be made 200mm apart for the chemical to be injected.
Where there are garden beds, grass or pavers, a trench will need to be made for the chemical to be added. So a complete termite barrier can be created; air conditioning units, water tanks, timber decks, hot water systems (basically any obstructions) will need to be removed and replaced so the barrier is within 150mm of the complete external wall of your home.
There are a lot of chemicals used with this system however there is only one that you should ask for, Termidor. Termidor has something other chemicals don’t have and that is the ‘transfer effect’. This means the termites don’t die instantly, rather they take the chemical Termidor back down to the nest which then achieves full colony elimination.
Baiting and Monitoring System
The baiting and monitoring system does not need to be as close to the external wall of your home, however unlike the chemical soil treatment it is made up of individual ‘stations’. In order for this system to be effective these ‘stations’ must be positioned a maximum of 3 meters apart, this is the optimal distance to eliminate the chance of termites entering your home.
The baiting and monitoring system can go around anything and everything, decks, pools, air-conditioning units, concrete etc so there is not need for trenches or removing or replacing any obstructions.
Each bait station is installed into concrete or the ground along with an attractant and timber. The combination of the attractant, the timber and the warmth and dampness of the soil acts as an attractant for termites that are heading toward your home. The stations are checked regularly by a qualified technician who then adds to the station a growth inhibiting bait which, similar to the Termidor has a transfer effect so full colony elimination can be .
Neither system is a one size fits all and there are multiple different reasons why a termite barrier can fail. For example;
- Being recommended the wrong system for the design or your home
- Poor installation
- Natural movement of the soil around your home
- The system installed is not managed correctly
- Inferior chemicals or bait is used
- And, conducive areas listed in your pest inspection report you which you can find under point 6 Conditions Conducive to Timber Pest Infestation and 7 Conditions Conducive to Undetected Termite Entry
When your choosing a system that is going to work for you, ask your pest inspector which one will work best for your home as well as the details on how the system will be installed and will installation be in accordance with the Australian Standard.
