According to a 2012 report, figures show that termite infestations are costing Australians over $1.5 billion dollars a year in damage and repairs. Termite prevention is a simple but vital step that could easily save you thousands of dollars down the track. Our experienced technicians can apply termite zones that will ensure your property is safeguarded against termites.
A chemical termite zone is an effective solution for protecting your home or business against the damages caused by a termite infestation. The liquid is applied to the soil under or around the perimeter of a property to create a zone that either kills or repels termites. Due to the breakdown of the chemicals, the perimeter around the property will need to be retreated periodically to ensure your property remains protected.
It is very important that you DO NOT disturb any termite workings, leads, galleries, etc. before commencement of the treatment program. If you disturb the termites then these treatment procedures may be rendered ineffective.
Where applicable: Suspect trees and stumps within 50 meters of the structures (and within the boundaries of the property) will be tested using an auger drill to determine whether a termite colony is present in the vicinity. If a nest is located, it is destroyed by the careful application of a suitable termite control agent. After drilling, any living trees are treated with a plant protection compound to protect against any subsequent plant disease prior to the sealing of the hole.
Specifications for treatment of accessible subfloors:
A termite control agent is applied at the rate of up to 5 litres per square metre for horizontal zones and 100 litres per cubic metre for vertical zones so as to form a complete and continuous treated soil zone (both vertical and horizontal) beneath and around the structures. In buildings with suspended floors with greater than 400mm crawl space, perimeter zones should be installed to surround piers, stumps and service penetrations and completely abut all substructure walls.
Specifications for drilling of concrete slab areas:
Concrete slabs and paths, both internally and externally will be drilled using a concrete hammer drill. Holes around perimeter walls will be drilled in accordance with AS3660 at 150 – 300mm, depending upon the substrate beneath the concrete and the chemical used. Holes are drilled as close as possible, but no more than 300mm, out from the wall. The termite control agent is applied at a rate of up to 10 litres per lineal metre and up to 3 litres per hole. Holes will be sealed upon completion.
Specifications for ventilation:
The Australian Standard recommends that subfloor regions should have adequate cross flow ventilation equivalent to 7300mm2 per lineal metre on external and internal walls. This ensures that the soil stays dry and dampness and moisture is kept to a minimum as damp soil is a conducive condition for termite attack.
