News and Information

Termite management of these traditional forms of construction (unless built in underneath) is usually by means of ground separation and the use of physical barriers such as ant caps and metal termite shields. These barriers and shields should be inspected to ensure they are not damaged or covered by silt or mud etc and that the building and any attachments do not provide concealed access for termites to get into the house.

A licensed pest controller should carry out an inspection and assessment of the termite management system used and reinstate this in accordance with the requirements of the BCA, relevant Australian Standard (AS 3660.1) and manufacturer’s recommendations. Systems that are likely to have been compromised due to water, silt and mud build up etc include all chemical barriers and physical barriers such as stainless steel mesh (‘Termimesh’) and graded stone (‘Graniteguard’).

Termite treated framing

Some homes and buildings may have been constructed using H2 termite treated framing (‘T2’, ‘True Blue’ and other similar trade names may apply to these timber products) as a primary means of termite protection. Some of these treatments rely upon an envelope of the termiticide preservative that is applied to the timber at the time of manufacture. As water inundation is likely to have compromised this envelope, a licensed pest controller should carry out reinstatement of termite protection using an alternative physical or chemical termite barrier system as noted above.
