Termite resistance of timber envelope treated with imidacloprid then modified by typical building site operations
K Day, A Siraa, P Lobb
Imidacloprid is a new envelope insecticide approved by Australian regulatory authorities for framing timber. It is a non repellent insecticide. Results are reported for timber envelope treated with imidacloprid and altered post treatment with typical building site operations to expose untreated surfaces. These modifications included, cutting, notching and drilling. Pinus radiata timber samples were tested against Coptotermes acinaciformis as described in AWPC protocols.
Results show that timber envelope treated with imidacloprid and modified post treatment with typical building site operations gave effective protection from Coptotermes acinaciformis attack. The results were comparable to timber treated with bifenthrin at equivalent rates.
