This paper reports detailed laboratory evaluations of the termiticidal efficacy of permethrin and fenvalerate-treated wood blocks. Comparison between artificially wheathered permethrin-treated blocks and unweathered blocks is given. The effect of a 6-week soil burial period on pyrethroid-treated blocks at a retention of 0.08 kg/m³ is also reported. Toxic or protection threshold values for the two pyrethoids are summarised. The significance of these is discussed with reference to their acceptance by the Australian Department of Health (Plant Quarantine) for the treatment of timber components in shipping containers.
