The true powderpost beetles cause the greatest damage because they can infest and reinfest wood after it is dry, reducing it to a dry powder. Losses from termites and decay are much higher. Current research on integrated protection against beetle infestations by scientists at the Southern Station has yielded effective dip-diffusion procedures using boron compounds to protect moldings made from a Brazilian hardwood (banak) against damage by beetles. In limited commercial use for over 4 years, the borate treatment has generated no complaints about insect, stain fungi, or decay damage to the. manuf acturer.
