   H,

   You can rid infested wood or furniture of beetles in several

   ways. Rough lumber can be kilned so that all parts of the

   wood are heated to 150° for three hours. That should kill

   powderpost beetles at all stages of their development. Interestingly,

   high kiln temperatures may make the wood more attractive

   to powderpost infestation later on. Above 113°, parenchyma

   cells are killed quickly and their starch content is

   fixed. Kilning below 113° depletes the starch and lessens the

   food available to the insects. Even this wood, however, may

   retain enough starch to support an infestation.

   If you cut away badly riddled portions of once-infested sapwood,

   you can use the rest of the wood. Be sure to burn the

   sapwood cutoffs. A coat or two of a hard surface finish such as

   varnish or lacquer should prevent any remaining adult beetles

   from laying their eggs.

   I've found one of the easiest and most effective weapons

   against powderpost beetles is the pesticide lindane. Following

   the instructions furnished with the product, mix a 1% emulsion

   of lindane, and spray or paint it on infested wood or on

   lumber that you want to protect. The emulsion will crystallize

   in the wood and kill the beetles as they emerge to lay eggs. It

   will also kill newly hatched larvae as they tunnel into the

   wood. Lindane can be used on in-place structural timbers, log

   cabins, barns, wagons and other outdoor objects. On old furniture,

   it might be wise to apply the emulsion on an unseen

   part of the furniture to see if it stains or discolors the finish.

   After it has dried lindane is considered safe for use around

   children and pets, but I wouldn't put it on lumber that will

   eventually come into contact with food.

   Sincerely,
