power post beetles in columns

I have four 11ft h by 2ft Ida x 6 ft circumference hollow wood columns that need treatment for power post beetles. It is cost prohibitive to sand down all the columns and treat with Boracare. Is this product an option? How would you suggest I apply and how much needed per column?


Termidor Foam is labeled to be used for powder post beetles and how much you need will depend really on how many holes you actually have to treat.  As this product does not penetrate into the wood you will need to treat each individual hole.  The foam generated has an expansion ratio of 30:1. In about 5 seconds 1 oz. of product becomes approximately 1 quart of foam.   Another option would be to still use the Boracare or Jecta and drill into the wood and inject it, as it will penetrate into the wood.
