Winter from Los Angles, Ca writes
When treating for powder post beetles, it is important to know that you may still see some beetles emerge even after you've treated with Bora-Care. This could be because the product may not have reached the center of the wood yet, or because there were still some dormant beetles at the time of application. With Bora-Care, the powderpost beetles do have to consume the wood in order to die. If you are still seeing activity, this means they are consuming the wood and dying. Any wood treated with Bora-Care, however, will be protected from any new damage. There is no need to treat again.
