Marvin from Matteson, Illinois writes
This is on a board of deck railing made from new wood that was installed, allowed to dry and then stained this past September. Wood shavings and debris were first noticed about a month ago. Recently have noticed dead adult beetles which lead to the discovery of the exit hole on the underside if the board.
Bora-Care is definitely the very best product to treat for powder post beetles. If the wood is stained, it will need to be sanded and stripped down to it’s original raw state. The idea is to ensure the Bora Care penetrates all the way through to the center of the wood so it lasts the life time of the wood. Powder post beetles can remain dormant inside wood for sometimes up to 30 years. So it’s very important to treat the wood with a product that will fully penetrate the wood and last the life time of the wood.
