The first step is to Identify the presence of the woodworm. This is easily done by scanning the surface of the wood itself. Woodworm is distinguished by a series of tiny holes that are known as flight holes in the wood surface. The holes will look like a series of tiny pinpricks. Make sure to inspect the entire surface of the wood, since the condition may only affect 1 small section.
Determine the extent of the damage. In many cases, woodworm is found along the upper layer of the wood, while leaving the heart and the surrounding layers untouched. When this is the case, the wood item will still be relatively strong and capable of being salvaged. Should the wood tend to crumble or break off with ease when handled, this is a sign that even with a treatment, there is not much hope of saving the item.
Be sure to wear appropriate safety items. There are several liquid solutions on the market that are used as woodworm treatments. All of them contain chemical compounds that could produce fumes that cause illness or some type of adverse reaction when inhaled. Before working with the solution, take the time to put on a face mask along with a pair of safety goggles and gloves. This will minimize exposure to the skin and eyes as well as prevent inhaling the gases released during the treatment phase
Coat the surface of the damaged wood with either a brush or an insecticide type spray. Applying an even coat will help to kill any lingering infestation and prevent any further destruction to the surface of the wood. Allow the coat to dry before attempting to move the wood. This will allow the solution to permeate the wood surface and help expedite the woodworm eradication.
After finishing the woodworm treatment, allow up to a full day for the solution to settle into the wood and kill any lingering beetles that may be remain in the flight holes. During that time, keep children and pets away from the area, so they are not exposed to the fumes or come in contact with the wood during this period.
