To protect wood from carpenter bees, first, apply a paint or varnish as these insects prefer bare, unpainted wood. If they're already present, use insecticidal dust in the holes to eliminate the larvae, then plug the holes to prevent further infestation. Regularly inspect for new activity, especially during spring, and consider applying residual insecticide to vulnerable areas as a preventative measure. For severe or recurring infestations, consulting a professional exterminator is recommended for more targeted solutions.
