Borers prefer wet wood, such as that found in the subflooring of a home. Ensure proper ventilation in timber areas to avert timber boring insects. Don’t block off the crawl space with clutter.
Since less sunlight hits the south side of a building, it’s also more susceptible to borer infestation. If the wood on this side of the house tends to retain moisture, you should be very vigilant about checking for wormholes.
Before bringing that antique or used couch home, be sure there are no worm holes in it.
Treating or painting wood before using it is the greatest way to keep borers away.
