We moved into our new home last Janurary. It is 50 years old. At the time the house was pest free. This summer we started noticing tiny holes in the hardwood floors. It seems that we have Powder Post Beetles. The floors are sealed and treated. How could these bugs have nested? Can they nest again evern though the floors are treated?
I was thinking about spraying pesticide into the holes and then filling them. Will this work or will they bore out od new holes?
Thanks for any help.
