Repelling carpenter bees

Asked March 21, 2016, 2:12 PM EDT

We have some areas of stained wood fascia that have old carpenter bee nests in them. When is the best time this Spring to have these areas treated? How long after treating should we wait before caulking holes? Will painting help? And should it be glossy? Thanks so much! Susan Fillion

The larvae of the carpenter bees are resting in these holes. A good plan would be to dip the end of a chalking gun into Sevin dust .and then fill the hole in one operation.Carpenter bees will stay away from painted surfaces.
