My 2nd-story deck has substantial damage from carpenter bees, mostly in the supporting joists. I'd love to tear the whole thing down and start over but with a daughter in college and another taking a trip to Italy this summer, the money just isn't there. I'm thinking of pumping insecticide into the tunnels and sealing them to kill the bees, then screwing fresh (treated and painted) 2x10s to the existing joists and overhead deck boards. That should restore the structural strength and then some, without breaking the bank. Any thoughts on the idea in general, or recommendations on materials?
