not a spider this time. take a look at the photos below and see if you recognize the culprit. i have a few carpenter bee's around so i am pretty sure its not them in this case. new dug-fir post that stays dry year around in old redwood structure about 6 feet off the ground. intrusion is definitely with the soft grain between the harder rings in the post. not a lot of saw dust like i see with the carpenter bee's. anyone?
