Insect pest ID?

[LCHIEN]

All of the descriptions that I have read describe EXACTLY what I witnessed, so I'm confident that I met my first carpenter bee.

From what I've read, I have some nest treatment to perform.

Quoting Wiki again:

Since previous nests are the primary nests each year, blocking or poisoning nests can often backfire on the homeowner, by encouraging the carpenter bee to bore new nests. Over time the burrowing of these new holes may weaken structures.

I also read that placing boric acid inthe hole will get the femal to drag it in to the larvae, killing both of them.

OTOH, maybe you can just turn on your cell phone:

On the serious side, they say the carpenter bees are seriously good pollinators:

Pollinator decline is a serious environmental issue and carpenter bees are being valued increasingly as important pollinators.

Cedar too

I have a cedar deck and cedar patio furniture and cedar planting bench (all western red).

About three years ago I notied a small, maybe 1/2 diameter perfect cricular hole with sawdut underneath on the planting table. Couldn't figure it out, watched it, but did nothing since saw/heard nothing for weeks.

Then maybe two years saw the same thing on a railing on my deck. Saw no saw dust, but its a well travelled area. Anyway, finally saw a bee/wasp like creature enter and exit. Bee spray seems to have ended that. Then last year one of the deck chairs got it, again bee spray and never saw again. We'll see about this year, but wonder if they've entered the home?

figured it was a carpenter bee, but didn't know much more than that. Thanks for the info.

And, I'm disappointed in cedar since it was supposed to a naturally defensible wood.
