Yes that looks like the bugger.
What kind of tree is that?

Maple.

There are two more maples and several other trees on the property :(

Last year that tree started looking a little sad, in spring it made a few leaves, then died.

Maples are definite breeder trees. So yeah, judging by what you described, that tree needs to be chopped down and the wood solarised or burned.
 
Just found this thread - I'm sure I've got one (or more) of these MF's in my patio roof rafter. How do I get rid of the beast?

Don't think they attack dead wood. That's termites. These buggers attack living trees.

The MF flies ands looks like a beetle - sounds like a beetle, so don't think its a termite. I haven't had a chance to catch a good look at it though. I guess I'll squirt some poison into the hole and seal it with something. See what happens.

They are around 1,5mm in length so that may help you ID...
 
There is even a large blue wasp that bored into wood. We have one boring into the eves at our front door.

Edit - turns out he is a carpenter bee

Paraffin! It's an extremely good insect repellent on wood.

But wont that make the wood potentially more prone to catching alight? I assume paraffin is absorbed into the wood?
 
I would just put a little rag with paraffin hear the hole it is boring. Would not paint it onto the wood.

From Total:

Our paraffinic oils are used as insecticides and acaricides to protect crops. They also have a fungicidal effect and may be used to fight diseases such as Sigatoka or powdery mildew.

Paraffin oil has a physical mode of action: the oil film covers and smothers the insect eggs and larvae. It also forms a barrier that can prevent the transmission of certain diseases or the arrival of spores. This explains our products' broad spectrum of action without any known development of resistance.

So you do need to paint it onto the wood.
