Help identify this Beetle/Grub ???

 When sawing 6"x12"SYP cants for my log home I found these critters, any ideas how to kill or prevent them  ???

I know them just as pine beetles and I've got a whole herd of them chewing away at some pines I had to clear from the spot I'm building a house for my daughter on- planned on peeling these skinny logs for poles and furniture but got caught up in the actual building and let them set too long.  They don't eat much, usually, just make tunnels, lay eggs and turn into beetles to carry on the family line, so to speak.  I burn them when I catch them, though- better to not have the hungry offspring looking at the rest of my pines with that devouring eye...  >:(

I found some of those the other day in freshly sawn ( but not freshly felled ) balsam. Creepy.

Decided that I didn't really want to take them or the wood home to make little roof trusses 'cause I didn't know how long they would be crawling out and maybe dropping on my head. Eeeewwwww. I'll save that wood for another project.

We call them pine borers,if you can get rid of the pine bark on a log their not that big a problem.Had a bunch of pine chunks I was going to cut into shingles those DanG borers made such a racket knawing, I could hear them from my bedroom.If you must hold pine for a wile before cutting strip the bark as soon as it loosens.

They make good fish bait!  Just knock the bark off...I've seen them get pretty big.

Round-headed and Flat-head borers like that don't attack dried lumber and are not associated with reoccurring damage.  They will take advantage of a felled tree.  The eggs are laid on the bark and the larvae grow under the bark until they are large enough to begin pupating.  Then they burrow into the log, usually about 4 to 6 inches and pupate in the bottom of a "J" shaped tunnel that usually has a round opening.  When they turn into an adult beetle they come back out, removing the frass and making the opening more oval shaped, and look for another downed tree, not a 2x4 like a powderpost beetle would do.

While inside of the tunnel, the opening is plugged with Frass.  Frass is the excrement of the larvae and strips of fiber that almost look like toothpicks that the larvae uses to plug the hole.
