Pine borers and blue mold

Greeting all,

I'm laying up rough sawn timbers for a timber frame screen porch build and just milled up white and red Pine logs into a dozen 6x8x14 beams for use as roof purlins.  I sticked and stacked them under my Cover-it tent to dry for a year and just noticed that I have pine borers in one of the beams.

Also, I'm getting quite a bit of blue mold on a few of the beams.

I'd like to nip this in the bud before the little monsters ruin my timbers.

I've sprayed diluted bleach on pine timbers I had air drying in the past, but that was long ago and I can't remember the mix ratio.

Any help or advice is much appreciated.

In warm weather green pine stains and in the stickered pile it will until the m.c. drops a bit. If the cross flow is interrupted it will turn black and grow white fuzz. A tent or basement is a bad place.  Those insects should go away leaving their holes.

I doused them with a 50-50 mix of high test outdoor use only bleach and it seems to have arrested the mold.

I flooded the pine borer holes (only in two sticks) and jammed a nail down them to "mechanically agitate" the larvae and haven't observed any more saw dust piles being generated.

I also purchased some Tim-bor, but haven't had a chance to apply it yet.

The August humidity has broke and Autumn whether is finally here.... so hopefully, I'll be in good shape.

I have no idea about a PPB's hole being jammed working or not but can tell you for certain that wood/carpenter bees come out somewhere else! It "sort of works" but always.
