Powderpost Beetles in shop?

[whittle1]

I have just in the last few days seen what I think are powderpost beetles on a pool table in the corner of my shop, will attempt to attach picture. The lumber that goes in the shop is kiln dried and sterilized at 165 for a minimum of 24 hrs usually closer to 36hrs. I currently have 1000bdft of red oak that I was prepping for flooring but am now concerned it could be reinfested. The nearest source of green hardwood logs is about 50 yards from the shop. I have read the beetles are good flyers, could they travel that far? The Oak airdried for over a year and was below 20% when put in the kiln but even at that there was no visable sign of bugs. There are still no signs of bugs in the boards that have been planned on one side and sized to go to the molder. How would you recommend I go about tracking down the source. If the oak needs to go back in the kiln would it need to be stickered? The bunks I stack on are pine either 4 x 4s or landscape timbers.

Can you get a close up of the beetle?   Looks kinda big for PPB.

Are they active this time of year.  how long has the wood been in the shop and what is the temp in the shop.  any frass?  maybe it is just a small bug.  are there many?  I think dead stacked would be like a large cant of wood and require longer to sterilize to get to the center.  I think the air moving heat to 4/4 wood helps it all get done to the center.  the center of the theoretical cant (dead stacked boards) is actually a board that may not get sterilized.  I got a microscope online that plugs into my phone and take pretty good pics.

I have also used this for pics of end grain to ID wood.  Even got compliments from Danny (WDH) May God rest his soul.

Thanks I'll check it out. The Oak went from the kiln to the shop and was there for about 2 months before planning and sizing for molder. I'm not seeing any frass or sign of beetles in the oak. Will do an in depth inspection today to see if I can find any evidence anywhere in the shop. I have a couple hundred bdft of Birch bought from a supplier left over from a cabinet project that has been stored for about 6 months. I haven't dug into it yet. I have some pine cribbing that was outside for awhile that I stacked in the corner of the shop. If I understand correctly the PPB doesnt affect softwoods. The shop is around 60 deg. with electric heater no humidity control. The only place I'm seeing them is on the pool table felt. I've seen less than 12 over a couple days.  The little black %$$## stand out on it. They are alive and I have a video of one crawling but cant download it. Looking at pictures on the internet there is a lot of bugs that look similar. 
I knew but guess I was reaching on the question about dead stacking the boards to 
re-steralize. I guess trying to justify being lazy, knowing me I would have ended up stickering no matter the answer.

Ok emergency averted!!! I hope. So I did some more investigating and found a bunch of these bugs on a counter top near the pool table. I opened up a magnifer app and at 10x I could get a good look at them. The camera only goes to 5x but one of those pics popped up a link to look at Red flour beetle. I'm now thinking thats what they are. That makes sense because I have had snacks on this counter and it turned into kind of a catch all so they were hidden from view. I will attach pictures and would appreciate your reply's on what you think they are

By George, I think you have it!

Weevils in the flour.  They like grain bins too.

You may get fruit flies if you leave a few cans with a bit of beer in the bottom sitting around, or so I have been told and found after years of research.

Thanks everyone. It was a great relief for these to not be PPB. They all look so similar about like trying to identify mushrooms, except one of those will kill you and the other will make you wish you weee dead.

I don't believe any of us have ever left beer cans with any beer in the bottom.

for the record before I am banished by all the Hoppies in the forum.  The layer of beer left to waste in the can is prob. thinner than the layer of lacquer used to seal the can to prevent contact with the aluminum (pronunciation based on your country of origin).  the fruit flies always have a very disappointed look on their faces.  They even have a country song about "I shaved my legs for this?"

OK, y'all brought up beer and bugs, so:  A good friend of mine and I were working in his open shop and drinking beer.  We worked and drank some, at one point I picked up a bottle, saw it wasn't mine, set it down and picked mine, my partner saw me make the swap, figured it was his, picked it up and turns it down, retched, and sputters.  We have june bugs and they get in bottles, and he downed a couple.

It didn't help I couldn't stop laughing.

Always choose the lesser of two weevils!
