Finally I got around to spend some time building the new workbench. The lumber is sitting around since early this year. The moisture content is down to about 9%. I started planning the lumber and noticed a hole bunch of worm holes in one of the boards. Look at the pictures attached, they are all from the same piece of maple. The holes are about 1/16″ in size. Then I planned down another board and it doesn’t have any holes at all. These are just 2 small boards were I wanted to look at the figure of the wood. The pieces are about 10″ x 45″ and 10/4. All the other lumber is between 8 and 10 feet in length. I am afraid to find some more worms in there. What is a good way to kill these nasty guys? Any help is appreciated.

Fumigate or burn them. Do not leave those boards around for a minute in your shop. If they are powder post beetles they will eat everything made out of wood.
How do I find out if they are active or not? It doesn't seem that there is any fine dust coming out of the wood.
I would dig down in the holes and see if there is anything in there. If there is any dust that is an indication of activity.
get em kiln dried. I would find a local kiln operator and have them cooked at least 24 hours above 135F this will kill all bugs and larvae. If your attic gets above 135 and its not too much wood thats another avenue.
Powderpost beetles can ruin wood in short order. You can kill 'em with chemicals but I did it with heat. I'd spent a long time milling my own t&g flooring from soft maple and the little b#$%@rds were active. I stacked & stickered the pile and ran the output from my wood furnace through the pile which I covered with a tarp. 24 hours of heat seemed to do the job.
