What the heck is making these holes?

[check]

Maybe I should set a couple of rat traps. Don’t have a camera.

Whatever insect it is it's a doing a nice job. I have seen bees do this..

I'm at a total loss and just want to follow along to learn what it is. The smoothness of the holes makes it very odd, also that there are so many. I've dealt with squirrels and racoons doing this to get into the attic of a house, but they only make the one hole and then they are done. Wood peckers are also bad on wood here, but I've never heard of one going inside a building before.

Is there any sign of poop anywhere? Can you spread a thin layer of cooking flower on the floor and check back for tracks?

Please keep us posted on what you find out.

The flour sounds like a good idea. I'd like to know what it is too. What's under those boards? Can you pull one up and look?

Maybe:

Floor made with used boards. Previous holes were drilled out and plugged. Plugs are now falling out.

Clean the floor very well, till you can see the grain. Any remaining secure plugs may be visible then.

Some new giant beetle species that is coming out of the melting permafrost?

do you, or a close neighbor have chickens, or other fowl? because this could be rats. but if they are coming into your shed, there should be rat droppings inside.. what you could try, is get a pack of 4 insect fogger cans, and set them off inside the shed, let that sit for the recommended time, what ever this is will either be killed, or will flee, I'd look outside for anything fleeing that spray.. you could put down sheet metal over the floor, it's pretty cheap, and nothing will be getting in anymore, but if it's something that eats wood, you could have big structural problems.. you could also try getting a funnel, and pouring rat killer down each hole..

Are there holes in the roof directly above these?
