Pests boring into log

Hello. I hope you are well and in good spirits.

I've got a log of Arizona ash (Fraxinus velutina) split in half. I've seen a pretty rapid invasion of some kind of wood-boring pest since the night temperatures have risen above freezing.

What might be doing this damage? How might I stop the little critters? I've only seen tiny ant-like things running real fast on the surface. And once I saw a very small black beetle-shaped bug too.

It's hard to say from the picture but it looks like some sort of beetle. If the log has been sitting around after cutting or dead on the stump for some time, that is pretty common for beetles to lay their eggs on the dead tree and their larvae will tunnel in to feed, then turn into an adult and leave to look for other dead wood to attack.
