Loaded with firewood – and bugs

With Fall here now (we had -3°C a couple of mornings ago), I’ve loaded up the firewood room in the basement and the wood furnace is fired up.

But with the firewood in the house we also have new residents that we haven’t seen since May – wood bugs of some sort. There are only a few of them but I’d really like there to be none. If any of you know what they are exactly and how to deal with them, information will be gratefully received! They’re tiny, only about 1/8 of an inch long. The first photo shows one on a piece of lined writing paper – this is what my new Fuji does on the Super Macro setting.

Edit: From Comments made on this post, I learned that they were Spruce Bark Beetles.
