I read the whole topic (I’m interested in it a long time), a literature (not advertising) on this issue there is not enough. Pests can be divided into two groups:
1 - timber beetles.
2 - house beetles.
The first group grow in a fresh wood at the time of acquisition of certain wood moisture content, they can penetrate into logs and wood material. There were instances when they affected boards composed in pads for the dryer (not dried yet). After dropping the moisture of wood, these bugs do not penetrate into the wood and don’t live more than one life cycle in a tree, and they don’t hit the wood twice.
These beetles leave holes of 1-2 mm, they don’t make a threat to a tree, they don’t stay in a finished product. They affect more often a white spruce.
In one of the posts about a carcass have been described those bugs. There no problems with them.
These beetles don't practically affect a fir, but if you leave pine logs with a cortex, then the wood will become soft, and it will be nice for a bark beetle. It leaves large, up to 5 mm moves irregular-shaped. Just after the drying of wood, they leave it.
They damaged a shaped beam (in one of the posts in pics) when it was a log in a wood depot. Now it isn't in a wood, so it makes no sense to change logs. It’s enough to gloss holes with a white glue and a sawdust.
The second group is more difficult. There are many house bugs, that hit a tree not earlier than three years, depending on a region, most of them leave the tree after a usual treatment of poison from insects.
But some problems may arise, that is why there are rumors about abandoned villages, although as I think there were other reasons.
Therefore, with household beetles each case needs to be analyzed separately, with the assistance of specialized literature, and listen less to advertising, in most cases they only induce panic.
