Apparently these wasps only lay eggs on trees that still have their bark on them, and this is a key to the relative importance of these wasps in structures.
Their presence in the wood of a structure always is the result of their being built in with wood that was already infested.

 Wood Wasps Horntails Management Guidelines--UC IPM
The common names "wood wasp" and "horntail" are used to describe several kinds of wood-boring insects (families Siricidae, Xiphydriidae, Anaxyelidae, and Orussidea).
Many species of wood-boring beetles, especially those in the family Buprestidae (flatheaded or metallic wood borers) or the family Cerambycidae (which includes long-horned beetles and roundheaded wood borers), feed on live trees that are old or weakened or fire- or insect-killed trees but do not attack harvested lumber.
A female wood wasp inserts her ovipositor nearly 3/4 inch into wood of a weakened or dying tree and lays one to seven eggs.

In the vegetarian sawflies, the abdomen is broadly attached to the thorax and the ovipositor is rigid; in the higher wasps, the abdomen is flexibly attached to the thorax and the ovipositor is movable.
Wasp nests may be as simple as a straight burrow in the ground, like those made by the females of many digger wasps.

After a period of chewing, the wasp adds the paste to the nest structure and spreads it out with her mandibles and legs.
The reason for this is because wasp colonies feed on large numbers of caterpillars, bugs, flies, spiders, etc. and the meat would spoil if the wasps were to store it.
Stinging is an excellent defense in wasp colonies against predators and other possible dangers which present a threat to the nests and their occupants.

These wasps are members of the very large family of parasitic wasps (actually, parasitoids is the better term) known as the Ichneumonidae in the Order Hymenoptera.
Megarhyssa wasps (there are several species in Michigan) are able to thread a 4-inch-long ovipositor into the wood of the dead tree, where they presumably are able to deposit an egg in the tunnel of the siricid wood wasp, Tremex columba.
The wood wasps (family Siricidae) are also members of the Hymenoptera, but chew into standing dead trees.

Wood borers are instrumental in beginning the breakdown processes that prepare nutrients for reuse by subsequent plants.
The large, white, segmented wood borer larvae are responsible for the munching sounds often reported by visitors to burned areas or by owners of salvaged logs and firewood.
Wood borers only attack highly-stressed trees or wood pieces with the bark still attached, so the presence and emergence of wood borers is not a major concern to healthy trees or other wood (such as furniture).

It is at this point when local infestations begin to show themselves; wood which unknowingly has horntail larva or pupa is commonly used for construction since it is hard to detect these young and developing stages.
Furthermore, since most infestations actually exist when the wood is used or installed, any part of the structure which was created at the same time as the wood showing evidence is wood that could have activity.
Once you have determined if it's original wood used to build the house or some which was used at a later stage in the houses history, you should be ready to make a decision about what and how to treat.

 Wood wasp - Wikipedia, the free encyclopedia
The term wood wasp is a colloquial name applied to various unrelated families of Symphyta, whose only shared feature is that the larvae are found in wood.
The name is thus applied to "wood wasps" (family Xiphydriidae), "parasitic wood wasps" (family Orussidae), "cedar wood wasps" (Family Anaxyelidae), or, at times, to "horntails" (family Siricidae).
The female in the latter two of these groups has a long ovipositor at the back of her body which gives her a dangerous look, but they cannot use them to sting.
