Firewood insects: An indoor pest or not?

Jeffrey Hahn, Extension Entomologist

It can be common for wood boring insects to emerge from firewood that is brought indoors. These insects can also come from other wood such as decorations made of branches or from new construction. Fortunately, these insects are harmless to people and property and do not reinfest any wood in a home.

There is a wide variety of borers, including long-horned beetles, metallic wood boring (buprestid) beetles, bark beetles, horntails, and wood wasps, that are attracted to dying and recently dead trees. Parasitic insects, like ichneumonid wasps that attack these borers, can also be found emerging from wood.
