Hi Nicole Although the antennae certainly look like those of *Stegobium*, other species in this family also have this configuration. I am having difficulty seeing any longitudinal striae (grooves) on the wing cases, which suggests they could be *Ernobius*, a beetle whose larva feeds under bark on trees - a very different lifestyle from *Stegobium*. It would be prudent to get a positive identification before deciding on a course of action. Best wishes Tony
