Found this guy upstairs in our house. Wondering what it is? Want to release him back into the wild. Should I be worried there are more in my house?
How you want your letter signed: Krissi
We are pretty confident telling you this Beetle will not harm your home nor its occupants, though we are having a difficult time identifying it. Though it resembles a beneficial, predatory Ground Beetle, the antennae seem entirely too serrated to be a member of that family. The antennae remind us most of a Longhorn Beetle in the family Cerambycidae, but we don’t believe that is correct either. We suspect this is a Darkling Beetle in the family Tenebrionidae, but we have not been able to identify the genus nor species. We are going to contact Arthur Evans and Eric Eaton to seek assistance.
Hi again Krissi,
Does anyone in your home have a pet that requires worms from the pet store? See Arthur Evans identification below.

I would agree with Art.
