Hello All,

I live in a condo and have recently seen these in the exit stair cases and now my unit. No idea what I'm dealing with and would love some tips and advice on what to do next. It feels like I'm starting to see more of these little guys pop up. The condo is brand new, in North America, and only 4 years old - so I have no idea how these little guys are popping up everywhere.

Any help on identifying this and advice on next steps would be greatly appreciated. Thanks!!!
