they do fly - we had a mini infestation a year ago. You should check your clothing. A sure tell tale sign - did you find larvae husks anywhere? The larvae live off clothing, rugs, etc. So if you are finding holes on your socks - it's the beetles and not moths. these guys are amazing

and even if it's not carpet beetles, they can help. They are also very fairly priced.
