Hello, i live in New Hampshire. I keep collecting these fellas off my white walls. I havnt seen them in the past, but over this month of January I have been picking these off my walls. I live in a newly built apartment complex on the 2nd floor. I see one about every two -three days.

Could you please help me identify this creature and tell me why are they invading my room. I am slightly scared of bugs and such. Is this seasonal? What can I do?

Thank you.
