Answers:    Do you own plant in you room that come from out side they could have be in them. Are you walls drizzling and deteriorate they could be coming in from that especially if your room is within the basement. check the closet allso the walls could be drizzling and you dont know it. That is gross i have problems beside those pesty ants.
