It is shown the wesen can use their wesen extensions without humans seeing it. In many fights Hank is there but sees nothing. It is after the fight that Nick has to tell him what they where fighting. Wu saw the aswang because she wanted him to. Just like in "Cry Luison"  AVa could see her husband and his brothers because they wanted her to see them. It has also be stated in "The show must go on" that wesen can not do a full woge repeatedly without having physical effects.
