I was getting eaten alive every night when I went to bed.  My daughter suggested that it probably was my pillow.  The pillow I had wasn't washable so I looked for a new one.  I chose the Danish Pillow with Sleep Technology from Denmark.  As an extra precaution, I also got these pillow protector.  I have not had a bite since I started using the protector.  The only down side is that sometimes they get a little too warm.
