Hello.  When my little one used to bite I got a spray bottle of water
and would lightly spray her and say "No Bite".  As she was learning and
suspiciously sniffing near ankles (her specialty) I would give a warning
spray near her and remind "no bite".  Eventually when guests were over
she would just need to be shown the water bottle to remind her to be on
best behavior.
 
Hope this helps
Risa
