Timmie,
 
From what I have been told you spray it on WHERE he is biting.  My ferret
started nipping and I sprayed it on my arm and the next time he nipped me
(he licks first so I really didnt get nipped that time) he got a taste of
it and pretty much stopped.  I dont think spraying it in his mouth is
teaching him not to bite.
