Thanks for the information everybody! :) Good to know it isn't anything more terrible than just simply flies in her ears!
I'll keep putting tea tree ointment in there (not the spray) and I ordered some SWAT so I'll be using that as well. I never knew tha fly repellent ointments/roll on flyspray actually worked! How nice! Lacey will put up with spray but she gets really nervous about it near her head (I've never sprayed her in the face but she came to me super headshy so who knows what happened there) and I really having her fear/dislike a daily summer event with me. Anyway, yay!
