TICKS, Oh how I HATE these nasty little creatures.

I was getting ready to give the babies a bath and I was trimming ears and found two ticks on Trixie's head.

Both of them were right by each other and close to her ear. They probably got on her a couple days ago when we were at the park. I feel so bad now and she was crying when I was trying to get them out.
I don't know what to do. I checked all the babies but those things are so tiny and with all the hair its pratically impossible to see them. Does anyone know of anything that I can put on the babies to help keep these things off them? I feel so nasty right now and itchy. I HATES BUGS!!
Thanks for letting me vent and any help is appreciated!!
