I haven't found any on the girls yet, but I found one on my stomach last night

Ewwww, I felt like I had bugs crawling all over me after I found that tick! It was deeply imbedded too.

Now hubby tells me to watch for a bulls eye type ring on the spot where the tick was...just great!
Somebody posted this link the other day. It's for natural flea and tick remedies. I hope this helps.
