Hmmm, maybe it has something to do with her name??? (ie: GingerSnap)! (Sorry, couldn't resist!)
I've even tried spraying them with Apple Bitter and leaving them. That actually worked pretty good, but it's difficult to get them sprayed in time. Plus, it's just easier to pick them up if you're going to go to the trouble to spray them!
I know it's Yucky, but try not to worry too much about it.
