natural remedies

So I noticed a few lice on my doe today. In this day and age we tend to over medicate everything so I would like to deal with this as naturally as possible. Would a small amount of garlic in her nightly feed help? (Can she have that)? Also, I know for humans and other species, a natural mint oil...

Does anyone have a good natural fix for fleas on young goats? Maggie and June are about three months old now and covered with fleas. I have a can of Y•Tex Python Dust, but after reading the back I grew a little concerned about dusting actual poison all over my babies! They are pretty miserable...
