If a skunk sprays.
- People and pets: wash with peroxide, baking soda and dish soap. - Tomato juice: it doesn’t really work. - Eyes: keep the mix out; rinse with cool water. - Clothes: wash with baking soda added to the load. - Under the house: air it out; the smell fades over days.
Babies found alone.
Call a wildlife rehabilitator. Baby animals alone are often just waiting for a parent. Leave them be and watch from a distance for a day. Hurt or clearly orphaned?

- Diggers: bury wire mesh a foot down, bent outward. - Climbers: an electric wire near the top stops raccoons. - Gardens: hardware cloth beats chicken wire. - Gates: keep gaps underneath to a couple of inches.
