- Roof vents and soffit corners. - Gaps where the roof meets the wall. - Uncapped chimneys. - Crawl-space doors and foundation vents. - Under decks, porches and sheds.
If an animal gets inside the house.
Open an outside door or window in that room, then leave. Keep kids and pets away. Is it a bat, and was someone asleep there? Call your health department first. Close interior doors so it stays in one room.
Droppings and cleanup.
- Don’t sweep or vacuum droppings dry. - Wear gloves, a mask and old clothes. - Wet droppings down, then bag them. - Large attic messes are a job for pros.

- Trash: locking lids, or keep bins in the garage. - Pets: feed them indoors. - Birds: use a seed tray, and sweep up spills. - Fruit: pick up what falls. - Cover: clear brush and wood piles near the house.

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?
Fencing that works.
- 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.
