Opossums.
Opossums are quiet, slow and mostly harmless. They move into crawl spaces and under decks.
Skunks.
Skunks den under decks, sheds and porches. A strong smell after dark is the giveaway.

Groundhogs dig big burrows beside sheds, decks and foundations. Around Wentzville, they sleep through winter and wake hungry in early spring.

Getting them out the right way.
- Door: a one-way door lets the animal leave. - Seal: heavy metal mesh on every gap. - Recheck: make sure nothing is trying to get back in. - Identify: figure out which animal it is. - Check: look for babies first.
Where animals get in.
- Uncapped chimneys. - Crawl-space doors and foundation vents. - Under decks, porches and sheds. - Roof vents and soffit corners. - Gaps where the roof meets the wall.
If an animal gets inside the house.
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. Open an outside door or window in that room, then leave.
Droppings and cleanup.
- Wet droppings down, then bag them. - Large attic messes are a job for pros. - Don’t sweep or vacuum droppings dry. - Wear gloves, a mask and old clothes.
Keeping your yard less inviting.
- Birds: use a seed tray, and sweep up spills. - Fruit: pick up what falls. - Cover: clear brush and wood piles near the house. - Trash: locking lids, or keep bins in the garage. - Pets: feed them indoors.
Wildlife myths.
- Mothballs drive them out: they don’t, and they’re a health hazard. - Lights and radios work: only briefly. - Out in daylight means rabid: not always; mothers forage by day. - Moving them is kind: often illegal, and babies get left.
Birds in vents and chimneys.
Wait until the young have flown. Then fit a vent cover that still lets air out. Chimney swifts nest in chimneys in summer and leave in fall. Starlings and sparrows love dryer and bath vents. Most native birds are protected while nesting.
If an animal seems sick.
Staggering, circling or acting unafraid can mean illness. Keep people and pets inside. animal control or your local health department. Don't try to trap or touch it.
Pets and wildlife.
Keep pets' rabies shots up to date. Bring pets in at night. your vet if your pet tangles with a wild animal.
What a wildlife visit looks like.
They set a one-way door or trap. Later, they come back and seal up. Cleanup comes last. The tech walks the roofline and the foundation. They look for tracks, droppings and torn vents.
If a skunk sprays.
- 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. - People and pets: wash with peroxide, baking soda and dish soap. - Tomato juice: it doesn’t really work.
Babies found alone.
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? Call a wildlife rehabilitator.
Fencing that works.
- Gardens: hardware cloth beats chicken wire. - Gates: keep gaps underneath to a couple of inches. - Diggers: bury wire mesh a foot down, bent outward. - Climbers: an electric wire near the top stops raccoons.
