Raccoons.
Never handle one. They tear open vents and roof edges. Heavy thumps at night usually mean a raccoon.
Tree squirrels.
Squirrels are busy at dawn and dusk. They chew small gaps into bigger holes, and wires too.
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.
Groundhogs dig big burrows beside sheds, decks and foundations. Around Naperville, they sleep through winter and wake hungry in early spring.
Bats.
Bats slip through gaps as small as a thumb. Look for droppings under a gap at the roofline.
Getting them out the right way.
- Recheck: make sure nothing is trying to get back in. - Seal: heavy metal mesh on every gap. - Door: a one-way door lets the animal leave. - Check: look for babies first. - Identify: figure out which animal it is.
Where animals get in.
- Under decks, porches and sheds. - Crawl-space doors and foundation vents. - Uncapped chimneys. - Gaps where the roof meets the wall. - Roof vents and soffit corners.
If an animal gets inside the house.
Call your health department first. Is it a bat, and was someone asleep there? Keep kids and pets away. Open an outside door or window in that room, then leave. Close interior doors so it stays in one room.
Droppings and cleanup.
- Large attic messes are a job for pros. - Wet droppings down, then bag them. - Wear gloves, a mask and old clothes. - Don’t sweep or vacuum droppings dry.
Keeping your yard less inviting.
- Cover: clear brush and wood piles near the house. - Fruit: pick up what falls. - Birds: use a seed tray, and sweep up spills. - Pets: feed them indoors. - Trash: locking lids, or keep bins in the garage.
Wildlife myths.
- Lights and radios work: only briefly. - Mothballs drive them out: they don’t, and they’re a health hazard. - Moving them is kind: often illegal, and babies get left. - Out in daylight means rabid: not always; mothers forage by day.
Birds in vents and chimneys.
Chimney swifts nest in chimneys in summer and leave in fall. Then fit a vent cover that still lets air out. Wait until the young have flown. Most native birds are protected while nesting. Starlings and sparrows love dryer and bath vents.
If an animal seems sick.
Don't try to trap or touch it. animal control or your local health department. Keep people and pets inside. Staggering, circling or acting unafraid can mean illness.
Pets and wildlife.
your vet if your pet tangles with a wild animal. Bring pets in at night. Keep pets' rabies shots up to date.
What a wildlife visit looks like.

If a skunk sprays.
- Under the house: air it out; the smell fades over days. - Clothes: wash with baking soda added to the load. - Eyes: keep the mix out; rinse with cool water. - Tomato juice: it doesn’t really work. - People and pets: wash with peroxide, baking soda and dish soap.
Babies found alone.
Call a wildlife rehabilitator. Hurt or clearly orphaned? Leave them be and watch from a distance for a day. Baby animals alone are often just waiting for a parent.
Fencing that works.
- Gates: keep gaps underneath to a couple of inches. - Gardens: hardware cloth beats chicken wire. - Climbers: an electric wire near the top stops raccoons. - Diggers: bury wire mesh a foot down, bent outward.
