Walk the foundation with a flashlight. Gaps at ground level let animals under the house.What’s that noise?
- Quick scurrying at dawn and dusk: squirrels. - Heavy thumps at night: raccoons. - Rustling at dusk at the roof edge: bats. - A strong smell under the deck: skunks.

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.
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.
- Identify: figure out which animal it is. - Check: look for babies first. - 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.
Where animals get in.
- 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.
Close interior doors so it stays in one room. 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.
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.
Keeping your yard less inviting.
- 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.
Wildlife myths.
- Out in daylight means rabid: not always; mothers forage by day. - Moving them is kind: often illegal, and babies get left. - Mothballs drive them out: they don’t, and they’re a health hazard. - Lights and radios work: only briefly.
Birds in vents and chimneys.
Starlings and sparrows love dryer and bath vents. Most native birds are protected while nesting. Wait until the young have flown. Then fit a vent cover that still lets air out.
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.
The tech walks the roofline and the foundation. They look for tracks, droppings and torn vents. They set a one-way door or trap. Later, they come back and seal up. Cleanup comes last.
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.
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.
- 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.
