Treatment options and typical costs
Inspection and Species Identification

- Best for
- Every job; the species decides the method
One-Way Doors and Eviction
$200–$600

Humane Live Trapping and Removal
$150–$500 per animal, plus trip fees

Local wildlife conditions in Baltimore.
An inspection in Baltimore usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Baltimore's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Baltimore and Maryland every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Baltimore sits in a humid subtropical climate, and that sets the pace for wildlife activity here: spring denning and fall (animals seek winter shelter). For Baltimore homes, the area is mostly urban, so wildlife pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by.
Brush, mulch and fallen fruit near the house give animals cover and food. Keep the edges tidy.What’s that noise?
- A strong smell under the deck: skunks. - Rustling at dusk at the roof edge: bats. - Heavy thumps at night: raccoons. - Quick scurrying at dawn and dusk: squirrels. - A big burrow beside the shed: groundhogs.
Baby season.
Never seal a hole while babies are still inside. Bat exclusion waits until pups can fly, usually by mid-August. Around Baltimore, most babies are born from about March through June. Mothers look for warm, dry spots like attics and chimneys.
A year of wildlife in Baltimore.
- Fall: animals hunt for winter dens. Seal gaps now. - Summer: highs near 88°F in Baltimore. Animals roam at night. - Spring: babies are born from about March through June. Don't seal while young are inside. - Winter: lows near 27°F in Baltimore. Animals den up in attics.
Raccoons.
They tear open vents and roof edges. Heavy thumps at night usually mean a raccoon. Never handle one.
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 Baltimore, 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.
- 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. - Recheck: make sure nothing is trying to get back in.
Where animals get in.
- Crawl-space doors and foundation vents. - Uncapped chimneys. - Gaps where the roof meets the wall. - Roof vents and soffit corners. - Under decks, porches and sheds.
If an animal gets inside the house.
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. Call your health department first. Is it a bat, and was someone asleep there?
Droppings and cleanup.
- Wet droppings down, then bag them. - Wear gloves, a mask and old clothes. - Don’t sweep or vacuum droppings dry. - Large attic messes are a job for pros.
Keeping your yard less inviting.
- 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. - Cover: clear brush and wood piles near the house.
Wildlife myths.
- 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. - Lights and radios work: only briefly.
Birds in vents and chimneys.
Wait until the young have flown. Most native birds are protected while nesting. Starlings and sparrows love dryer and bath vents. Chimney swifts nest in chimneys in summer and leave in fall. Then fit a vent cover that still lets air out.
If an animal seems sick.
Keep people and pets inside. Staggering, circling or acting unafraid can mean illness. Don't try to trap or touch it. animal control or your local health department.
Pets and wildlife.
Bring pets in at night. Keep pets' rabies shots up to date. your vet if your pet tangles with a wild animal.
What a wildlife visit looks like.
They set a one-way door or trap. They look for tracks, droppings and torn vents. The tech walks the roofline and the foundation. Cleanup comes last. Later, they come back and seal up.
If a skunk sprays.
- 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. - Under the house: air it out; the smell fades over days.
Babies found alone.
Leave them be and watch from a distance for a day. Baby animals alone are often just waiting for a parent. Call a wildlife rehabilitator. Hurt or clearly orphaned?
Fencing that works.
- Gardens: hardware cloth beats chicken wire. - Climbers: an electric wire near the top stops raccoons. - Diggers: bury wire mesh a foot down, bent outward. - Gates: keep gaps underneath to a couple of inches.
