Treatment options and typical costs
Inspection and Species Identification
$100–$300

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

Exclusion Repairs (Chimney Caps, Vent Screens, Foundation Mesh)
$300–$2,500+ depending on scope

- Time
- Half a day to two days
- Best for
- Sealing the home after animals are out
Attic Cleanup, Sanitation, and Follow-Up
$500–$3,000+ depending on insulation removed
Providers in Somerville who do cleanup should wear respirators and bag waste on site. Homeowners in Somerville handling raccoon droppings without protection risk exposure to Baylisascaris roundworm eggs, which survive for years in soil.

Local wildlife conditions in Somerville.
Knowing Somerville'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 Somerville and Massachusetts 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. Somerville sits in a humid continental climate, and that sets the pace for wildlife activity here: spring denning and fall (animals seek winter shelter). In Somerville, 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. An inspection in Somerville usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first.
Walk the foundation with a flashlight. Gaps at ground level let animals under the house.What’s that noise?
- Heavy thumps at night: raccoons. - Rustling at dusk at the roof edge: bats. - A strong smell under the deck: skunks. - A big burrow beside the shed: groundhogs. - Quick scurrying at dawn and dusk: squirrels.
Baby season.
Around Somerville, most babies are born from about March through June. Mothers look for warm, dry spots like attics and chimneys. Never seal a hole while babies are still inside. Bat exclusion waits until pups can fly, usually by mid-August.
A year of wildlife in Somerville.
- Summer: highs near 82°F in Somerville. Animals roam at night. - Fall: animals hunt for winter dens. Seal gaps now. - Winter: lows near 22°F in Somerville. Animals den up in attics. - Spring: babies are born from about March through June. Don't seal while young are inside.
Raccoons.
Never handle one. Heavy thumps at night usually mean a raccoon. They tear open vents and roof edges.
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 Somerville, 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.
- 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. - Identify: figure out which animal it is.
Where animals get in.
- Gaps where the roof meets the wall. - Uncapped chimneys. - Crawl-space doors and foundation vents. - Under decks, porches and sheds. - Roof vents and soffit corners.
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.
- Wear gloves, a mask and old clothes. - Wet droppings down, then bag them. - Large attic messes are a job for pros. - Don’t sweep or vacuum droppings dry.
Keeping your yard less inviting.
- 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. - Trash: locking lids, or keep bins in the garage.
Wildlife myths.
- 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. - Out in daylight means rabid: not always; mothers forage by day.
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. Chimney swifts nest in chimneys in summer and leave in fall.
If an animal seems sick.
animal control or your local health department. Don't try to trap or touch it. Staggering, circling or acting unafraid can mean illness. Keep people and pets inside.
Pets and wildlife.
your vet if your pet tangles with a wild animal. Keep pets' rabies shots up to date. Bring pets in at night.
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.
- 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. - People and pets: wash with peroxide, baking soda and dish soap.
Babies found alone.
Hurt or clearly orphaned? 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.
Fencing that works.
- Climbers: an electric wire near the top stops raccoons. - Gardens: hardware cloth beats chicken wire. - Gates: keep gaps underneath to a couple of inches. - Diggers: bury wire mesh a foot down, bent outward.
Questions to ask before you sign.
- Where is it getting in? - How will you handle babies? - What happens to the animal? - What will you seal with? - Is cleanup included? - Which animal is it?
What affects the price
- Permit, relocation, or disposal rules in your state.
- Number of animals, since trapping is priced per animal.
- Trip fees for daily trap checks over multiple days.
- Species involved; skunks and raccoons cost more to handle.
- Warranty length on exclusion work and sealed points.
- Length of deck or shed perimeter needing buried mesh.
