Raccoon removal is part wildlife handling, part building repair. A removal company confirms whether there are young, lets the family leave through a one-way door or reunites the kits with their mother outside, then closes the entry with materials a raccoon can't tear through. Provincial rules limit how far a captured raccoon can be moved, and the droppings left behind carry health risks of their own.
This page covers signs of raccoons, what attracts them, the spring baby season, humane removal, relocation rules, roundworm and rabies, and repairing the entry points.
Signs of raccoons in the attic, chimney or under the deck
The City of Toronto lists the openings raccoons use: uncapped chimneys, loose shingles and openings in attics, roofs and eaves, garages and sheds, as well as the space under decks and other structures. The damage outside and the timing of the noise usually confirm a raccoon rather than a smaller animal.
- Heavy walking or thumping overhead that starts around dusk and returns before dawn.
- Chirping, crying or purring sounds from the attic or chimney in spring, a strong sign of kits.
- A roof vent pushed up or torn off, shingles lifted at the roof edge, or a soffit panel pulled down.
- Muddy paw prints or scratch marks on downspouts, siding, fences or trees near the roof.
- Knocked-over bins, torn garbage bags and a green bin pried open overnight.
- Piles of droppings on the roof, deck or woodpile, or in one corner of the attic.
What draws raccoons to a house: garbage, green bins, pet food and easy roof access
Raccoons settle where food and shelter are close together. Toronto Public Health asks residents not to feed raccoons or other wild animals, and the City recommends putting the green bin and garbage out on the morning of collection rather than the night before. Ontario's guidance adds a bungee cord or strap to keep lids tight on garbage and compost bins.
- Garbage and green bins stored where raccoons can tip them, or with loose or damaged lids.
- Pet food and water bowls left on the porch or deck overnight.
- Bird seed on the ground, fallen fruit and open compost.
- Tree branches and vines that give easy access to the roof.
- Uncapped chimneys, weak roof vents and loose soffits that offer a sheltered den.
- Open space under decks, porches and sheds.
Raccoon babies in the attic or chimney: spring timing and what not to do
Toronto advises making sure all raccoons have moved out before an opening is closed, especially between March and July, when there may be babies. A mother cut off from her kits will work hard to reach them again, often by tearing a fresh hole in the roof, and kits sealed inside die where they are.
For a raccoon in a chimney, Ontario's guidance says the easiest option is often to wait: after eight to ten weeks, the female and young leave and don't return. It also warns against smoking them out or pouring anything down the chimney, including naphtha flakes or mothballs, since adult raccoons can climb out easily but their young can't. Once the family is gone, a chimney cap keeps the next one out.
Humane raccoon removal: one-way doors, reuniting kits and sealing the entry
Our wildlife removal page explains the general exclusion process. With raccoons, a few steps matter most.
- The technician finds the den, often next to the entry hole or deep under the insulation, and checks for kits before anything is installed.
- When kits are present, one option is to wait until they can follow their mother out; another is to place them in a warm, protected box beside the entry so she can carry them to a new den.
- A heavy-duty one-way door goes over the main entry once only adults remain, so the raccoon can leave to feed but can't get back in.
- The one-way door stays in place until there are no signs of re-entry, and then the opening is closed permanently.
- Other weak spots on the roof are reinforced at the same time, because an evicted raccoon will often test the rest of the roofline.
- Soiled insulation and droppings are removed with protective equipment once the attic is empty.
Raccoon relocation rules in Ontario and Quebec: why you can't drive them to the country
Many homeowners picture trapping a raccoon and releasing it far away, but provincial rules point the other way. In Ontario, captured wildlife must be released within 1 kilometre of where it was caught and within 24 hours, and a wildlife removal business may capture and release a problem animal but not kill it. Moving animals also moves disease: Ontario reports that its 2015 raccoon rabies outbreak began when an animal was inadvertently moved into the province.
In Quebec, a landowner who captures a nuisance raccoon may release it on site, outside the building, with killing only as a last resort, and in municipalities around known raccoon rabies cases, moving or relocating live raccoons is prohibited. Whatever the province, a mother trapped and taken away leaves her kits behind to die, which is why exclusion is preferred over trapping in spring.
Raccoon roundworm and rabies: health risks from droppings, bites and sick raccoons
Raccoon droppings are more than a smell problem. HealthLink BC notes that waste from pet dogs, cats and raccoons is a common source of human roundworm infection, so keep children and pets away from raccoon latrines on decks, roofs and woodpiles. Toronto advises removing material contaminated with raccoon feces carefully and burning it, burying it or sending it to landfill, wearing protective equipment and treating surfaces with boiling water. A latrine in an attic is a job for a professional crew.
Raccoons are among the most common rabies carriers in Ontario, and Toronto Public Health calls them a high-risk vector for rabies transmission. Ontario reports no raccoon-variant cases detected since 2023, but the province still describes two forms of the disease to watch for: a dumb form, in which animals lose their fear of humans and become paralyzed, and a furious form, in which they become extremely excited and aggressive. Report a raccoon that seems sick to the provincial Wildlife Health Information Line, or to police in an emergency, and anyone bitten or scratched should wash the wound and contact a doctor or the local health unit right away.
Repairing raccoon entry points: roof vents, soffits, shingles and deck skirting
A raccoon that has used an opening once will push hard on the patch, so the repair has to be stronger than the original material. Quebec's wildlife guidance recommends mesh with 5-cm openings against raccoons, groundhogs and skunks. Roof work belongs to a roofer or the removal company's crew, not a homeowner on a ladder.
- Roof vents: replaced or fitted with a heavy metal guard fastened to the roof deck, not just to the vent cover.
- Soffits and fascia: damaged panels replaced and the corners reinforced where the soffit meets the roofline.
- Shingles and roof edges: lifted or torn sections repaired by a roofer, with the roof deck underneath checked for water damage.
- Chimneys: a sturdy, screened cap fastened to the flue once the chimney is confirmed empty.
- Decks, porches and sheds: heavy mesh skirting buried in the ground and bent outward, installed only after the space is empty.
- Attic: insulation restored and any chewed wiring checked by an electrician.
Raccoons: frequently asked questions
Will raccoons leave my attic on their own?
Sometimes, particularly once the kits are old enough to travel, but the opening stays and another raccoon can move in. Have the space checked to confirm it's empty, then get the entry repaired properly.
Can I use mothballs to drive raccoons out?
Ontario specifically warns against pouring naphtha flakes or mothballs down a chimney or smoking raccoons out, because the young can't escape the way adults can. Chemicals also contaminate the attic you'll have to clean, so ask a removal company before trying anything.
Can I trap the raccoon and release it at a park across town?
No. In Ontario, captured wildlife has to be released within 1 kilometre of where it was caught, and in parts of Quebec moving live raccoons is prohibited because of rabies. A trapped mother also leaves her kits behind.
How dangerous are raccoon droppings in the attic?
They can carry a roundworm that infects people, along with other germs, so never handle them bare-handed or stir up the dust. Keep children and pets away and have soiled insulation and latrines removed by a crew with protective equipment.
A raccoon is out during the day. Is it rabid?
Not necessarily, since a nursing mother may forage in daylight. Watch from a distance for the signs Ontario describes, such as no fear of people, paralysis or unusual aggression, and report it if you're concerned. Never approach it.
