Raccoon in Your Attic? Here’s What Ontario Law Says
By Husky Pest Control Technicians | Ontario, Canada | 5 min read
Key Legal Point: In Ontario, it is illegal to trap and relocate raccoons more than 1 kilometre from the capture site without a permit. Killing raccoons requires specific circumstances and authorization. Humane exclusion — making your home inaccessible — is the only fully legal DIY approach.
Raccoons are intelligent, adaptable, and remarkably destructive houseguests. A single raccoon in your attic can cause thousands of dollars in damage — tearing insulation, chewing wiring, contaminating insulation with urine and feces, and creating structural openings that invite other pests. If you hear thumping, scratching, or chattering noises overhead, especially at dusk or dawn, you likely have a raccoon problem.
What Ontario Law Says About Raccoon Removal
Raccoons in Ontario are protected under the Fish and Wildlife Conservation Act, 1997. This legislation governs how wildlife can be trapped, handled, and relocated.
The Key Rules:
- 1km relocation limit: Under Ontario Regulation 665/98, trappers may only relocate a live-trapped raccoon within 1 kilometre of its capture site. Relocating further requires authorization.
- Trapping requires a licence: Anyone trapping raccoons for hire must hold a valid Trapper’s Licence or work under one. Nuisance Wildlife Control Agents (NWCAs) are licensed for commercial wildlife removal.
- Killing is restricted: You may humanely kill a raccoon on your own property that is causing damage, but lethal methods must be humane and are subject to animal cruelty provisions under the Ontario SPCA Act and Criminal Code of Canada.
- Pup season restrictions: From April through August, female raccoons may have kits (babies). Ontario wildlife standards strongly discourage exclusion during active denning season to prevent separating mothers from young.
Signs You Have a Raccoon in Your Attic
- Heavy thumping or rolling sounds at night or early morning (raccoons are nocturnal)
- Chattering, crying, or screeching sounds (especially in spring — could indicate kits)
- Visible damage to soffits, fascia, vents, or roof shingles
- Strong ammonia odour from attic (urine accumulation)
- Latrines — raccoons designate specific spots for defecation; attic latrines are a serious health hazard
- Insulation disturbance visible through attic hatch
Health Risks: Raccoon Roundworm and Leptospirosis
Raccoon feces can contain Baylisascaris procyonis (raccoon roundworm), a parasite whose eggs can survive in soil and insulation for years. Ingestion or inhalation of these eggs can cause severe neurological damage in humans and is potentially fatal.
Raccoons can also carry leptospirosis (spread through urine), rabies, and distemper. Attic decontamination following raccoon removal is not optional — it’s a critical health and safety step that requires protective equipment and proper disposal of contaminated materials.
The Proper Removal Process
Inspection: Identify all entry points and determine if kits are present (especially critical April–August).
Humane exclusion or live trapping: Install one-way doors on entry points so raccoons can exit but not re-enter, or use live traps monitored twice daily as required by Ontario regulation.
Entry point sealing: All entry points sealed with heavy-gauge materials — raccoons can tear through rotted wood, thin metal, and standard mesh easily.
Attic decontamination: Removal and safe disposal of contaminated insulation, disinfection of affected areas, and restoration as required.

Frequently Asked Questions
Is it legal to trap and relocate a raccoon in Ontario?
You may live-trap a raccoon that is damaging your own property, but under Ontario’s Fish and Wildlife Conservation Act it must be released within 1 kilometre of where it was caught, within 24 hours. Relocating it farther, or trapping for hire, requires the proper licence or agent authorization.
What is the best way to get a raccoon out of my attic?
Humane exclusion is the most effective and fully legal approach: confirm there are no babies present, fit a one-way door so the raccoon can leave but not return, then seal the entry point. In spring and early summer there is often a mother with kits, which makes removal more complicated.
Will a raccoon leave my attic on its own?
Usually not, because an attic is a warm, safe, predator-free den, and a female that has chosen it for her litter will not leave until the kits can travel. The reliable fix is humane eviction and exclusion: confirm whether young are present, fit a one-way door so the raccoon can exit but not return, then seal the entry point so it cannot come back.
