Musky odors, cone shaped holes, torn skirting, thumping sounds at dusk, or a loose soil mound near your foundation confirm a skunk, raccoon, or groundhog infestation under your shed or deck. Ignoring wildlife under your home risks structural damage, foundation shifting, biohazard contamination, and legal violations under Ontario's Fish and Wildlife Conservation Act. Pestiseed's Ontario MNRF-licensed wildlife removal specialists provide free property inspections, same day service, and 24/7 emergency wildlife control across Toronto with humane one way door exclusion, full decontamination, and a 10 year exclusion warranty on every job. 

How to Tell What Animal Is Under Your Shed Without Seeing It 

A musky odour near your shed perimeter is often the first clue. Skunk smell or ammonia signals a latrine site nearby. Check the foundation corner for a burrow opening with loose soil mound around it. A small hole, about 3 inches wide, with clean edges points to groundhogs. Ragged edges on torn skirting near a perimeter gap mean raccoons forced their way in. Soil disturbance and excavated soil beside a tunnel entrance confirm active digging evidence. Listen at dusk activity and dawn activity for scratching sound or thumping sound from below. Nocturnal animals like skunks leave urine traces and territorial marking near the den access point. Look for a paw print or hand shaped print with five toes in a soft mud track near the ground level gap. Narrow scat with a pointed scat shape near a yard hole confirms weasels. Blunt claws in a soil impression near the crawl space mean groundhogs. Paired oval print tracks in soft ground along the deck underside edge identify opossums.

Animals Most Likely Under Toronto Sheds and Decks 

Skunks

A striped skunk (Mephitis mephitis) digs a skunk burrow with a clean edged hole about 3 to 4 inches wide. This nocturnal forager picks shed and deck spots near your Toronto green bin. The sulphur odour from skunk spray comes from a thiol compound that causes temporary blindness and anemia risk in pets. Denning season runs February through April, with 4 to 6 babies staying 6 to 8 weeks as dependent young. A wildlife technician installs a one way door for safe skunk removal.

Raccoons 

The Toronto raccoon population holds the highest density in North America. A raccoon latrine carries Baylisascaris procyonis roundworm, turning your play area into a public health risk. Ontario Reg 665 limits relocation to 1 kilometre, making illegal relocation a fineable offense. A licensed trapper uses a one way door for raccoon exclusion. Torn skirting and peeled grass signal active grub foraging overnight.

Groundhog 

A groundhog (Marmota monax) moves 35 pounds of soil, building a tunnel system with multiple entrances. That burrow network causes foundation damage, deck post shifts, and slab undermining. Freeze thaw cycles through Toronto winters speed up uneven settling. Their active season runs April through September. A 6 inch hole with a loose soil mound near your concrete footing needs a foundation inspection fast.

How Much Damage Is Actually Happening Right Now Risk by Animal Type 

Foundation and Deck Integrity 

Soil displacement under a concrete slab turns into serious structural damage fast. Burrowing impact beside a deck post cracks the concrete pad and weakens the footing. Toronto winters drive freeze thaw cycles that trigger frost heave and split settlement cracks open wider each year. Moisture intrusion at every entry point feeds wood rot deep into the deck, speeding up rot acceleration. Subgrade erosion and soil erosion together build structural instability that pushes repair cost into thousands. Get a written assessment and structural report before deck replacement becomes your only option. 

When a Wildlife Problem Becomes a Health Code Issue 

Raccoon roundworm (Baylisascaris procyonis) drops fecal matter across a 3 metre radius from any active latrine site. Larval migration drives disease transmission through soil contamination into play areas where kids run daily. Toronto Public Health treats active raccoon latrine zones as a biohazard requiring a full decontamination protocol. Skunk rabies stays a confirmed rabies vector under Ontario MNRF reporting rules. Ignored biological contamination ruins indoor air quality and needs professional odour remediation. Call a licensed exterminator for a wildlife inspection and complete decontamination service. 

What Ontario Law Says About Removing Wildlife From Your Property 

The Ontario Fish and Wildlife Conservation Act (FWCA) governs all wildlife regulation in Toronto. Ontario Reg 665 caps relocation distance at 1 kilometre, making illegal relocation a fineable offense. A licensed trapper with a wildlife removal licence handles trap and release legally. Kill trap restriction rules ban DIY traps without a trapping permit.

The baby season runs March through July under the FWCA protection window. A licensed exterminator installs a one way door as the only legal passive exclusion method. Mother separation from dependent young breaks provincial regulation. Property owner responsibility includes bylaw compliance with Ontario MNRF rules and the City of Toronto bylaw.

Should You Handle This Yourself or Call a Licensed Exterminator

When DIY Makes Sense

DIY removal works for a single animal using one single entry point during a denning period. A perimeter check confirms no young present before any one way door goes up. Door sizing and door placement matter for species specific door success. Groundhog early stage light excavation gets fixed with galvanized mesh bent at a 90 degree bend at 12 inch depth as an underground barrier. Run a full audit and entry point mapping before calling it done. Summer removal and autumn removal are the safest windows for homeowner effort.

When DIY Creates More Risk Than It Solves

Skunk exclusion risk turns into a spray risk the moment a startled animal fires. Thiol exposure from human spray sends people to a hospital visit and causes temporary blindness and anemia risk. A raccoon latrine needs biohazard handling, not bare hands. Roundworm exposure without protective equipment leads to serious biohazard cleanup costs. Incorrect door size or wrong placement creates re entry and a return animal fast. Chicken wire failure and degraded mesh let a raccoon breach any weak seal. Failed seal over an active sealed den causes decomposition and a serious odour problem. DIY failure always leads to cost escalation and delayed professional intervention.

How to AnimalProof Your Shed and Deck in Toronto

An L shaped barrier of 16 gauge welded wire mesh buried at 12 inch depth with a 90 degree outward bend blocks every burrower. Chicken wire failure and mesh degradation guarantee a raccoon breach, so use galvanized steel mesh only. Fix every corner treatment gap since corner failure creates a secondary entry fast. A full perimeter seal with no missed entry point delivers real 10 year exclusion.

Follow a seasonal schedule starting with a February inspection for fresh digging signs before pre denning begins. A May inspection catches active young early. Lock your wildlife resistant lid to meet the City of Toronto bylaw on attractant control. Stop outdoor pet feeding at dusk. An October inspection closes every winter shelter gap. Skip the ultrasonic repeller since peer reviewed evidence confirms repeller ineffectiveness on any denning animal.
