It usually starts the same way: you’re relaxing and you hear it—scratching, scurrying, or a heavy thump-thump under the deck. Your brain immediately goes, “Please don’t be a raccoon.”
If you live in Toronto or the GTA, you’re not imagining it. Decks are one of the most common outdoor trouble spots for raccoons, squirrels, and rats or mice—especially around older homes with small perimeter gaps, shifting soil, and damaged lattice. And while it’s tempting to try a quick fix, under-deck issues rarely stay “small.” The long-term solution almost always includes two parts:
(1) removing the animal (or controlling rodents) and (2) excluding access points so a new animal doesn’t move in next week.
Icon Pest serves Toronto and the GTA with humane wildlife removal for raccoons and squirrels, plus professional rodent control using lethal methods for rats and mice—paired with sealing and prevention so the space under your deck stops being a shelter.
Why Decks Attract Raccoons, Squirrels, and Rodents
From an animal’s point of view, a deck is a ready-made hideout: it’s dry, protected from wind, out of sight, and often close to food and water. Add one loose lattice panel or a gap near the stairs and it becomes an easy entry point.
- Shelter and warmth: under-deck spaces stay calmer than open yards, especially at night.
- Easy entry routes: broken lattice, gaps along edges, and soft soil make access simple.
- Food nearby: garbage, compost, BBQ grease, fallen fruit, bird seed, and pet food.
- Quiet nesting space: wildlife often chooses under-deck areas as den sites, especially during baby season.
Common signs homeowners notice include scratching or scurrying sounds, heavy movement at night, droppings near deck edges, digging along the perimeter, damaged lattice, chewed wood, and musty odours that linger near the deck. If you’re seeing multiple signs, you’re likely dealing with an active under-deck issue—not a one-time visit.

What Can Go Wrong If You Ignore It
A common misconception is: “They’re outside, so it’s fine.” Under-deck activity can escalate quickly, and some of the most expensive damage isn’t visible until later.
- Structural damage: raccoons can dig and shift soil; squirrels and rodents chew; lattice and edges weaken over time.
- Gnawing hazards: rats and mice can gnaw on materials (including wiring), increasing risk and repeat issues.
- Contamination: droppings and urine can cause odours and hygiene concerns—especially with kids or pets in the yard.
- Secondary pests: wildlife activity can attract insects and parasites.
- Safety risk: cornered animals can bite or scratch; DIY attempts often increase risk for homeowners.
Different animals also leave different ‘fingerprints.’ Raccoons tend to be louder at night and may dig. Squirrels are fast, active, and often chew. Rats and mice use hidden travel paths, reproduce quickly, and commonly move from outside into the structure when gaps are available.

1) Detailed inspection
A proper fix starts with identifying what species is present, where it’s entering/exiting, and what conditions are attracting it. Technicians typically check the deck perimeter, soil edges, foundation lines, vents, nearby sheds, and any compromised lattice or gaps. You should also expect clear findings and a recommended plan before work begins.
2) Species-specific plan
Under-deck problems aren’t one-size-fits-all. The plan should reflect the animal, the activity level, and whether babies may be present.
- Raccoons and squirrels: handled with humane wildlife removal methods plus prevention steps.
- Rats and mice: controlled using professional lethal methods as part of extermination and removal, paired with exclusion to prevent re-entry.
3) Exclusion and deck protection
This is where long-term results come from. Even if an animal leaves today, an open gap means another one can move in tomorrow. Exclusion typically includes sealing access points, reinforcing weak perimeter areas, and installing durable screening/barriers where wildlife commonly squeezes in. The goal is simple: make the space under your deck unavailable for shelter.
4) Clean-up guidance and follow-up
Where appropriate, you may receive advice (or service options) for cleanup/sanitization and simple changes that reduce attractants—like securing garbage, removing clutter, and managing outdoor food sources. Follow-up support may be available depending on the service and warranty terms.
Targeted Solutions for Each Pest Type Under Decks
Raccoon removal from decks
If you’re hearing heavy movement at night, noticing disturbed soil, or seeing obvious entry activity under the deck, raccoons are a strong suspect. The best results typically come from humane removal plus raccoon-proofing/exclusion so re-entry is no longer possible.
Squirrel removal around decks
Squirrels may use deck cavities as a staging spot and then move between fences, rooflines, sheds, and other structures. Because chewing is a risk, successful squirrel work usually combines humane removal with prevention to reduce repeat nesting.
Rat and mice control under deck
Droppings, burrows along the perimeter, and gnaw marks often point to rodents. Under-deck rodent activity can become a pathway into the home if gaps exist. A practical rodent solution includes finding access points and travel routes, professional lethal rodent control (rats/mice), and exclusion to prevent return under the deck or entry into the structure.
Plans, Pricing Transparency, and Seasonal Options for GTA Homeowners
Homeowners want two things: a solution that works and pricing that feels clear. Icon Pest emphasizes transparent recommendations and published plan options for recurring issues (especially rodent pressure).
If you’re requesting service, it’s reasonable to ask what the plan includes (inspection, visits, follow-up), what exclusions are recommended and why, what warranty terms apply (if any), and what seasonal offers or promotions are currently available. This keeps expectations aligned and helps you compare options fairly.
Frequently Asked Questions
Q1: Should I block the hole under my deck right away?
Usually, no—at least not until you’re sure the animal is out. Sealing an entry while an animal (or babies) are still inside can create bigger problems: damage, odours, and distressed wildlife. Inspection first is the safer approach.
Q2: What’s the fastest way to stop raccoons from coming back?
Exclusion. Removing the animal without closing entry points often means the next raccoon simply takes over the same sheltered space.
Q3: Do store-bought repellents work for under-deck pests?
They can help temporarily in some cases, but they usually don’t solve an active denning or nesting situation. If the area stays open and attractive, the problem often returns.
Q4: Is rodent control humane?
For rats and mice, professional control typically uses lethal methods. The long-term goal is to remove activity and prevent re-entry with sealing and exterior prevention so new rodents don’t replace them.
When to Call Icon Pest for Under-Deck Pest Problems
It’s time to call if you notice multiple days of noise or activity under the deck, animals entering/exiting from deck gaps, damage to lattice/wood or digging along the perimeter, or droppings and strong odours near the deck.
Don’t wait until the issue spreads to the shed, garage, or inside the home. Early action is usually easier and more cost-effective—especially when exclusion is done properly the first time.
