You hear scratching. Maybe even some soft scuttling. It’s 2:00 a.m. and the ceiling above your bedroom is alive with movement. As much as you’d like to believe it’s your imagination, you know better. You’ve got a nightmare in the attic—and it’s not going away on its own.

Unwanted critters in the attic are more than just unsettling—they’re dangerous, destructive, and downright unhygienic. At Action Pest, we’ve helped countless homeowners with attic pest control, and we’ve seen just how quickly a small problem can spiral into a serious one. Whether it’s squirrels nesting in insulation, mice chewing through wires, or wasps setting up camp, spring and fall are peak seasons for attic invasions.

Here’s what you need to know about identifying and removing attic pests—and how to do it right the first time.

Why Your Attic Is a Target

Attics are warm, dark, and undisturbed—making them the perfect environment for pests. In fact, many critters don’t just find your attic by accident. They’re actively searching for safe, insulated spaces to nest, breed, and hide from predators or harsh weather.

When we perform pest inspections, some of the most common attic invaders we identify include:

  • Rodents like mice and rats, who gnaw through insulation and electrical wires.
  • Squirrels, often heard during the day as they come and go through roofline gaps.
  • Raccoons, heavy movers that cause extensive damage and leave behind strong odours.
  • Wasps and hornets, which can build nests in eaves and roof cavities.
  • Bats, which often enter through vents and can pose a serious health risk due to guano accumulation.

Signs You’ve Got Uninvited Guests

The earlier you catch an attic infestation, the better your outcome. Listen, look, and sniff—yes, sniff—for the following signs:

  • Noises at night or early morning, such as scratching, gnawing, or scampering.
  • Droppings and urine stains near insulation, HVAC systems, or beams.
  • Shredded materials used for nesting—paper, fibreglass, or even insulation.
  • Unpleasant odours, often ammonia-like or musky.
  • Visible entry points or chewed wood around vents, eaves, or roofing.

During professional attic pest control in Hamilton, we often find infestations that have gone undetected for months—sometimes even years—simply because homeowners didn’t know what signs to look for.

Why DIY Isn’t Enough

While hardware store traps or foam sealants might seem like quick fixes, they rarely solve the root problem. Many pests—especially rodents and raccoons—can chew right through these materials, and insects like wasps or bats may become aggressive if improperly disturbed.

Worse yet, some species are protected under Ontario wildlife laws and require humane removal and proper relocation. Attempting to remove certain animals without professional guidance can result in fines or injury.

Removing critters from the attic demands a strategic approach—one that includes inspection, species identification, removal, sanitation, and full prevention. That’s why homeowners turn to Action Pest: we don’t just deal with pests—we prevent them from coming back.
