Wildlife we treat

Nuisance bird control

Scratching and chirping in the soffit, droppings accumulating on the exterior wall, insulation torn apart in the attic. You have uninvited tenants — and they're not paying rent.

Birds that move into building structures cause real damage: droppings contamination (histoplasmosis), insulation degradation, vent obstruction, fire risk from accumulated nesting materials, and persistent noise. The longer they stay, the greater the damage — and the cost.

Why birds move into your building

Birds seek safe shelter to nest and protect themselves from predators and weather. Damaged soffits, unprotected vents, gaps in siding and spaces under roofing are open invitations. Once a pair establishes itself, it returns to the same spot every year — and invites others to settle nearby.

Common species in the Outaouais and Ottawa

  • European starlings Extremely common. They squeeze into soffits, dryer vents and chimneys. Bulky nests that obstruct ventilation.
  • House sparrows Nest in the smallest openings: soffits, signs, exterior light fixtures. They return year after year.
  • Pigeons See our dedicated pigeon page for species-specific problems and our relocation solutions.
  • Swallows Mud nests under eaves and porches. Protected species during nesting — we intervene in full compliance with regulations.

Our 4-step process

  1. Inspection and assessment

    Species identification, locating all nesting points, assessing existing damage and entry points. Some species are protected by law — our intervention always complies with federal and provincial regulations.

  2. Exclusion and sealing

    Installation of exclusion devices that allow birds to exit without being able to return. Sealing of all entry points: soffits, vents, siding joints, masonry openings. We use durable materials that resist breakthrough attempts.

  3. Damage repair

    Birds damage insulation, ventilation ducts, soffits and siding. We repair structural damage caused by nesting and droppings contamination.

  4. Cleanup and decontamination

    Removal of nests, accumulated droppings and contaminated materials. Disinfection of affected areas. Bird droppings contain pathogens (histoplasmosis, cryptococcosis) — professional cleanup is important for occupant health.

Frequently asked questions

  • Can you intervene during nesting season?

    In Canada, the Migratory Birds Convention Act protects most wild birds during active nesting (generally April to August). We strictly comply with these regulations. For non-protected species (pigeons, starlings, house sparrows), intervention is possible year-round. We'll advise you on the best time to act.

  • Will the birds come back after sealing?

    Not through the same entry points — our sealing is designed to hold. However, birds may attempt to open new access points if the building has other weaknesses. That's why our inspection covers the entire building, not just the current entry point.

  • Are bird droppings really dangerous?

    Yes. Pigeon and starling droppings can contain the fungus Histoplasma capsulatum, which causes histoplasmosis (a respiratory disease). Dry droppings are particularly dangerous because contaminated dust disperses into the air. Cleanup must be done with proper protective equipment.

  • Can sealing be done in winter?

    Yes, and it's often the ideal time. Birds are less active in nesting and entry points are easier to identify when nests are empty. Winter sealing prevents spring nesting.

  • How much does an intervention cost?

    Cost depends on the extent of damage, number of entry points and accessibility (height, roof type). We provide a free, detailed estimate before any work begins.
