NuisanceWhat it is
Small birds that may roost or nest on and in buildings. Pest concerns include droppings, nesting debris, noise, food contamination, and blocked vents or drainage areas.
How to recognize it

Where you will find it
Eaves, vents, signs, and outdoor structures.
Why it matters

What to do
- Do not feed birds around the property.
- Avoid disturbing droppings and dry sweeping them. Dust can carry disease organisms.
- Note where birds roost or nest and take photos.
- Contact a licensed professional. Many birds are protected by law, so nest and removal work should follow the rules.
When to call a professional
- Droppings or nests build up on roofs, vents, or equipment.
- Birds nest in or block vents or gutters.
- You manage a commercial property where droppings are a safety issue.
