House Sparrows
NuisanceWhat it is
Small nonnative birds that readily nest on buildings, signs, eaves, vents, and other structures. Accumulated droppings, nesting material, noise, and food contamination can create nuisance problems.
How to recognize it
Small brown-gray birds nesting in eaves, vents, and signs, with messy nest material.
Where you will find it
Buildings, signs, vents, and eaves.
Why it matters
Droppings and nest material cause sanitation problems and block vents and drains.
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.
