What Are Pest Birds?
​
​While most birds are beneficial to the environment, certain species become pests when they roost or nest on homes and businesses. Pigeons, starlings, and sparrows are the most common nuisance birds in New Jersey, Pennsylvania, and Delaware. They create mess, noise, and health hazards, especially in urban and suburban areas.
Are Pest Birds Harmful?
​
Pest birds cause problems in multiple ways:
-
Droppings & Mess: Bird droppings are highly acidic, corroding building materials, vehicles, and outdoor furniture.
-
Health Hazards: Droppings can contain fungi and bacteria linked to diseases like histoplasmosis, salmonella, and E. coli.
-
Clogged Vents & Gutters: Nesting materials block ventilation systems, chimneys, and drains, leading to fire hazards and water damage.
-
Noise & Aggression: Large flocks create noise disturbances, and some species (like nesting starlings) can become aggressive.
-
Secondary Pests: Bird nests attract mites, ticks, and fleas, which can spread into the home.
Pest Birds Control
​
Bird problems require humane, professional solutions that discourage roosting without harming the animals.
-
Inspection: Identify nesting or roosting areas.
-
Exclusion: Seal openings around soffits, vents, and chimneys to block entry.
-
Deterrents: Install spikes, netting, wire, or visual deterrents to prevent perching.
-
Sanitation: Remove nests and disinfect contaminated areas.
-
Long-Term Maintenance: Ongoing monitoring to keep birds away permanently.
