Bird control that takes away the roost

Pigeons, house sparrows and European starlings are non-native and can be excluded and deterred. Most native birds, including the swallows that build mud nests under eaves, are protected under federal law, so their active nests cannot be removed. Deterrents are installed before nesting season or after the young have left.

Physical exclusion and deterrents: netting for ledges, alcoves and under-structure spaces, spikes and post-and-wire systems on ledges and signs, and screening of vents and openings. The right mix depends on where they roost and nest.

Accumulated droppings can carry fungi and bacteria and become a problem when they dry and are disturbed. They are also acidic and damage roofs, solar panels, paint and equipment. Cleanup is done with protective equipment and the area sanitized.

The gap under rooftop panels is sheltered, warm and hard for predators to reach, so pigeons nest there in large numbers, leaving droppings, debris and noise. Mesh skirting around the panel edges closes the gap without touching the panels themselves.

Usually only briefly. Birds get used to static decoys and visual deterrents within days or weeks. Physical barriers that remove the roosting or nesting spot are what work long term.

Yes, and commercial sites are where most pigeon work happens: storefront ledges and signs, parking structures, loading docks, rooftop equipment and courtyards. Netting and spike installations are planned around access, lifts and business hours, and droppings cleanup at entrances is scheduled so customers and staff are not walking through it. The work pairs naturally with a commercial pest program where the building already has one.
