Pigeons on the Warehouse Roof: Bird Control for Facilities

Why birds are a facility problem

Pigeon and sparrow droppings at dock doors and on rooflines are a slip hazard for staff, corrode metal and roofing surfaces, and show up as findings in third-party audits. Nests in vents, rafters and equipment add fire risk and contamination, and bird activity near open dock doors can bring droppings into the product-handling area.

For food-grade and audited facilities, visible bird activity is not just unsightly — it can threaten certification.

Exclusion beats cleanup

The durable fix is denying the perch and nest site, not repeatedly cleaning droppings. Netting seals off large areas like loading canopies and open rafters; spikes break up ledges, beams and signage edges where birds land; and screening closes nesting cavities and vent openings.

The right mix depends on the roofline, the species and how much pressure the site gets. A survey maps where birds actually roost and enter, then targets those points.

• Netting — large open areas, dock canopies, rafters.
• Spikes — ledges, beams, signage and pipe runs.
• Screening/exclusion — vents, cavities and nesting gaps.

The Will County logistics context

With CenterPoint Intermodal Center in Elwood and warehouse parks along I-55 and I-80 in Romeoville, Bolingbrook and Minooka, Will County is a major logistics hub where dock-door bird pressure is common. High truck traffic and frequently open doors give pigeons easy access, so a planned exclusion program protects both safety scores and audit results across these facilities.

Are the birds protected?

Common pest birds — pigeons, house sparrows and European starlings — are non-native and generally not protected, so exclusion and deterrence are appropriate. Many native songbirds and their active nests are protected under federal law, so a professional program is handled with those protections in mind, focusing on exclusion rather than harm.
