Birds and Bats in Warehouses: A Logistics Nightmare

HWCS Expert Team

In the logistics industry, a clean facility is a profitable facility. Large distribution centers with high ceilings and open loading docks are prime targets for wildlife. A sparrow nesting in the rafters or a bat colony roosting above the loading bay isn’t just a nuisance—it’s a direct threat to your inventory and your certifications.

The Cost of Contamination

For warehouses storing food, pharmaceuticals, or packaging materials, “zero tolerance” is the standard.

  • Droppings on Product: Birds roosting on fire suppression pipes drop waste directly onto pallets below. Even if the product is sealed, the packaging is contaminated. This leads to rejected shipments and lost contracts.
  • Audit Failure: Third-party audits (AIB, BRC, SQF) heavily penalize evidence of pest activity. A bird flying through the facility during an audit is an automatic red flag.

Why They Get In

  • Open Docks: Loading docks are often left open for hours. Birds fly in seeking warmth or food crumbs.
  • Structural Gaps: Metal warehouses often have small gaps where the roof meets the wall, perfect for bats.
  • Canopies: The overhangs above loading docks are favorite nesting spots for swallows and pigeons.

Solutions for High Ceilings

1. Mist Netting

In large open spaces, we use ultra-fine mist nets (temporarily) to safely capture birds flying in the rafters. They are then removed and released.

2. Exclusion Netting

For a permanent solution, we install heavy-duty exclusion netting across the entire ceiling structure or under canopies. This physically blocks birds from landing on pipes or beams, forcing them to go elsewhere.

3. High-Speed Doors / Air Curtains

We recommend installing air curtains or high-speed roll-up doors to minimize the time the facility is open to the outdoors.

Don’t let a sparrow ruin your safety rating. HWCS has the lifts and certifications to handle high-altitude wildlife control in commercial facilities.
