Controlling Pesky Birds in Commercial Food Facilities

Canada geese are not typically a problem inside food facilities, but can cause significant nuisance problems outside of facilities. This previously migratory species now often overwinters in the U.S. wherever food is abundant. They nest at the edges of bodies of water, such as ponds or swamps, and around buildings near bodies of water. When large flocks of geese overrun an area, their large and numerous droppings quickly become a foul nuisance.

Prevention of Birds In and Around Facilities

Before embarking on any bird management plan, it is necessary to determine if there are any laws pertaining to the situation. Federal law protects all birds with the exception of the common pigeon, and some local laws might block certain methods of bird management. Be sure to check federal, state, and local laws and ordinances to see if they affect the bird species causing issues and consult with a pest control professional experienced in bird control. Working together, you can ensure you remain in compliance with these regulations.

The first step in preventing bird problems in a food facility is utilizing a pest control professional to conduct a thorough inspection of the building in order to determine if there are signs of birds, what species might be causing problems, and if there are any points of access birds could use to enter the building. The pest professional will closely inspect both the inside and outside of the structure with flashlights and mirrors to determine if changes should be made to better exclude birds. During this initial inspection process, it is crucial to have open communication between the service provider, the property owner, and building employees.

Because pest professionals only see a small window of activity, staff members who are present throughout the day are an invaluable resource for gaining intel on when and where pest birds are causing problems. The facility manager or owner must also be highly involved in the inspection and monitoring of pests so it is clear what vulnerabilities may be present in or around the structure, and what must be accomplished to eliminate them. Additionally, it should be noted that employees frequently contribute to the entry of pest birds into buildings and warehouses when exterior doors or windows are left open. Having a protocol in place that everyone is aware of and follows goes a long way in preventing birds and other pests from entering the structure.

That being said, birds are incredibly resourceful creatures and can enter buildings in a variety of ways. Any openings to the building, such as lofts, vents, or eaves must be blocked with wood, metal, glass, masonry, or plastic netting. Warehouse doorways used frequently throughout the day are common access points for birds. Installing clear plastic strips that touch the ground at the opening have proven effective at excluding birds, as these are seen by many bird species as impassable barriers.

Sealing the exterior of a structure and eliminating food or water sources in the immediate vicinity of the building are the best ways to prevent infestations. These types of methods, which focus on eliminating factors that could lead to pest problems before they take root, are part of an integrated pest management plan, also known as IPM. Frequently, these simple fixes are enough to manage pest birds.

Tactile, Auditory, and Visual Repellents

Equally important to excluding birds from entering the facility is eliminating roosting areas on top of or near the building. If possible, eliminate ledges or create a 45-degree slope on which birds will not be able to roost or nest. If this is not an option, there are three main types of repellents designed to affect a bird’s senses: tactile, auditory, and visual.
