by Alex A. KecskesIn most states, food distribution centers must have a comprehensive, verifiable pest control program or risk being cited by health inspectors. Any evidence of pest infestation--like bird feathers--in a food distribution warehouse is a violation of the FD&C Act of 1938. Legal concerns aside, studies estimate that pest activity typically results in a 5% to 10% loss of stored food products. Can your distribution center sustain such losses in these tough economic times?Another bird problem created by pest birds is one of danger to employees. Birds can be a distraction to forklift and skip-loader operators when moving heavy loads near ceilings. Bird droppings can also create dangerous slip-and-fall hazards on smooth concrete floors. Finally, bird droppings can pose a significant health hazard, since they can carry and transmit any of 60 known diseases--including salmonellosis and ornithosis. Pest birds can be pretty clever when it comes to concealing themselves in food distribution centers. They can hide and build nests in the lofty areas near skylights and roof support beams. They can also seek shelter in walls and behind electrical boxes and light fixtures. When night rolls around and your distribution center is quiet and dark with only a single night watchmen to walk the floor, pest birds come alive and eat through packaged foods, stored grains and other consumable inventory. This not only results in food loss but a constant clean-up expense. As you undoubtedly know, pest birds are reluctant to leave once they’ve settled in. They like the security, the protection from the elements, and the steady food supply your distribution center offers them. So how do you get rid of birds? There are a number of effective and humane bird proofing strategies you can employ to solve your pest bird problem. Here are some of the most popular:Heavy-Duty Netting. Ideal for denying bird access in large commercial areas, the best netting is constructed of high-strength polyethylene to last for many years. This netting is U.V. stabilized, flame resistant and rot- and water-proof. One supplier offers bird netting that has a burst strength of up to 40 pounds and the ability to withstand extreme temperatures--from 250-degree Fahrenheit to "sub-zero." Better still, today’s bird netting comes in a variety of types and mesh sizes to exclude many different birds species. Larger birds like pigeons or seagulls can be blocked out using a 1-1/8-inch to 2-inch mesh size. If your facility is plagued by smaller birds like sparrows or starlings, a 3/4-inch mesh size will suffice. Mist Capture Bird Netting. If your distribution center only has a few pest birds that like to fly around at night, you might look into getting Mist Capture Bird Netting. Pest birds will not see this netting and fly into it. Once captured, they can be removed and released outside. The best netting in this category is fabricated of strong, UV-stabilized lightweight fiber. It typically comes in four sizes--7’x10’, 10’x20’, 10’x30’ and 10’x40’. The netting is effective for use against pigeons, grackles, starlings, swallows, gulls and sparrows. Air Treatment Systems. Effective for bird proofing large enclosed areas, Air Treatment Systems generate an invisible dry vapor of methylanthranilate, a grape extract that irritates birds’ trigeminal nerve and mucous membranes through entry in the eyes, nose or mouth. One manufacturer offers a system with a unique nozzle design that expels a super fine 5-micron particle size mist, which leaves no residue. Treated areas simply smell fresh and clean and have no grape smell. This advanced “always-on” air treatment system maintains a constant low-level scent to repel pest birds. It can be programmed for daily hours of operation and duty cycles. Best of all, the system needs no separate compressor for operation. Depending on the size of your distribution center, you can get air treatment systems that cover 50,000 to 150,000 cubic feet. The best air treatment systems are fully compliant with US Department of Labor, Occupational Safety and Health Administration (OSHA) workplace inhalation safety standards.
