by Alex A. KecskesPest birds can be both a hazard and an expensive nuisance when they nest and gather in hangars, under overhangs, warehouses and other large covered areas. But thanks to bird netting, many of these problems can be avoided.Clearly the most obvious problem created by pest birds is their droppings. These can quickly clog gutters and down pipes. They can also cause ceilings, rooftop turbine ventilators, siding windows and doors to seize up. And they can rapidly deteriorate corrugated metal surfaces, block light sensors and security cameras. Left unchecked, these bird by-products can lead to structural damage and huge repair costs. Equally problematic, bird droppings deposited on entrances and fire escapes can create slip-and-fall hazards for maintenance crews, which can become a huge legal liability to public and private enterprises. Bird netting can solve these problems by keeping pest birds out using a proven humane method. Without bird netting, one would also have to contend with the incessant and irritating noise pest birds produce when they gather in sizeable numbers. And they do tend to gather in large commercial areas. In warehouses, for example, bird droppings can spoil finished products in loading bays and storage areas. They can severely stain and damage goods, and mar the appearance of costly finished goods and metal panels. Pest birds can also be a health hazard, carrying and transmitting any of 60 known diseases. Sparrows and Feral Pigeons can carry bacteria causing Salmonellosis. Feral Pigeons carry Ornithosis, which is similar to viral pneumonia. Birds, bird droppings and their nesting materials contain insects and mites. These insects can damage property, foods and fabrics stored in warehouses. Thankfully, bird netting offers an effective bird control solution that's ideal for a broad range of commercial uses. Bird netting can control many bird species and is often suggested as a bird deterrent by architects. Some netting is U.V. stabilized, flame resistant and rot and waterproof. It comes in different mesh sizes to control pest birds without trapping them. For large birds like pigeons and seagulls, a 1-1/8” to 2” mesh size is recommended. For smaller birds like sparrows and starlings, a smaller size mesh ¾” is recommended.Heavy-duty bird netting is made of high strength polyethylene. This type of bird netting is ideal for keeping pest birds from entering air hangars, garages, factories, warehouses, eaves, and canopies. Netting comes in a number of colors, including white, stone and black. Black bird netting offers natural U.V. protection and won't discolor when it gets dirty and dusty. Installed properly, this type of bird netting is virtually invisible.Sturdy knotted polyethylene bird netting comes in U.V. treated twine for long life and can have a burst strength as high as 40 pounds. Most of these nets are flame resistant and have a high melting point. Heavy-duty bird netting is ideal for use in warehouses, airplane hangars, canopies, overhangs and other large areas where pest birds need to be controlled. Covering an airplane hangar, warehouse or other large area with sufficient bird netting calls for thousands of square feet of netting and special lifts and power equipment. A job like this usually requires a professional bird control installer, if the bird netting is improperly installed, it will sag and droop. This will create gaps that allow pest birds to enter. A cable should be set up around the perimeter of the area being netted off, and the net attached to this cable.Bird netting is a wise investment for any facilities manager in charge of warehouses, hangars and large buildings where pest birds tend to gather. The yearly savings each year in property damage, damaged goods and health risks is worth the cost of any bird-netting project.
