Starlings Invade Indianapolis: Bird Proofing with Bird Netting Might Have Saved the City

by Alex A. Kecskes

During a recent Indianapolis winter and spring, flocks of pest birds swooped down upon the city, dropping their “loads” on office windows, covering everything, it seemed, with brown splotches of disease-carrying droppings. Starlings by the thousands coated the city’s prized Soldiers and Sailors monument, as well as the sidewalks with droppings that crunched disgustingly under every pedestrian footfall. Many residents of the proud city were forced to remove their shoes before entering their homes, letting their shoes sit outside doorsteps and entrances, lest they contaminate their homes with the smelly droppings. For the most part, residents and visitors to the city found themselves tiptoeing around the droppings and holding their breath to avoid any of the 60 known diseases--including histoplasmosis or bird flu--carried by bird droppings.

If only the City Fathers had implemented effective bird proofing measures before their starling invasion. Chief among such measures would have been Bird Netting.

One of the best types of netting to use is Heavy-Duty Polyethylene Bird Netting.  Fabricated from a U.V.-stabilized mesh and available in various stock sizes and custom cuts, Heavy-Duty Poly netting is easily installed and blankets key areas of a structure--those most likely to attract pest birds--with an effective bird barrier. For smaller birds like starlings, a 3/4-inch mesh would do the trick. Some manufacturers offer this type of netting in a variety of colors to blend in aesthetically with the structure or building. This type of bird netting is ISO 1806 protocol mesh tested, flame resistant, rot-proof, and waterproof. Depending on the location, one might even consider getting non-conductive netting, which won’t interfere with electrical wiring or cell phone, dish and other RF antenna systems.

Another type of bird netting that has been proven effective as a bird guard is No Knot Bird Netting. This netting is nearly 70 percent stronger than conventional knotted polyethylene netting and about 30 percent lighter, so it’s less expensive to ship and easier to handle. It also has a higher melting point than regular knotted polyethylene netting. Ideal for larger, horizontal applications, No Knot netting doesn’t need to be pulled into shape, which is often a requirement of ordinary knotted poly netting. No-Knot bird netting is available in various mesh sizes, including a 3/4-inch mesh to stop smaller birds like sparrows and starlings. Made of a multi-strand polypropylene fiber that's highly resistant to heat and many chemicals, No Knot netting meets ISO 1806 Protocols. It will not rot, absorb water, or mildew. It even contains U.V. inhibitors to tolerate high temperatures to 338F.

When installing any kind of bird netting, leave no gaps, openings, wrinkles or excessive sag in the netting. Most bird netting can be easily cut to size and shaped using scissors. Before cutting, allow extra netting for perimeter fastening and overlap seams (6" min. for both). Finally, be sure you cut a larger piece of netting than what's needed for the job.

Before installing any bird netting, make sure the surface is clean and dry. Remove bird droppings, feathers and nesting materials. (Birds are attracted to this debris and “zero in” on the area thinking it’s safe.) Use commercial disinfecting cleaning agents to prevent exposure to any of the 60 known airborne diseases caused by birds. You should also use eye and respiratory protection if the area is heavily contaminated with bird droppings.
