With spring almost upon us, pest birds will be scouting out new locations for nesting and roosting. They can do a lot of damage to your store. Here's one area of your store that may be particularly vulnerable and what you can do to protect it.
Problem: Store signage—whether it's constructed of glass, metal, plastic or even a composite material—is attractive to most pest birds. Signs are usually elevated and often have a number of nooks and crannies where birds can conceal themselves from predators. Birds also like the warmth many signs offer, which comes from the lighted bulbs inside. During daylight hours, sun filters into glass and plastic and acts like a solarium for birds, keeping them nice and toasty.
When birds build nests in signs, they leave droppings, feathers and other debris in and around them. This material is perfect kindling for starting a fire. But even if they don't start a fire, these materials are unsightly and block out light. Eventually, the droppings will eat into the signage materials and destroy the sign. Either way, you're faced with some very expensive repair and cleanup costs.
Associated with birds nesting in signs is the problem of bird droppings right below the sings. This can lead to dangerous slip-and-fall hazards for both employees and customers. The legal liability here can be ruinously expensive.
The Solution: The are a number of ways you can keep pest birds away from your signs. One of the best ways is to use bird netting. This is a far better alternative than bird poisons or BB guns—the former presents a health problem; the latter can leave holes in your sign.
Bird netting is humane and proven effective in excluding birds from signage. Birds like sparrows, starlings and pigeons can't penetrate the netting to land, so they simply move on to a more hospitable home. The best netting is Heavy-Duty Polyethylene Bird Netting. It's made from a U.V. stabilized mesh and comes in various stock sizes and custom cuts. Depending on the bird you're tying to keep out and the size of your sign, you have three choices: a 2-inch mesh, 1 1/8-inch mesh, and 3/4-inch mesh.
Look for bird netting that is ISO 1806 protocol mesh tested. It should also be flame resistant with a 270-degree F. melting point—some signs get really hot. You'll want your netting to last through hot and cold weather, so opt for bird netting that's rot-proof, non-conductive and stable in sub zero temperatures. One manufacturer offers bird netting that's fabricated using 6 monofilaments, each12/1000s of an inch thick. Twisted together to produce a sturdy twine, the monofilaments help give this net a breaking strength that exceeds 40 lbs. Bird Netting like this comes with a 10-year guarantee. This type of bird netting is very durable and often specified by architects.
For best results, you should install bird netting now, before pest birds begin arriving in the spring. In addition, the netting should be correctly installed (a qualified bird control expert can help you). Before installation, be sure to clean all contact surfaces of bird droppings, nesting materials, rust, peeling paint or other debris. Improperly installed bird netting can sag or droop, creating gaps that birds can work their way through.
