How to Set Up Bird Barriers to Get Rid of Pest Birds

By Alex A. Kecskes

You’ve got a pest bird problem, and the owner of the commercial building has instructed you to solve the problem--in other words, get rid of the birds! As an astute and experienced property manager, you’ve read about various bird proofing devices and methods. You also know that the owner wants you to use non-lethal means to keep birds away from the property.

Before we go into the various deterrents, you’ll need to walk around the property to determine what types of birds have invaded the premises and where they tend to perch, roost or nest. Note also, the likely places they could choose to move, were you to block access or bird proof these areas. Keep in mind that the most effective way to deter pest birds is to consider all possible perching, roosting and nesting areas.  Birds are clever and will quickly adapt to barriers and devices you erect. Sometimes, it helps to take photos of all possible areas bird might use, and to show these areas to a bird control professional.

Having evaluated your premises and determined the “what and where” of your bird problem, it’s time to consider some specific bird control measures. Let’s start with the most popular of pest bird deterrents, the Bird Spike.

To begin with, Stainless Steel Bird Spikes are the most durable. Ideal for deterring large pest birds like pigeons, crows, and gulls, they take away a bird’s ability to land and perch. Bird spikes should be mounted on ledges, I-beams, parapet walls, conduits and signs--wherever pest birds gather before the settle in to nest. Stainless steel spikes come in rows of spiked strips that are 3-, 5- and 8-inches wide. To help you determine the level of protection these spiked strips provide, the 8-inch spikes will give you 8 to 10 inches of deterrence on a 10-inch wide ledge. The best stainless steel bird spikes feature a “no-nest” design with no-gap spacing to keep birds from defeating them.

When installing bird spikes, follow these procedures: Use the staggered pre-drilled holes at the base of the spikes to nail or screw them into place. If you intend to glue them down, use construction-grade adhesives in the glue trough provided in better quality spikes. Better spikes will also feature breakaway notches to bird proof smaller areas. Leave no more than a 1-inch gap on either side of the spike to keep birds from sneaking around them. If you intend to mount bird spikes on a pipe or conduit, use a 1-inch spike to cover 1 to 2 inches and secure each spike with common hose clamps, nylon ties or wire.

Another popular bird proofing device used by commercial building owners is the Bird Spider. These deterrents feature spindly arms that whip about in the breeze to keep pest birds from landing anywhere near them. If you have birds nesting on AC units, water towers, electrical junction boxes and similar flat areas, mount a bird spider on top of these landing zones. They will keep pigeons, seagulls and larger birds from settling in on these areas. Bird spiders come in 2-, 4-, 6- and 8-foot models to provide increasingly wider areas of deterrence. When installing bird spiders, be sure the “tips” of the spider’s arms reach out several inches over the outside surface(s). Allow the arms to move freely with the tips no more than 2 or 3 inches above the mounting surface. When using glue to mount the spider, use the PVC adapter (provided by better bird spiders). If you’re installing more than one spider, position them 6 to 8 inches from arm-tip to arm-tip.

One last advisory note: Before installing bird barriers, dry up any water-damp areas and remove any loose rust, peeling paint, bird droppings, feathers and nesting materials. Birds will be drawn to the familiar scent of their species and regard the area a hospitable. Be sure to use commercial disinfecting cleaning agents to prevent installation crews from being exposed to the many airborne diseases carried by birds and their droppings. Use eye and respiratory protection if the area is heavily contaminated with droppings.
