Summer’s finally here and you’re ready to invite friends, family and neighbors to your patio for a fun-filled BBQ. The last thing you need is bird poop all over your BBQ, patio cover, balcony and walkways. Or to have annoying birds dive bomb your gests and kids as they try to enjoy their outdoor summer treats.

Yes, there are bird poisons and you could whip out your trusty BB gun. But do you really want to subject kids and pets to such extreme, potentially hazardous measures? Also keep in mind that in many states and municipalities, it’s against the law to kill or harm certain birds. Banging pots and pans and shooting off firecrackers will scare birds away—but only for a little while. Unless you use permanent and effective bird control measures, they’ll come back in droves when they get a whiff of your outdoor cooking.

Fortunately, there are a number of effective bird proofing devices that will keep pest birds away from your patio and balcony. Measures you can employ without risking injury to kids, birds or pets. They include:

Visual Scare Deterrents. These are fairly economical and easy to attach to various areas of your balcony, patio, or gazebo. They include a variety of flash tape and reflective banners that reflect sunlight and crackle in the breeze. The audio/visual elements combine to create a distraction that makes pest birds feel uneasy. You can also get Bird Scare Balloons—beach ball sized bird deterrents emblazoned with large predator eyes. Birds really feel uncomfortable with these. Likewise for Bird Scare Diverters, which are bladder shaped deterrents that have a large eye on them.  Remember that birds are not dummies, so you’ll need to move them around occasionally to prevent the little critters from getting used to them.

Bird Sonics. These time-proven bird deterrents can be discretely installed on patio covers, under eaves or and inside gazebos. They can keep pest birds away from large outdoor areas by emitting predator and distress calls that birds instinctively hate. They capitalize on a bird's innate fear of predators, as well as their acutely sensitive hearing (birds can process sounds in 1/200th of a second; humans process sounds in 1/20th of a second).

Sonic devices will guard your patio and balcony against pigeons, crows, starlings, swallows, gulls, woodpeckers, sparrows, grackles, cormorants and many other types of birds. One of the most effective sonic systems broadcasts the sound of Peregrine falcons (a pigeon's dreaded enemy) defending their territory. Other systems will deter starlings and seagulls with the sounds of predator hawks screeching and gulls under attack. Try to get sonic bird control systems that alter the pitch, frequency, timing and intensity of the sounds they emit. You don’t want pest birds to get used to hearing the same sound over and over. One highly regarded system emits distress and predator calls for as many as 22 types of birds. The calls are cycled through every fifteen minutes. One thing to keep in mind is that sonic bird deterrents will not harm birds, pets or humans. The sounds they emit are normal bird sounds.

Scarecrows. These ingenious devices are basically motion-activated sprinklers that give pest birds a hefty blast of water the second they enter the preset radius of protection. The sudden blast of water, alarming sprinkler sound and realistic looking bird head is enough to convince most birds that this is not a hospitable area. Scarecrows connect to almost any garden hose, yet they consume just 2 to 3 cups of water per blast. They cover about 1,200 square feet with a stream that reaches out 35 feet and 45 feet wide. They stand guard 24/7 for up to 6 months and deliver over 1,000 "firings" on a single 9-volt battery. You can even fine-tune their sensitivity and coverage distance. By the way, kids and dogs love to play with these devices.

Hawk Decoys. Get one or two of these decoys, strategically place them around your patio or balcony and pest birds will stay away. You’ll need to move them around and reposition them from time to time for best effect. Hawks are the natural predators of most pest birds and they hunt during the day. Be sure to get the most realistic looking bird available.  And make sure they are quality fabricated of heavy-duty plastic so they stand up to the elements. Some decoys have a hollow bottom that allows them to be filled with sand for greater stability on windy days.

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.
