If you have pest birds hanging around your pool, you know the problems they cause. They leave droppings everywhere, which means frequent (and expensive) pool cleanings and constant hosing down of walkways, railings and steps. If you live in Southern California, ducks can be a big problem around pools. So can pigeons and grackles.

Sometimes birds clean out their nests and drop their waste in and around a pool. They often do this to avoid drawing predators to their nests. Black birds will sometimes spit in a pool. Some homeowners have resorted to poisons and BB guns. Not a good idea if you have pets or kids around (it’s also illegal to kill or harm certain birds). Others have taken to placing rubber snakes around the pool. These can be initially traumatizing to small children, and some pets have a tendency to chew and eat them. There are effective bird control devices you can use that will keep pest birds away from your pool without risking danger to people, kids, birds or pets. They include:

Bird Sonics. Mounted under eaves, patio covers or gazebos, these bird repellent devices can keep pest birds away from your pool or spa. Bird sonics emit predator and distress calls that birds instinctively fee from. They work on a bird's natural 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 bird deterrents work well against pigeons, crows, starlings, swallows, gulls, woodpeckers, sparrows, grackles, cormorants and many other species. One commercially available sonic system blasts the sound of Peregrine falcons (a pigeon's dreaded enemy) defending their territory. Another system targets starlings and seagulls, emitting the sounds of predator hawk screeching and gulls under attack. The best sonic systems will regularly alter the pitch, frequency, timing and intensity of their sounds. This keeps pest birds from getting used to repetitive sounds. One popular system can emit distress and predator calls for as many as 22 types of birds. The calls are repeated once every fifteen minutes. Sonic bird deterrents are not harmful to birds, pets or humans. The sounds they emit merely resemble normal bird sounds.

Visual Scare Deterrents. These include Bird Scare Balloons, flash tape and twine. The balloons feature large predator eyes that make birds really nervous. Scare Bird Diverters use the same principle. They feature a giant predator eye and can be hung under eaves to frighten birds. To keep birds, geese and ducks away from pools, fill bird scare balloons one-fourth full of water, and the rest with air. The balloons will float around the pool with predator eyes and shiny reflective surfaces constantly in motion to keep birds away.

When using visual scare devices, it’s important to move them around occasionally to prevent swallows from getting used to them.

Scarecrows. Any pest birds that approach this device’s radius of protection get hit with a stunning but harmless blast of water. The sudden water blast, alarming sprinkler sound and realistic looking bird-like moving head "persuade" birds to stay away. Scarecrows are simple to set up and easy to use. They connect to almost any garden hose, yet they consume just 2 to 3 cups of water per spray. Scarecrows cover approximately 1,200 square feet with a stream that reaches out 35 feet and 45 feet wide. They work day and night for up to 6 months and deliver over 1,000 "firings" on a single 9-volt battery. For added versatility, scarecrows can be easily fine tuned to adjust both their sensitivity and coverage distance. Incidentally, kids and dogs love to play with these devices.

Mini Scarecrow. For smaller applications, say to keep pest birds away from walkways, pool steps, diving boards or railings, there's the Mini Scarecrow. It uses compressed air and sound to scatter pest birds and "convince" them to avoid the area. Like its big brother, the Mini comes to life the second a pest bird gets within 3 to 4 feet of its sensor. Unlike its larger brother, the Mini hits birds with a squeal and a harmless blast of air. You can easily adjust Mini's angle of detection and spray angle to zero in on trouble spots. Each can holds over 200 sprays.

Pest birds have pooped all over your new statue. They've covered your sign with "dried mayo," and someone has threatened to sue you for slipping on bird poop as they entered your property. You've had it with the invasion of these fine-feathered "friends." You're ready to stick your head out of your window and yell, "I'm mad as hell and I'm not going to take it anymore!"

Relax. There are many ways to scare birds away. And keep them away. Without resorting to poisons or firearms. They run the gamut from economical to high-tech. Most can be used in any location or circumstance. Best of all, they're humane and effective in discouraging a wide range of pest birds from landing, pooping and nesting on your property.

Since the economy is in a downturn, we'll start with the simplest, most economical bird guard--the Bird Scare Products. These "shoo" birds away by capitalizing on their fear of shiny things that jostle in the wind. They include iridescent reflective foil or flash tape, scare balloons, banners and the like that serve to create an “Optical Distraction Zone” for most pest birds. Some bird scare balloon chasers have giant eyes that look predatory and threatening. All are easy to install and won't harm birds. They're ideal for gazebos, overhangs, patios, vineyards, parks, pool and spa areas, boat docks and other open areas.

The Bird Diverter, uses scare-eye images to deter pest birds. Like the chaser, they're simple to install and surprisingly effective. Some bird diverters serve double duty, with iridescent foil eyes to scare birds by day and glow-in-the-dark on the flip side to shoo them away when it gets dark.

Last but not least are the higher tech solutions, bird deterrents that scare birds using sound.

When it comes to sound, today's sound bird deterrents can be quite effective. Some audio bird guards create shrill predator and bird distress calls to scare birds away. Others just produce annoying sounds that drive birds away. All are ideal for enclosed areas like parking garages, sheds and overhangs to deter a wide range of pest birds, including sparrows, starlings, pigeons, seagulls and larger birds.

So, if you're troubled by pest birds, you don't have to take it any more!

While most birds are loved by man, pest birds represent a significant and ongoing problem. According to the FAA, bird strikes cost civil aviation almost $500 million a year. Keep in mind that just one bird can destroy an expensive jet engine in just seconds. The fact is, bird strikes on military airfields endanger our troops, can jeopardize the mission and ruin equipment. It's easy to see why many people look for ways to scare birds away.

Growers don't much care for pest birds either. Native and non-native bird species have been known to cause crop losses in vineyards--typically 30 percent to as much as 100 percent. Pest birds can quickly devour seeds and ripening fruit. Many growers pull out all the stops to scare birds away.

In the cities and urban areas, pest birds can wreak havoc with building facades, statues, schools, public playgrounds and parks. Bird droppings can destroy the paint on cars and buildings. They leave an unsightly mess and can carry a number of communicable diseases. Diseases transmitted by birds include aspergillosis, salmonellosis, thrush, avian tuberculosis, coccidiosis, cryptococcoses, encephalitis, histoplasmosis, Newcastle disease, toxoplasmosis and West Nile virus. No wonder so many municipalities have spent considerable sums of money to scare birds away.

The feral pigeon is by far the most prolific urban pest bird in the world. Originally descended from the domesticated rock dove, they are now wild and live in close proximity to man. Feral pigeons are scavengers, scrounging for food in cities and town centers, where they are often eagerly fed by the general public. Feral pigeon populations are on the rise due to a lack of natural predators, the constant supply of food and their ability to breed year around.

Other pest birds include the house sparrow, the starling and the gull. Gulls are scavengers and feed from scraps of food in town centers as well as sewerage outlets and domestic garbage dumps. Starlings often gather in huge flocks where their droppings ruin structures and monuments. Small but still a nuisance are sparrows, which often clog rain gutters and downspouts, and frequently cause electrical equipment shorts and fires.

To scare birds away without harming them can prove to be quite a challenge. Fortunately, there are a number of pest bird deterrents that are available to humanely discourage birds from landing, roosting and nesting.

For pigeons and large birds, consider the use of the highly effective Bird Spike strip. Harmless to birds, the intimidating spikes simply discourage birds from landing. Some bird spikes are made of stainless steel, others use rigid unbreakable polycarbonate spikes (the poly spikes are less expensive).

For flat even areas, the Bird Spider has proven its worth as an effective pest bird deterrent. The spindly spider arms whip around in the wind to scare birds away. Spiders come in several diameters to deter various bird sizes. Harmless to birds, spiders are easy to maintain and easy to install. Similar to the spider, the motorized whirly-gig utilizes rotating arms to scare birds away. Ideal for parapet walls, roofs, signs, and billboards, some of these products are powered by batteries and others are even powered by solar energy.

Next up are the growing number of balloons and banners of iridescent reflective foil and shiny tape, which create an “Optical Distraction Zone.” Some of these bird scare products feature lifelike reflective predator eyes. Others have "day-glow" backsides to scare birds away at night. One of the many things that make these bird scare products so appealing is their low cost and easy installation. They're ideal for use on boat docks, pool areas, overhangs, gazebos, and other troublesome areas.

We know people get irritated whey they walk across a carpet, reach for a doorknob and get shocked. It's the same with birds. Electric Shock Bird Repellers have been used for years to scare birds away. Ideal for pigeons, seagulls and larger birds, these electrified tracks mildly zap birds that try to land. Easily mounted on ledges, signs, rooftops, and flat or curved surfaces, many electric tracks have a low profile tracks, so they can't be seen from below.

While screaming at birds or blasting loud horns can scare birds away, there are bird deterrents that use ultrasonic sounds that annoy birds--annoy them enough to discourage them from landing. These audio deterrents imitate distress calls and predator calls. They're ideal for enclosed areas like parking garages, overhangs and sheds, where  pigeons, sparrows, starlings or seagulls sometimes gather in flocks.

Farmers and growers have long used this next category of bird deterrents to scare birds away. Known as Foggers or Misters, these disperse a food-grade, non-lethal aerosol of methyl anthranilate. The chemical has been approved by the EPA and won't harm birds. It simply irritates birds that fly through it, convincing them to avoid the area. Some misting systems feature multiple remote spray nozzles to allow specific areas to be treated and pinpointed.
