Pigeon Control—A Must for Commercial Property Managers

Birdproofpigeonspikes

By Alex A. Kecskes

One of the many concerns facing today’s property managers is pigeon control. Pigeons are pest birds that remain unprotected by the Migratory Bird Treaty Act of 1918. They can cause property managers a lot of grief.

So what attracts pest pigeons to a commercial building, its edifices and rooftops? A combination of factors. First off, commercial buildings usually offer covered areas that provide shelter from the elements. Things like rooftop AC units, electrical boxes, and ducting offer ideal places to nest and roost. Ledges and parapet walls offer high altitude perches for scouting predators and prey, especially if they overlook trash bins and dipsy-dumpsters.

Also, if your commercial building is the only one in the area offering such vantage points, it will attract flocks of pest pigeons. Another attractive feature of your building may be that it lies close to ponds, fields, and electrical wires. And if you’re unlucky enough to have a flock of pigeons already nesting on your building, the droppings will attract other pigeons, making your building a prime gathering spot. In general, pigeons will be strongly attracted to nesting spots they have already claimed as their own.

Without effective pigeon control measures, a pest pigeon infestation can result in costly and repetitive clean-ups. Long-term infestations. Can severely damage a commercial building’s facades, sills, parapet walls, roofing, water drainage systems and rooftop AC units. The annual damage/repair/cleanup cost of pest birds to commercial buildings is estimated to be in the hundreds of millions of dollars.

Getting Pigeons Out of Your Commercial Building



Pigeons-on-a-roof

By Alex A. Kecskes

If you own a commercial building, you no doubt have had problems with pigeons. In most cases, the larger the building, the bigger the problem. For strip malls, commercial centers, warehouses and other large structures, pigeons can cause all sorts of headaches for property managers and property owners.


If your building has a flat roof, pigeon debris, feathers and droppings can damage AC units, ventilators and drainage areas.  Pigeons love to gather around rooftop equipment, and as you know, AC units are not cheap. They cost plenty to maintain and repair.


Without proper pigeon control, pigeon debris can stop up rain vents and gutters, causing flooding.  Hundreds or even thousands of gallons of water trapped on a long flat roof can lead to structural problems and ultimately roof collapse. Once this occurs, you have a huge problem in terms of damage to inventory inside a building. 

Whether your building is covered by a roof made of wood shingles or tiles, pigeons waste can be highly destructive.  The acidic content of pigeon droppings can eat into the sub-roofing materials and eventually cause leaks. Bird droppings can also deface and damage your expensive signage—whether your signs are fabricated of metal, wood or plastic. Pigeons can also create an image problem. Bird droppings on entryways, walkways, display windows, benches, umbrellas and nearby lampposts can be a real turn off (and costly daily cleanups for you).

Fortunately, there are a variety of effective pigeon control methods you can employ to keep pigeons from returning to your commercial building or strip mall.  Before you install these measures, you’ll no doubt be faced with cleanup efforts. Keep in mind that contact with pigeon droppings may pose a health risk. These droppings have been known to cause such diseases as histoplasmosis, cryptococcosis, and psittacosis. So during any clean-up effort, precautions should be taken to protect the public as well as work crews. The use of disposable gloves, eye protection and facemasks are recommended. If clean-up crews are working in enclosed areas, such as attics, respirators should be used.

If you only have an occasional pigeon problem, consider installing a Bird Motel in areas most frequented by pest pigeons. These catch-and-release pigeon control motels are humane and allow you to safely relocate those few stubborn pigeons that simply won’t go away. Bird motels can be placed virtually anywhere pigeons like to gather. The best motels feature an easy-access door and are made of galvanized wire so they won't rust or corrode if left on rooftops.

If you’re being inundated with pest pigeons, you need the granddaddy of pigeon deterrents: the Pigeon Spike. These pigeon control devices have proven themselves time and again in a wide range of commercial applications. Pigeon spikes work because, there’s simply no way birds can negotiate a landing on or near them. The blunted spikes are harmless to birds and maintenance crews. Spikes come in either rigid U.V.-resistant unbreakable polycarbonate or the longer-lasting, slightly more expensive stainless steel models. You can even get spikes in a variety of colors--including white, tan, gray, black, brown, brick red and crystal clear. The spikes are easily glued or screwed to any surface.

Urban Areas Need Pigeon Control

Pigeon-control-products-that-work
By Arlene Connelly

Many urban dwellers are unaware that more than 60 human diseases — including avian flu, salmonella, E coli and West Nile virus — are related to pigeons, other pest birds and their droppings. Besides being a public health issue in many cities, they often create a safety hazard for pedestrians, and they carry dangerous parasites and harmful bacteria. Some of these illnesses can even be fatal to humans; they can be contracted through contact with the skin and exposure through inhalation as people go about their daily activities.

Why pest pigeons are especially dangerous

Pigeons are generally considered to be “the number one bird pest” in America today, their numbers are increasing, and their nesting instincts are strong. They usually mate for life, live in communal flocks that travel together, and tend to roost where they can find adequate food and shelter. Along with that, experts in the field now consider pigeons to be a genuine “urban menace,” threatening the quality of life in America’s great cities, including San Francisco, Chicago and New York.

Pigeon droppings can be found on walkways, roofs, window ledges and the sides of some of our finest buildings— anyplace these birds can access. This is especially dangerous around air vents and areas that surround water sources; the germs they carry can easily be transmitted to humans, especially those with a weakened immune system. They also attract insects that can spread disease as well, creating serious liability issues for businesses and restaurateurs.

The corrosive affect of pest pigeon droppings results in extensive and expensive damage to our public buildings and monuments, and they can cause a serious disaster like the collapse of the Minnesota Bridge. Feathers, droppings and nest paraphernalia can also be sucked into pipes and vents, creating a fire hazard in a city’s high-rise buildings where people work and live.

Today, Bird-B-Gone sets the standard for urban pigeon control, their products are humane and easy to install, and they require little maintenance. If you live in an urban environment or are responsible for building maintenance in one of our country’s fine cities, you can choose from many options for complete pigeon control.

Sound deterrents are often used to deter pest pigeons, and since they will soon become used to hearing one repetitious sound, you will want to use a device that features the sounds of predators and birds in distress with variations, which is more effective.  Good sound bird deterrents will use state-of-the art technology to provide easy volume adjustment, and it is also an inexpensive way to keep these birds away from your building. The system’s rigid construction makes it resistant to sun and weather, and you can easily adapt this device to your particular situation. It provides the distress calls of 22 types of birds and comes with an internal speaker; you can also connect four external speakers to the system to reduce the probability of damage to your building and increase your coverage area as well.

Visual bird deterrents are another good alternative

Visual bird deterrents are used to repel pest pigeons and other birds.  For example, The scare balloon is an “inflatable scare device” that confuses and deters pigeons with its lifelike predator markings and mysterious eyes they will avoid as they move on to a more appealing location.

The Scare Eye Diverter has an iridescent foil eye to protect your building from pigeons during the day and a glow-in-the-dark back to keep them away after the sun goes down. You can also use flash tape, made from iridescent red foil, to create what bird control experts call “an optical distraction zone” to do drive pigeons away.

Some pigeon control devices make it difficult for pigeons to land

Roost inhibitors, which are quite effective in keeping pest pigeons away from roofs, beams, ledges and various other surfaces, are probably the best-known methods of pigeon control, and they include bird spikes and bird netting. Bird spikes are available in two varieties and various colors and sizes to solve your pigeon control problem. Made from unbreakable polycarbonate, the plastic spikes are very strong and rigid, and the marine-grade stainless steel spikes are also available.

The polyethylene knotted bird netting in Bird-B-Gone’s product line is a favorite with architects because of its durability in all kinds of weather conditions. It deters pest pigeons and all species of birds from landing, comes with a 10-year guarantee, and is very affordable in these budget-conscious times.

The bird repeller sweeps pigeons away with its 5 ft radius-rotating arms. It a solar panel that powers the motor, and two AA rechargeable batteries for extended operation during dark periods.  The bird repeller is ideal for use on rooftops, AC units and roof vents to keep pest pigeons away.

Best Pigeon Control for Pest Pigeons

Pigeon-control-products-that-work

by Alex A. Kecskes

The ubiquitous pigeon has been man's friend and foe for centuries. Rising to nuisance level as they invaded our cities and towns, pest pigeons cause over one billion dollars annually in damage and cleanup costs.


It's not surprising. Pigeon poop alone can cause all sorts of damage. It can eat into wood and metal, ruin fine stonework, and seize up AC units. Worse yet, pigeon poop is teaming with bacteria, fungi and parasites, which is why it poses such a high health risk. After all, pigeon droppings have been known to carry any of 60 known diseases. And no less hazardous are the fleas, mites and ticks that infest pigeons. It's no wonder that pigeon control has become so important. Thankfully, there are a number of highly effective pigeon control methods on the market..

One can't talk about pigeon control without mentioning the various Bird Scare products currently available. These flash tape banners wave, flap and crackle in the breeze to frighten pigeons looking for a safe place to land and roost. The same holds true for the inflatable, Bird Scare Balloon. Imprinted with menacing looking predator eyes, these devices turn and flail in the breeze to frighten pest pigeons away.

Next up--Bird Wire Systems. These nifty pigeon control arrays incorporate a post and wire system to create a wobbly landing site for pigeons. The low-profile systems are ideal for keeping pigeons off ledges, parapet walls, rooflines, handrails and similar areas. Pigeons don't like to land on anything unstable and will quickly move on to more solid footing. Humane and economical, bird wire systems have been approved for use on Federal and State government structures. The best systems use nylon coated stainless steel wire, which holds up better in punishing weather.

Called the granddaddy of pigeon control--and bird control, for that matter--the Bird Spike has saved more signs, buildings street lights, and AC units than perhaps any other anti-pest bird device. Pigeons just won't land near the threatening looking spikes. You can get rigid U.V.-resistant unbreakable polycarbonate spikes, or opt for longer lasting slightly more expensive stainless steel spikes. The stainless steel spikes are available in a non-reflective metal finish and are often recommended by architects, contractors and government agencies. Installation is easy for they can be glued or nailed down to virtually any surface. They even come in a selection of colors so they'll blend in with your building's exterior décor. So successful are spikes as a pigeon control device that they have morphed in design to fit specific applications. For example, you can now get Girder Spikes, which will keep pigeons and larger pest birds from landing on girders or I-beams. They come with adjustable “C-clamps” to fit any size girder. There's also the Gutter Spike, ideal for preventing pigeons from landing and roosting in rain gutters.

Another pigeon control device that's shocking in its ability to deter pest pigeons is the Electric Track. Ideal for discouraging pigeons from settling on ledges, rooflines, parapet walls, signs, I-beams, and flat or curved surfaces, these electrified tracks impart a mild electric zap to a bird's foot. Electric tracks are easily mounted on any flat or curved surface. The best are low profile in design and virtually invisible to anyone looking up from ground level.

Somewhat entertaining to watch as birds try unsuccessfully to land on it, the Bird Slope has proven itself a worthy adversary to the determined pest pigeon. Essentially just a slippery, angled PVC panel, pigeons just slide off them faster than you can say pest pigeon. It doesn't take long for pigeons to decide, this is a no-landing zone and leave. Bird slopes are ideal for beams, ledges, eaves, and other L-shaped areas where pigeons like to nest and roost. The panels come in several colors. Opt for UV stabilized polycarbonate panels if you can, as they will last longer.


If you believe only bird barrier deterrents will suit your application, you might try Bird Netting as a means of pigeon control. While pest pigeons may be able to land on these, they won't be able to get through. Netting is ideal for sealing off rooftops, courtyards, patio covers, and other large areas, including groves and vineyards. The finest netting is ISO 1806 mesh test polyethylene fabric. For rugged outdoor use, opt for U.V. stabilized, flame resistant and rot and waterproof netting.

If the sounds of pest pigeons landing on your property annoy you, you can now fight back with sound. Known as Sonic Repeller, these pigeon control devices produce a variety of annoying distress and predator calls only pigeons can hear. Ideal for a wide range of outdoor applications, these systems are easy to set up and install.

Our next pigeon control solution is actually a gel--called Bird Gel. Humane and highly effective, this chemical skins over but never really dries. When pigeons land on it, they can't wait to leave. The icky, sticky surface is one thing most birds, including pigeons, can't stand. The gel is easily applied to any surface using a caulking gun.

Got Pigeon Control?

Pest-pigeons
by Alex A. Kecskes
Pigeons, pigeons and more pigeons. They're everywhere. Nesting and roosting and laying claim to our homes, businesses and parks. On occasion, we like to feed them. Which unfortunately just encourages them to gather in larger flocks. And that means a bigger mess and more long-term damage. Damage that costs America upwards of one billion dollars annually.

We've seen what pigeon poop can do. It can ruin wood and metal, crumble concrete and fancy stonework, even stop a big industrial sized air conditioner. And since pigeon poop is rich in bacteria, fungi and parasites, it poses a considerable health risk. Experts will tell you that pigeon droppings can carry and transmit any of 60 known diseases. Add to that the fleas, mites and ticks that bury themselves in pigeons and you've got one disease carrying bird on your hands. All the more reason for getting the best pigeon control available.

What to do? Cull and destroy our fine-feathered friends? No need. Not with today's more effective methods of pigeon control. And there are so many to choose from.

For starters, there's the inexpensive category of pigeon scare products available today. These include bright, colorful banners that rattle and wave in the breeze. Sometimes referred to as foil or flash tape, they are easily affixed to almost any object and will discourage pest pigeons from landing and nesting. The same holds true for another pigeon control device, the balloon. It not only whips about in the breeze but has large predator eyes to scare pigeons away.

Highly successful in keeping pigeons from landing and roosting are bird wire systems.

This method of pigeon control uses a post and wire system that provides an unstable landing area for pigeons. The low profile bird proof deterrent is ideal for keeping pigeons off ledges, parapet walls, rooflines, handrails and similar troublesome areas. Once pigeons try to land on the wobbly wire, they simply move on to find a better perch. Approved for use on Federal and State government structures, bird wire systems are humane, safe and economical. Better systems use nylon coated stainless steel wire to withstand harsh weather.

Just about everyone has seen our next category of pigeon control devices--the bird spike. These have proven so successful that you can now get them in a variety of styles and materials. There's the plastic spike made of rigid U.V.-resistant unbreakable polycarbonate. These can be glued or nailed down to virtually any surface and come in a variety of colors. Next is the steel spike made of durable stainless steel. It comes in a non-reflective metal finish and is often recommended by architects, contractors and government agencies. Then there are also girder spikes, great for keeping pigeons and larger pest birds from landing on girders or I-beams. These typically have adjustable “C-clamps” to fit any size girder. Last in the spikes family is the gutter spike, ideal for keeping large pest birds like seagulls, crows, and pigeons from sitting on or in gutters.

Next up is the bird slope. This clever pigeon control device is essentially just a slippery, angled PVC panel. Pigeons who try to land on these do quite a dance as their feet "squirrel cage" to try and get a footing. Frustrated after a few tries, pigeons move on to more stable surfaces. Ideal for beams, ledges, eaves, and other 90-degree areas where pigeons like to nest and roost, the panels come in several of colors to match a building's décor. The best panels are made of UV stabilized polycarbonate for lasting durability.

To keep pigeons from landing on ledges, rooflines, parapet walls, signs, I-beams, and flat or curved surfaces, there's the electric-track pigeon repeller. These electrified tracks discourage pigeons from coming back by imparting a mild "jolt". Ideal for almost any flat or curved surface, the low-profile electrified tracks are easy to install and almost invisible to anyone looking up from below.

As a physical barrier, nothing beats bird netting for pigeon control. Correctly installed, pigeons simply can't get through, give up and leave. Netting is widely used to keep pigeons away from rooftops, courtyards, patio covers, and other large areas. If you want the netting to last, opt for ISO 1806 mesh test polyethylene fabric. It's U.V. stabilized, flame resistant and rot and waterproof.

Bird gel is another pigeon control solution that's been proven effective over the years. The chemical goop skins over when it dries and leaves a sticky surface that birds can't stand. Best of all, it's non-toxic and harmless to birds.
Last but not least is the scarecrow, a motion-activated sprinkler that pulses out a water stream each time it senses a pigeon flying or walking near it. The water spray, the scarecrow's moving head and the sprinkler sound--all combine to convince birds to stay away. Ideal for keeping pest pigeons away from backyards, gardens, pools/spas and other areas you want to keep clean and bird free.

The Many Methods of Pigeon Control

Pigeon-control
by Alex A. Kecskes
Pigeons have been both friend and foe to mankind for centuries. They have inspired poets and saved lives in wartime.  But when they gather in great numbers in cities and towns, they can be most unwelcome. As a pest bird, they can also be most prolific. A single pair of pigeons can produce as many as 18 new pigeons every year--it only takes 19 days for a pigeon egg to hatch baby pigeons.
Then, there are the droppings. One pigeon can generate up to 25 pounds of droppings every year, droppings that attract parasitic insects and flies. Droppings that can spread over 60 transmittable diseases to people and animals. According researchers of the Albert Einstein College of Medicine in New York, pigeon droppings can expose children to Cryptococcus Neoforman fungus. This is airborne fungus grows in rotting pigeon roots, and is present in pigeon droppings. The first step in controlling pigeon droppings is more effective pigeon control.

Aside from disease, the highly acidic nature of pigeon droppings can destroy metal, paint and roofs. In fact, droppings and nests can present property owners with an ongoing repair bills to cover damages to gutters, shingles, AC units, skylights, and dish antennas.

Thankfully, there are a number of highly effective pigeon control products currently available. Most are designed to discourage pigeons from landing and roosting. Moreover, these products have been carefully designed to avoid harming birds, animals and people.

Bird Spikes 

They look like they might impale anything that comes near them, but blunted Pigeon Control Spikes are harmless to birds and people. What makes them so effective is that birds won't land near them, since they simply can't get their wings around them. Spikes come in rigid U.V.-resistant unbreakable polycarbonate, or longer lasting slightly more expensive stainless steel. Steel spikes are available in a non-reflective metal finish and architects, contractors and government agencies will often specify them. The ever-popular spikes are now available in different styles to meet specific pigeon control needs. Girder Spikes, for example, are ideal for keeping pigeons and larger pest birds from landing on girders or I-beams. They come with adjustable “C-clamps” to fit any size girder. Gutter Spikes, on the other hand, are ideal for deterring pigeons from rain gutters. In general, spikes are easily glued or nailed down to almost any surface.

Electric Tracks

These pigeon control devices use a harmless jolt of electricity to discourage pigeons from nesting. Electric Tracks are ideal for persuading pigeons from gathering on ledges, rooflines, parapet walls, signs, I-beams, and flat or curved surfaces. The electrified tracks are easy to install on most any flat or curved surface. Best are the low profile tracks, which are virtually invisible to anyone looking up from ground level.

Bird Slopes

These are simple, surprisingly effective PVC panels that present an angled, slippery surface to pigeons that try to land on them. Bird slopes are an ideal pigeon control solution for beams, ledges, eaves, and other L-shaped areas. The panels can be ordered in a variety of colors to blend in with your building's décor. UV stabilized polycarbonate panels are best as they stand up to tough weather. 

Pigeon Netting

Bird netting can be an effective pigeon control solution. Ideal for use on rooftops, courtyards, patio covers, and other large areas, netting presents a physical barrier that keeps pest birds out. Some of the best netting is made from ISO 1806 mesh test polyethylene fabric. U.V. stabilized, flame resistant and rot and waterproof netting is also available.

Sonic Pigeon Deterrents

Sonic Repellers generate sounds that annoy or alarm pigeons. These pigeon control systems emit a variety of bird predator sounds through a speaker system. To deter pigeons, these systems effectively recreate the sounds of Peregrine falcons defending their territory. The calls are repeated regularly--usually once every ten to fifteen minutes. Sonic systems are ideal for deterring pigeons from backyards, courtyards, gardens, pool areas, patios, gazebos, parks, golf courses, rooftops or other large open spaces.

Bird Gels 

As a humane pigeon control solution, Bird Gels can be quite effective. The sticky goo goes on easy with a standard caulking gun. In general, gels skin over but don't dry, leaving pest pigeons with an irritatingly tacky surface to plant their little footsies on. Of course, once they land, they can't wait to leave.

Pigeon Control…the Good, the Bad and the Ugly

by Alex A. Kecskes
There have been many ways and means to achieve pigeon control. Some effective, some not so effective, and others just plain nasty.
The most obvious and shortsighted is to simply shoot them. This is ill advised by most agriculture departments and pigeon control experts, since pigeons are most prolific in cities and well-populated areas, and firearms are outlawed by most municipalities. One tends next to turn to pigeon poisons, but these have often failed in the long run because the first birds to die are the weak and old, leaving more room for fertile birds to reproduce. Still another strategy that has met with mixed enthusiasm is to fine those who feed pigeons. As most people know, pigeons are scavengers and will find plenty of food without resorting to direct handouts from humans. At one point, New York City even proposed creating a "pigeon czar" to look into various methods of pigeon control.
Perhaps the most bizarre way of getting rid of the annoying "rock doves" came from one very frustrated individual who had had it with the pests defacing statues. The idea was to install a magnetic coil on the protuberances of every statue. The pigeons would then be fed grain containing Semtex (or C4 plastic explosive) along with a micro detonator. When birds landed on the statue, the detonator would be activated by the magnetic coil and boom, the hapless birds would be sent to Valhalla. The charge would be just powerful enough to "off" the bird yet small enough to prevent if from splattering apart. Needless to say, animal rights groups were not in love with the concept.
Fortunately, there are far more humane, safe and sane ways of pigeon control currently available.
Bird Wire Systems
Pretty simple when you think about it. Birds like to land on wires. They land on these wires and do the boogie trying to keep from falling off. After a few seconds, they leave. Bird Wire Systems with their post-and-spring-wire set-ups are anything but stable. String these pigeon control systems up wherever pigeons have been a nuisance--on the roofs, ledges, railings, signs, etc. The systems install easily and are often used on Federal and State government buildings. The best systems feature nylon coated stainless steel wire to last longer.
Bird Slopes
Sometimes called the invisible pigeon control deterrent, Bird Slopes look good and work great. These angled, slippery PVC panels make it virtually impossible for pigeons to land in all those 90-degree nooks and crannies of a building or structure. Birds slip and slide off these panels like teens at a waterpark. The panels even come in several colors to blend in with your building's aesthetics. U.V.-stabilized polycarbonate panels are best as they stand up and stay slick in punishing weather.
Bird Motels
They go in and you take them out--far out to the boondocks. That's the idea behind these catch-and-release Bird Motels. Now, if you've got a billion pigeons already occupying your property, this may not be the most effective pigeon control method to use. These motels are ideal for relocating just a few annoying pigeons. You can put these just about anywhere pigeons like to gather. The best motels feature an easy-access door and are constructed of galvanized wire so they won't rust or corrode. Consult a bird control expert to determine which motel is ideal for your specific application.
Pigeon Netting
This stuff is a widely used method of pigeon control, since it effectively and humanely denies a bird access to specific areas of a building or property. The best Bird Netting is made from ISO 1806 mesh test polyethylene fabric. To make sure your netting won't shred apart like confetti after a few seasons, opt for U.V.-stabilized, flame-resistant and rot and waterproof netting. Non-conductive netting is available for installations where electrical conductivity or EM interference may cause problems. Some manufacturers even offer pigeon netting in different colors--like white, stone and black.
Scare Devices
An economical way to discourage pigeons from landing on or near your property, Pigeon Scare Devices make birds nervous. And nervous birds don't hang around. Among the most popular scare devices are flash tape that crackles in the wind, banners that flap and snap in the breeze, and balloons covered with scary predator eyes that bob and weave.
The only thing to remember about these pigeon control devices is that pigeons are among the smartest birds on earth, which means you might consider swapping out the devices or the clever little suckers will simply ignore them.
Bird Spikes
The "Big Kahuna" of pigeon control devices   (or most any bird, for that matter), the Bird Spike keeps flying pests from landing on any surface. Yes, they look like a medieval torture device, but the blunted spikes are harmless to birds, pets and people. Depending on your need and budget, you can choose either rigid U.V.-resistant unbreakable polycarbonate spikes or the longer-lasting, slightly more expensive stainless steel spikes. Some manufacturers offer the spikes in a variety of colors--including white, tan, gray, black, brown, brick red and crystal clear. The spikes are easily glued or screwed to any surface.
To keep pigeons off girders or I-beams, there's the Girder Spike, which sometimes comes with adjustable “C-clamps” to fit many girder sizes. To keep pigeons clear off rain gutters, opt for the Gutter Spike.
Sonic Repellers
Like most birds, pigeons don't like to hear the sounds of natural predators--like peregrine falcons (a pigeon's dreaded enemy), or the cries of their fellow pigeons in distress. When they do, they leave in hurry. Sonic Repellers broadcast the sounds pigeons hate. And they do it with surprising efficiency. The sounds are repeated regularly--usually once every ten to fifteen minutes. The sounds are not annoying to humans, but pigeons hate them.
Bird Gels
No self–respecting bird likes feeling trapped, especially with every step they take once they've landed. Sticky Gels bug the heck out of pigeons--and most birds for that matter. Bird Gels are easy to apply to most surfaces using a standard caulking gun. The chemical skins over and stays sticky for up to six months before you need to reapply it.
