How to Keep Pest Birds Off Commercial Buildings

photo bird-control-buildings_zps8a4290d6jpg



Pest birds are always looking for a place to roost and nest on commercial property. And once they've settled on a building or warehouse, they tend to gather in greater numbers on rooftops, parapet walls, windowsills and other elevated ledges.

Without effective bird control measures to deter them, pest birds can deface and damage these areas fairly quickly. Bird droppings are not just unsightly. The acid in bird droppings can corrode metal and eventually erode stone. Bird droppings can jam up windows, doors, rooftop ventilators and skylights. This waste can also render moveable security cameras inoperative, “locking up” gimbal mechanisms. Droppings can damage expensive AC units by seizing up fans. Bird nests and droppings can even clog rain gutters and down pipes, causing rooftops to overflow with water. Some roof sections have actually collapsed due to bird damage.

Bird droppings are also unhealthy. They can carry any of 60 known diseases—like salmonellosis. This makes pest birds particularly hazardous in areas where food is stored, processed or served. Finally, bird droppings on walkways and entryways to a commercial building can create serious slip-and-fall hazards. Wet bird poop can be as slippery as a banana peel.

Failing to implement an effective bird deterrent strategy can saddle a commercial property owner with expensive cleanups, repairs and even legal liabilities. Fortunately, there’s a bird deterrent that gets rid of bird pests humanely, simply by denying them a place to land—it’s called Bird Slope.

Pest Birds Can’t Get a Grip

Bird-B-Gone’s Bird Slope is ideal for use on open ledges that meet at a 90-degree angle. Pest birds simply slide off these angled, slippery PVC panels whenever they try to land. The sloped panels install easily on eaves, ledges, beams and similar areas frequented by birds. And they are equally effective against all types of birds.

Up to 10 inches of Bird Deterrence

Bird Slope comes in 4-foot long sections and is sold 48 feet per box. The panels are easily screwed, glued or nailed to virtually any flat surface. A handy "snap on" extender makes it easy to adapt to ledges as wide as 10 inches. (The basic bird slope, without an extender can protect a 6-inch wide ledge.) You can also get mounting clips to install the panels vertically on the sides of buildings. Some Bird Slopes even come with “end caps” to prevent birds from getting behind the panels.

Aesthetic Solution to Bird Pest Problems

To blend in with its surroundings, Bird Slope is now available in two colors--stone and grey. Each panel is made of UV-protected PVC material to make it more resistant to sun and harsh weather. If you're installing Bird Slope next to electrical wiring, the panels are non-conductive for extra safety. A glue trough on underside of each panel makes for easy installation using standard outdoor polyurethane adhesive.




How To Get Rid of Birds Without Injuring Them

Get Rid of Birds photo get-rid-of-birds-from-your-homepng

A survey of municipalities across the country revealed that pigeons were the most widespread nuisance. After that, the most bothersome birds were blackbirds, starlings, house sparrows, crows and ravens. Strategies on how to humanely get rid of birds can occupy many a property owner.

Not surprisingly, the biggest problem caused by the number one nuisance bird (pigeons) is the volume of droppings they create. These deposits are not only smelly, but slippery, unsightly and a health hazard, carrying diseases like salmonellosis, ornithosis, cryptococcus, and histoplasmosis. Equally troublesome is the acidic composition of their droppings, which erodes metal and even stonework. To get rid of pigeons calls for some professional solutions that go beyond water hoses and firecrackers.

Grackles, blackbirds and starlings often invade cities in vast migratory and winter flocks. Seeking warmth and shelter, they form noisy, smelly roosts on city buildings and trees. The roosts often serve as breeding grounds for histoplasmosis. What’s more, bird droppings can destroy the vegetation under the roosts. Grackles, in particular, can quickly ruin backyard fruit crops. House sparrows can pollute patios, swimming pools, and the air entering outside air conditioners, allowing ectoparasites to enter homes and offices. To get rid of small birds like these without injuring them can be a challenge.

If you’ve been inundated by pest birds, consider implementing some humane, professionally recommended pest bird deterrents, including:

Site Specific Scarecrows 

Highly effective in getting rid of birds from specific areas, the Scarecrow is a motion-activated sprinkler that shoots a harmless but persuasive blast of water at any bird or birds. Scarecrows connect to any standard garden hose and will guard a 1,200-square-foot area (or a 35-foot by 45-foot wide swath). A Scarecrow’s motion-activated sensitivity and water spray radius can be easily adjusted to fit the application.

No-Perch, No Roost Bird Spikes

Designed to prevent larger birds like pigeons and crows from landing on roofs, patio covers and other elevated areas, Bird Spikes are harmless to birds, people and pets. Available in rigid unbreakable polycarbonate (plastic) or durable stainless steel, bird spikes are easy to install. They are ideal for getting rid of birds on rooftop AC units, skylights, and solar panels.

Distract and Deter with Balloons  and Diverters

Used together with the two deterrents listed above, Visual Bird Deterrents can be placed in any elevated, high visibility area to get rid of birds. Choose Reflective Bird Diverters or Predator Eye Balloons. Diverters consist of tear-drop shaped panels covered with a big predator eye to intimidate birds. You hang these in various lengths and space them 2 to 3 feet apart. Predator Eye Balloons resemble beach-balls and are covered with large predator eyes. The best visual deterrents will be made of weather-resistant vinyl plastic. For best results, it’s best to alternate the location of these deterrents since most birds are smart and will eventually get used to them as non-threatening.


The Top 5 Tactics to Get Rid of Birds

photo get-rid-of-birds-from-roofs.jpg

There are all sorts of ways to get rid of pest birds. Some are lethal and not recommended for most situations; others are simply ineffective. Fortunately, bird control experts have come up with some pretty ingenious ways to keep birds from ruining your property and frazzling your nerves. A sampling of the top 5:

Bird Spikes

The granddaddy of pest bird deterrents, Bird Spikes will get rid of larger birds—like pigeons, crows and gulls—from your roof, patio cover and other elevated areas of your property. Bird Spikes won’t harm birds or pets. They simply won’t allow birds to land or perch. The spiked strips come in rigid unbreakable polycarbonate (plastic) or durable stainless steel. Each two-foot long strip can be nailed, glued or screwed to most surfaces. There’s also the Mega Spike, which has large 7-inch spikes for keeping vultures from perching. And Gutter Spikes if you have a problem with birds nesting in your rain gutters.

Bird Slope

Blending in architecturally with your home or business, Bird Slope consists of slippery PVC panels that prevent birds from getting a solid footing under eaves and other elevated 90-degree nooks. Birds may be stubborn critters, but they soon give up after loosing their grip on these panels. The best bird slope panels are UV protected and sun- and weather-resistant to remain attractive and effective for years. Bird Slope is an effective way to get rid of many different types of birds—including swallows, starlings, pigeons, crows and more.

Garden Bird Netting

Working on the principle of denying access, Garden Bird Netting is lightweight and easy to handle. It comes in 14 x 100-foot and 14 x 200-foot rolls and can be cut to the size needed for various applications. Choose the mesh size that gets rid of the birds that cause you grief--1/4", 1/2" or 3/4". Bird netting clips are available to keep the netting conveniently in place. Look for netting made of durable, UV-protected polypropylene. It will last longer.

Copper Stuf-Fit Mesh

Perfect for keeping smaller birds out of all those little crevices, holes and nooks, Copper Stuf-Fit mesh is easily “formed” into the shape needed to get the job done. The mesh comes in 20-foot and 100-foot roles. It’s also rust-proof and stain proof (steel wool will rust, run and stain your property). Copper Stuf-Fit even keeps birds from working their way under roofing tiles, retractable awnings, and where pipes enter your siding or foundation.

BeakGuard Woodpecker Deterrent

Ideal for getting rid of woodpeckers, BeakGuard is easily applied to latex-painted surfaces, wood, fiber-cement, stucco, aluminum or vinyl. The specially designed finish warns woodpeckers that the surface is to be avoided. BeakGuard is harmless to woodpeckers or other birds. It leaves a vapor permeable, flexible membrane that is durable, color fast and resists dirt pick up. BeakGuard goes like paint—with a brush, roller, paint pad or spray equipment.

How to Humanely Get Rid of Pest Birds

The pigeons are coming. So are blackbirds, starlings, house sparrows and crows. They’ll be invading your property en masse as bird season approaches. Will you be ready to get rid of birds when they arrive?

Prepare now or risk having your home invaded by birds.  Your cars will be spotted with bird droppings. So will your windowsills and patio furniture. Larger pest birds will tear apart your roofing shingles, causing leaks.  Smaller birds will build nests in your rain gutters, causing water to back up under your roofing tiles and, once again, you’ll have a leaking roof. Birds large and small will contaminate your pool and spa, so you’ll have to drain and clean them—not a pleasant thought.

Unless you have bird control devices in place, it will become increasingly difficult to get rid of pest birds. The temptation will be to use lethal means—like poisons or pellet guns—or stop-gap measures like water hoses and firecrackers.  Eventually, under pressure from your kids and neighbors, you’ll agree to more humane bird deterrents. Devices that actually work. Here’s what the pros recommend:

Scarecrows  for Pools, Spas and Gardens

Highly recommended for deterring all types of birds from areas where the presence of water is tolerated, Scarecrows are motion-activated sprinklers that spray a harmless but persuasive blast of water at any bird that wonders into its zone of protection. Scarecrows hook up to any standard garden hose and will guard a 1,200-square-foot area (or a 35-foot by 45-foot wide shape). The Scarecrow’s sensitivity and coverage area can be easily adjusted to suit the needs of your garden, pool or spa.

Bird Spikes for Roofs & Patio Covers

Birds usually seek a high perch from which to observe before they dive bomb your pool, spa, patio tables or car.  Bird Spikes deny them that perch. Ideal for larger birds like pigeons and crows, Bird Spikes are harmless to birds, people and pets. They have earned the approval of the U.S. Humane Society and PICAS (Pigeon Control Advisory Service). The spiked strips come in rigid unbreakable polycarbonate (plastic) or durable stainless steel. Gutter spikes are also available to keep birds out of your rain gutters. All are easy to install using glue, screws, clips or tied downs.

Balloons  and Diverters  for Trees

Known as Visual Bird Deterrents, Reflective Bird Diverters and Predator Eye Balloons bob and wave in the breeze to get rid of birds through intimidation. Diverters are tear-drop shaped panels covered with a big predator eye. They are hung in various lengths and spaced 2 to 3 feet apart. Predator Eye Balloons are covered with huge predator eyes. Look for visual deterrents made of weather-resistant vinyl plastic. For best results, it’s best to move these bird deterrents around often, or most birds will eventually get used to them as a non-live object to be ignored.


 

How to Keep Birds Away from Eaves, Canopies and Awnings

home-eave

As a homeowner, you know the problems pest birds can create when they’re allowed to roost and nest in eaves, canopies, awnings and other covered areas around your home. The beams of your patio cover, gazebo  and other elevated backyard structures offer an ideal sanctuary for birds. These areas protect them from weather and predators. Unfortunately, when  birds gather there, they create quite a mess down below—on your patio table, chairs, BBQ, walkways, spa, pool and thru-window serving bars. Kids toys can also become covered with disease carrying bird droppings.

Fortunately, there are a number of effective and humane bird control products you can use to keep birds away from your eaves, canopies and awnings:

Garden Bird Netting

A lightweight, easy to handle mesh, Garden Bird Netting physically denies pest birds access to specific areas of your home. It comes in 14 x 100-foot and 14 x 200-foot rolls and can easily be cut down to the size you need. It’s also available in three different "mesh" sizes: 1/4", 1/2" and 3/4" mesh. The netting installs easily under eaves and other areas, and bird netting clips are available to further speed installation. The best garden bird netting is made from a durable, UV-protected polypropylene. It’s strong, lightweight, designed for temporary use and practically invisible.
 
Bird Slope

Another bird control product that effectively denies birds access to your eaves is Bird Slope. The angled PVC panels won’t allow birds to gain a solid footing on its slippery surface. After a few tries of “squirrel-caging” on the panel, birds just give up and move on. Bird slope panels come in different colors to blend in with your home’s exterior. The panels are easy to install using glue, nails or screws and they're basically maintenance free.

Copper Stuf-Fit Mesh

If your home has a number of small holes and crevices under the eaves and other architecture, Copper Stuf-Fit mesh will keep birds out. It works great for all those tight spaces too small for regular netting or other bird control products. The mesh comes in 20-foot and 100-foot roles and can be “shaped” to conform to the area needed to keep birds out. Stuf-Fit mesh holds its shape in small, narrow areas so birds can’t “work” their way around it. The mesh can even keep birds from getting under your roofing tiles, retractable awnings, and junctions where pipes enter your siding or foundation.

No Nasty Nest

Simple but effective, No Nasty Nest uses hanging "twine" to block birds from potential  nesting sites. Confronted with working through a gauntlet of twine strips, birds will simply move on to a better nesting spot. If you had swallow mud nests under the eaves and sides of your home last year, No Nasty Nest makes a great bird deterrent. Each strip of No Nasty Nest features a self-adhering back for quick application on eaves, gables, entryways and other areas.

How to Keep Birds Away from Garages and Sheds

Pigeon Control, Get rid of pigeons with pigeon control products.

If your home has a separate garage or shed, you probably have pest birds roosting and nesting either inside or under the  eaves.  Birds love to perch on the rooftops and exposed beams of these structures.  And unless you deter them with some bird control device,  birds will continue to gather in greater numbers in and around these structures. Eventually, birds will even start to nest and roost under the eaves of your home.

The longer you wait to implement some effective bird control measures, the more brazen the birds will become.  They’ll start to gather in your back yard and leave droppings all over your pool, spa, patio, and BBQ.  Keep in mind that birds can carry any of 60 known diseases. If you have children or pets, you’ll be cleaning up the bird droppings on a daily basis.

The good news is that there are a number of humane and effective bird deterrents that you can use. Here are a few that you should look into:

Garden Bird Netting

Lightweight and easy to handle, Garden Mesh Netting will block birds from specific nesting sites around your shed or garage.   It comes in 14 x 100-foot and 14 x 200-foot rolls, but you can easily cut it down to the size. It’s also available in three different "mesh" sizes--1/4" mesh, 1/2" mesh and 3/4" mesh. It’s easy to install under eaves and other areas, especially if you use the bird netting clips that are recommended. The netting is made from a durable, UV-protected polypropylene. It’s strong, lightweight and virtually invisible.

Bird Slope

Scientifically designed to keep pest birds away from eaves and similar nooks and crannies, Bird Slope are slippery PVC panels that mount under eaves  to prevent birds from gaining a foothold. They scramble and “squirrel-cage” with their little toes and finally give up, moving on to other more hospitable areas. The best bird slope panels are UV protected and sun- and weather-resistant to last longer. Bird slope is ideal for deterring a wide range of birds—including swallows, starlings, pigeons and seagulls. The panels blend in with most architectural styles and they’re now available in two colors--stone and grey.

Copper Stuf-Fit Mesh

Ideal for keeping pest birds out of small holes and crevices, Copper Stuf-Fit mesh creates a physical barrier that blocks out birds. It’s ideal for use in openings and tight spaces too small for regular netting or other products. The mesh comes in 20-foot and 100-foot roles and can be “formed” into the shape of the area needed to deny birds access. The wire mesh will hold its shape in tight areas to prevent birds from “working” their way around it. It can also be used to block birds from getting under roofing tiles, retractable awnings, and where pipes enter siding or foundations.

No Nasty Nest

Ideal for use in blocking swallows, No Nasty Nest consists of hanging "twine" that denies birds access to nesting sites. Faced with wading through the twine strips, birds will simply move on to a better spot to nest. If you have swallow mud nests under the eaves and sides of your garage, shed or home, you’ll want to get this bird deterrent. Each strip of No Nasty Nest has a self-adhering back for fast application on eaves, gables, entryways and other areas.

How to Keep Gulls Away from Your Home

Bird Proof your Roof, Get rid of birds from your roof with bird proof products.

If your home has been besieged by gulls, you know what a nuisance they can be. These scavengers will eat just about anything that’s on your patio, boat dock or backyard. That includes fish, insects, mollusks, worms, mice, young birds, bird eggs, and berries. When gulls feast and gather, they'll leave an awful mess. They can cover your backyard and patio area with smelly, disease carrying droppings and rotting fish. If they use your rooftop to tear apart their prey, they can dislodge and damage roofing tiles and other rooftop structures.

Like most birds, it’s not just one type of gull you have to worry about. There are over 45 species of gulls. Your typical gull is a medium to large bird with a mostly white body and grey or black markings on the wings and tail. Their stout, orange bills and webbed feet make them easily recognizable. While gulls are often found near large bodies of water like bays, inlets and lakes (as well as the ocean), they have been known to venture inland for food. So don’t be surprised to see them on the roof of your home or patio if your home is miles inland. 
 
To keep gulls away from your home, you should first remove any open food source such as open trashcans or pet food. After that, you’ll need some effective bird control measures to keep them away. Here are three bird deterrents the pros use:

Bird Spikes for Gulls

Gulls regularly choose the roof of a home or structure to roost on. The peak of a roof is an especially desired area as it provides a nice look out point for food and predators. Bird Spikes are a humane product used to keep gulls off roof lines, parapet walls, pilings and other areas. Bird Spikes simply create an uneven surface that gulls know they cant land on. Spikes that are pre-assembled, such as the Stainless or Plastic versions are easiest to install.

Bird Spiders

Bird Spiders have spindly arms that whip about in the wind. Gulls see these and will simply move on to a friendlier landing perch. Bird Spiders are easy to set up on decks, posts, atop light fixtures, rooftops, fixed umbrellas and awnings. These bird deterrents are available in 2-, 4-, 6- and 8-foot arm lengths to create larger and larger areas of bird deterrence. Look for bird spiders that feature a glue-on base, which can be attached to most surfaces.

Sonic Gull Control

No gull likes to hear his fellow gulls being attacked. Or the sound of Peregrine falcons screeching in for the kill. Bird Sonic Deterrents exploit these fears and drive gulls away. These devices broadcast prerecorded distress and predator calls that resemble normal bird sounds to humans. One popular device features a built-in speaker that covers up to one acre. The unit can be programmed to turn on or off at night, and you can even adjust the volume.

How to Get Rid of Pest Birds Once and for All

by Alex A. Kecskes

Are you tired of all those bird droppings around your backyard? Wish you could get rid of those birds attacking your fruit trees? Or how about those birds pooping on your boat or RV in your side yard? 

Seems every few months, you have to spend hours scraping bird droppings off your boat cover or RV (not to mention, the nests and bird debris all over your RV’s AC unit). Then there’s cleaning your driveway and scrubbing bird droppings off your fence and gate. All that time wasted. If you’re lucky, you removed the bird droppings in time—before they permanently damaged anything. 

The question you have to ask yourself is, how long are you going to put up with the nuisance of pest birds? You tried hosing the birds away—but they just came back. You tried using your pellet gun, but that just sent pellets into your neighbor’s yard and caused arguments.

Speaking of your neighbor, you noticed that he doesn’t have any pest birds around his yard or home. And you wonder , why is that? Maybe he did something to keep his home and yard pest bird free.  Maybe he consulted a bird control expert who advised him on how to get rid of pest birds.

Here’s what the bird control expert might have advised your neighbor (and you) to do to get rid of those annoying pest birds:

Hang up Some Visual Bird Deterrents

The experts refer to these as Bird Scare Deterrents and they'll uses phrases like “create a visual distraction zone” or “bird intimidation.” But all you need to know is that they’re inexpensive, effective and easy to install. The best of breed in this category are the Scare Eye Diverters and Bird Scare Balloons. They feature a big, scary “mock” predator eyeball that birds think is a huge predator sizing them up for a meal.  You can hang these on the back of your boat or RV, in trees, patios, fences or any highly elevated area around your home. These balloons and diverters bob and weave in the breeze, which makes them look alive. Of course, birds may eventually get used to them,which is why you need to move them around from time to time.

Set Up a Sonic Bird Deterrent

Pest birds are ever vigilant when it comes to imminent threats. They detect sounds faster than humans. Sonic Bird Deterrents exploit these characteristics by broadcasting the sounds of distress and predator calls. Birds hear their compadres being attacked and they beat wing away from your home and backyard. The sounds resemble normal bird squawks to humans, so they won’t bother you, your neighbor or pets. One popular sonic bird deterrent unit covers up to one acre, comes with a volume control, and you can even pre-set it to turn on or off at night.

Keeping Your Patio & Patio Covers Pest Bird Free

Photobucket

by Alex A. Kecskes

Birds like to perch on patio covers to get the “lay of the land” of your patio. They’ll loiter there and wait to see what you’re BBQing or serving for your outdoor breakfast, lunch or dinner. And the minute the opportunity presents itself, they’ll dive bomb your patio table for any uncovered, unguarded food. The worst part is, they’ll also leave bird droppings on your table and (heaven forbid) on any uncovered food.  So needless to say, you want to keep pest birds away from your patio covers and patio area. One way to do that is with effective bird deterrents. Here are just a few of the most popular bird control measures:

Creating a Visual Distraction Zone

Birds, in general, are easily shooed away—either by noise or a moving object that makes them too nervous to stay. Bird scare deterrents do just that. They include Flash Tape and Reflective Banners, which reflect sunlight and crackle in the breeze. Equally effective are Scare Eye Diverters, which are large teardrop shaped plastic panels with a large “mock” predator eye and shiny reflective surface.  Many homeowners also like to use Bird Scare Balloons, which are beach-ball size deterrents covered with large predator eyes. These visual deterrents are all fairly economical and easy to attach to various areas of your balcony, patio, or gazebo. The one thing to keep in mind is that birds are not dummies, so you’ll need to move these deterrents around from time to time to prevent birds from getting used to them.

A Sound Investment in Bird Control

They’re called Sonic Bird Deterrents and they’re easily set up on your patio cover or under the roof of your gazebo. They emit bird distress and predator calls that sound just like normal bird sounds to the average human. But the sounds are threatening to birds, and they would much rather leave than stick around. One popular bird sonic system can emit distress and predator calls for 22 different species of birds. It comes with a built-in speaker and covers up to one acre. With a system like this, your patio will be protected from pigeons, crows, starlings, swallows, gulls, woodpeckers, sparrows, grackles, cormorants and many other types of birds. The system can be programmed to turn on or off at night and your can adjust the volume of sounds emitted.

Hawk Decoys, the Decorative Deterrent

Red tailed hawks are the natural predators of most pest birds. And unlike owls that hunt at night (when most birds are sleeping), Hawks hunt during the day. The key thing to remember about hawk decoys is they have to be realistic and of high quality. They should be fabricated of heavy-duty plastic to maintain their appearance after several seasons of harsh weather. A couple of hawk decoys, strategically placed around your patio can be an effective pest bird deterrent. Just remember to move them around and reposition them from time to time for best effect.

Two Sure Fire Ways to Keep Pest Birds Off Your Roof


by Alex A. Kecskes

For most people, their home is their biggest investment. And the part of the home that takes the biggest beating is the roof. It has to fend off attacks from sleet, snow, rain, wind and pest birds. How can pest birds damage your roof?  Without adequate bird deterrents, it’s surprising just how much trouble birds can cause.

For starters, birds will often take insects and other small prey to the safety of your roof to peck and claw their catch apart. This can damage roof tiles (especially, crown tiles made of wood or asphalt shingle). Replacing roofing tiles can run into big money. Birds have even been known to build their nests under roofing tiles. This kind of activity can dislodge the tiles, which can cause leaks.

Birds will also build their nests in your rain gutters. When their eggs hatch, the birds will simply leave the empty nests to clog up your gutters. Repeated rains will cause water to back up and seep under roofing tiles to eventually cause leaks. Once again, you’re stuck with expensive roof repairs. If you have attic ventilation turbines, skylights, solar panels, or solar water heaters, pest birds can damage them. If your chimney lacks a screen, pest birds can get trapped inside, block airflow, and create a potentially dangerous situation where deadly carbon monoxide gas enters your home. Bird proofing can save you from these and other problems.

Finally, it’s worth noting that bird droppings are highly acidic. Over time, accumulated droppings can degrade a roof, causing it to leak and possibly even collapse. Proper bird proofing can deter pest birds and save your roof. Here are two proven bird control measures that will keep your home pest bird free:

Sonic Deterrents—the Sound Solution

Birds like the safety and security of your roof—unless they sense danger. Sonic Bird deterrents generate distress and predator calls that make birds way too jumpy to hang around your home. One commercially available system can generate these calls for 22 different types of birds. The calls, repeated every 10 minutes, sound just like natural birdcalls to the human ear. Even pets can’t tell the difference, but birds sure can. The best sonic deterrents can be programmed to turn on or off at night and include a built-in speaker that covers up to an acre.

Bird Spikes Won’t Let ‘Em Land

You’ve seen these just about everywhere. Some are made of marine-grade stainless steel and feature a U.V.-protected polycarbonate base. You can also get durable polycarbonate bird spikes that come in a variety of colors--like white, tan, gray, black, brown, brick red and crystal clear--so they’re less noticeable and blend in with your home’s exterior colors. To keep pest birds from building nests in your rain gutters, Gutter Bird Spikes will do the trick.
