If your home is near a lake, reservoir, or even a large pond, and you have an attractive koi pond, you’ll want to protect it from large birds such as the crane or Great Blue Heron.
With its subtle blue-gray plumage, the heron often stands motionless as it scans for prey or wades belly deep with long, deliberate steps. And while they may move slowly, herons can strike with lightning speed to grab a fish. Equally threatening to koi are cranes. These large, gregarious birds can stand completely still for up to 20 minutes, which makes them seem nonthreatening to koi until the birds strike.
To protect your koi, add plenty of floating vegetation for your fish to hide under, as well as structures to dive below. Your pond should be three to four feet deep. Small ponds with shallow areas make fish easy prey. Herons will not dive, they spear their prey, so if your fish can stay deep and hide, they’ve got a chance to survive a heron attack.
In terms of bird proofing, there are many effective and humane bird deterrents you can use to protect your koi.
Repeller 360
A wind-powered device, the Repeller 360° features two "sails" with reflective predator eyes mounted at both ends of a 6-foot stainless steel arm. The arms spin continuously a full 360° to intimidate even the largest birds daring to approach your pond. The device is easily attached to any virtually any surface using a variety of available bases.
Garden Bird Netting
Light, easy to handle and virtually invisible, Garden Bird Netting is made of tough, UV-protected polypropylene. This bird netting is sold in two roll sizes: 14 x 100 feet and 14 x 200 feet and several meshes. The 3/4-inch mesh is ideal for large birds like heron. Simply drape it over your pond and attach it with clips at the base.
Scarecrows
Harmless but highly effective, Scarecrows will discourage even the most determined large bird to stay clear of your pond. A motion-activated sensor controls the Scarecrow, blasting any bird that dares to enter its radius of protection with water. Scarecrows connect easily to your standard garden hose and will protect a 1,200-square-foot area (or a 35-foot by 45-foot wide swath)--more than adequate for most ponds. The Scarecrow’s sensitivity and effective radius are easily adjusted to the size and shape of your pond.
Diverters & Balloons
Reflective Bird Diverters and Predator Eye Balloons are designed to intimidate heron and other large birds. Diverters are flat, tear-drop shaped with a large predator eye to intimidate herons and similar birds. For best bird deterrent effect, diverters should be hung in various lengths and spaced 2 to 3 feet apart. Predator Eye Balloons are beach-ball size deterrents that also sport a large predator eye. Made of a weather-resistant vinyl plastic, the balloons have a top eyelet for easy hanging above your pond.
Winter is here and it’s time to winterize your home. This is typically when you seal all the cracks between wood and stucco, wood window casings, etc. It’s also the time when you need to check your rain gutters and spouts, and when you check around chimney areas and vents. It’s also the time when you should be thinking about bird proofing your home. Bird, after all will be looking to settle in for the winter and if your home isn’t protected with bird deterrents, they’ll gravitate to your home and you know what that means: nests, feathers and bird droppings. Nests in your rain gutters, patio covers, gazebos and all those nooks and crannies in your home’s exterior.
The good news is, you can prevent birds from flocking around your home by implementing an effective and humane bird control strategy. Here are several bird deterrents that you should consider installing when winterizing your home:Sonic Bird DeterrentsYou can blast air horns and set off firecrackers to scare birds away. But they’ll come back as soon as you go backing the house. Sound Bird Deterrents have been proven effective because they emit distress and predator sounds that frighten birds. The best sonic deterrents will emit sounds that birds can hear (unlike ultrasonic deterrents which emit sounds birds can’t hear). If you had crows, starlings, swallows, gulls, woodpeckers, sparrows, grackles, cormorants last year, you might want to consider using the sonic system many have turned to: it emits distress and predator calls for as many as 22 types of birds. By the way, sonic bird deterrents only create sounds that resemble normal birdcalls, so they won’t annoy your neighbors and pets. Balloons and BannersEasy to install and quite effective in deterring birds from your home and backyard, Banners, Flash Tape and Balloons make pest birds feel too uncomfortable to stay. These deterrents rattle and reflect sunlight as they twist and flap in the breeze. Balloons have the added advantage of large, predator eyes that spook birds, making them think a large predator is eyeballing them. For best results, these visual bird deterrents should be moved around occasionally to keep the threat looking alive and real.Bird SpidersEasy to place on rooftops, patio covers and other elevated areas, Bird Spiders boast long spindly arms that prevent birds from landing. Spiders come in 2-, 4- and 8-foot diameter arm lengths to protect increasingly wider areas. A variety of mounting bases allow for easy positioning on most flat areas. Bird Slope™Angled, slippery PVC panels, Bird Slope deterrents are easy to install in all those 90-degree nooks and crannies where birds tend to nest. The panels come in a variety of colors to blend in with your home’s aesthetics. The best panels are made of UV-stabilized polycarbonate to last longer in tough outdoor weather.

Several years ago, thousands of birds swarmed into South Pasadena, a small enclave near St. Petersburg, Florida. The horde of mostly crows filled shopping centers, dumped on cars and SUVs, and filled the air with their incessant screeches, cackles and caws. One observer noted crows in clusters of as many as 500 with a total of about 6,000. Other local residents said the crows had destroyed fruit trees, and cluttered sidewalks, benches and power poles with their droppings. Had South Pasadena taken steps to bird proof its streets and buildings, it might have been able to discourage the avian onslaught. While most towns aren't normally invaded by birds reminiscent in an Alfred Hitchcok film, there are instances where birds seem to have taken over a park, building, boat dock or other facility. Although this may not strike fear in the hearts of most people, it can be quite a nuisance. For even hundreds of pest birds can create a huge mess and destroy property. An outdoor eatery, for example, could lose considerable business were it invaded by pest pigeons pooping on tables and chairs. Mothers would be loath to allow their children to play in a park covered with large black crows. Vintners and growers have lost thousands of dollars worth of grapes and other crops, no thanks to bird swarms. And many a building owner has spent hefty sums sandblasting bird poop from building facades. All this points to the need to bird proof an area or building. Fortunately, there are many humane and effective ways deter pest birds.They Can't Land on Bird Slopes
Bird Slopes prevent pest birds from landing on many structures. The slippery PVC panels fit just about anywhere--on eaves, ledges, beams and other similar niches--and they just don't allow pest birds to get a solid footing. After several tries, birds give up and head for better landing areas. The angled bird proof panels are easy to install on almost any surface and will discourage a wide range of pest birds. Bird Gel Works Well Birds get the message real quick with this bird proof goop. Bird Gel presents pest birds with an icky, sticky landing zone that they can't stand. The gel will discourage all manner of pest birds. It's easy to apply on virtually any surface and is ideal for use on conduit, pipes, ledges, I-beams and parapet walls. The goop hardens after about six months, so you'll need to reapply it for best results.Pest Birds Spurn SpikesHumane and highly effective, Bird Spikes have gained widespread popularity in cities and towns across the country. While they may look like they could impale anything that comes near them, the blunted spikes are actually quite harmless to birds, pets and people. Spikes rely on a simple principle: birds simply can't navigate their wings and feet around them, so they move on to better landing zones. Bird spikes come in long-lasting stainless steel or rigid unbreakable polycarbonate. Installation is fast and easy on any flat surface or ledge. Some spikes come in two-foot long strips for easier installation. Spikes are an ideal way to bird proof most structures and the best spikes are virtually maintenance free.To address varying bird problems, you can get a Mega Spike, which has long 7-inch spikes--ideal for most seagulls, cormorants, turkey vultures, raptors and other large birds. Mega spikes are usually made of marine-grade stainless steel to endure harsh outdoor weather. If you can, opt for crush proof spikes with a non-reflective metal finish. And choose spikes with a U.V.-protected polycarbonate base that you can angle to fit around curved surfaces. Finally, there's the Gutter Spike. It's designed to keep large pest birds like seagulls, crows, and pigeons from nesting in gutters. Look for gutter bird spikes that have adjustable clamps at the base for easy installation to the lip of a gutter. Bird Spiders For Stubborn Pest BirdsResembling a giant Spider, Bird Spiders do a nice job of discouraging pest birds to stay away from restaurant tables, canvas boat covers, awnings, patios and other flat surfaces. The spider's spindly arms wave and flagellate in the breeze to bird proof an area. Bird spiders come in several arm lengths to scare away a wide variety of bird species.Deter them with Foggers and Misters Pest birds get all misty eyed after flying through an area protected by Bird Foggers and Misters. These systems effectively bird proof an area by releasing a fine mist of food-grade methyl anthranilate. This grape extract is harmless to birds and humans, yet pest birds hate the stuff. Simple foggers/misters basically consist of a sprayer and a canister of chemicals. More sophisticated systems use timers and multiple nozzles that allow you to direct the mist to specific sites and varying times and durations.Bird Proof with Better Net ResultsBird Netting is an ideal way to bird proof groves, vineyards, enclosed courtyards, patios and other large areas. The nets come in various mesh sizes to keep out pigeons, sparrows, starlings and seagulls. For lasting durability, choose bird netting that has been U.V. stabilized, and is rot- and water-proof. Bird Scare DevicesNo bird likes to feel threatened. And Bird Scare deterrents are quite effective as a bird proof solution. These are the reflective foils, shiny tape banners and balloons you see around buildings, parks, boat docks and other outdoor areas. Some balloons have a giant predator eye in the center to convince birds a huge predator is about to attack them. The basic principle here is to create an “Optical Distraction Zone” to scare pest birds away. Balloons can also be filled partially with water to skim the surface of swimming pools, spas and Koi ponds to frighten pest birds away.

Bird Scare deterrents have a long and successful history as effective bird proofing devices. These simple reflective foils, shiny tape banners and balloons work because they create a zone of optical distraction that birds just don't like to be around. Some produce a snapping noise in the breeze that adds to the distraction factor. One note about bird scare deterrents: They need to be moved around and replaced every so often or pest birds will get used to them.

While most of us don't have to worry about 9-pound birds knocking us off our bikes, smaller pest birds can knock us for a loop when it comes to property damage. Thousands of homeowners, boat owners, facilities managers and municipalities have suffered the ravages of pest birds. The nests, the droppings and the destruction and diseases they carry cost Americans millions annually. Many people have decided to fight back by bird proofing their property.
Modern Bird Proofing Methods
Birds don't like things that bob and weave in the breeze. That's the theory behind Bird Scare deterrents. These include reflective foils, shiny tape banners and balloons. Some balloons feature a giant eye, which adds to the fright factor. By creating an “Optical Distraction Zone,” these simple devices shoo birds away. Some of these deterrents combine a visual distraction with a crackling sound. Balloons can also be used in swimming pools and other water areas to float on the surface and frighten pest birds away.
