Let’s face it, in some large areas-”be they indoors or out-”it’s pretty tough to deter pest birds. This is where bird misting systems come in. The misters are ideal for use in large industrial or commercial garages, factories, airline hangars, courtyards, landfills, parking lots, or similar open spaces. Bird Misting Systems can be effectively used to deter pest birds from loitering dangerously near aircraft flight paths. Following the recent crash landing of a US Airways Airbus in the Hudson River after bird strikes apparently disabled both engines, misting systems have caught the interest of airport managers and flight safety organizations throughout the country.
The good thing about these bird hazing systems is that they are both humane and effective. They work by releasing an ultra fine mist into the air that pest birds can’t see and just don’t like. The mist is usually a chemical called methyl anthranilate, a grape extract that naturally occurs in concord grapes. Recognized by the FDA as a safe substance, methyl anthranilate is a food-grade material, often used to flavor grape soda and candies. The extract has been widely used for decades to safely deter a wide variety of pest birds including, sparrows, pigeons, starlings, crows, blackbirds and geese. Yet it’s safe for people, pets, plants and birds. Methyl anthranilate is a chemical substance that irritates the trigeminal nerve and mucous membranes of birds when it enters their eyes, nose or mouth. A flying bird will inhale the repellent up to 30 times faster than a bird at rest. The mist affects larger birds first. Smaller birds like sparrows will usually require longer periods of exposure. Many misting systems have a central console to which you can attach a number of satellite misting -œdrop- units. In some systems, the control console can be placed as far away as one mile from the drop units. In better systems, each of these drop units can be controlled individually, and each unit can cover thousands of square feet. The central console will typically keep track of liquid levels and let you know when to refill the units. If you opt for a programmable misting system, be sure to time the misting units to spray when pest birds are most active in the area you want to protect. In general, you will get best deterrent results if you set your spraying units to mist in the morning hours and in the evenings -typically dawn and dusk. And don’t forget to consider the effects of prevailing winds to make sure the mist is being carried in the correct direction. Some mist systems will work in the rain, but will be ineffective as a deterrent. And misting units will not work below 32 degrees Fahrenheit because the methyl anthranilate will freeze. Advanced misting systems will allow you to program the drops for a set time of day, or to go off throughout the day and or night. You can also control how long the mist sprays. The cycle time of each drop should be based on the type of facility you want to protect. The specific guidelines for use in warehouses, garages, loading docks, food processing plants, golf courses will vary depending on bird type and level of bird activity. Better systems will have individually adjustable nozzles on each unit to make ensure you direct the deterrent chemical exactly where you want it to go. Up close, the mist looks like a fine vapor with its visibility increasing the farther the mist travels from the unit. The better systems will not leave a residue behind. For those concerned about chemical odors, methyl anthranilate, will only have a grape odor.
