Avian Control (active ingredient: methyl anthranilate or MA) offers an efficient tool for the management of nuisance birds without harming birds or other animals. Generally used in flavors and fragrances, Methyl Anthranilate (MA) is a naturally occurring biochemical present in concord grapes and many blossoms with reduced risk to the environment. Additionally, this unique compound serves as the active ingredient in bird repellents. The ability of MA to repel birds has been known since the early 1960’s.
Dimethyl and methyl anthranilate have been used as food additives for a number of years. The orange-flower odor and slightly bitter, pungent taste have added their characteristic qualities to alcoholic and nonalcoholic beverages, ice creams, candy, baked goods, gelatins, drugs and chewing gum (Furia and Bellanca 1989) as well as perfumes (Bedoukian 1951). Research has also found that certain anthranilitic acid derivatives may be effective as bird repellents (Kare 1961).¹
Bird response of the vaporized fluid in the Bird Buffer is using less than 5 ppm. Higher concentrations are not necessary if the automated cycle constantly introduces new and fresh vapor-particles in the air where the birds fly.
MA is listed by the Unites States Food and Drug Administration (US FDA) as a flavoring compound in 21 Code of Federal Regulations (CFR) 182.60. The compound is classified as Generally Recognized As Safe (GRAS), by the Expert Panel of the Flavor & Extract Manufacturers Association (FEMA).
It is used as a flavoring agent in kool-aid, beverages, ice creams, candy, baked goods, gelatins, puddings, and chewing gum. Used in chewing gum and candy measured in parts per million is 2200 ppm.
The use of MA in fragrances is allowed by the Research Institute for Flavoring Materials (RIFM). One of the largest selling floral fragrances in the world uses MA as the important floral component. In this regard, it is not replaceable.
As a proactive method it depends on birds to be exposed to the repellent by flying through the fine aerosol mist or vapor-particles that are airborne. Mechanical vaporization machines that vaporize Avian Control relies on the exposure of the birds to the vapor. By vaporizing the product into extremely small particles called vapor-particles, the reaction from the birds is increased 2000%. This smaller vapor-particle reduces the amount of repellent being used and the cost of the application is better controlled. After several exposures to the vapor, the birds leave the area to find other roosting locations. As they return in 3-5 days and feel the vapor-particles are still in the air, they return less frequently. Automated aerosol systems inhibit any future re-infestation from new bird populations and assure a total bird free environment year ‘round. Use in mechanical aerosol equipment such as the automated Bird Buffer unit produces a finer aerosol that is more repellent to birds than previously thought.
Birds do not have to smell the product in order to obtain a reaction in their mucous membrane (called the trigeminal nerve). Birds sensitivity is far higher than previously tested. They react up to 700′ away if they fly into the vapor-particles that are air borne. By setting the timer to come on during the busy flight time of the birds (normally day time), the birds wait for it to go away. They continually try to find other areas to go to and within weeks, sometimes months, leave the area. When birds can’t see it, but they get a reaction to it, they can’t outsmart it, so they leave. This educational process takes 20-90 days in small areas, up to 3 months in larger areas. When clean up is done at the same time, this time frame is reduced dramatically. Pre-sensitizing the birds with the hand-held fogger will hasten the response time dramatically.
