administrators, lawn maintenance companies, not to mention

environmentalists and animal rights supporters, DCV's new "Flight

Control(tm)" Bird Repellent

areas without harming them

Breakthrough product from DCV is now available for immediate

delivery from its exclusive sales agent, LESCO, at 1-800-321-5325.

The world's first environmentally friendly, safe and effective bird repellent has been developed by DCV, Inc., the same world-leading life science company that recently introduced BioChoice(tm) Immune Support dietary supplement support for the human immune system.

Today's market introduction of "Flight Control(tm)" Bird Repellent, which has already been approved by the EPA for repelling geese, underscores DCV's commitment to develop a wide variety of biotechnology, food and life science products that make a meaningful contribution to improving the health and quality of life for people and animals.

"Any airport operator in the world will tell you that bird control is one of the most vexing problems they face today," said Ken Ballinger, who developed Flight Control for DCV. "For years, the industry has been trying to develop an effective product that's also safe and environmentally friendly. With the commercialization of Flight Control, however, the airports now have an important and effective tool for dealing with birds."

Developed specifically to meet the needs of airport operators, Flight Control has been tested by the U.S. government at airports and at other field trials, where it has proven to be an effective part of their bird strike program. "It pushes birds back from runways and surrounding areas and keeps them off of them," Ballinger asserted. "With over 2400 reported incidences of bird strikes with aircraft last year alone, it is clear that airport operators need an effective, environmentally friendly solution."

Unlike traditional bird repellents -- including taste repellents, frightening agents, chemical agents and bird predators -- Flight Control is a safe, naturally occurring product that is environmentally friendly and is harmless to people, vegetation, birds and other animals. It can be mixed with water for easy spray application, but does not dissolve in water. As a result, it can remain active on the surface where it is sprayed for up to several months regardless of weather conditions. Birds that ingest Flight Control experience a harmless irritation that is far more powerful than taste repellents. What's more, birds can detect it from a great distance and in very low concentrations -- helping to ensure that they stay away from the area.

"Flight Control can be used by any parks and country club administrator or lawn maintenance company that needs to effectively repel birds without harming them or the environment," Ballinger concluded. "We're proud to bring this breakthrough product to market."

Flight Control is available for delivery from DCV, Inc., through its authorized sales agent LESCO at 1-800-321-5325.
