Psychology is for the birds.

By allowing a flock of birds to sit on a roof or a building's ledges, there is a very real danger of building deterioration, corrosion, and roof cave-ins, costing building owners tens of thousands of dollars in repairs and repetitive cleanup efforts.

However, this type of damage to buildings can be avoided by utilizing a very basic psychological concept--Operant Conditioning.

Operant Conditioning uses an electric shock as the stimulus to decrease the likelihood of a particular behavior being repeated, such as a bird landing on a building.

Bell Environmental has applied this theory and created a unique track system called the Bell Strip. This strip permanently displaces birds by applying a powerful yet non-lethal shock, thereby training the birds to stay off the building.

Buildings all over the country that utilize the Bell Strip will no longer suffer from the significant structural damage due to the acidity and weight of bird droppings.

The Bell Strip system is able to displace birds by giving them a powerful, yet non lethal, shock upon landing on the electric device--causing the bird to be uncomfortable enough that it is forced to move off of the building.

Similar to cattle fences that ranchers use to keep their livestock from wandering off, the strip alters the bird's behavior over a period of time through the electric shock--teaching the animal to never land on the building.

The Bell Environmental track system is 100-percent effective. Once installed, buildings never have to worry about birds causing damage because they will eventually learn not to land on a particular building because they will get shocked.

The Bell Strip can be manufactured to match the exterior of any building--making it almost completely unnoticeable to the naked eye. Additionally, the device lays completely flat adding to its discreetness.

This device can also help prevent disease-causing organisms commonly found in bird droppings from spreading to the building's occupants.

Known as "Sick Building Syndrome," more than 60 diseases associated with pest birds can be spread to thousands of people simultaneously by allowing bird droppings to accumulate in or near HVAC systems.

These systems can then easily spread disease-causing organisms to every occupant in the building. In many instances, tenants of "Sick Buildings" are at risk for serious and sometimes life-threatening illnesses.

Bell Environmental's recently launched website www.birdcleanup.com outlines all the potential health hazards associated with bird droppings.
