Very rarely are native birds a problem in industrial buildings or installations. There are some exceptions, for example, corellas or cockatoos damaging or fouling electrical and radio transmission stations and towers. These birds are easily repelled using Bird Gard's unique harassment sounds transmitted from speakers placed on or near the towers.
Usually the main pests within or on buildings and warehouses are pigeons and starlings, sparrows, swallows and sometimes seagulls, crows and cockatoos. The main problem presented by these birds is one of health considerations, particularly where people are working in areas where the bird's droppings accumulate. Other problems include droppings fouling an area or a product and blatant destruction of property (vandalism). These birds can also harbour several diseases harmful to humans. Bird Gard systems have proved to be extremely effective in removing such problem birds.
Rodents, either rats or mice, are a simple fact of life. They thrive wherever man does and have followed him to all parts of the globe.
Virtually every house, restaurant, warehouse, factory, food processing plant, storage shed, silo, barn, produce store and even ships at sea have a resident rodent population.
Poisons can kill them but as soon as one rodent is killed another takes it's place. Besides, places where food for human consumption is stored or prepared may not be allowed to place lethal poisons (for obvious reasons). Poisons can also kill pets or come in contact with unsuspecting infants.
Rats and mice have quite a small territory - they don't travel very far from their nest. Using our ultrasonic (very high frequency) rodent repellers, rats and mice will leave the immediate area completely and find a new residence elsewhere. They cannot tolerate the variable (changing) frequencies constantly bombarding their highly sensitive hearing. Rodents can hear up to 55,000hz. Humans hear up to around 20,000hz. These high frequencies are the same as the ultrasound used in hospitals all over the world.
Humans rarely hear them yet rodents can. If rats or mice have young in a nest and a good food source is at hand, it may take a week to 10 days for them to permanently move out.
