Contamination of Food and Manufactured Goods
Droppings, feathers, and debris from birds roosting overhead in warehouses or factories can contaminate food that is being packaged or stored. Transference of contaminates can start at any warehouse and spread anywhere which is why it is so important to keep all buildings bird free.

Air Handling Equipment
Many "sick" buildings have traced their problems to birds. Contaminated dust is often brought into a building through air handling equipment. With over sixty diseases attributed to birds, its more important then ever to keep rooftops and air conditioning & heating equipment bird free.

Transference by Parasites
Fleas, ticks, mites and other ectoparasites thrive in and around bird nestings and accumulated droppings. These pests than infiltrate buildings and spread diseases through numerous methods. Because of this, cleanup of bird infested sites should be the first priority and completed before a full barrier program is completed. All bird droppings should be considered hazardous waste! Cleanup & disposal should only be completed with protective clothing and droppings disposed of properly.

Direct contact with feces.
Bird droppings anywhere should be considered hazardous waste. Any direct contact can spread disease.
