Bio-Hazards Decontamination


Guano (rodent, bird & bat feces) and other organic matter (feathers, bones, body parts, carcasses, etc.) pose a health threat to human beings who come in contact with them or inhale the airborne particles from them. Every precaution should be taken to ensure that workers and building occupants are protected from the diseases carried or transported by rodents, birds and / or bats.

Enviro-Vac™ has been successfully removing bird guano hazard from factories, churches, high-rise buildings, hospitals and government buildings including owners of large and small properties since 1976.

Exposure to rodent, bird and bat droppings and nesting materials under ideal conditions can result in a number of diseases, including histoplasmosis, Newcastle disease, cryptococcosis, pseudotuberculosis and other avian transmitted diseases. Another major condition of concern would be hypersensitivity pneumonitis. This disease is generally contracted by inhaling a specific type of bacteria (thermophilic actinomycetes). The ubiquitous organisms, whose primary purpose is the decomposition or organic matter, have been isolated from manure, bird droppings, grain compost, hay, etc. Thermophilic actinomycetes are generally not a concern in the indoor environment. The presence of nesting birds in any portion of the building HVAC system and the potential introduction of the associated diseases that they cause become a real concern.

Dangers of Rodent Droppings

Some rodents are infected with a type of hantavirus that causes (HPS). Deer mice (plus cotton rats and rice rats in the Southeastern states and the white-footed mouse in the Northeast) are the rodents carrying hantaviruses that cause hantavirus pulmonary syndrome. These rodents shed the virus in their urine, droppings and saliva. The virus is mainly transmitted to people when they breathe in air contaminated with the virus. This happens when fresh rodent urine, droppings or nesting materials are stirred up.

These possibilities demonstrate why disinfecting rodent-infested areas is so important in preventing transmission of the viruses.
