Even years after bats have left a building, the feces and urine pose an incredible threat to human health. It is not advised to disturb bat guano without the proper protective equipment as it may release spores or dust from fungus.

Where Is Bat Guano Found

Bat guano is the technical name for bat poop. Bats like to live in older brick structures as the brick holds heat and small holes in wood or brick allow them access to empty attics, roof areas, barns and chimneys. Bats will deposit guano and urine just before their roosting area. If the guano is on wooden structure, it can cause rot and increase access of bats and spread of the guano.

Why Is Bat Guano Dangerous?

Along with Rabies, bats can contract Histoplasmosis. This infectious disease is caught by inhaling fungal spores that cause the disease. The fungus is passed through the bat into the animal's feces and as the fungus thrives in the moist environment it produces more spores that become airborne as soon as the feces pile is disturbed. It is very important to not move or sweep up bat guano as this activity creates airborne spores that are inhaled and can lead to Histoplasmosis.

What Are the Signs of Histoplasmosis?

This disease is caused by airborne fungal spores which are breathed into the lungs. The disease first affects the lungs within the first few days of being in contact with the fungus. A little over one week later you symptoms may appear to be those of the common flu: cough, headache, fever, chest pain, loss of appetite, cough, headache. Extreme symptoms can include shortness of breathe, impaired vision and joint and muscle pains. For some people, symptoms of Histoplasmosis may pass. Others may have to receive treatment with anti-fungal medication.

If you have a weakened or compromised immune system, Histoplasmosis could be significantly more dangerous to your health. This can be true of the elderly, the very young, and smokers. Histoplasmosis in these cases can lean to long-term illness that can take years to treat and have symptoms similar to tuberculosis. In extreme cases, this illness can be fatal.

Dealing with Bat Guano

Because the Histoplasmosis spore is invisible, odourless and airborne, proper respiratory equipment is necessary when cleaning up bat guano. When disturbed, spores can attach to clothing and can become airborne even after you are nowhere near the cleanup site. It is strongly recommended that you contact professionals like AGS Environmental to deal with this dangerous fungus containing animal waste.

Asbestos Removal

The presence of Asbestos in commercial buildings and residences is becoming more and more of a concern for Canadians. Our crew are specialists in the abatement of Asbestos and are the most efficient in the business.


Mould Removal

Certain conditions and environments can lead to the growth of particularly harmful strains of mould in buildings. If left unchecked, these toxic moulds can lead to serious health problems for the occupants of the building.


UFFI Removal

Formaldehyde vapours emitted by the curing process of urea formaldehyde foam insulation (UFFI) as well as from the breakdown of old foam are a known lung, nose, throat and eye irritant. This insulation style was used extensively in homes in the 1970s.


Lead Paint

Exposure to lead has decreased over the years but lead is still found in many environments due to its use in paints, gasoline, solder and pipes for decades before the 2000s. Lead is a dangerous neurotoxin and lead dust is easily absorbed into the blood through the lungs.


Disaster Recovery

When weather or bad plumbing has caused flooding which has caused a contamination issue, our recovery services can help clean up your building and get you back into it as soon as possible. AGS Environmental is ready to roll 24 hours a day, 7 days a week to help with your disaster restoration.


Sandblasting Services

Sandblasting is used to clean surfaces, remove rust, oxidation, or finishes and to prepare surfaces for new coating applications. This process thoroughly removes the material without harming the substrate and consists of propelling an abrasive media at high velocity via compressed air onto the surface to be cleaned.



Polychlorinated Biphenyls (PCBs) pose significant human health risks with exposure. Links to digestive cancers, reduced fertility and neurological problems are all symptoms of exposure. Production of PCBs was terminated before the 1980s because it was discovered they do not break down and can build up in the environment.



Many industrial processes, landfills and incineration activities release mercury into the environment. This neurotoxin has the potential to cause damage to speech, hearing, walking and muscle strength. Mercury was also used in fungicides, preservatives and liquid mercury was used in gauges and meters of industrial and commercial equipment.


Sample Testing

We're proud to now offer independent sample testing. Our labs can verify if the mould, or material sample of potential asbestos, PCB or other toxin is a danger to your building and the occupants within. Call us to have your material tested!
