Is Bird Poop Dangerous: What To Know

“Is bird poop toxic?” is a common question, as it can contain harmful bacteria and fungi. Understanding the potential health risks associated with various aspects of the natural world is a key step in promoting human wellbeing and fostering positive interactions with our environment. One often-overlooked aspect of this is the potential risks associated with bird droppings.

While often seen as nothing more than an unfortunate byproduct of urban bird populations or a nuisance to car owners, bird poop can in fact pose a significant health threat if not handled properly. This article aims to demystify the topic, explore the potential dangers of bird droppings, and provide clear, expert guidance on how to mitigate these risks. 

Are bird droppings hazardous?

Bird droppings can be hazardous to humans due to the presence of bacteria, fungi, and parasites that are harmful to human health. Here are three primary concerns:

  1. Histoplasmosis: This is a respiratory disease that can be fatal. It results from a fungus growing in dried bird droppings and in soil contaminated with bird or bat droppings.
  2. Cryptococcosis: This is usually a harmless fungal infection, but it can become severe and even life-threatening for individuals with compromised immune systems. It’s caused by Cryptococcus fungi, which are often found in accumulated pigeon droppings.
  3. Psittacosis (Ornithosis/Parrot Fever): This is a rare infectious disease caused by a bacterium called Chlamydia psittaci, primarily carried by parrots, parakeets, and other similar bird species. Infection can occur when a person inhales dust that contains dried bird droppings that are infected with the bacteria.

Moreover, aside from direct health hazards, bird droppings can also cause property damage as their acidity can erode metals, stone, and paint.

It’s important to remember that while these risks are real, they are generally low for most people, especially those who aren’t regularly exposed to large quantities of bird droppings. 

Nevertheless, when cleaning up bird droppings, it’s advisable to use protective gear and to wash hands thoroughly afterwards to mitigate these risks. For large amounts of droppings or droppings in public areas, professional cleaning services with knowledge of the proper procedures and protective measures are often the best choice.

Structural & Aesthetic Damage

Bird droppings can cause both structural and aesthetic damage, primarily due to their acidic nature. Here’s a look at each:

  1. Structural Damage: The acid in bird droppings can corrode many types of construction materials, including metal, wood, stone, and concrete. Over time, this can lead to structural weakening and eventual failure if not properly managed. For example, bird droppings left to accumulate on a metal beam could corrode the beam over time, weakening the structural integrity of the building. Similarly, droppings left on stone or concrete surfaces can eat away at the material, causing pitting and wear that can be hazardous and costly to repair.


  1. Aesthetic Damage: From an aesthetic perspective, bird droppings can cause significant damage. They can leave unsightly stains on buildings, statues, cars, and other structures, which can be difficult to remove and can degrade the appearance of the object. Moreover, the corrosive effect of bird droppings can lead to the discoloration and degradation of various materials, negatively impacting their aesthetic appeal.

Cleaning bird droppings promptly and regularly can help prevent both structural and aesthetic damage. Professional cleaning services can provide safe, effective cleaning methods that minimise the potential for damage and maintain the integrity and appearance of structures. In the case of public or historic structures, or those with significant bird populations, long-term bird management strategies, such as deterrent systems or habitat modification, may be necessary to prevent ongoing damage.


Is cleaning bird poop dangerous: Health Risks

Bird droppings can present several health risks due to the pathogens they can contain. Exposure to these pathogens can occur through direct contact with droppings, inhaling dust from dried droppings, or, less commonly, through a bite from a bird carrying a pathogen. Some key health risks include:

  1. Histoplasmosis: This is a fungal disease that primarily affects the lungs and can potentially spread to other parts of the body. The Histoplasma fungus thrives in environments rich in bird or bat droppings. 
  2. Cryptococcosis: This is caused by the Cryptococcus fungus, which is often found in pigeon droppings. Like histoplasmosis, infection typically occurs through inhaling dust contaminated with the fungus. 
  3. Psittacosis: Also known as parrot fever, psittacosis is a bacterial disease that can be contracted from infected birds, including parrots, pigeons, ducks, and turkeys. 
  4. Salmonellosis: Birds can be carriers of Salmonella bacteria, which can be passed in their droppings. Humans can become infected with Salmonella by direct contact with bird droppings or by touching surfaces contaminated with droppings and then touching their mouth or food.
  5. E. Coli: Similarly to Salmonella, birds can also be carriers of E. coli bacteria, which can be passed in their droppings and pose a risk to human health if ingested.
  6. Avian Influenza (Bird Flu): While less common, some birds can carry strains of the influenza virus that can infect humans. Poultry and wild birds are the most common carriers. Direct contact with infected birds or their droppings can lead to infection in humans.


These risks highlight the importance of proper hygiene and protective measures when handling or cleaning bird droppings, especially in areas with high bird populations or where droppings accumulate. Those with compromised immune systems, the elderly, and the very young should be particularly cautious.

Is dried bird poop dangerous 

Dried bird poop can still pose certain risks, although the level of risk may be lower compared to fresh droppings. While the pathogens and parasites present in the droppings may become less active as they dry out, they can still retain their ability to cause infections under certain conditions. Here are some important points to consider:

  1. Inhalation of particles: When dried bird droppings are disturbed, they can release dust or particles that may contain pathogens. If these particles are inhaled, there is a potential risk of respiratory infections, such as histoplasmosis or cryptococcosis. It is advisable to wet the droppings before cleaning to minimise the release of airborne particles.
  2. Persistence of pathogens: Some pathogens can survive for extended periods in dried bird droppings. For example, the fungus responsible for histoplasmosis, Histoplasma capsulatum, can remain viable for months or even years. 
  3. Ectoparasites: Even in dried form, bird droppings can attract ectoparasites like mites and ticks. These parasites can remain active and pose a risk of infestation when they come into contact with humans. Care should be taken to avoid direct contact with dried droppings and to prevent ectoparasites from coming into contact with the skin.

While the risks associated with dried bird droppings may be somewhat reduced compared to fresh droppings, it is still recommended to follow safety precautions when cleaning them. This includes wearing protective gear such as gloves, a face mask, and safety goggles, as well as using damp methods to clean and minimise the generation of dust or particles.

If you are unsure about cleaning dried bird droppings or if there is a significant accumulation, it may be wise to consult a professional cleaning service or pest control experts who can handle the situation safely and effectively.

How long is bird poop dangerous 

The potential risks associated with bird poop, such as the presence of pathogens and parasites, exist as long as the droppings are not properly cleaned and handled. The duration of the danger depends on various factors, including the specific pathogens involved, environmental conditions, and the state of the droppings (fresh or dried). It is advisable to promptly clean up bird droppings and follow appropriate safety measures to minimise the risks.

Is bird poop dangerous to dogs 

Bird poop can pose potential dangers to dogs due to the presence of bacteria, parasites, and fungal spores. Contaminated droppings may contain bacteria such as Salmonella or Campylobacter, leading to gastrointestinal problems like diarrhoea and vomiting. Parasites like roundworms and external parasites such as mites or ticks can also be transmitted through bird droppings, causing infestations and skin irritations in dogs. Moreover, dried bird droppings can release fungal spores, which, when inhaled by dogs, can lead to respiratory infections like histoplasmosis.

To safeguard your dog’s health, it’s crucial to prevent them from ingesting bird droppings and to promptly clean up any encountered in their environment. Discourage your dog from sniffing or eating droppings during walks. When cleaning up, wear gloves and use a plastic bag turned inside out to avoid direct contact. Disinfect the affected area with a pet-safe disinfectant to eliminate any remaining pathogens.

Regular veterinary check-ups are essential for monitoring your dog’s overall health and addressing any issues related to exposure to bird droppings. During these visits, your veterinarian can conduct faecal examinations to check for any signs of parasitic infestation and provide appropriate treatments if necessary.

Steps for Safe Bird Droppings Removal

The safe removal of bird droppings is crucial in order to minimise the associated health risks. Here are the steps that should be followed:


  1. Protective Gear: First and foremost, it is crucial to wear appropriate personal protective equipment (PPE). This includes gloves, eye protection, a mask or respirator to prevent inhalation of dust or spores, and possibly coveralls to protect your clothes.
  2. Moisten the Droppings: Before cleaning, lightly spray the droppings with water to minimise dust that could be inhaled. This helps prevent any potentially harmful particles from becoming airborne.
  3. Removal Process: Using a plastic shovel or similar tool, carefully scoop up the droppings. If the droppings are on a delicate surface, a soft brush can be used to prevent damage.
  4. Disposal: Place the droppings in a sealed plastic bag before disposing of them in an outdoor trash bin.
  5. Surface Cleaning: After removing the droppings, clean the area thoroughly with a bleach-based solution to kill any remaining bacteria or fungi. Let the solution sit for around 20 minutes before rinsing.
  6. Wash Protective Gear and Tools: All the tools used and the protective gear should be cleaned thoroughly to avoid any cross-contamination. Disposable gear, like gloves, should be thrown away properly.
  7. Hand Hygiene: Lastly, ensure you wash your hands thoroughly with soap and warm water.


In the case of large accumulations of droppings or droppings in hard-to-reach areas like rooftops or high ledges, it may be necessary to hire professional cleaning services. These services have the proper training and equipment to safely and effectively remove bird droppings. Similarly, in the case of a bird infestation, professional pest control services may be required to address the source of the problem. Read more on our website Bon Accord Pest Control

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.
