Diseases Spread By Pest Birds

Diseases Spread By Pest Birds

Flight has got to be the greatest gift bestowed upon birds. At the same time, this ability to journey across long distances and through a multitude of landscapes, poses a really great setback!

What is that you ask? Birds are exposed to a series of microorganisms that can be particularly dangerous, and as a result, play a role in the spread of infectious diseases to humans.

Wild birds are carriers of bacterial (e.g. listeriosis & salmonella), chlamydial, mycotic, parasitic, protozoal (e.g. toxoplasmosis & trichomoniasis) and rickettsial diseases, as well as dermatosis.

The amplification in the number of diseases transmitted by birds to humans over the last decade has been unparalleled, for example outbreaks of Avian flu and the West Nile Virus.

If you’re concerned about the potential diseases that can be caused by migratory birds, contact us on  for further advice on our bird control solutions or to schedule a FREE inspection of your premises.

Migratory Birds & Their Role In Disease Transmission

Migratory birds have the potential of transmitting over 60 diseases, illnesses and infections to humans and several more to domestic animals, as a result of bird droppings, feathers and debris under a roost.

The transmission of these diseases are generally spread by:

• being in contact with droppings,
• inhalation of air-borne fungi that originates from droppings,
• parasitic transferral or;
• food & water contamination

Human Diseases That Can Be Contracted Through Contact with Bird Droppings

These diseases have been known to be associated and spread by wild birds:

Lyme Disease

Lyme disease is the most common tick-borne disease in the northern hemisphere.

While it can be spread by migratory birds that play host to the ticks, it is also spread by deer populations in the United States.

West Nile Virus

The West Nile virus is a disease spread by mosquitoes. It is spread when a mosquito bites and infected bird and then bites a human.

Mosquitoes carry the highest amounts of the virus in early fall, and the risk of contracting this disease drops as the weather becomes colder and mosquitoes die off.

The most affected are the young, elderly, pregnant women and people with immune system deficiencies.

Avian Influenza

Avian flu or bird flu is a highly pathogenic avian influenza. It is usually contracted from either handling dead infected birds or from being in contact with infected fluids, like bird droppings.

H5N1 is an emerging avian influenza that has been causing concern on a global scale as a potential threat due to the increase number of bird-to-human transmissions.


Soil and bird droppings are among the sources of infection which can result in meningitis.

A large percentage of the migratory bird populations are carriers. Quite similar to histoplasmosis.


Contracted through inhalation of fungal spores in bird droppings. The most affected are the young, elderly and people with immune system deficiencies.


Bacterial infection that can be transmitted via droppings, feathers and eggs and which is typically either inhaled or ingested.

This is by no means a comprehensive list of the diseases that can be transmitted by migratory birds.

While bird proofing and deterrent measures cannot completely prevent or stop migratory birds playing a role in disease transmission, what they do offer is a minimal amount of contact between these disease carrying pests and humans.
