Many articles address the unhealthy living conditions and property damage that an infestation can cause. However, the health risks linked to rodent or bird infestations are more rarely covered. Still, many diseases can be transmitted to humans if they are in contact with these pests or even simply with their droppings.

It therefore makes sense to investigate the matter to learn about the real health risks associated with pest droppings.

Diseases transmitted via rodent droppings

Rodents such as mice and rats often leave feces in their path that can contain bacteria, contaminate food and cause allergic reactions.

These mammalian droppings are also known to be a vector for the spread of certain diseases.


Hantavirus is a potentially fatal disease transmitted to humans by rodents, mainly the white-footed deer mouse. People can become infected from exposure to urine or feces of infected rodents.

The chances of contracting hantavirus increase when people are near areas where rodents are actively living. This is why if you think rodents have settled in your home, it’s best to seek the services of an extermination specialist before the droppings accumulate in large quantities.


Salmonellosis is a type of food poisoning that can be transmitted through rodent feces containing the bacteria that causes it: Salmonella. Symptoms include diarrhea, fever and abdominal pain.


Leptospirosis is a disease that is contracted following exposure to bacterium of the genus Leptospira. It can be found in the urine of many animals, including rats.

Health risks linked to bird droppings

The most serious human health risks associated with bird infestations come from pathogenic organisms that can develop in the build-up of nutrient-rich bird droppings, feathers and debris.

Several diseases are linked to contact with bird droppings.


Histoplasmosis is a life-threatening respiratory disease. It is caused by a fungus that grows in dried bird droppings.


Cryptococcosis is caused by yeasts found in the intestines of pigeons and starlings. The disease often begins with lung problems and can then affect the central nervous system.

Infection with E. coli bacteria

This is one of the most common infections caused by enteric bacteria. E. coli is often found in bird droppings. Although not everyone who comes into contact with the bacteria will have symptoms, some will suffer from severe stomach cramps, vomiting and diarrhea.
