Birds can spread disease, thus posing a significant health and safety issue. This is especially true if you prepare or manufacture food on your premises. In addition, some birds can be quite aggressive which can pose a threat to your household or customers. Furthermore, their droppings are acidic and can cause damage to property, while their nests can pose a fire risk if positioned close to electrical wires, or in chimneys with open fires. Furthermore, nests near air conditioning systems can also pollute the system.

Essentially, many birds are flying vermin and due to their nature, they can be difficult to control without having professional measures put in place.

The types of disease they can spread to humans include both airborne and food-borne diseases such as Cryptococcus neoformans, Histoplasma capsulatum, Salmonella, E. coli, Listeria monocytogenes, Vibrio cholerae and Chlamydia psittaci, to name a few.

Types of birds that cause a nuisance include:

Pigeon - Gull - Jackdaw - Crow - Magpie  

Sparrow - Starling - Raven
