Disney is Responsible for Protecting Guests
While most guests would say that mosquitoes are a nuisance that they can live with, Disney staff know that in addition to being loud and annoying, mosquitoes put people at risk for the very same pathogens that chickens are immune from. It’s why maintaining vigilance is Disney’s top priority. They know that with as many guests as Disney has each and every day, it would be very easy to spread a virus that was carried by mosquitos at the park.
