Minnesota residents who travel to other countries can return with mosquitoborne diseases such as malaria, dengue, chikungunya, yellow fever, and zika virus. Of course, many other factors are involved, such as the availability of food and other resources influencing the size of bird populations; the availability of sites for the development of mosquito larvae, which influences the size of mosquito populations; as well as weather, including rainfall and temperature. This type of application is more localized and less demanding than fogging with regard to environmental conditions and expense. Once infected by a mosquito bite, the reservoir species are usually not seriously affected. Some people with dengue develop complications that can result in internal bleeding, shock and even death.
