Based on the information gathered after Hurricane Katrina, in the aftermath of Hurricanes Harvey Irma and Maria there will be several effects on the mosquito population and the prevalence of arboviruses that are transmitted by mosquitos such as Zika, dengue, and West Nile. Texas and Florida are the two states with the most breeds of mosquito, both with over eighty mosquito species. Texas and Florida also are warm states, with temperatures often over 79 degrees promoting mosquito activity.

Female mosquitos can lay up to 300 eggs at a time. The eggs are usually deposited in clusters on the surface of stagnant water, or laid in areas that regularly flood. Winds and floods from a hurricane will wash away containers that would have functioned as breeding grounds, resulting in an immediate decline in local mosquito population. In the days and weeks after a hurricane, while flood waters are receding, the mosquito population will recover. The amount of standing water in Texas and Florida has increased in the weeks after the recent hurricanes. Standing water now may be found in houses, yards, and streets. Almost any receptacle could become a mosquito breeding ground if filled with flood water. A Tulane University study reported that in the year after Katrina the number of reported West Nile cases more than doubled in some communities affected by the hurricanes.
