Are there mosquitoes in Hawaii and why?

Though it may come as a surprise to some, there are mosquitoes in Hawaii. They can be found on all of the major Hawaiian Islands. According to folk belief, they were introduced from bilge water carried in whaling ships in the early 19th century.

The reasons are listed below:

  • Climate: The weather in Hawaii is the perfect climate for mosquitoes to thrive. The hot and humid weather is ideal for them to breed, and so they are present in Hawaii during the summer and fall months
  • Standing water: Mosquitoes thrive in standing water, and Hawaii has plenty of that during the rainy season. Mosquitoes lay their eggs on the surface of standing water, which is necessary for the egg’s development into larvae. The larvae live at the bottom of the pool and later develop into mosquitoes.
  • Saltwater: Saltwater in Hawaii is the reason for existing of mosquitoes in Hawaii. Mosquitoes need a saltwater habitat to breed, and they are most commonly found near coastal areas.
  • Topography, and ocean currents: The rough, mountainous terrain creates many different habitats that are perfect for mosquitoes to live and breed in. The ocean currents bring warm water to Hawaii, which creates the perfect conditions for mosquitoes to thrive.
  • Volcanic eruptions: The hot, moist environment created by the volcanoes is perfect for mosquitoes to breed and grow. In addition, the ash and debris from the eruptions can provide a food source for the mosquitoes.
