Mosquitoes, Hurricanes, and Flooding: What You Need to Know for Post-Storm Protection


As the winds howl and the rain pours during a hurricane, one might think that mosquitoes would be the last thing on anyone's mind. However, the aftermath of a hurricane can bring about conditions that lead to an unexpected surge in mosquito populations. Old Towne Termite and Pest Control wants to ensure that you are well-informed about the connection between mosquitoes, hurricanes, and flooding, and how you can protect yourself and your loved ones from the potential impacts.

The Aftermath of a Hurricane: Floodwater Mosquitoes

In the wake of a hurricane, the immediate concern is often the destruction caused by high winds and flooding. While adult mosquitoes do not generally survive the high winds of a hurricane, flooding that follows can have a significant impact on mosquito populations. Mosquito eggs laid in the soil by floodwater mosquitoes during previous floods can hatch due to the increased moisture. This leads to the emergence of large populations of floodwater mosquitoes, which are primarily considered nuisance mosquitoes.

Understanding Nuisance Mosquitoes and Disease Spread

Nuisance mosquitoes, while aggressive biters, do not typically spread viruses that can make people sick. Most of the mosquito species that can transmit diseases require time to develop and increase in numbers. It's generally about two weeks after a hurricane that areas that did not flood but received substantial rainfall might see an increase in these disease-transmitting mosquito populations. However, it might take several more weeks before these mosquitoes start to spread viruses to people.

Rainfall, Hatching, and Virus Transmission

Increased rainfall, a common occurrence during and after a hurricane, can lead to a rise in mosquito egg hatching. If you live in an area with ongoing transmission of viruses like chikungunya, dengue, West Nile, or Zika, the risk of getting infected can increase due to the larger mosquito populations. Taking steps to protect yourself and your family from mosquito bites becomes crucial during this period.

Post-Storm Precautions: Protecting Yourself

With people spending more time outdoors for cleanup after a hurricane or flooding, the chances of being bitten by nuisance mosquitoes rise. While these mosquitoes don't usually transmit viruses, their aggressive biting can lead to discomfort and itching. Using long-sleeved clothing, EPA-registered insect repellents, and treating clothing with permethrin are effective ways to protect yourself.

Managing Mosquitoes Post-Storm

The rise in floodwater mosquito populations can pose challenges to recovery efforts, as outdoor work becomes more difficult. Professional mosquito control measures, including insecticide use, can help reduce mosquito numbers in affected areas.

Reducing Mosquito Breeding Sites

After a hurricane or flood, health departments and mosquito control districts often step in to control mosquito populations. Residents can contribute by taking measures to eliminate mosquito breeding sites around their homes. Regularly emptying and scrubbing items that can hold water, such as tires, buckets, and containers, helps prevent mosquito eggs from hatching. Ensuring that windows and doors have screens and using air conditioning when possible can also keep mosquitoes outside.


While hurricanes and flooding demand our immediate attention for their potential devastation, the resurgence of mosquito populations in the aftermath is a crucial consideration. By understanding the behavior of floodwater mosquitoes, differentiating between nuisance and disease-transmitting mosquitoes, and implementing protective measures, you can ensure the safety and comfort of your family post-storm.
