What is the principal pest mosquito in Ohio?

The principal pest mosquito in Ohio is Aedes vexans. This species is widely distributed and is known to thrive in various habitats, making it a common and significant nuisance mosquito in the region. Aedes vexans is particularly adept at breeding in temporary water sources, which are prevalent in Ohio during the warmer months. This adaptability allows it to reproduce efficiently and contribute to its status as a primary pest.

This mosquito species is also known for its aggressive feeding behavior, which can lead to increased human-biting incidents. Its ability to transmit arboviruses (viruses spread by arthropods) further underscores its importance in vector control efforts, as public health concerns often focus on the potential for disease transmission.

In Ohio, Aedes vexans has an established population and is considered a key concern for vector control programs, emphasizing the need for effective management strategies to mitigate its impact on public health and quality of life for residents.
