Ohio Mosquito Season

Ohio doesn’t really spring to mind when we think of mosquito-heavy states, but it is quietly plagued with them: two of Ohio’s three largest cities (Cleveland and Cincinnati) were included in Orkin’s Top Mosquito Cities for 2021. Ohio’s largest city, Columbus, also made the list in 2017.

There are about 60 different species of mosquitoes in Ohio, and while most deliver irritating but ultimately harmless bites, several are capable of transmitting serious, possibly even fatal diseases, such as encephalitis and malaria.

When are Mosquitoes Active in Ohio?

Mosquitoes are active in the warmest months, usually May through October. Mosquito activity will die down after the first frost in the fall. Generally speaking, mosquitoes are most active around sunrise and sunset since direct sunlight and high midday temperatures can easily dehydrate them. This is why keeping your grass relatively short helps keep mosquitoes at bay—they are unable to effectively hide from the sun’s rays.

Common Mosquito-Borne Diseases in Ohio

Mosquito-Borne diseases are always a concern, no matter where you live. Mosquito diseases that occur locally in Ohio include the following:

Common Mosquito Species in Ohio

Culex Pipiens (Northern House Mosquito)

These brown mosquitoes of medium size have cross bands of white scales on the abdominal segments, but have no other prominent markings. They commonly enter houses, and are vectors of SLE.

Aedes triseriatus (TreeHole Mosquito)

These black mosquitoes have silvery white scales at the sides of the thorax. They breed mostly in tree holes, tires and other artificial containers. Aedes triseriatus is the principal vector of LaCrosse encephalitis in Ohio.

Aedes vexans

Considered the principal pest mosquito in Ohio, this medium-sized brown mosquito has narrow rings of white scales on the hind tarsi and a “V” shaped notch at the middle of each band of white scales on the upper surface of the abdomen. This mosquito is very abundant and breeds in rain pools, flood waters, roadside puddles, and most all temporary bodies of fresh water.
