When Are Mosquitoes Active in North Carolina?

Mosquitoes are more than just a nuisance; they can also pose health risks by spreading diseases like West Nile virus, Zika virus, and Eastern Equine Encephalitis. For homeowners in North Carolina, understanding when mosquitoes are most active can help you protect your family and home from these buzzing pests. In this blog, we’ll dive into the mosquito season in North Carolina to help you avoid these times and prevent itchy mosquito bites.

What Time of Year Are Mosquitoes Active in North Carolina?

Mosquitoes in North Carolina are typically most active from late spring through the fall, but their exact activity depends on temperature, humidity, and rainfall patterns. Here's a more detailed look at the seasons and factors that influence mosquito activity:

Spring: April to June

As temperatures rise in early spring, mosquitoes begin to emerge from their winter dormancy. Spring in North Carolina can be unpredictable, with temperature swings, but as the weather warms, mosquitoes start to become more active, particularly in areas near standing water. Puddles, rainwater in containers, and natural bodies of water provide ideal breeding grounds. In addition to standing water, learn what else may attract mosquitoes to your yard.

• Peak Mosquito Season: While mosquitoes are present, they are not yet in full force. Activity will increase as the temperature stabilizes.

Summer: June to August

Summer is peak mosquito season in North Carolina. With average temperatures in the 80s and frequent rain showers, mosquitoes thrive during this time. The humid climate, combined with abundant standing water from summer rains, creates perfect breeding conditions.

• Most Active Time: Mosquitoes are most active during the early evening and early morning hours. This is when temperatures are cooler and humidity is high, which makes these times ideal for mosquitoes to feed.

Fall: September to November

Fall in North Carolina can feel like a second summer, but by September, cooler temperatures start to reduce mosquito activity. However, mosquitoes are still active through early October, especially if the weather is warm and humid.

• Activity Decline: As temperatures dip in late fall, mosquito activity begins to taper off. However, in warmer parts of the state, mosquitoes can still be a concern until the first frost.

Winter: December to March

During the colder months, mosquito activity slows to a halt. Most adult mosquitoes die off with the arrival of winter’s first frost. However, some mosquito species, like the Asian Tiger Mosquito, can survive the winter in a dormant state. They may start becoming active again as early as March, particularly in the southern parts of the state where temperatures are milder.

What Time of Day Are Mosquitoes Active in North Carolina?

In North Carolina, mosquitoes are typically most active during the early morning and dusk to evening hours. Here's a breakdown of their activity patterns:

Early Morning (Dawn)

Mosquitoes are active as soon as the sun rises, especially when temperatures are cooler and the humidity is high. This is often the first peak time for mosquito activity, as they emerge from their resting spots to feed.

Midday

During the heat of midday, mosquitoes tend to be less active because it's often too hot for them to function efficiently. However, in areas with consistent shade or abundant water, mosquitoes may still be present and active.

Evening and Dusk

The second peak of mosquito activity occurs during the dusk to evening hours, right before sunset. As the sun sets and temperatures cool down, mosquitoes are highly active and seeking out hosts to feed on. The low light and humidity during this time make it an ideal time for mosquitoes to be out.
