Almost universally, mosquitoes avoid direct sunlight and heat in the middle of the day.

Where Are Mosquitoes Most Active?

Mosquitoes are found throughout the United States. Mosquito habitats are near standing water and in a shaded area. Female mosquitoes lay eggs in shallow, stagnate water. Mosquito eggs can be found in marshes, lakes, ponds, birdbaths, tires, children’s toys, gutters, and pools.

Mosquitoes avoid direct sunlight. Shaded areas from trees, bushes, or even tall grass provide shelter for mosquitoes.

Mosquito Season

Mosquitoes are most active during the warmer months. When temperatures dip below 50 degrees Fahrenheit, mosquito activity plummets. Some species hibernate; while other species die off.

When mosquito activity is high, you are more likely to get a mosquito bite. More than just an annoyance, mosquito bites can also transmit diseases like yellow fever, Dengue, West Nile virus, and Zika virus.
