The peak season for mosquito activity is typically observed during the spring and summer months due to several key environmental factors. During this time, warmer temperatures create an ideal climate for mosquitoes to thrive. The increased warmth accelerates their breeding cycles and allows larvae to develop more quickly in standing water, which is essential for their reproduction.

Moreover, spring and summer generally bring more rainfall, leading to the formation of stagnant water pools where mosquitoes breed. The abundance of food sources, such as plants and animals, further supports their life cycle in these months. This combination of favorable weather conditions and abundant breeding sites results in a significant increase in mosquito populations, making spring and summer the peak seasons for their activity.

In contrast, during the winter months, the cold temperatures and potential frost can significantly reduce mosquito activity, as many species enter a dormant state or die off. Similarly, fall months see a decline in activity as temperatures drop and breeding diminishes. While some mosquito species may be present year-round in warmer climates, the majority experience a notable peak only in spring and summer.
