Why are the mosquitos bad some years and good some years?

In general, the weather and available mosquito larval development sites affect the amount of mosquitoes in an area.

When we have a lot of standing water available there is typically more mosquito larva produced.

Cycles of wet weather to hot weather to wet weather again tend to produce more mosquito hatches and result in a bad year. Conversely, if we have a cool, wet spring followed by a hot and dry summer there are fewer mosquitoes and it is considered a good year.
