Are Mosquitoes Overpopulated?

Mosquito populations have increased as much as ten-fold over the past five decades in New York, New Jersey, and California, according to long-term datasets from mosquito monitoring programs. The number of mosquito species in these areas increased two- to four-fold in the same period.

Is the mosquito population increasing?

This increase is most likely due to two factors: increased precipitation across the United States and public concern over mosquito-borne diseases like Zika and West Nile Virus (WNV). Increased or excessive moisture during the winter and spring, as seen in 2021, provides abundant habitat for mosquitos.

Is the mosquito population increasing or decreasing?

Mosquito populations have increased as much as tenfold, and mosquito communities have become two- to fourfold richer over the last five decades. These increases are correlated with the decay in residual environmental DDT concentrations and growing human populations, but not with temperature.
