Invasive Aedes mosquitoes are not native to San Mateo County, California, or even North America. They do not belong in our ecosystems, and they can make people very uncomfortable because they bite during the day and even bite indoors. More importantly, they are a risk to human health because they can carry diseases that make people very sick, like Zika, chikungunya, dengue, and yellow fever.
Mosquitoes might seem like an annoying nuisance, but did you know they can transmit diseases that can make you sick? It only takes one bite from a mosquito infected with a disease like West Nile virus to put you at risk for serious illness.
