Invasive Aedes mosquitoes in San Mateo County

A female Aedes aegypti mosquito lands on a human hand and prepares to bite.

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: it only takes ONE

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.

Why Control Mosquitoes?

Mosquitoes are more than a nuisance! They can carry and transmit diseases that can make people very sick. Even when they don’t transmit disease, their bites may be uncomfortable or become infected.

Controlling mosquitoes interrupts the disease transmission cycle and protects people from disease.
