Invasive Aedes

AedesDoorhanger-Final_thumbWARNING: Invasive Aedes mosquitoes have been found in Shasta County. We need your help!

Recently the Shasta Mosquito and Vector Control District detected Invasive Aedes mosquitoes in our area. Zika, dengue, and chikungunya viruses are spread to people through a bite of an infected Aedes mosquito. They are aggressive daytime biters and can also bite at night.

To lower your risk, get rid of places where mosquitoes lay their eggs and grow. Aedes mosquitoes are “container breeders” and prefer to lay eggs on the inside of water-filled containers or on stems of plants growing in water. These eggs can survive for YEARS, even when dry. Any item that can hold a teaspoon of water or more can grow mosquitoes.
