Mosquito Awareness Week is April 16-22, and it is a reminder that it is more important than ever to eliminate standing water from your property. This year, the very active rainy season has left us with an abundance of mosquito breeding sites, from large flooded low-lying areas to small back yard sources.
In addition to native mosquito species, some of which can transmit West Nile Virus (WNV), the invasive Aedes aegypti mosquito has become established and is spreading in many areas of Ventura County. These small aggressive mosquitoes are day-biting, can breed in as little as a teaspoon of water, and have evolved to survive and thrive in and around our homes. Aedes aegypti mosquitoes have the potential to transmit several viruses, including dengue, chikungunya, Zika, and yellow fever. These viruses are not currently known to be transmitted within California, but now that these mosquitoes are present, an infected traveler returning to our area could be a source of local transmission.
