According to Gary Goodman, District Manager of Sacramento Yolo Mosquito and Vector control, many residents are anxious and excited to get outside and enjoy the warm weather so it's important to protect yourself from mosquito bites by wearing a good mosquito repellent.
The Centers for Disease Control and Prevention (CDC) recommend using an insect repellent that contains the active ingredients DEET, Picaridin, IR3535 or the plant-based oil of lemon eucalyptus.
Aside from personal protection against mosquito bites, it's important to ensure mosquitoes are not breeding at home. Drain stagnant water from sprinklers, irrigation, and rainstorms. Be sure to check your backyard and dump any water in flower pots, kiddie pools, tires, pet dishes, bird baths and other common household containers that can hold water.
Another ongoing concern is the invasive mosquito Aedes aegypti which has been detected in several counties throughout Southern California and the Central Valley. For county level information, see this map. Invasive mosquitoes pose a significant health threat because they can transmit dangerous viruses including Zika, dengue fever and chikungunya. Surveillance efforts have continued since the initial detection last August. To date, no cases of Zika virus have been reported in California.
For more information on mosquito identification and management, see our recently revised Pest Notes: Mosquitoes. Additional information on vector-borne diseases is available on the California Department of Public Health website.

In Part I, we discussed why mosquitoes bite, and which mosquito species can spread West Nile and Zika virus. Now, let's talk about what mosquitoes need to reproduce, how to prevent them from breeding around your home, and best methods to protect yourself and your family while outdoors.
What do Mosquitoes Need to Breed?
The mosquitoes that spread West Nile virus and Zika need water to lay their eggs. Female mosquitoes can lay their eggs in even the smallest amount of water. Places in your yard that appeal to them include standing water found in ponds, garden pots, children's toys, or even pet water bowls. Eliminating these possible breeding spaces is key to mosquito control.
Watch the video “Don't Let Mosquitoes Breed in your Yard” from UC IPM for helpful tips.
Protect Yourself from Mosquito Bites
There's a plethora of mosquito control and prevention items for sale, but many are ineffective.
When outdoors, protect your skin by wearing long-sleeved pants and shirts, long socks, and a hat. Be aware that mosquitoes can bite through a thin layer of clothing. Also, choose and apply an effective EPA-registered mosquito repellent that contains DEET, picardin, IR3535, or oil of lemon eucalyptus to exposed skin.
You may be tempted to use outdoor sprays to battle mosquitoes. However, this method is only temporary and doesn't help control the source of the problem. The best way to avoid bites are prevention and protection.
