It's MOSQUITO AWARENESS WEEK! Let's spend this week learning about mosquitoes, mosquito-borne illness and what we do as your local mosquito District! Tune in to our social media pages for some helpful information!

The County of San Diego Vector Control Program will be doing routine aerial mosquito larvicide drops on June 24, 2026. If needed, continued treatments will be done on June 25. This will reduce mosquitoes and decrease the risk of West Nile virus. Learn more at SDFightTheBite.com.

Searching for and dumping out standing water sources around your home will help you have less mosquitoes around! Take a look around and see how many water sources you can find, dump them out, and remember to check them about once a week!

This invasive species, Gambusia affinis, or the mosquitofish, is used by our certified technicians to help residents get rid of mosquito larvae growing in artificial bodies of water. Each fish can eat hundreds of mosquito larvae each day, preventing mosquito problems and protecting people from diseases they spread. Because they are invasive, mosquitofish can only be placed in artificial bodies of water such as backyard ponds, fountains, animal troughs, or unused swimming pools. Visit SDVector.com to find our free distribution sites across the county.

In San Diego County we have about 30 different species of mosquitoes, including both native and invasive species. The invasive Aedes and native Culex mosquitoes behave a little differently and can also spread different diseases. Depending on which mosquito you have around (or both) you may need to check for different types of water sources to figure out where they may be coming from!

Were you surprised by the late rain in May? Mosquitoes love it. The rain followed by days of sunshine will provide opportunities for eggs to hatch. Lower your chances of producing mosquitoes by walking your yard and get rid of standing water. If you need ideas of where to look, check out our backyard checklist on our website, www.mosquitoes.org

If you have indoor plants or plant cuttings submerged in water, make sure to check the water for mosquito larvae weekly. Aedes aegypti mosquito lay their eggs on the walls of small water sources and having those little "ankle biters" indoors is no fun. Let's all keep the mosquitoes outdoors this summer!!

Male mosquitoes do not bite because they don't need to.
They don't need blood so their proboscis (the body part that drinks nectar and juices) cannot easily pierce skin. Thanks guys!
