All of the public health materials we use to control mosquitoes are registered​​ with the US Environmental Protection Agency (EPA) and are regulated by the California Department of Pesticide Regulation and Los Angeles County Agricultural Commissioner / Weights and Measures . For details regarding materials' research to registration, please contact the manufacturers. The materials are chosen based on their ability to be effective against mosquitoes and have minimal risks to humans, pets, and the environment. These treatments are usually made with a truck-mounted applicator that disperses an ultra-low volume mist into the air. The mist's droplets are small enough to target mosquitoes. If weather conditions are not favorable, or if there are operational delays, the treatment may be postponed or delayed. Treatments may continue or resume in the following weeks with continued high mosquito populations or disease activity.

Dengue is a viral disease caused by any of the four related viruses: dengue virus 1, 2, 3, and 4. Dengue viruses are spread to people through the bite of an infected Aedes mosquito. A person can be infected with dengue multiple times in their life. The most common dengue symptom is fever with: Aches and pains (eye pain, typically behind the eyes, muscle, joint, or bone pain) Nausea, vomiting Rash If you feel you are experiencing dengue-related symptoms, please contant your primary care doctor. Can Dengue be contracted from person-to-person? No. Dengue can only be transmitted through the bite of an infected mosquito. A person infected with Dengue during pregnancy can pass the virus to their fetus. Dengue is not passed from female mosquito to mosquito offspring. Visit the CDC website to learn more about how dengue spreads: LEARN MORE How to reduce the risk of acquiring Dengue Fever? The best way to prevent acquiring dengue is to eliminate mosquito sources on your property and use insect repellent that works. Insect repellent should have one of the four active ingredients recommended by the CDC, which include: Picaridin, DEET, Oil of Lemon Eucalyptus, and IR3535. If you are traveling to a country with an ongoing dengue outbreak, it is extremely important to use insect repellent while you are there and when you return from your travels to prevent spreading any disease locally. Visit the CDC website to see what areas around the world are experiencing dengue outbreaks: LEARN MORE What type of mosquito can transmit Dengue? Aedes mosquitoes (ankle biters) are capable of transmitting dengue, Zika, chikungunya, and yellow fever. Here in the San Gabriel Valley, we have three types of invasive Aedes mosquitoes: Aedes aegypti, Aedes albopictus, and Aedes notoscriptus. Aedes mosquitoes are agressive, black-and-white insects that thrive in our cities. Aedes are also called "ankle biters" due to their behavior of biting people near the feet. Learn more about Aedes mosquitoes and how they're different from our native mosquitoes: LEARN MORE What is the best mosquito solution? There may be two reasons why you keep seeing mosquitoes in your yard or patio: sources and resting sites. Mosquitoes only need a SPOONFUL OF WATER and five to seven days of perfect weather to go from mosquito egg to flying adult. We urge residents to practice these simple steps to create a bite-free home: TIP, TOSS, and PROTECT: TIP out standing water at least every five days. TOSS out any unused containers that may collect water. PROTECT yourself using loose-fitted clothing and wearing insect repellent that has one of the CDC-recommend active ingredients: Picaridin, DEET, IR3535, Oil of Lemon Eucalyptus.
