Mosquitoes from a routine trap in Pasadena tested positive for West Nile virus, according to the San Gabriel Valley Mosquito & Vector Control District.
The District advises residents to stay bite-free by eliminating all stagnant water and using repellent.
“Mosquito bites should be the last thing you should worry about as we kick off summer,” said District Communications Director Levy Sun. “Unfortunately, higher temperatures can mean more mosquito and virus activity.”
Mosquito control staff will continue to monitor and control for mosquito-borne diseases, Levy said.
He added that residents share the responsibility of mosquito control by remaining bite-free and eliminating habitats, such as dense vegetation and stagnant water, that allow mosquitoes to grow and hide.
In Los Angeles County, the most pervasive mosquito-borne disease threat is West Nile virus. Zika, yellow fever, and dengue fever pose an outbreak possibility due to the presence of invasive Aedes mosquitoes.
“If you’re tired of mosquito bites, the best defense is to use mosquito repellent,” said Sun. “Mosquitoes are present in our city environments, however, you can prevent them from biting by using repellent.”
Only female mosquitoes bite. Female mosquitoes use the protein in blood to create their eggs. In the process of biting, mosquitoes can leave behind itchy bumps and can make people sick.
