A highly-targeted approach for the control of yellow fever mosquito infestations in Southern California.
We are periodically updating this page. If you have any questions, you can always contact us.
What Residents Can Expect
If you are receiving mosquito bites, it is not related to this program. Protect yourself and your family from mosquitoes:
- Keep tight-fitting screens on your doors and windows to prevent mosquitoes from flying into your home.
- Use insect repellent containing EPA-registered active ingredients such as DEET, Picaridin, and IR3535 when outdoors.
Residents in the areas selected for this treatment program can assist by volunteering their yards as male mosquito release sites and for the placement of surveillance traps for the approximate 10 week duration of the pilot program.
As with all mosquitoes, make sure doors and windows have screens that are in good repair to keep them out.
For residents outside of the program site, our services are still available. We will continue to conduct our control and surveillance activities. This includes monitoring public areas that have stagnant water as well as responding to service requests. The surveillance of West Nile virus activity will continue as well.
We will be in the program area several times per week. This is to release mosquitoes and monitor traps.
All of our trucks are well-marked on both sides with our logo. Staff wear uniforms with a logo, and will have badges prominently displayed. Please feel free to call our office at 562-944-9656 if you are unsure. Safety is priority for our residents and our staff.
We are a governmental agency. Our program is prefunded through a benefit assessment, so there will never be a charge when we come out to help.
About the Released Male Mosquitoes
Pyriproxyfen is approved by the Food and Agriculture Organization/World Health Organization for use in drinking water.
Non-biting, male yellow fever mosquitoes (Aedes aegypti) are dusted with a small amount of an insect growth regulator (IGR) called pyriproxyfen. The males are then released in infestation areas to deliver this dust to both mosquito breeding water sources and female mosquitoes, which will then also carry this dust to breeding sources when laying her eggs.

This approach is better because the male mosquitoes are very effective at locating females and both males and females are very good at locating water sources. This results in a much more targeted approach than traditional treatment methods, meaning less pesticide is used in an infestation area.
This is a much more targeted application than traditional treatment options and promises to be highly effective.
You will not be able to tell the released males apart from wild mosquitoes in your neighborhood. Since male mosquitoes do not bite, you will not experience an increase in biting.
No. The released male mosquitoes have not been genetically manipulated.
