Public Health Pesticides

The District uses an Integrated Vector Management (IVM) program, which is core to a mosquito management plan. The main goal is to remove sources of stagnant water and to educate our residents to take action in their own homes and backyards. However, in some cases, it is necessary to use pesticides against mosquitoes because the risk of human disease is too high.

Our decisions regarding pesticides, such as where and when they are used and how they are applied are based on science and heavily monitored and regulated by the California Department of Pesticide Regulation and Los Angeles County Agricultural Commissioner / Weights and Measures.

A vast majority of our pesticide use is against mosquito larvae using organic pesticide Bti (Bacillus thuringiensis var. israelensis)

We select pesticides which are most effective against the vector which must be managed, have the least side effects, and best reduce the risk for human illness. We also carefully rotate the selection we have to reduce pesticide resistance in mosquitoes found in San Gabriel Valley.

Our agency commonly uses mineral oil to target mosquito larvae

The information below displays products that are available to mosquito control programs in California,

This is NOT a list of what the District uses in the field every day. Please check out our public Board of Trustees report to see what products we use monthly.

Education is the best tool against mosquitoes

 

Most Used: Controlling larvae

When removing stagnant water isn't possible, Vector Control Specialists use larvicide (pesticide that target mosquito larvae).  Most of the mosquito control pesticides the District uses are mineral oil and a soil bacteria called Bti, which is also used in organic farming.

LEAST Used: Controlling Adult Vectors (Capable of Spreading Disease)

In situations when the District observes abnormally high population of mosquitoes or during public health emergencies, adulticides (pesticides that kill adult vectors) may be used. This is only as a last resort when eliminating the water and larvae are ineffective responses.
