Public Health Pesticides

The District's primary goal is to remove sources of standing 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.

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.

The information below displays the product, category and  a link to the manufacturer's website.

 

Most Used: Controlling larvae

When removing stagnant water isn't possible, most of the mosquito control pesticides Vector Control Specialists use are mineral oil and a soil bacteria called Bti.

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.
