Residents who are fed up with biting mosquitoes often request the District to adulticide (kill adult mosquitoes with pesticide).
Adulticide spraying is a useful tool in mosquito control, but reserved for severe conditions, including abnormal mosquito population spikes and public health emergencies. In addition, broad-scale treatments are only short-term solutions.
Eliminating stagnant water is the most effective, long-term solution in cities in Los Angeles County. Residents must eliminate stagnant water weekly and maintain a clean, dry yard/patio to prevent mosquito infestations. Our Vector Control Specialists are trained to identify sources of mosquito growth and to eliminate the water first, before even considering pesticides.
Mosquito control is a shared responsibility
Trying to eliminate every single mosquito from your neighborhood may be impossible, but together, we can all work together to reduce the threat.
