 Adult Mosquito Treatment Planned for November 4th

Due to elevated mosquito abundance, the District will conduct an adult mosquito

spray treatment on November 4th., 2021. The spray application will be

conducted between the hours of 3:00 am to 5:00 am at the following location:

the residential neighborhood located in the City of Lake Elsinore, South of

Rosetta Canyon Drive and North of Waterford St, situated between Diana Ln.

and Pascali Ln. Please see attached images for the exact spray route. 

The District will be treating this area with DeltaGard (EPA Reg.

432-1534), which is approved for use in mosquito control by the US EPA.  We

have been working hard to use Integrated Vector Management Practices in this

area and the majority of our control efforts focus on preventing mosquito

breeding and killing mosquito larvae before they become flying adults.

However, due to elevated vector-borne disease risk, an adult mosquito

control treatment via truck mounted ground fogger will be employed to

control the current mosquito population in this area. Signs will be posted

on November 2nd., 2021, in the spray area to inform the public of our

activities.  Information regarding the treatment will be posted on our

website at If there are any questions or concerns,

please contact the District at 951-340-9792.
