Buena Vista Nature Center, Lagoon and Laguna State Park

The Lagoon spans 17 acres, and is regularly sprayed for mosquitos from April through October, like all the other north coastal lagoons. The spray contains a bacillus bacterium that kills mosquito larvae when they feed on the spores.

In 1997, for the first time in many years, the Buena Vista Lagoon Foundation and the state Department of Fish and Game are trying to eliminate much of the marsh plants which have prevented the lagoon from being fully sprayed for mosquitos. Crews first cut down lagoon plants, and then spray a herbicide to kill the plants.

Here are the number of mosquitoes caught in county traps since 1994:

DateCulex erythrothorax
Common mosquito
Anopheles hermsii
Malarial mosquito
6/13/941800
8/8/944200
6/21/9524000
7/18/9597616
6/26/967360
7/22/966728
6/3/978400
7/29/9770732
6/2/9814400
7/28/98220
6/29/9959713
7/27/9937648
6/6/0069624
