Jacumba Eye Gnat Project

Residents in Jacumba have submitted complaints about eye gnats impacting their quality of life. The County of San Diego recognizes the concerns of the homeowners and residents of this community in relation to large eye gnat populations generated from nearby agricultural activities.

In response to community needs the University of California Cooperative Extension, San Diego County, was tasked with understanding the dynamics of the increased eye gnat population in Jacumba. Several emergence trials were conducted which resulted in the development of eye gnat population reduction recommendations for the farm.

These recommendations are now recognized as the “Eye Gnat Nuisance Prevention Plan (2010)." The University of California will continue to work on the site to evaluate the effectiveness of the plan. The County of San Diego Vector Control Program will monitor compliance of the farm with the plan. Both the Eye Gnat Nuisance Prevention Plan (2010) and the weekly compliance checklist are posted below.

It is helpful if you include the following details in your report: the date, time of day,  location, an approximate number of eye gnats, and climate conditions, including temperature and wind.
