Eye Gnats

Eye Gnat-Stages

San Diego County Eye Gnat Research & Education Project

Eye gnats can be found all over the country, but they have become a very serious nuisance pest in San Diego County.  The communities of Jacumba and Escondido have been calling county and extension offices in search of some relief to the issue.  However, it is a very difficult issue to mitigate. 

There are numerous flies that are called gnats, but eye gnats are a small fly that hovers and waves back and forth across the eyes, nose, ears, mouth, etc. They need to feed on a protein source such as the mucus found around your eye.  In numbers, they can be very bothersome.  For more information see the links below.
