![]() The economical impact and magnitude of the eye gnat problem in the Coachella Valley prompted authorities to form the Coachella Valley Mosquito Abatement District in 1928. In the past, control methods included poison bait and different types of attractant baits that were placed primarily in agricultural fields. Since 1990, the District has used 8,000 to 10,000 traps per year filled with a nontoxic liquid egg bait to attract and remove eye gnats from agricultural areas and country clubs to reduce nucances of these pests.Įye gnats are very common in warm, dry regions. In the Coachella Valley, they have been a problem since agriculture was first introduced into the Valley. The most common species in the Coachella Valley is Hippelates collusor. They measure approximately 1.5 to 2.5 millimeters in length and are attracted to sebaceous secretions, pus, and blood. Eye gnats are prevalent in the Southern United States, primarily in parts of California and Arizona. The adult eye gnats are non-biting insects. Their persistent buzzing around human and animal eyes classified them as nuisance insects that may cause economic losses by lowering performance of exposed, mostly agricultural, workers. ![]()
