Along with the hot summer weather also comes the peak of mosquito season.
The city of Irving has adopted guidelines for “adulticiding” or spraying to kill adult mosquitoes. According to the city’s website, Irving has adopted the U.S. Centers for Disease Control (CDC) recommendations for its mosquito control guidelines when it comes to adulticiding.
The city says it uses the CDC parameters in deciding whether a vector control technician will be sent out in the evenings for truck-mounted adulticiding spraying.
According to the city, the adulticiding spray unit is used when a trap shows over 100 female mosquitoes in one night or when one trap’s catch shows a pool of mosquitoes that have tested positive for West Nile virus or Saint Louis Encephalitis. The city will also use the adulticiding method when local or state health departments suspect or confirm a human case of West Nile or Saint Louis Encephalitis.
“Though most U.S. cities used adulticiding throughout the latter half of the 20th century to reduce nuisance mosquitoes, those species that bite humans normally don't carry disease,” the city said on its mosquito control program website page. "Nuisance spraying is heavily discouraged by state and federal health officials."
The city says anyone who is concerned about exposure to a pesticide, such as those with chemical sensitivity or breathing conditions, should stay indoors during spraying which is usually done during nighttime hours.
