The city of Irving continues its aggressive mosquito control action plan and officials have authorized vector control technicians to conduct nightly truck-mounted, ground-level spraying in all Irving ZIP codes until the region’s severe seasonal West Nile Virus outbreak has subsided. City officials have revisited the possibility of aerial spraying and have accordingly resubmitted a proposal to Clarke, the contractor working with the Department of State Health Services to administer aerial spraying. In response to Irving’s second submission for proposed aerial treatment, Clarke Spokesperson Laura McGowan stated the following: “After conferring with the Department of State Health Services, the recommendation is to have these areas treated via ground application versus aerial spraying.”

Earlier this month, Irving vector control technicians were told by Clarke officials that the city’s proposal to aerially treat 3,800 acres fell short of minimum thresholds established by the supplier. At that time, the City of Irving continued with heavy ground-level spraying in high-risk areas as the most effective course of action. Since Irving’s aggressive watch for West Nile Virus began at the onset of mosquito season, the following actions have been taken by vector control authorities: set 70 traps for mosquito testing between April 15-Aug. 23, completed more than 30 truck-mounted, ground-level spraying in areas meeting established guidelines, and Commenced precautionary truck-mounted, ground level spraying in one Irving ZIP code per night since Aug. 21 for a total of five precautionary sprayings to date.

The most recent data collected continues to indicate that the West Nile Virus threat is not as widespread in Irving as it is in some neighboring cities. However, Irving vector control technicians remain on high alert. The latest inventory of supplies at Irving’s vector control headquarters indicates that the city possesses a full supply of spray for immediate use and more-than-enough larvicide products to continue addressing one of the most intense mosquito seasons experienced throughout Texas in decades. In addition, city vector control technicians have been talking one-on-one with residents, working overtime, conducting ground-level spraying early in the morning and late at night, making house visits, and will continue taking the necessary actions to protect the health and welfare of the Irving community.

As the city’s aggressive West Nile Watch continues, city officials will continue to work with authorities for the best recommendations going forward. Residents should not hesitate to call the City of Irving’s Mosquito Hotline 24/7 at (972) 721-3755 if they feel that their neighborhood needs additional attention. In addition, residents are strongly advised by city officials to exercise caution by adhering to the Four D’s (Dusk/Dawn, Dress, DEET and Drain).
