The Garland Health Department (GHD) recently received a report of laboratory confirmed presence of West Nile Virus (WNV) in mosquitoes collected in the 4000 block of Gatewood Road, 75043 (GA25). GHD immediately initiated adulticide spraying throughout the surrounding area Aug. 17-18 to minimize the risk of human infections. Spraying will be conducted between 9 p.m. and 6 a.m.
No WNV human cases have been confirmed in the city of Garland thus far. However, the presence of the disease in mosquitoes means that transmission to humans is possible, so residents are urged to take preventive measures.

MOSQUITO TRAPPING AND SPRAYING MAP

TRAPPING
Mosquito trapping occurs year-round, but is increased during late spring and continues until mosquito activity decreases; usually in early fall. The GHD uses sentinel or “fixed” sites for trapping locations instead of changing locations based on complaints. A Center for Disease Control and Prevention study conducted after the 2012 West Nile outbreak in North Texas recommends that only stationary sites be used in order to have accurate weekly data of mosquito activity.
The trapped mosquitoes are sent to the Dallas County Health and Human Services laboratory where they are tested for the presence of West Nile Virus and other vector-borne diseases.
STANDING WATER
The GHD asks all citizens to eliminate any standing water on their property, such as:
- birdbaths (clean them twice per week)
- buckets
- clogged rain gutters
- pet water dishes
- tire piles
Containers that can hold an inch or two of water can breed mosquitoes. Report standing water that you cannot eliminate yourself to the GHD. If you have questions or would like to report dead birds or standing water, call the Garland Health Department mosquito hotline at 972-205-3720 or send report through the Garland eAssist app.
