The Garland Health Department (GHD) received a report of laboratory confirmed human case of West Nile Virus (WNV) in an individual who resides near the 100 block of North Jupiter Road (GA07). GHD will treat the area with adulticide to reduce the mosquito population the evening of Oct. 10 and 11 between 9 p.m. and 6 a.m., weather permitting. GHD will also continue to monitor for the presence of WNV throughout Garland.
Thus far in 2018, WNV has been detected in 26 mosquito samples trapped by GHD. Eleven (11) WNV human cases have been confirmed in Dallas County, two in Garland residents: 3200 block of Bending Oaks Trail (GA13) and 7400 block of Wellesly Ave (GA11). The presence of the disease in mosquitoes means that transmission to humans is possible throughout the city, so residents are urged to take preventative measures. Citizens can view a map depicting areas where WNV has been detected and subsequently sprayed to reduce the adult mosquito population at the link below.

The Garland Health Department has improved our mosquito surveillance program by using sentinel or “fixed” sites for our mosquito traps instead of changing locations weekly based on complaints. This change is a result of the CDC study that was conducted after the 2012 West Nile Virus outbreak in North Texas. The CDC recommends that only stationary sites be used in order to have accurate weekly data of mosquito activity in the community.
The Garland Health Department asks all citizens to eliminate any standing water on their property, such as birdbaths (clean then twice per week), pet water dishes, clogged rain gutters, tire piles, and buckets. Containers that can hold an inch or two of water can breed mosquitoes. Report any standing water that you are not able to eliminate yourself to the GHD. If you have questions or would like to report dead birds or standing water, please call the Garland Health Department Mosquito Hotline at 972-205-3720.
The GHD controls mosquitoes in three ways: Environmental Health Specialists (EHSs) require property owners who possess breeding sites (containers of water or standing water) to remove the breeding sources. EHSs also treat standing water (a control method called larviciding) with agents which kill immature mosquitoes (the larvae or "wigglers"). To reduce adult mosquito populations, the GHD sprays a low-toxicity pesticide from a truck-mounted, low volume sprayer (a control method called adulticiding).
The GHD has analyzed technical and toxicological data on essentially all known, currently available EPA-approved mosquito adulticides. The only pesticides the GHD uses for spraying are those which contain man-made derivatives of pyrethrins (e.g resmethrin or permethrin). These formulations, when mixed and sprayed according to label directions, are considered by the US Environmental Protection Agency (EPA) to be safe with respect to adults, children, and pets.
