Mosquito dunks are to be placed in standing, stagnant water around homes. They contain a larvacide that lasts for about 30 days, killing mosquito larvae before they become adult mosquitoes. Dallas County makes them available at no cost to residents through the Cedar Hill Community Services desk on the second floor of the Government Center. One packet per residence, please.
To help avoid exposure to mosquitoes that may be carrying WNV, residents are encouraged to practice the 4Ds to reduce the risk of WNV:
DEET All Day, Every Day: Whenever you’re outside, use insect repellents that contain DEET or other EPA approved repellents and follow instructions.
Dress: Wear long, loose, and light-colored clothing outside.
Drain: Drain or treat all standing water in and around your home or workplace.
Dusk & Dawn: Limit outdoor activities during dusk and dawn when mosquitoes are most active.
Preventing mosquito breeding areas around your home by emptying all standing water and cleaning up piles of leaves and grass clippings.
