Remove loose dirt and debris from affected surfaces with a power hose. Hardware stores sell power spray attachments for regular garden hoses. Rinse thoroughly with a power hose to remove any residue. Don't forget to clean children's toys and playground equipment thoroughly. If your children have a sandbox that was touched by floodwaters, remove all the sand, disinfect the box with the chlorine bleach solution, and refill with new sand.
Mosquitoes can carry many diseases and a flood can create ideal conditions for mosquitoes to breed.
Drain or remove standing water because it can become a mosquito breeding ground. Dump water out of barrels, old tires, and cans. Check to be sure that your gutters and downspouts are clean and can drain effectively. Ditches and drains also need to be flushed so they can carry storm water away from your house.
