Hydrated lime is available at lawn and garden stores and at lumberyards. It is important to ask specifically for hydrated lime and to follow directions on the container carefully. Children and animals should be kept away from limed areas until the lime is no longer visible. Outdoor furniture, barbecue grills and equipment should all be cleaned carefully. 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.
