Remove fecal matter from the yard as soon as possible after it is deposited so the organisms don't have time to move into the soil. Wash your hands thoroughly after removing the matter and disinfect scoopers or shovels with chlorine bleach after use.
Disinfect hardscape areas like patios and sidewalks with a solution of 1part chlorine bleach and 32 parts water. One minute of exposure to the chlorine bleach solution is enough to kill the giardia.
Lay a soaker hose on the lawn during the hottest part of the summer.
Lay clear plastic tarp over the lawn and the soaker hose, overlapping the ends if you use more than one sheet. Dig the outer edges of the tarp 6 inches into the soil to prevent them from blowing away in high winds.
Leave the tarp in place for six weeks. Water under the tarp weekly with the soaker hose to keep the area moist and the temperatures high. Remove the tarp at the end of the six weeks and resume caring for your lawn as usual.
