There are several ways to kill fleas in the yard, including:
-
Flood the yard with water: Flea larvae and eggs cannot survive a flooded lawn. Periodically flooding the entire yard can end the life cycle of fleas and wash away all the feces from adult fleas, decreasing their chance of survival to zero.
-
Use diatomaceous earth: Spread a thin coat of diatomaceous earth all over the lawn. It is non-toxic and kills fleas quickly and effectively. Fleas also cannot develop an immunity to diatomaceous earth.
-
Spray the yard with insecticides: Use an environmentally friendly insecticide to rid the yard of fleas. Protect yourself during this process by wearing masks and protective clothing.
-
Use cedar chips: Spread cedar chips generously all over the yard. Fleas hate the smell of cedar chips, and aligning them along the perimeter of the fence can deter them from entering the yard.
-
Use nematodes: Spray the yard with nematodes, which are tiny, microscopic roundworms that live in soil and plants. They feed on flea larvae and other insects in the yard and are completely harmless to humans, plants, trees, and pets.
It is important to get rid of fleas on pets first before treating the yard. Cleaning the yard, mowing the lawn, and removing organic debris can make it easier to get to difficult areas and ensure that no fleas get away. If you have a heavy infestation, consider calling a local pest control company.
