Flea prevention treatment for humans involves ridding their homes and pets of fleas. Insecticides applied to pets, homes and yards kill off both fleas and eggs that hatch following the initial usage, as Healthline explains.
The best way to keep away from fleas outdoors is to stay away from areas where fleas thrive. These pests enjoy moist and shaded areas, such as spaces close to a porch or around sheds. Another popular area to find fleas is in tall grass, according to Healthline. If a large outdoor flea population exists, pesticide application can eradicate the pests. Do-it-yourself options are available, but a severe infestation may require professional treatment.
