If a walk in your backyard leaves you with itchy skin, you may have a flea problem. Fleas are tiny jumping insects that are attracted to blood in humans and pets. Fleas can be eradicated with a combination of flea population reduction strategies and insecticides.
Keep your lawn mowed to its proper height as appropriate for the specific species of lawn grass. Remove any debris and overgrown vegetation, which increases the level of sunlight in the yard and deters fleas.
Water the lawn thoroughly with a heavy soaking once a week. Fleas drown easily, and this will significantly reduce the flea population and minimize the need for chemical treatments.
Treat the lawn with a pyrethroid-, permethrin- or pyriproxyfen-based flea treatment. Apply according to the label's guidance, as toxicity varies by product. Focus on shaded areas and areas such as outdoor kennels or outdoor doghouses that are frequented by pets.
Apply the flea insecticide again three weeks after the initial application. This helps catch any fleas that may have hatched from dormant eggs since the first application.
