Rationale
-
Fleas don't only cause your pet to itch; they can also infect your pet with parasites. Thus, it's important to remove fleas from your pet's environment. However, pesticides can harm your pet. For instance, if you spray your yard with chemicals and Fido then goes for a romp, some of those chemicals will end up on his paw pads. If he then licks his paws, he will ingest the harmful chemicals.
Organic Sprays
-
Various companies sell "organic" flea treatments that can be sprayed on your yard. One such company is the Cedar Cide Store. When buying such a product, always read labels to ensure that the product is in fact all-natural. Look for products made with cedar oil.
Nematodes
-
One of the easiest and least expensive ways of getting rid of fleas in your yard is to populate your yard with nematodes. These are tiny worms that thrive in the shade, which is where fleas are most likely to be, since they do not like harsh sunlight. They destroy flea larva, decimating the flea population in your yard. Nematodes can be added to your lawn by putting them into a sprayer with water and then spraying your entire yard.
Diatomaceous Earth
-
Another popular and completely natural way to treat an outdoor flea infestation is by spreading diatomaceous earth around your yard. This is the ground-up shells of marine fossils. They kill fleas by making tiny cuts on the fleas' outer shells and dehydrating them to death.
Considerations
-
To boost the effectiveness of any natural flea treatment you try out on your yard, consider some basic yard maintenance first. Get rid of weeds that may give fleas shade to thrive in, and mow your grass. Additionally, inspect your fence for holes to make sure no raccoons or other small animals that typically carry fleas are getting in at night.
