Flea infestation in your yard may be dealt with in a number of natural ways that will not hurt you, your pets or the environment. Fleas are not only pests, but carriers of disease and parasites such as typhus, bubonic plague and tapeworm. Simple ground preparation and natural methods of elimination are all that are needed to rid your yard of the larvae that hatch into blood-sucking fleas. Once you have broken the life cycle, you and your pets can enjoy a flea-free yard.
Diatomaceous earth is a natural pest control that kills fleas and their larvae within a few hours of contact. Made from the fossil remains of algae from the dinosaur era, diatomaceous earth is readily available for purchase in garden departments, health food stores and on-line. To prepare your yard, move objects and rake up dead leaves and debris, exposing the earth beneath where flea larvae are hidden. Sprinkle the diatomaceous earth powder all over the yard, paying attention to dark recesses and cracks where fleas and their larvae like to breed.
Grassy and moist areas of your yard are ideal breeding grounds for fleas. Breaking the flea's life cycle with agricultural lime dehydrates fleas and their larvae. Prepare the area by raking debris and leaves into piles and either sacking or burning the waste. Sprinkle the lime evenly over your entire yard as larvae may lie dormant for up to 90 days before hatching.
Keeping your grass short and wet creates an unfriendly environment for fleas. Watering your grass regularly drowns fleas and their larvae that are trying to infest your yard. You may not have to water your yard as much if you live in a climate with plentiful rainfall, but in arid areas such as the desert southwest, a regular watering schedule is necessary.
Boric acid, which is inexpensive and readily available at hardware and department stores, is an effective way of ridding your yard of fleas and larvae. Prepare the area by raking dead leaves and debris and sprinkling the boric acid powder over it. Some people and pets may be sensitive to boric acid, so test patch may be conducted before treating the entire yard.
