The Q&A Archives: Ridding Yard of Fleas Organically

Question: How do I organically get rid of the flea infestation that keeps me from being in the yard?

Answer: Pyrethrum and related products like pyrethrins are toxic to fleas. They are sold under various brand names. Beneficial nematodes have also been shown to be effective outdoors against the larvae of fleas which are developing in the turf or at the soil surface.

Insect growth regulators, although not organic, are very popular and effective. Two examples are the products Archer and FleaFix. They do not kill fleas, but rather prevent the development of fleas from eggs to adults, thereby shutting down the flea outbreak. They are used at very low rates so people wishing to reduce pesticide use often prefer them. Make sure and select one labeled for outdoor use.

If you have indoor pets, in order to win the war on fleas you must simultaneously treat the pet and the outdoor and indoor areas. Effective flea control is based on stopping adults as well as developing eggs, larvae and pupae. This will take more than one treatment in most cases. Otherwise in a few weeks you are back where you started.
