There is not a specific time that's best to apply Demon WP to your yard for fleas. The important thing is just to make sure that you do a thorough treatment around your yard. Mix one packet of Demon WP to one gallon of water and make sure it dissolves completely before you begin spraying. You will need to re-treat every 14 days as needed for flea control. Most folks find they have to do between 2-4 treatments to get rid of the fleas for good. You may want to look over our Flea Treatment Guide for more tips and information.
