Depending on your application method, the label gives specific details for rates and timing. One example: The 8 ounce bottle of EcoGuard Plus will treat between 1 and 1.5 acres.(44,000ft2 to 66,000ft2) If your lawn and landscape area is 10,000ft2, the 8 ounce bottle will allow you to treat approximately 4 to 6 times depending on your application method. If the average time between applications is 30 days, your 8 ounce bottle would fight insects for 4 to 6 months!
