Per the product label for CSI 4 - 4 Mosquito, Fly & Gnat Control: Apply at a rate not to exceed 0.007 pounds of permethrin per acre in any given 24 hour period. Do not retreat a site more than once in 3 days. Do not exceed 25 applications at 0.007 pounds of permethrin per acre (not to exceed a total of 0.18 pounds of permethrin per acre) in any given season. So you should wait at least 3 days between treatments and not exceed the max rate per acre in any season.
