The chemicals used by this District are listed below. None of these materials has any significant residual activity (pyrethrin degrading within four to six hours, methoprene persisting for about three days, and BVA-2 lasting less than two days).
A list of the pesticides used by the District can be found on our Pesticide Summary page. The pesticides we use are designed to be target specific and cause the least environmental disruption possible when used at the label rates dictated by State and Federal law.
