The purpose of this study was to involve pest management professionals in the design application techniques and strategies that would be efficacious also reduce insecticide runoff. Our involved measuring both efficacy treatments for Argentine ant, Linepithema humile (Mayr), concurrent runoff fipronil pyrethroids. Two collaborating companies used low-impact protocols controlling ants while minimizing Protocol 1 bimonthly treatments, 2 monthly. Both an initial treatment with a spray around foundation. At garage door-driveway interface, done as pin stream 1, crack crevice expansion joint near 2. replaced most pyrethroid sprays bifenthrin granules placed bushes away from driveway. For next on day 63, included cyfluthrin house foundation applications edge first 2, supplemented spot cyfluthrin. subsequent botanical insecticides were applied. weeks posttreatment combined, had significantly higher reductions ant numbers compared Thereafter there no significant differences between protocols. Runoff much lower than previous trials involving sprays. Day 1. This difference may because applied Cyfluthrin minimal which supplement or treatments. large peak at 63 corresponding their driveway
