Homes around the Toledo Bend Reservoir in Northwestern Louisiana were treated with low and high rates of bifenthrin as described on the package of TalstarŪ. Using the high rate, we also compared the efficacy of treatment at homes that were <0.5 acre to those that were >1 acre. Pitfall traps and honey cups were used to measure percent forager reduction. The low rate of bifentrhin reduced >70% Argentine ant foragers for four months. Greater reductions were acheived with bifenthrin at the high rate on small-scale and large-scale plots with >80% and >93% forager reduction, respectively. Bifenthrin is effective in reducing Argentine ant foragers for up to four months in northwestern Louisiana.
