Homes around the Toledo Bend Reservoir in Northwestern Louisiana were treated with low and high rates of bifenthrin as described on the package of Talstar�. 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.
