A large building (7,841 m2) containing four separate wings was used to evaluate two concentrations of fenoxycarb (0.5 and 1%) in oil on a corn grit bait. Raid Max Ant Bait was used as a standard for comparative purposes. A separate wing was used for each treatment. One wing received no bait and functioned as a control. Our study demonstrated that 0.5% fenoxycarb in peanut butter oil was more effective than a 1% fenoxycarb bait and Raid Max Ant Bait; this treatment completely eliminated the ants < 6 wk after treatment. Reinfestation in the 0.5% fenoxycarb-treated wing occurred 24 wk after treatment and only at two sites in the area treated. Although Raid Max eliminated the ants < 6 wk after treatment, reinfestation occurred at 12 and 14 wk after treatment. Raid Max baits were applied again at 12 and 14 wk; no ants were detected in this wing after the 14-wk treatment.1 aWilliams, D F1 aVail, K M  uhttps://antkey.myspecies.info/en/content/control-natural-infestation-pharaoh-ant-hymenoptera-formicidae-corn-grit-bait-fenoxycarb
