Control of a Natural Infestation of the Pharaoh Ant (Hymenoptera: Formicidae) with a Com Grit Bait of Fenoxycarb

The insect growth regulator fenoxycarb was very effective against a natural infestation of the Pharaoh ant, Monomorium pharaonis (L.). 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
