Imported fire ant workers forage for food only when conditions are favorable. This occurs when air temperatures range from 65 to 90 degrees F. In the heat of the summer, foraging occurs predominantly at night so baits should be applied in the late afternoon or early evening. During winter months and times when colonies are not actively producing brood, attractiveness to baits may be reduced. At certain times, some colonies may be more attracted to other available food sources and will ignore the bait. When in doubt about product freshness or presence of foraging behavior, place a potato chip or a small pile of the bait near a fire ant mound. If ants are carrying off bait particles or the potato chip within 30 minutes or so of placement, the time is right and the bait is attractive.
