nerally speaking it is advisable to only use this type of treatment in areas where there is little or no human traffic. If broadcast treatment is used in such an area, a good choice is growth regulator bait, which poses much less risks to non-target species. For example, fenoxycarb bait has been shown to be very effective for suppression of fire ant populations when applied in one application over a wide area.
