Using the Solo Portable Hand Spreader it goes down easy and being in Florida on flat ground a 5 acre back and forth walk is good enough for the days walk, reload the next day and do another 5 then repeat till done with the 25. Taking up 10 weeks kill time I can not say how the product will work. Hope all goes well with the pro this winter and the growth regulator works so I will not need to do as much area in spring. Will try the plus in spring when activity starts for the quick kill B4 rains. Plan is to work the perimeter of the pastures then yard, barns and pens to see if I can slow down the infestation from outside my property. Knowing only application of product I rated it a 3 for easy of use and saw good uptake by ants.
