Over 100 fire ant mounds are dead and gone

Hello again,
just to update on two of my customers,our school we are doing ,we have gotten rid of 100+ fire ant mound since we started in mid May. Even after we had around 4 inches of rain over the weekend,we only found 2 new small mounds. It has rain on and off for the last6-8 weeks, but i have been able to eradicate these mounds safely and not pollute everything and save the birds from getting into fire ant pesticides. The other customer on an acre of land, we have eradicate over 53 fire ant mounds since May and found only 1 new fire ant mound this week after this heavy rain in their yard. This is great! Our fire ant trap works and saves the environment and works in the rain.
