Wisdom Granules? Would not work. Sounds like Harvester Ants. There are only 2 things that will work.
1. KM Ant Pro System. This system utilizes a liquid bait that the ants will feed on and die from. It also provides continual protection against invading ants. The average number of stations per acre is 8. So to treat all the acreage, you will need about 20 stations. This is the most expensive method, but also the best in that it kill ALL species of ants.
2. Bifenthrin. Get the 3/4 gallon. Mix Bifenthrin in a "drip" bucket. To make a drip bucket, get a 5 gallon bucket and make a very small hole on the bottom, near the edge. Fill the bucket with 4-5 gallons of water and 4-5 oz of Bifenthrin and place the bottom of the bucket and the drip hole over the mound entrance. Let it drip into the colony until the bucket is dry. This could take a while.
If you treat all the mounds at the same time, the ants can't get away. This means get 10 buckets and do all the mound entrances at the same time. This is about the only thing that will work. It may need to be done a few times to get control. If the ants show up somewhere else, keep treating with Bifen.
Hope this helps.
