To save money, you can use borax laundry detergent mixed with sugar in a 5:1 ratio (sugar:borax) and dilute the mixture in just enough water to make a syrup.
Fill a bottle with the syrup and every other day, go pour some of the syrup on top of plastic container lids located in high population area (of ants) and near the infected trees.
