My Father in-law was a bit of a greenie so his house was surrounded by large trees, but he always encouraged ants around the house. Reason is whenever he found termites he would put food near the termite trail and once thousands of ants arrived he would put a hole in the termite trail and within days the little ants had eaten the termites in the trail/nest.
In the 20 years of doing this, his house was the only house in his area which didn’t need repair work from termite damage.
Just something to consider
