Bye bye ant Hill

We have a huge ant Hill infront of my son's bedroom window that we want gone so basically what It is composed of dirt, tiny rocks, sand, clay, and various types of decomposed organic material. Ant hills are a result of the queen and worker ants trying to establish a safe home for the entire colony

so we removed the top layer of the active nest this displaced soil compost

tilled the soil looking for eggs and other large patches of ants.

I was told to add very hot soapy water to the nest sight and that will help deture them from returning and make the water stick to their bodies and they will drown.

then once the soapy water was obsorbed to add salt or boric acid around the base of the affected area we tried salt and then wait if no change repeat and dig down deeper .
