A method of treating soil adjacent a structure generally includes positioning an injection apparatus over a first injection site generally adjacent a structure. The injection apparatus is operated to inject pesticide down into the soil at the first injection site without prior disturbance of the soil at the first injection site. The injection apparatus is moved over a second injection site at least in part different from the first injection site and generally adjacent the structure. The injection apparatus is operated to inject pesticide down into the soil at the second injection site and without prior disturbance of the soil at the second injection site.
