I use 1 cup warm water, 1/3 cup sugar, 1T Borax, mix altogether dip cotton balls in it and put on something and put where you see ants. This really works-it turns them into little black rice crispies!
I would like to know how to get rid those pesty little sink/drain flies. I've tried baking soda and vinegar, drain cleaners and put plastic over the drains.
