UPDATE: We have used the spray in the kitchen area, and definitely see a difference. The spray is so much nicer than the typical sprays available. Smells better and works as good, I will be making more.
We are testing the theory that orange peels soaked in vinegar for two weeks in a dark cupboard will produce a solution that will eliminate ants. In two weeks you drain, throw out the peels and add water 1:1. If you have a cup of vinegar you add a cup of water then put in a spray bottle. Made ours today and will update in two weeks.
