I have used Reiki in our household in one practical way that has been appreciated by our whole family. Several times last year the ants in our area came inside looking for food. We would come into the kitchen in the morning and find overwhelming numbers scavenging everywhere. We had never experienced much difficulty with ants and certainly not in such tremendous numbers.
Of course, I did not want to hurt them. Instead I sent Reiki to them to help them find food in other places and told them in a kind but firm way that they were not welcome indoors and please to move back outside. The next day there were markedly fewer ants inside and the following day all of the ants had left. I thanked them very much for their cooperation and, of course, Reiki for its invaluable assistance once again.
