Thankyou so much for the info. I am going to try it, since I have some pine tar soap.I grate 1/3 of a bar of pine tar soap and dissolve it in 4 cups hot water, put it in a spray bottle and spray around the house where I see ants. It doesn't only repel, it kills, so better yet if you find the nest where they're coming from. You may have to spray more than once but then (at least for me) they're gone!
Here is a pic of part of my view, but it is not pretty today. On clear days we can see Santa Catalina Island and once in a while San Clemente Island
