My mother in law pours boiling water over them when they get in the house, but I've always thought that was kind of mean. I think it works though, if that's a help?
i'm going to need a lot of boiling water! we have ant nests all over the back yard... sigh.
mmmm, i don't know any non-toxic - we always used gasoline
There is natural citrus bug spray called Orange Guard that you can buy. http://www.orangeguard.com/I have used it inside my home for ants before and they have never come back.Or you could try the suggestions on this website:http://www.eartheasy.com/live_natpest_control.htm
