I'm looking for something that's simple to make and nontoxic, as I have several cats and a dog. The ants we have are just the typical black ants that seem to show up in all kinds of homes in the spring. We get them every year, and have a pretty decent amount of them. We don't know where the nest is, but we think they are accessing our home through the wall behind our dishwasher(which we can't access), so our only option is to get them to bring poison back to the nest. Any suggestions?
