I noticed more ants inside our house in the last few weeks. I think now due to the drought they are looking for water, since they are not going after any pet food or sugary stuff.

We use diatomaceous earth. It has microscopic razor-sharp spikes that lodge between the plates in the ant's exoskeleton, pierces the connective membranes and causes the ant's internal moisture to dry out, killing them a day or so after they walk through it.

Non toxic, works pretty well.
