Though considered to be social insects, ants lack all traces of social etiquette by inviting themselves into places they don’t belong. If you happen across an ant in your house, the first thing that usually comes to mind is wondering where the rest of them are; very seldom is there ever just one ant. Getting rid of ants is easily accomplished with all of the pesticides available commercially, but these things aren’t safe to use around your four-legged companions. For those with pets, there are effective alternatives to keep ants out.
Sprinkle dry grits or cornmeal in places that ants have been spotted. They will take this back home and not be able to digest it, killing many ants right at the source.
Dig the ant's nest out of the ground and dump it into a bucket. Pour boiling water into the bucket to kill the ants. Be sure to wear a long-sleeved shirt and pants, as the ants may not want to be too cooperative with this method.
Use a shovel to dig up as much of the ant pile as possible and set it on top of another ant pile. They go to war, and you win as they destroy each other so you don’t have to.
Boil 2 or 3 rhubarb stalks in a gallon of water for half an hour. Once it has cooled, add a teaspoon of dry soap flakes and strain the solution before putting it into a spray bottle as a pet friendly insecticide.
