It may be your first instinct to reach for a can of pesticide when you see those little black insects inside your house.

Prevent ants from coming into your home by eliminating food and water sources. Remove any food that has been left out and sweep up crumbs from tables and floors. If the ants do not find a source of food, they will not come into your house.
Spray ants with a solution of soap and water. This will kill the ants and also remove the pheromone trail they leave for the rest of the colony to follow them into the house.
Put a dirt-filled flowerpot outside your home and place some bread or other food attractant in the pot. Once the ants flock to the pot, burn it to kill them.
Sprinkle cornmeal outside your home and where you see ants. They will eat the cornmeal but cannot process it. While safe for dogs, cornmeal will kill off ants.
Do not use any product that contains boric acid. It is toxic for dogs.
