The best way to deal with an infestation is to remove the reason for the infestation. Ants came to your home in search of food. This means that you should put food leftovers in sealed containers. You should clean spillages immediately. Take out the rubbish regularly, especially if there are food leftovers inside. Ants have a very keen sense of smell. If they can’t smell food, they will assume it’s not there. This will deprive them of a reason to stay.
