2)Sprinkle cinnamon on every ant that you come across; those that survive will take the cinnamon back to their nests and warn their buddies about the danger. Ants absolutely loathe and detest cinnamon and will do just about anything to escape from the wonderful spice.
3)Pour good amounts of cinnamon on thresholds of outside doors to stop ants from entering. Some people have reported ants entering through electrical sockets on walls, so don't forget to sprinkle cinnamon below sockets. If you notice ants entering through cracks; treat the cracks and crevices with cinnamon.
4)Sprinkle cinnamon on window sills, crib legs, and door thresholds of children's rooms to ensure their safety.
Not to my knowledge. You can place ant traps in the areas you see ants. They do work but you have to give it some time
