We had pesty ants mainly because the house was unoccuplied before we bought it for 5 years. The only way they got rid of (most of them - and it's been a year) is by treating all around & inside the electrical outlets because they live in the walls. Still from time to time my 'glue traps catch some. Massey gives them to you if you use their service. I couldn't tackle them myself - I had no clue. I haven't seen them in a month - on or around the front door - so keeping my fingers crossed - but still spraying in between outside the door myself.
