Op, I’m the pp with ants.
Had to come back and report what I did and it was effective. I have been using terro for about two weeks, but after I saw your message, I went out and bought ortho, Homedefense insect killer.
They were invading the kitchen and last night we sprayed everywhere and heavy-handed. This morning we woke up with no ants! This is the first time in 3 to 4 weeks with no ants. So before you hire someone that might be a good last ditch attempt to do it yourself.
